Abstract

The invention provides a substation five-prevention verification method based on switching principle. The method comprises the following steps: S1) drawing a main wiring diagram of primary equipment of a substation; S2) carrying out model analysis on the main wiring diagram of the primary equipment to obtain an equipment model; S3) according to five-prevention rules, determining the switching principle of each type of operating equipment, and defining unlock state of condition equipment based on the switching principle; S4) when operating the operating equipment, searching in the equipment model to obtain the condition equipment; and S5) judging whether the real-time state of the condition equipment meets the unlock state, and if so, allowing operation, and if not, forbidding the operation. The method avoids manual work of defining logical conditions for each specific device in the substation and prevents the risk of making errors in manually defining the logical conditions.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a five-proof verification method for substations based on the switching principle. Background technique [0002] Five preventions usually refers to the abbreviation of five anti-mistake functions for high-voltage electrical equipment to ensure personal safety, and is one of the important measures for electric safety. The five preventions are to prevent mis-opening and closing of the circuit breaker; prevent the load from opening and closing the isolating switch; prevent the live wire from hanging (closing) the ground wire (ground switch); prevent the ground wire from being powered; [0003] Traditional substation five-prevention system customizes logical conditions for each device individually. When customizing logical conditions, manually select a number of related devices, and use the on-off status of each related device as the logical condition. When installing the five-p...
