Known software and hardware used in the management of trunk oil and oil products, including the control and monitoring system for maintenance and repair of main oil pipelines (SCUTOR), the supervisory control and management system (SDKU), the automation objects of which were the central dispatch, territorial, district and local dispatch points, oil pumping stations (see S. Kutukov. Information and analytical systems of trunk pipelines. / S.E. Kutukov; Ufimsky State Oil Technical University - Moscow: SIP RIA, 2002. - S.63-73; 78-82).

The East Siberia – Pacific Ocean (ESPO) oil pipeline system is the largest project in modern Russia to build an oil pipeline to transport oil to the Russian Far East and markets in the Asia-Pacific region. ESPO-I is the first stage in the construction of an oil pipeline, which includes the construction of the Taishet-Skovorodino branch with a length of more than 2 thousand km and seven oil pumping stations (NPS). The route of the oil pipeline runs through the Irkutsk region, the Republic of Sakha (Yakutia), the Amur region. At present, the monitoring system for trunk pipelines has been implemented and is operating on sections of the BCTO-I TS (see. Lisin Yu.V. Monitoring of trunk pipelines in difficult geological conditions / Yu.V. Lisin, A.A. Aleksandrov // Science and Technology pipeline transport of oil and oil products. - 2013. - No. 2. - 2013. - P.22-27), taken as a prototype.

The disadvantages of analogues and prototype include insufficient reliability in the event of a communication failure, a large amount of transmitted data.

The task to which the claimed invention is directed is to reduce the time for detecting abnormal situations in the pipeline (flow shutoff, leakage, overpressure); the transfer of the main pipeline to a safe state in emergency situations, namely the transition to a mode with lower productivity or an emergency stop, as well as improving the quality of training for operational personnel.

The technical result achieved during the implementation of the claimed invention consists in expanding the operational capabilities, ensuring the reliability and safety of oil pumping, as well as minimizing the influence of the human factor on the management of the main oil pipeline.

The specified technical result in the implementation of the invention is achieved by the fact that in a single control system for the pipeline system "Eastern Siberia - Pacific Ocean-II" (ESU TS "BCTO-II"), including a territorial dispatch point (TDP), regional dispatch points (RDP), local dispatch points (TIRs) and connected by communication channels with controlled oil pumping stations (NPS) located along the main oil pipeline, the peculiarity is that the system contains the upper, middle and lower levels, which They provide control and management of three technological areas (TU-1, TU-2, TU-3) using the IEC-608750-5 protocol, while the upper level has the ESU software and hardware complex in the TDP control center, which includes input-output servers, mathematical model servers and controllers of the TU-1, TU-2, TU-3 algorithms, video wall, firewalls, workstation (AWS) of the dispatcher according to TU-1, TU-2, TU-3, intermediate level - ESU software and hardware complex in the RPD control centers, which include the WWO server yes-output, algorithm controller, mathematical model server; video wall, firewalls, automated workstations (AWS) of the dispatcher, the lower level is the ESU software and hardware complex in the TIR, which includes the input-output server of the microprocessor automation system (MPSA) of the NPS, the input-output server of linear telemechanics (LTM), firewalls, automated workstation (AWS) of the NPS operator, LTM operator and the system for measuring the quantity and indications of oil quality (LACT); in addition, control is provided from the RPD and from the MPE when controlling the technological process of transporting oil from the MPD, while it is possible to transfer the control function to the middle level (in the RPD) or to the lower level (in the MPD) and vice versa, it is possible to return the control function from the middle and lower level (in the DAC), while the average level of the ESU provides the ability to monitor the state of the adjacent technological section of the adjacent RDP, and the lower level provides control and management from MD process oil transportation within the zone of responsibility of the corresponding NPS.

The unified control system for the pipeline system "Eastern Siberia - Pacific Ocean - II" (ESU) TSO "ESPO-II" works as follows.

In ECU TS “BCTO-II” the following modes of control of technical sections are provided:

- full-time - the management of TU-1, TU-2 and TU-3 is carried out from the TPP "Khabarovsk";

- reserve - TU-1 control is carried out from the Belogorsk RPD, TU-2 and TU-3 control is carried out from the Dalnerechensk RPP;

- emergency - from the TIR the equipment of the linear part located in the area of responsibility of the NPS is controlled.

Regardless of the control mode of the technological section, the management of auxiliary systems of the NPS, the selection of the main equipment of the NPS and preparation for remote control is carried out from the TIR.

The information received by the middle and lower levels of the ESU is completely identical to the information received by the upper level of the ESU for each technological site.

The control of its own technological section in the zone of responsibility of the RDP in all control modes is carried out in each RDP by the ESU software and hardware via STM and LTM channels, regardless of the TDP and TIR. Monitoring of the adjacent technological section in the RPD in all control modes is carried out by processing and visualizing the technological data received from the KTS ESU of the adjacent RPD technological data. Data from an adjacent RDP is transmitted through an inter-layer data transport system. Control over your own Champion League section in the TIR responsibility zone, as well as adjacent TIR sections (to neighboring NPS), in all control modes, should be carried out by the ESU software and hardware installed in each TIR through the LTM channel, regardless of the TDP and the RDP.

In the normal mode, the control of the pipeline is carried out only from the LDP, the control from the LDP and TIR is blocked. Data is transmitted to the DACs and adjacent OCTs from the DAC.

In normal mode, the average level of the ESU carries out:

- obtaining information on the progress of the technological process and the condition of the equipment of its technological section and the adjacent technological section of an adjacent RPD;

- blocking the possibility of controlling from the RDP the technological equipment of its technological section;

- monitoring the implementation of the functions of transferring control of the technological equipment of its technological section;

- the release of the possibility of controlling the technological equipment of its technological section from the RPD when establishing the fact that the equipment of the ESU TPP is out of working condition.

In standby mode (in case of emergency situations or planned outages in the TPP), the technological section is controlled from the RPP, in the area of responsibility of which the section is located. Data is transmitted to the CDL and adjacent OCT from the RDP.

In emergency mode (in case of emergency in TIR and RDP), the Champions League section in the area of responsibility of the NPS is managed from the TIR. In emergency mode provides:

- stopping the technological section in the absence of communication with the managing director;

- management of the technological section from the TIR, while the actions of the operators of the NPS (TIR) are coordinated by the dispatcher of the TIR or RDP by telephone and dispatch communication.

The control modes of each technological section should be set independently of each other.

Example 1. With planned outages of technical controls in the TDP that affect only TU-1 (for example, maintenance of the TU-1 algorithm controller) and transfer of control of the site to the Belogorsk DPR, TU-1 will operate in standby mode, and TU -2 and TU-3 - in full-time (control from the TPP "Khabarovsk").

Example 2. In case of emergency in the Khabarovsk road traffic accident and the Belogorsk road traffic control and control transfer to the Dalnerechensk road traffic safety and the TIR, TU-1 will operate in emergency mode, and TU-2 and TU-3 will operate in standby mode (control from the RPD "Dalnerechensk").

The transfer of management functions from a higher level to lower levels in the ESU is automated. The transfer of control between the TDP and the TIR, between the TDP and the TIR, is carried out by a team, which is dispatched by the dispatcher from his AWP, transferring control to the subordinate DT. The actual change of the control mode in the ESU occurs only after the dispatcher taking control, means the ESU confirms the adoption of management functions. The confirmation option is available only after the command to transfer control to the dispatcher transferring control.

In the ESU, it is possible to transfer control functions to a lower level without a command from a workstation of a higher level manager. This feature is available only in case of loss of communication between the DP transmitting control functions and the DP receiving control functions. In this case, in the graphical interface of the workstation of the dispatcher of the control center that takes control, the button for accepting control is automatically unlocked. The transfer of control is carried out by a command given by the dispatcher taking control from his AWP. In the absence of communication between the TIR and TIR, the TIR should take control only after confirming the refusal to transfer the control functions of the RDP by telephone and dispatch communication or the lack of communication with the RDP.

The transfer of management functions from lower levels to higher levels in the ESU should be automated. The transfer is carried out by a team submitted by the dispatcher taking control from his AWP.

The ECU TS “BCTO-II” provides for the implementation of control algorithms in algorithm controllers. Algorithm controllers are located in the Khabarovsk SDP and in the Belogorsk RPD, and the Dalnerechensk RDP.

To control the technological sections of the BCTO-II TS in the normal mode, the Khabarovsk TDP provides for two pairs of mutually reserved controllers - controllers of 2 TU-1 algorithms (primary and backup) and controllers of 3 algorithms TU-2, TU-3 (primary and backup )

To control the TU-1 in standby mode in the Belogorsk RPD, a pair of mutually redundant controllers are controllers of 29 TU-1 algorithms (primary and backup). To control TU-2, TU-3 in standby mode, a couple of mutually redundant controllers should be provided in the Dalnerechensk RDP — controllers of the TU-2, TU-3 algorithms (primary and backup).

Algorithm controllers receive operational information on the status of the process from the I / O servers according to the OPC DA specification. Based on operational data, the algorithm controller software monitors the state of the technological process for emergencies.

In the event of an emergency in the controller of the algorithms, the corresponding protection algorithms for the technological areas are launched. In the process of executing the protection algorithm, the controller automatically generates the necessary control commands for the technological equipment and sends them to the I / O server using the OPC DA protocol. The I / O server transmits the received commands to the LTM controllers and the process servers of the MPSA NPS via the TM data channel over the IEC TCP protocol.

The algorithms controller implements algorithms for automated control of the operating modes of the technological sections of the BCTO-II TS. The command for managing technological modes (start the technological section, stop the technological section, switch from one mode to the mode) is formed by the dispatcher from his workstation. In this case, the dispatcher only needs to select the mode to which it is necessary to switch, and issue a command to switch with the press of a single button.

The command generated by the dispatcher is transmitted from the AWP to the input / output server using the IEC protocol, the input / output server sends this command along with the necessary parameters to the algorithm controller.

Having received the command to control the technological section, the algorithm controller starts the corresponding control algorithm. During the execution of the algorithm, the controller automatically generates the necessary commands for controlling the process equipment and sends them to the I / O server according to the OPC DA specification. The I / O server transmits the received commands to the LTM controllers and the process servers of the MPSA NPS via the TM data channel over the IEC TCP protocol.

The algorithm controller monitors the execution of all actions during the execution of each algorithm.

In the ECU TC “BCTO-II” there is a distributed, multi-level regulatory control system implemented in the TDP Khabarovsk, in the RDP Belogorsk, RDP Dalnerechensk and all TIRs. Control is implemented by the KNP software package. In TDP, RDP, the server part of the software package is installed on the application server (primary, backup), the client part is installed on the automated workplace of the checkpoint. In TIR, the client and server parts operate at the automated workplace of the checkpoint.

Operational data for monitoring regulatory parameters in the server part of the software package comes from the I / O servers TDP, RDP, from the I / O servers LTM and technological servers MPSA. Data is received according to the IEC protocol.

The server part of the checkpoint collects, processes, and stores control data for regulatory parameters. The client part displays the control data on the automated workplace of the checkpoint and allows the data to be entered by the dispatcher (operator).

The server part of the PPC consists of application software that monitors regulatory parameters and provides an interface for configuring the KNI system, a database that stores the KNI configuration and KNI history and is implemented on the basis of the DBMS, as well as the KNI agent that provides interaction with downstream KNP systems (upstream - for TIR) DP, including tracking changes in KNI parameters, acknowledgment, masking operations, enabling / disabling the monitoring of events by dispatchers in all DPs, as well as tracking changes to the charter to the control of regulatory parameters in all control stations. Information on acknowledging, masking, enabling / disabling event control by the dispatcher (operator) is automatically replicated by the KNP agent of this DP to the DP of the lower (higher) levels through the KNP agents in these DPs, to ensure access to this information to dispatchers at all control levels.

Access of the KNI client part to this information is carried out through the DB tables of the KNP server part. Changing the settings of the KNI at the TIR level is blocked and is carried out only at the level of TDP, RDP. When changing the parameter setting at the TDP, RDP level, the KNP agent automatically monitors this change and copies the new setting value to the local DBMS on the TDP and RDP application server and to the local DBMS on the KNP TIR automated workstation. The new settings are automatically applied for use in control algorithms implemented in the server and client parts of the KNI without rebooting the KNI software.

In the existing ECU TS "BCTO-II" reports and summaries are formed:

- in the TDP - on the application server (primary, backup);

- in the RDP on the application server (primary, backup);

- in TIR - on the application server (primary, backup).

Reporting is carried out by the server part of the software package for generating reports according to previously developed templates. The reporting system includes a template development subsystem. Reports and summaries are generated both at the request of the user, and according to predefined schedules. Access to the report server and ready-made reports is carried out by the client part of the reporting reporting software complex. View ready-made reports using Microsoft Excel. The client part is installed on the AWP system users.

In the ECU TSU “BCTO-II” in the TDP, RDP, there is a self-diagnostic system for software and hardware of the ESU of the upper and middle levels of control, LTM controllers, as well as equipment for LPS and LF. The self-diagnosis system performs the following functions:

The backup of network equipment and communication channels is provided, with the exception of the network equipment of the training complex. Power supply of all ESU hardware in each power supply is provided from one UPS organized according to N + 1 topology.

The function of providing a single time.

The function of calculating volumetric and mass indicators of the presence of oil. In the ESU, at the level of TDP and RDP, the calculation and display of volumetric and mass indicators of the presence of oil in tanks and tank farms is provided taking into account the technological maps of tanks and oil quality indicators. The calculation is made in the application server. Data display is provided on the dispatcher workstation in accordance with the requirements of the album of typical screen forms.

The possibility is provided for: manual input of oil quality indicators by reservoirs; manual data entry on technological maps of tanks; software configuration for calculating volumetric and mass indicators of the presence of oil in tanks and tank farms directly on the application server, as well as with an electronic engineer workstation.

In the ESU, self-diagnostics of all software and hardware of the ESU are provided (including ESU algorithm controllers). PLCs of the LTM system transmit diagnostic information about their status to the I / O servers of the RDP and TDP, and the I / O servers of the LTM TIR. MPSA NPS transmit diagnostic information about their condition to the MPSA I / O servers. Diagnostic information can be viewed on the workstation of an electronics and monitoring engineer (in the TIR) and on the monitoring workstation (in the RDP and TDP).

The dispatcher support system has a self-diagnosis subsystem of its own funds of the upper and lower levels, with the results displayed on the dispatcher support workstation. According to the results of self-diagnostics, the signals “SOU is good” are formed for each section from the NPS to the NPS separately. This signal means that the dispatcher support system fully performs the functions of the JMA for detecting leaks in the area from the NPS to the NPS. These signals are transmitted to the ECU controller. I / O servers automatically monitor for communication with the PLC. In case of loss of communication with the PLC, a message about this appears on the monitoring workstation, all data from this PLC is displayed as invalid on all workstations.

At all levels of the ESU in the application servers there is a software package for the centralized collection of diagnostic information on the operation of the ESU software and hardware regarding the operation of servers and workstations. This information is available for viewing on the automated workplace of an electronic engineer and monitoring (in the TIR) and on the automated workplace of monitoring (in the RDP and TDP). All software has built-in diagnostics that allow recording information about malfunctions in the operation of ESU software and hardware (in the part of operation of servers and workstations) in the application log of the operating system.

Display information on the video wall. The ESU provides for the display of information on the video wall posted in the DDP in each DDP. The video wall 10 in the TDP is eight liquid crystal panels.

Video wall 36 in the RDP is two liquid crystal panels:

- the first panel is connected to the AWP 37 dispatcher. The panel displays the general scheme of the technological section;

- the second panel is connected to the workstation 40 dispatcher support. The panel displays a mimic diagram of the hydraulic slope of the technological section.

At all levels of the ESU TS BCTO-II, a unified Moscow time is provided. Regular synchronization is performed as follows:

- in the TDP, RDP and TIR, the exact time hardware servers must be installed, the scales of which are synchronized by the time signals of satellite radio navigation systems;

- hardware servers of exact time ТДП, РДП and МДП should provide synchronization of time scales of all hardware ESU on the protocol of network synchronization NTP;

- the time scales of the LTM controllers are synchronized from the signal receivers of the satellite radio navigation systems installed with each LTM controller. In case of failure of the signal receiver of the satellite radio navigation systems, the LTM controllers switch to time synchronization via NTP from the TDP exact time servers, as well as the RDP and TIR, in the service area of which they are located;

- time scales of seismic stations are synchronized from signal receivers of satellite radio navigation systems installed with each seismic station. In case of failure of the signal receiver of satellite radio navigation systems and seismic stations, they switch to NTP time synchronization from the servers of the TDP seismic stations, as well as the RDP and TIR in the service area of which they are located.

TIR domain controllers provide synchronization of time scales of servers and workstations in TIR based on the standard Windows time service (SNTP protocol).

The dispatcher support system with the SDA functions provides information support regarding monitoring the correspondence of the actual values of the technological parameters of the BCTO-II TS operation to the calculated values obtained using the mathematical hydraulic model, as well as providing continuous monitoring of the tightness of the BCTO-II TS.

In the TDP and the RDP, a dispatcher support system with SDA functions is implemented. The system includes a dispatcher support workstation and a mathematical model server. The dispatcher support system receives operational data from the I / O server about the current state of the technological process and transmits to the I / O server the calculated values of pressures (pressure), signals about protection and alarm activation, signals about the achievement and termination of station stationary mode.

Manager Support System:

- determines the calculated distribution of pressure (pressure) along the length of the technological section of the pipeline for the current time according to the embedded mathematical hydraulic model of the pipeline;

- determines the actual distribution of pressure (pressure) along the length of the technological section of the pipeline for the current time;

- Performs automatic control of compliance with the calculated and actual values of pressure (pressure). In the event that a deviation of the actual pressure value from the calculated value is detected (a decrease of 0.45 * kgf / cm ² or more or an increase of 1.8 ^* kgf / cm ² or more (* these values are settings of the ESU dispatcher support system and have the possibility of changing without changing the ESU software and the dispatcher support system software) a sound and light alarm should be formed.An alarm is generated for each pressure measurement point, the transmission of values from which is provided;

- Performs automatic control of compliance with the calculated and actual values of pressure (pressure). In case of a deviation of the actual pressure value of the calculated (by the amount of reduction ^* 0.5 kgf / cm ² or more or an increase in the amount of 2.0 kgf / cm2 or more in accordance with the OP-03.100.50-KTN-093-08) a protection signal is generated “Discrepancy between the calculated and actual values of pressure (pressure)”;

- Performs graphical construction of lines of calculated and actual pressure (pressure);

- provides in real time the identification of facts of leakage of the pipeline with the determination of the magnitude, place and time of occurrence of leakage at all modes of operation of the pipeline (including in transition modes and in the mode of stopped pumping), including sections with incomplete filling of the pipeline section with oil;

- predicts the movement of SOD and Cayman sealants with the issuance of estimated values of the arrival time at the SOD checkpoint and the passage of the linear gate valve assemblies;

- predicts the time of emptying / filling of tanks, taking into account the current pumping mode;

- performs identification and automatic control of the actual pressure characteristics of pumping units;

- Performs identification and automatic control of hydraulic resistances and effective diameters of the pipeline with the issuance of a warning signal when deviations from the previously recorded value exceed the specified value;

- automatically detects the presence of flow sections with a pressureless flow between adjacent pumping stations;

- automatically controls the stationarity of the pumping mode with the issuance of a warning signal in case of its achievement or termination.

The actual hydro-gradient line is built on the basis of current pressure data on the linear nodes of the pipeline in the form of a broken line, the nodes of which display the pressure values at specified points (in linear nodes of the pipeline).

The following possible technological reasons for the change in pressure in the BCTO-II TS MN are taken into account by the mathematical model and do not exceed the deviation of the actual values from the calculated values more than the values indicated above:

a) during the transition from oil supply to the reception of PNS only from the RP (for a particular set of pumping collectors) to oil supply to the reception of PNS from the RP, but with connected route backwater from the previous technological section;

b) when switching from one tank connected to an oil pumping unit to another tank with an absolute bottom mark and level of overflow different from the first;

c) when supplying oil to the reception of PNS from the RP with connected track backwater from the previous technological section (during the transition from the normal operating mode of the LACT meter to the mode of monitoring metrological characteristics, when calibrating the flow meters at different flows or when the LACT meter is turned off; depending on the number and type (turbine, ultrasonic, chamber, mass meter) flowmeters included as workers; when changing the differential pressure on the filter unit SIKN and pressure drops on the filters for fine cleaning the measuring lines; with temporary activation of PNA for testing);

d) when changing the differential pressure on the individual filter gratings PNA;

d) when changing the current state of the fluid coupling MNA;

e) when the pressure characteristics of the MNA or PNA change during operation;

g) in the presence of pumping oil from technological tanks, including emergency dumping of fuel pumps, pumps controlled by a telemechanics system;

h) when changing the pressure drop across the NPS strainer filters;

i) when changing the current state of the pressure control unit "to yourself";

j) when the state of the nodes with safety valves of the oil pump station changes (there is no oil discharge / there is oil discharge, including unauthorized one);

k) when changing the volume of travel selections and paging;

m) during the sequential pumping of several batches of oil with significantly different physical properties;

m) when oil arrives at points of pumping points with rheological properties that differ from that pumped for possible technological reasons, pressure changes in the BCTO-II TS in stationary modes may not be taken into account by the mathematical model and may lead to exceeding the deviation of the actual values from the calculated values by more the values indicated above: filling SOD chambers; the process of starting and receiving SOD; authorized selection of oil for own needs; in the presence of pumping oil from technological tanks by pumps not controlled by the telemechanics system.

These situations should be reflected in the technological operating procedures of the operating organization, in which the composition and sequence of actions of the operating and dispatching personnel in each specific situation should be given in order to exclude the stop of the technological section by the protection of the technological section.

The hydraulic resistance and effective diameter should be calculated for each section of the MN between two adjacent gearboxes. A graphical display of the time dependencies of the calculated and actual values of pressures (pressure) should be carried out using SDKU.

The dispatcher support system for the JMA function should function as follows:

- the fault-tolerant server of the mathematical model processes the operational data from the input-output server and directly from the controllers of the SDA, as well as data about the route profile, equipment characteristics, and operating modes;

- with a given level of reliability, for a specified period of time, determine the occurrence of an oil leak from the oil pipeline, the magnitude and coordinate of the leak in accordance with the requirements of RD-13.320.00-KTN-223-09;

- if a leak is detected, the mathematical model server notifies the dispatcher support automated workstation about this and transmits a leak message (magnitude, detection time (Moscow) and coordinate) to the I / O server;

- generate a signal to automatically stop the technological section of the pipeline when a leak is detected with a value exceeding the error in determining the balance of the amount of oil in the diagnosed section of oil pipeline (the error is determined according to RD-13.320.00-KTN-223-09).

The training complex is designed to train and control the skills of the dispatching personnel of the traffic police, traffic police; to check the possibility of using new technological modes developed by the technological modes service of the operating MN organization; as well as to check the software of the I / O server, algorithm controllers, dispatcher workstation, if necessary, to make adjustments to them.
