Problems solved by technology

[0002] At present, in the field of power system substation automation, the verification of forwarding table data is still in the manual point-to-point mode, and it is difficult to realize automatic verification. For substation maintenance and maintenance personnel, there is a lack of effective forwarding table data maintenance mode and practical The verification method cannot realize the consistency management and control of the forwarding table data of each substation at the dispatching master station, and even the consistency of the telecontrol forwarding table data in areas I and II of the substation is still in an unknown state
With the commissioning and upgrading of a large number of substations, there are problems such as heavy workload and poor consistency in the remote forwarding data of substations, which seriously affect the safe and stable operation of the power grid, and there are major security risks

Embodiment 1

[0052] A substation remote forwarding data remote verification system, including a substation, a dispatching master station, and an operation and maintenance center master station; the dispatching master station and the operation and maintenance center master station are connected and communicated through a service bus, and the dispatching master station and the operation and maintenance center master station The substations are respectively connected and communicated with the substation through the dispatching data network dispatching data network;

[0053] The dispatching master station includes the master station forwarding table data service module, the master station data identification module and the data verification module;

[0054] The main station of the operation and maintenance center includes a double telecontrol forwarding data checking module and a main substation forwarding data checking module;

[0055] The substation includes remote generators in Zone Ι and r...

Embodiment 2

[0067] A remote checking method for substation remote forwarding data based on the remote checking system for substation remote forwarding data, comprising:

[0068] S1, respectively assign unique identifiers as keywords to the forwarding table data of the master dispatching station and the substation, so that the keywords of the same data object in the forwarding table of the master dispatching station and the forwarding table of the substation correspond to each other;

[0069] S2, check the forwarding table data between the dispatching master station and the substation, including:

[0070] S21, the master dispatching station sends a verification request containing the keyword of the data object to the substation, the substation responds to the verification request and returns the point number of the data object corresponding to the keyword in the verification request to the master dispatching station, and the master dispatching station judges the data object returned by the ...

Embodiment 3

[0086] The deployment architecture of the substation telecontrol forwarding data remote verification system is as follows: figure 1 As shown, the dispatching master station and the operation and maintenance center are located at the master station side, the dispatching master station and the operation and maintenance center use the service bus for remote communication through the internal LAN, and the dispatching master station and the substation remote machine use high-performance GSP (General Service Protocol) for remote communication enables multi-vendor substations to adopt unified interaction rules to achieve standardized interconnection.

[0087] There are three modes for remote verification of substation telecontrol forwarding data. One is located at the dispatching main station to realize the forwarding data verification of the main and sub-stations; the other two are located at the main station of the operation and maintenance center to realize the forwarding data veri...

Abstract

The invention discloses a remote verification system and method for telecontrol forwarding data of a transformer substation. The system comprises a transformer substation, a dispatching master stationand an operation and maintenance center master station, wherein the dispatching master station is connected and communicated with the operation and maintenance center master station through a servicebus, and the dispatching master station and the operation and maintenance center master station are separately connected and communicated with the transformer substation through a high-performance general service protocol (GSP). According to the remote verification system and method disclosed by the invention, the following three modes of verification functions can be achieved: 1, the consistencyverification of master sub-station forwarding table data is directly implemented at the dispatching master station; 2, the operation and maintenance center master station separately performs interaction with the dispatching master station and sub-station at an operation and maintenance center at the master station side, and the consistency verification of the forwarding table data between the dispatching master station and the transformer substation is implemented; and 3, at the operation and maintenance center at the master station side, the consistency verification of all channel data and forwarding table data of different telecontrol equipment in areas I and II is implemented. According to the remote verification system and method, safe and stable operations of power grids can be reliably guaranteed through multiple remote verification.
