Remote verification system and method for telecontrol forwarding data of transformer substation

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.

Description

technical field [0001] The invention relates to the technical field of substation data verification, in particular to a remote verification system and method for substation remote forwarding data. Background technique [0002] At present, in the field of power system substation automation, the verification of forwarding table data still relies on 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 the I and II areas 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 co...

[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
