Embodiment Construction

[0025] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Device example:

[0027] The invention provides a main and auxiliary linkage device of a substation, which includes a main control system and an auxiliary control system. The main control system is used to send a linkage message of the measuring point to the auxiliary control system, the content of the linkage message includes: index number of the measuring point, attribute, value description and time stamp; the auxiliary control system is used to find the measuring point index number according to the index number of the measuring point in the message after receiving the linkage message Click the index number in the auxiliary control system to obtain the corresponding linkage strategy, send linkage commands to the corresponding auxiliary control subsystem according to the linkage strategy, and the received auxiliary control subsystem ...

Abstract

The invention provides a substation main and auxiliary linkage method and device. When a measuring point has a remote signaling displacement signal or a fault trip signal, a main control system sendsa linkage message of the measuring point to an auxiliary control system; the auxiliary control system finds the index number of the measuring point in the auxiliary control system according to the index number of the measuring point in the message, obtains a corresponding linkage strategy, and sends a linkage command to a corresponding auxiliary control subsystem according to the linkage strategy,and the linkage strategy is performed by the received auxiliary control subsystem. The linkage system has a simple structure, does not require additional equipment and reduces the cost, and during data linkage processing, the processing procedure is relatively simple. The operation and maintenance personnel in the station can monitor the displacement signal or fault trip signal of the main control system from a main control work station in a monitoring work station in the station and confirm the remote signaling displacement signal or fault trip signal of the main control system, so that information sharing and intelligent linkage between the main and auxiliary systems of the substation are enhanced, and great significance is achieved for improving the safety and reliability of substationoperation.

Description

technical field [0001] The invention belongs to the technical field of intelligent substations, and in particular relates to a main and auxiliary linkage method and device of a substation. Background technique [0002] In the smart substation system architecture, the main equipment monitoring system (referred to as the main control system) is located in the safety area II, and the auxiliary equipment monitoring system (referred to as the auxiliary control system) is located in the safety area III. There is a positive isolation device between the two areas to ensure the single data to transfer. Substation main equipment monitoring and various auxiliary equipment monitoring systems are independent, interfaces are scattered, equipment coverage is incomplete, information uploading is incomplete, main and auxiliary equipment information cannot be effectively shared, and substation operation and maintenance personnel lack effective monitoring methods for jurisdictional equipment. ...
