Description

Automatic recovery guide system for load dispatching sub-center}

The present invention relates to an automated recovery guide system for a power supply branch, and more particularly, to an automated recovery guide system that provides failure determination and failure recovery procedures for substations under multiple jurisdictions on a power supply branch, communication from a SCADA operating device It is linked through, and by detecting the substation's failure situation and event for the unmanned substation under jurisdiction, it automatically determines the failure, infers the list of emergency recovery procedures, and presents it to the operator, so that the operator can perform actual recovery.

If a failure occurs due to various factors during the operation of a 154kV (or 345kV) substation, the substation worker must promptly recognize and judge the failure and then perform a recovery operation in accordance with the KEPCO standard recovery procedure (SOP). Failures must be analyzed and repaired within a short time after a failure occurs, and they are subject to strict management to the extent that a detailed report on the occurrence of failures is required to be submitted.

Currently, the response procedure for the occurrence of a 154kV (or 345kV) substation failure is “Failure Occurrence → Fault Recognition by Worker → Fault Judgment (Judged by Personal Experience/Capacity) → Fault Recovery (Recovery by Personal Experience/Capacity) → Report to Superior (Department) Fault recovery proceeds in the order of “.

Workers familiarize themselves with the KEPCO Standard Recovery Procedure (SOP), and in the event of an actual failure, they determine the failure and perform recovery operations based on the contents of the standard recovery procedure. The situation is being restored by personal experience and ability.

Since the ripple effect due to power outage is severe when a breakdown occurs at a substation, workers are instructed to familiarize themselves with KEPCO's standard recovery procedure so that the stability of power supply can be secured through fast and accurate substation breakdown recovery operation. Since <A> describes only limited failures under the standard substation topology and facility operation conditions, even experienced workers can be perplexed when failures occur under various topologies and facility operation conditions encountered in the actual substation operation process. And it can cause difficulties in accurate recovery operation.

Therefore, as currently, restoration operations are carried out based on individual experience and ability, and human errors due to momentary errors in judgment frequently cause secondary power outages and breakdowns. The social and economic costs of power outages due to occurrence are significant and are increasing day by day.

Nine main transformer NGR disconnection failure information is generated, and the failure type determination unit further receives gas pressure information of each of a plurality of gas insulated switches (GIS) of the substation, and further inputs the input gas pressure information to the plurality of logic circuits. and the recovery procedure output unit determines the type of failure to output substation recovery procedure information to which the location information of the gas insulated switch having gas pressure information out of the reference gas pressure range among the gas pressure information of each of the plurality of gas insulated switchgears is applied. The unit further receives on/off state information of each of the plurality of disconnectors of the substation, further applies the input on/off state information to the plurality of logic circuits, and the recovery procedure output unit receives on/off state information of each of the plurality of disconnectors of the substation.

And, according to the substation recovery procedure information output when operating in the automatic recovery mode, it is characterized in that the monitoring control and data acquisition (SCADA) system is output to a remote terminal unit (RTU) to control the substation. .

Like the current digital substation operation system, the monitoring and control systems of power facilities are being advanced and automated. There is a need for an automated system that can handle this.

The automated recovery guide system according to the present invention is located in a manned dispatch branch of KEPCO and exists on an equivalent network linked with a SCADA (SCADA) operating system. The automated recovery guide system is linked through communication from the SCADA operating device, and synchronizes or identifies the status by receiving the status of multiple substations in the lower jurisdiction through SCADA. The guide system detects substation fault conditions and events for unmanned substations under jurisdiction, automatically determines faults, infers a list of emergency recovery procedures, and presents them to the operator.

Through this, by providing a UI that can be manipulated so that the operator can perform actual recovery, 　 UI and guidance are provided so that 　 　 operator's 　 recovery is guided, and the most efficient failure recovery procedure is deduced. It is a guide system that enables the operator to quickly and safely perform the switch operation procedure corresponding to the actual recovery step by step.

The automated recovery guide system is a system suitable for KEPCO's dispatch branch office, and is an intelligent device that specifically implements KEPCO's standard recovery procedures. It can be implemented in conjunction with a server and a client equipped with a GUI.

KEPCO's standardized recovery procedure SOP describes only the most representative failure cases, so it cannot contain all of the various variations or exceptions. Therefore, actual individual substation failure situations can be wider and more diverse than standard recovery procedures.

In addition, it is known that recently, KEPCO is conducting a pre-stage review before presenting an amendment to the standard recovery procedure SOP. Therefore, the automated recovery guide system generalizes long-term failure cases and recovery, and recovers safely by making the most predictable and correct judgment through statistical probabilistic judgment and recovery process inference using the traditional expert system and the latest deep learning technology. We can provide information, procedures, and guidance to proceed. The guide system refers to substation status data, measurement data, and knowledge base for referring to past cases, and is a procedure for determining and recovering failures that are generally expected to be reasonable measures that KEPCO's experienced substation operators can derive. It can be implemented to derive and present.

As a configuration of the present invention for this purpose, a guide server including a communication unit capable of receiving data by determining a communication interface that can be provided by the branch SCADA, a failure event occurring in a plurality of lower substations, or a failure related to a plurality of constantly occurring events. Pre-processing unit that transmits only meaningful information for determining and recovering subsequent failures by multi-step filtering through pre-processing of events that do not have any It can be defined as including a database that processes data for each failure case and builds a table based on an information database as a Knowledge-Base and includes a database that optimizes tuning through testing, evaluation, and training through a guide system.

At this time, the guide server may receive the current values of the state data database and the measurement monitoring database of the lower substation associated with the SCADA system of the power supply branch, and store them in a synchronized database.

In addition, the guide server receives the table and point information of the status and measurement database of the lower substation associated with the SCADA operating system during the initialization process of the database, and after initial synchronization, intelligently compares whether the number of items and item names match to check for discrepancies can do.

In addition, the guide server may perform state synchronization of the state of the lower substation within a limited time of 2 minutes resolution.

Hereinafter, embodiments of the present invention will be described in detail.

according to the present invention The guide system includes a guide system server including a communication unit, and the communication unit can receive data by determining a communication interface that can be provided by the branch SCADA. Communication rules and data packet frames follow the contents of each operation. SCADA of the dispatch branch may drive a process or agent that passes information on a request according to the interlocking method of the guide system. Such a request may include the allocation number and point name of all points of equipment for each lower substation, operation status, and the like. In addition, it can be an event of change in operating status of switch information such as circuit breakers/relays/disconnectors. It may also be measurement value change information. It has channel response capability for periodic state synchronization and event information reception in case of failure.

The pre-processing unit multi-steps filtering through a pre-processing process for events unrelated to failures among failure events occurring at multiple substations simultaneously or multiple constantly occurring events, and only information meaningful for determining and recovering subsequent failures is transmitted. This optimizes the time factor of information processing and eliminates confusion in advance.

At this time, the automated recovery guide server receives the current values of the state data database and measurement monitoring database of the lower substation associated with the SCADA system of the power supply branch, and stores them in a synchronized database. The automated recovery guide server receives the table and point information of the substation status and measurement database linked to the SCADA operating system during the initialization process of the database, and after initial synchronization, intelligently compares whether the number of items and item names match to check for discrepancies. .

In general, the switch state of a substation and the measured values for current and voltage values do not change in seconds and maintain the same state continuously. However, the automated recovery guide system keeps the real-time synchronization time as low as possible to improve the efficiency of the response before and after the failure. However, since other processing time is required after real-time assimilation, synchronization is performed regularly within the optimal balance limit considering the number of substations and minimization of communication traffic.

It is desirable for the automated recovery guide server to perform state synchronization of the number of N substations (usually around 10) substations within a limited time of 2 minutes and a resolution of 2 minutes.

It is desirable for the automated recovery guide server to synchronize the measured values of substation N of the lower substation within a limited time of 20 seconds.

Synchronization time resolution and precision of measurement values can be adjusted according to the bandwidth of the communication channel according to the number of substations.

In the virtual substation layer or virtual substation layer (hereafter referred to as the virtual substation layer), all subordinate substations in connection are commonized and mapped as one failure and recovery type management model, so that the database is relocated in the same order of evaluation items with the same function. map the points

The virtual point number in the virtual substation layer must be able to accommodate both the digital substation and the old RTU substation, and the order of assignment of the virtual point number is centered on the main transformer T/L - 154kV BUS - main transformer - 23kV BUS - D/L It consists of points for key operation and failure management of the entire substation in bank order.

This virtual substation measurement state management, which unifies the failure evaluation method and procedure, is implemented with the same virtual point number and name + state management function mapping, using the virtual file system of Linux as a similar reference model.

When a substation is changed or newly expanded, it is structured so that it can be easily expanded like Plug-in & Play. The status of each substation associated with the actual power supply branch is relocated to the shared memory and used for memory-based rapid calculation.

In addition to the representative failures advocated by KEPCO's standard recovery procedures, the database contains examples of failures, substation operation status, failure judgment status, and actual results of failure recovery in preparation for variously changing future substation situations and unexpected failures. As a knowledge-base that is recorded as a whole, data is processed for each failure case to build a table based on the information database, and tuning is optimized through testing, evaluation, and training through the guide system.

Since the cases of breakdowns are internal data of KEPCO, a construction organization, and only a handful for one year, it is not possible to secure a large amount of useful statistical information. Therefore, for accurate recovery, it is necessary to build a database of significant quantities (data size) related to failure occurrence, judgment, and recovery by valid ground data.

Therefore, there is a virtual simulated failure generator and a failure simulator that generates simulated failure situations that occur through this system. It is developed together with the automated recovery guide system.

The failure information database records the occurrence event and measurement values at the time of virtual simulated failure, the failure determination result through the inferred virtual substation hierarchy, and the inference result of the optimal recovery procedure to provide improved statistical data that can be used for the next random failure. is updated

The failure information database records the results of simulated failures and restorations and preserves the possibility of recovery by experts or based on standard recovery procedures (SOPs) as a single set of data (SET) in the database. The failure information database can also update failure information during actual operation through feedback.

All columns and information of the failure information database can be used partially or entirely depending on the failure situation.

The failure information database becomes a system base that can universally respond to failures and judgments other than KEPCO's standard recovery procedure (SOP).

In order to improve the performance of the automatic recovery guide system, including virtually tested failures, failure case cases are continuously optimized on a scale of 100 to 1000 or more.

A substation fault determination rule is used as an inference engine. The failure judgment rule is determined in advance as a rule with the information value of the GIS GAS point, circuit breaker (CB), disconnector (DS), relay information, and current state of the measured value as logical conditions according to the type of failure. The size of domain space that can be combined with a set of faulty switches (CB, DS, Relay) is defined.

Failure judgment rules are recorded in a replaceable database, and the judgment inference engine reads from the database corresponding to these code books and initializes them in the server system. Compare

The failure determination rule is based on the virtual substation layer and is designed considering both the cases of the digital substation (SA) and the existing substation (RTU). The size of the rule can be increased by checking the non-conflicting conditions of the failure determination rule.

Decision tree algorithms can be used to determine failures. Breadth-first searches as many as the total number of rules classified based on the Decision Tree in the shortest time.

Failure judgment is determined by the failure type with the highest matching probability in the basic failure determination rules written up to now. If there is no rule that matches all the rules registered in the failure determination rule, candidate failures are recommended using the similar failure recommendation algorithm. The failure determination algorithm may refer to information from a database modeling substation equipment and topology for determination. The fault determination algorithm can refer to the measured values of the substation (T/L line, 154kV BUS, M.Tr 1st, 2nd, 23k BUS, main voltage and current measured values on the D/L line).

The failure determination engine finds and determines failures, and delivers a series of data related to the determination to the recovery engine for recovery procedures. Failure determination and operation information of major equipment are transmitted to the engine that infers the recovery procedure as a set of parameters.

In the case of undetermined failures where complete information is not given, it is necessary to classify and classify the most meaningful failure types through existing failure cases and current input information. In order to automate this similarity, a separate normalized database can be created and similar failure and correlation analysis can be performed. In order to recommend a similar failure, the following processing is required. Establish a failure knowledge base database that normalizes cases in terms of substation failure and recovery. The correlation coefficient is estimated through analysis in the standardized and normalized knowledge base database, and the similarity of the failure and the proximity to the corresponding failure are output as probability and correlation coefficient. The distance of the sample data is calculated based on the N-dimensional Euclidean distance. The failure knowledge base data is standardized by dividing it by the standard deviation in terms of data variance. The data of the failure knowledge base is normalized and the distribution is stored within a certain range.

The failure recovery inference engine receives the parameter for the type of failure from the failure determination engine, searches for and infers a failure recovery procedure to connect a new supply to the blocked load, and makes normal power supply, and outputs a procedure document. The failover inference engine considers the topology of substations that were in normal operation. The failover inference engine considers the topology of the substation after a failure. The fault recovery inference engine refers to the measured values of the analog primary and secondary side voltage and current of the main transformer M.Tr in the substation. The failure recovery inference engine considers the load supply source and the priority of each load for connection of the interrupted load. The fault recovery inference engine evaluates the supply capacity of the main transformer M.Tr as the entire substation and infers the available supply capacity. The failure recovery reasoning engine determines the possibility and method of load switching by checking whether the available supply capacity matches the required amount of load. The failover reasoning engine estimates a new supply path by manipulating the CB and DS switches for a new supply of the cut-off load. The procedure and sequence of switch operation must fit the protected interlock relationship in the substation. To this end, an interlock setting and a check for violations must be performed. Load switching is determined by comparing a method having the shortest switch operation path among pressurizable switching methods. For load switching, methods such as conversion using adjacent M.Tr, conversion between 154k-BUS, conversion between 23kV-BUS, conversion using BUS-TIE, and conversion using SECTION are used. The possibility of success for load switching is made up of a routine that evaluates the available M.Tr and the ability to supply available power compared to the load being cut off. The entire recovery procedure is sent to the client system by proposing the optimal candidate.

In summary, the present invention is linked through communication from the SCADA operating device, detects substation failure situations and events for unmanned substations under jurisdiction, automatically determines failure, and infers an emergency recovery procedure list and presents it to the operator Provides a UI that can be manipulated so that the operator can perform actual recovery, guides the operator's recovery by providing UI and guidance so that the operator can perform emergency recovery from an urgent confusion, and infers the most efficient recovery procedure. In this case, the operator can quickly and safely perform the switch operation procedure corresponding to the actual recovery step by step.

The embodiments of the present invention described above are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
