Method and system for automatically generating anti-sabotage, anti-blocking, water irrigation, breathing, fire burning logic rules of substation

Abstract

The invention discloses a method and a system for automatically generating anti-sabotage, anti-blocking, water irrigation, breathing, fire burning logic rules of a substation. The method comprises the steps of: analyzing a drawn primary equipment main wiring diagram into a plurality of ordered primary equipment objects; and automatically generating the anti-sabotage, anti-blocking, water irrigation, breathing, fire burning logic rules according to the preset generating rules determined by the anti-sabotage, anti-blocking, water irrigation, breathing, fire burning logic rules and the logic relationship among all the ordered primary equipment objects. In the technical scheme, the drawn primary equipment main wiring diagram is analyzed into the ordered primary equipment objects, therefore, the anti-sabotage, anti-blocking, water irrigation, breathing, fire burning logic rules can be automatically generated according to the logic relationship among all the ordered primary equipment objects and the preset generating rules determined by the anti-sabotage, anti-blocking, water irrigation, breathing, fire burning logic rules. The automatically generated anti-sabotage, anti-blocking, waterirrigation, breathing, fire burning logic rules are completely right in theory and can be applied to the substation so as to effectively improve the safety and the reliability of the substation.

Description

technical field [0001] The invention relates to the field of substation comprehensive automation systems, in particular to a self-generating method for substation five-defense logic rules and a self-generating system for substation five-defense logic rules. Background technique [0002] The "five defenses" of substations mainly refer to preventing accidental entry into live intervals, accidental closing of circuit breakers, closing of knife switches with loads, live ground knife (hanging ground wire) and ground knife (ground wire) closing switches. The five-prevention logic rules of the substation are related to the safety of primary equipment (equipment that directly produces, transmits, distributes and uses electric energy, called primary equipment) and maintenance personnel during the operation of the substation. ) important functions. In all existing substation automation systems, a five-defense logic system needs to be set up. The structure of the substation integrated...

[0005] Second: No matter which unit formulates the five-defense logic rule logic library, it is inevitable that there will be mistakes in the compilation of individual five-defense logic rules. Some will miss the logic of a bypass knife switch state, and some will miss It is due to human error and wrong writing. In the current engineering application, the five-defense logic rules are manually summarized by experienced technicians according to the operation rules. For some relatively simple substations, the workload is still enough. Expected, and tolerable, but for substations with complex wiring and large scale, the workload will be quite large, and the possibility of errors is also high

[0006] If this kind of wrong five-prevention logic rule is configured to the substation integrated self-system, it may form a safety hazard, which is undoubtedly the most serious for the highest requirement for the anti-misoperation of the substation—safety. In practical engineering applications Among them, errors caused by compilation "fatigue" caused by the large scale of the main wiring diagram are the main reasons for the compilation errors of the five-defense logic rules
