Configuration method and system for anti-misoperation locking logic rule source end of intelligent substation

Abstract

The invention provides a configuration method and system for an anti-misoperation locking logic rule source end of an intelligent substation. The method comprises the steps of constructing an intelligent substation system configuration information model-based anti-misoperation locking logic rule source end information library, and correlation relationships and indexes of elements in the anti-misoperation locking logic rule source end information library; and according to characteristics of the elements in the anti-misoperation locking logic rule source end information library, automatically identifying an anti-misoperation device in the anti-misoperation locking logic rule source end information library, and according to the correlation relationships and the indexes of the elements, searching out primary and secondary device information participating in locking rule calculation of the anti-misoperation device. By processing visual rule files for generating anti-misoperation locking logic, engineers can intuitively and conveniently judge whether a locking logic result reflects an actual working condition of a device layer or not in real time, and a debugging progress of an automation project of the substation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of intelligent substation automation, and in particular relates to a method and a system for configuring a source end of an anti-misoperation blocking logic rule of an intelligent substation. Background technique [0002] Smart substations are an important part of smart grid construction. Up to now, more than 1,000 smart substations have been built and put into operation by State Grid Corporation of China. In order to prevent misoperation, the five-proof operation rules of substations are stipulated, that is, to prevent mis-opening and closing of circuit breakers, to prevent disconnection and closing of isolating switches with load, to prevent live hanging (closing) grounding wires (grounding switches), and to prevent carrying grounding wires ( Grounding switch) and circuit breaker (isolating switch) to prevent accidental entry of live electrical intervals. Five kinds of error prevention. [0003] The anti-...

Problems solved by technology

[0008] The anti-error locking logic of smart substation is an important guarantee for the safe and stable operation of smart substations. However, the existing anti-error locking logic project files are manually configured based on database information, which is laborious and prone to human configuration errors, resulting in hidden safety hazards in operation.

The source of each manufacturer's configuration is inconsistent, which leads to difficulties in the interaction between the various manufacturers of the anti-mistake logic of the on-site configuration. The five-proof interlocking logic description file saved in the project configuration adopts its own proprietary description method for each manufacturer, including logic equation expressions, binary, etc. Complicated semantics are difficult for non-professionals to understand, which is not conducive to the reading, viewing and debugging of the anti-mistake locking logic, which is inefficient, time-consuming and laborious
