Research on 220kV Spare Power Automatic Switching Equipment Standardized Application of Local functions Based on Real-Time Simulation

Abstract

Currently, the power grid is carrying out the standardized design and application of 220kV spare power automatic switching equipment. It is more difficult to carry out the on-site standby automatic switching function test in the actual power grid. The power supply department urgently needs a simulation environment that can truly simulate the actual power grid to support the development of this functional test. Real-time simulation has the ability to carry out on-site automatic transfer function tests in terms of technical feasibility. To verify its effectiveness, this paper built a standardized closed-loop test system for 220kV spare power automatic switching equipment based on real-time simulation. A number of tests have been carried out for the automatic switch-on function of on-site equipment, and the device action events on the actual site have been inverted. The test results show that the established RTDS real-time simulation model has the ability to simulate the actual 220kV power grid. It has been verified that the action logic of the standby automatic input device in various modes meets the requirements of the standard specification, which strongly supports the standardized application of the 220kV spare power automatic switching equipment function of the power grid.
