Description

Control method, system, computer-readable storage medium and computing device for realizing sole remote control right of smart substation

Technical Field

The present invention relates to a control method and system, a computer-readable storage medium and a computing device for realizing the unique remote control right of an intelligent substation, and belongs to the technical field of power system automation.

Background technique

Remote control operation is the core function of power grid production and operation, and is the basis for ensuring the safety of personnel, power grids and equipment. Substations facing multi-service master stations for power grid dispatching and centralized monitoring of power grid equipment need to establish a safe and reliable remote control technology system. Research on the unique technical method of remote control rights for smart substations is of great significance to ensure the safe and stable operation of large power grids. If multiple switchgear (including circuit breakers and knife switches) of the substation are operated at the same time, unpredictable power grid failures may occur due to overlapping switch contacts. Therefore, the dispatching automation regulations require that only one remote control operation task should be supported at the same time, and the substation monitoring system should respond to failures for other operation instructions at the same time, which involves the issue of unique remote control rights. At present, there is no unified technical route for the unique remote control rights. The monitoring systems of various substations can only rely on the service bus to exchange remote control rights to achieve remote control interlocking at the station control level. There is a blind spot for remote control rights, and there is no solution for the remote control rights of the interval layer.

When other bay layer devices receive the information that the bay layer remote control selection state is TRUE, the remote control rights of other bay layer devices are locked;

When the station control layer equipment receives the information that the bay layer remote control selection state is TRUE, the synthesized whole station remote control selection state is TRUE, and the remote control right of the station control layer equipment is locked;

The whole-station remote control selection status is sent to the remote master station as TRUE, and the remote control right of the remote master station is controlled to lock the remote control right based on the whole-station remote control status.

Furthermore, the default values of the bay layer remote control selection state and the whole station remote control selection state are FALSE, and when the bay layer device, the station control layer device and the remote master station do not receive a TRUE command, the remote control right is opened.

Furthermore, the condition for the bay layer remote control selection state stSeld to change from TRUE to FASLE is when any one of remote control success, remote control failure and remote control timeout occurs.

Furthermore, the information transmitted by the station control layer network includes MMS messages and GOOSE messages, wherein the MMS messages communicate with the station control layer devices, and the GOOSE messages communicate with other bay layer devices.

Furthermore, the default values of the bay layer remote control selection state and the whole station remote control selection state are FALSE, and when the bay layer device, the station control layer device and the remote master station do not receive a TRUE command, the remote control right is opened.

Furthermore, the acquisition module is used to

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

As shown in FIG1 , a control method for realizing the sole remote control right of a smart substation includes:

Obtain the remote control selection operation information monitored by the bay layer device, determine the bay layer remote control selection state, if the bay layer remote control selection state is FALSE, continue to monitor the remote control selection operation information; if the bay layer remote control selection state is TRUE, transmit the bay layer remote control selection state to other bay layer devices and station control layer devices through the station control layer network; the FALSE indicates that the remote control preset command has not been received, and the TRUE indicates that the remote control preset command has been received;

When other bay layer devices receive the information that the bay layer remote control selection state is TRUE, the remote control rights of other bay layer devices are locked;

When the station control layer equipment receives the information that the interval layer remote control selection status is TRUE, the synthesized remote control selection status of the entire station is TRUE, and the remote control right of the station control layer equipment is locked; the remote control selection status of the entire station is sent to the remote master station as TRUE, and the remote control right of the remote master station is controlled to lock the remote control right based on the remote control status of the entire station.

As shown in Figure 2, the remote control rights include the interval layer remote control rights, the station control layer remote control rights and the remote master station remote control rights. The interval layer remote control rights model the remote control selection state stSeld through the measurement and control device and monitor the remote control operation in real time, and transmit the remote control selection state to other measurement and control devices and station control layer equipment through the station control layer network. The interval layer remote control rights make remote control right judgments based on the remote control selection state, and the station control layer remote control rights make remote control right judgments based on the remote control selection state synthesized by the whole station remote control state YKSeld. The station control layer also sends the whole station remote control state to the remote master station. The remote master station remote control rights make remote control right judgments based on the whole station remote control state, thereby realizing the uniqueness of the remote control rights of the smart substation.

The remote control selection state stSeld of the measurement and control device is modeled based on IEC 61850, and stSeld is a remote control object data attribute.

The monitoring and control device monitors the remote control operation to feedback the remote control commands of the station control layer and the bay layer. The default value of the remote control selection state stSeld is FALSE. When a remote control preset command is received, the remote control selection state stSeld value is TRUE.

The condition for the remote control selection state stSeld of the measurement and control device to change from TRUE to FASLE is any one of the situations when the remote control succeeds, fails, or times out.

The station control layer network transmission information includes MMS messages and GOOSE messages, wherein the MMS messages communicate with the station control layer equipment, and the GOOSE messages communicate with other devices in the bay layer.

The bay layer remote control selection state is sent to other bay layer devices via GOOSE multicast. Other bay layer devices will block the remote control right of this bay as long as they receive the remote control selection state stSeld as TURE, otherwise they will open the remote control right of this bay.

The default value of the station control layer full station remote control state YKSeld is FALSE, and the synthesis logic is the bay layer remote control selection state stSeld or logic, that is, as long as the received remote control selection state stSeld is TURE, the station remote control state YKSeld is TURE, otherwise it is FALSE.

When the station-wide remote control status YKSeld of the station control layer is TRUE, the station-wide remote control right is locked, otherwise the station-wide remote control right is unlocked.

The whole station remote control status YKSeld is sent to the remote master station through the data communication gateway. The remote master station remote control right is judged according to the whole station remote control status YKSeld. When the whole station remote control status YKSeld is TRUE, the substation remote control right is locked, otherwise the substation remote control right is opened.

The bay layer remote control right, station control layer remote control right and remote master station remote control right are independent of each other, that is, they are independent at the judgment module level, and the failure of the remote control right of any layer does not affect the remote control right judgment logic of other layers.

As shown in Figure 3, the interlayer corresponds to the measurement and control device; the station control layer corresponds to the monitoring host and gateway machine; the remote master station corresponds to the dispatching system and centralized control system.

The present invention also provides a control system for realizing the sole remote control right of the intelligent substation, including:

An acquisition module is used to acquire the remote control selection operation information monitored by the bay layer device and determine the bay layer remote control selection state;

The judgment module is used to judge that if the bay layer remote control selection state is FALSE, then continue to monitor the remote control selection operation information; if the bay layer remote control selection state is TRUE, then transmit the bay layer remote control selection state to other bay layer devices and station control layer devices through the station control layer network; the FALSE indicates that the remote control preset command has not been received, and the TRUE indicates that the remote control preset command has been received;

The processing module is used to control the remote control rights of other interval layer devices to be locked when other interval layer devices receive the information that the interval layer remote control selection status is TRUE; when the station control layer device receives the information that the interval layer remote control selection status is TRUE, the whole station remote control selection status is synthesized as TRUE, and the remote control rights of the station control layer devices are locked; the whole station remote control selection status TRUE is sent to the remote master station, and the remote control rights of the remote master station are controlled to be locked based on the whole station remote control status.

The default values of the bay layer remote control selection state and the whole station remote control selection state are FALSE, and when the bay layer equipment, the station control layer equipment and the remote master station do not receive the TRUE command, the remote control right is open.

The acquisition module is used to

The command information of whether the bay layer equipment is remotely controlled is collected through the measurement and control device and modeled based on IEC61850 to determine the bay layer remote control selection state stSeld.

The processing module is used to
