Abstract

The invention belongs to the technical field of electric systems, and relates to an intelligent device for simulating transformer substation primary equipment behavior. The intelligent device comprises an information processing module, a function switching module, a primary equipment interface module, an analogue simulation module and a test control switch. According to the intelligent device, the state of primary equipment can be simulated, and switching off and switching on of a breaker, operations of a disconnecting switch ( and an earthing knife-switch), analog control of transformer on-load voltage regulation and primary equipment state correctness testing can be finished in a secondary system integrator. The problem that a control loop of a traditional intelligent device needs to be tested on the spot is solved, and a necessary condition is created for achieving the testing of a secondary system plant preset mode.

Description

technical field [0001] The present invention relates to a simulation system in the field of power system technology, in particular to an intelligent device for simulating the operation behavior of primary equipment (circuit breaker, isolating switch, grounding switch, transformer tap adjustment). Background technique [0002] The substation's circuit for operating and controlling electrical primary equipment (such as transformers, circuit breakers, disconnectors, grounding switches, hereinafter referred to as primary equipment) is an important part of substation control. Under the situation that substation construction requires the factory preset mode, smart devices (such as relay protection, operation boxes, smart terminals, smart components, hereinafter referred to as smart devices) that are widely used at this stage are used as control devices for primary equipment. The function of simulating the action behavior of a device obviously cannot meet the requirements of the fa...
