基于零损耗深度限流装置的电网短路电流建模与仿真研究
Modeling and Simulation of Short-circuit Current of Power Grid Based on Deep Current Limiter with Zero-loss
摘要
Abstract
For modem power system,the increasing system capacity,the interconnection of regional large power grids,and the rising line load have made the short-circuit current far surpass the current breaking capacity of circuit breakers.So excessive short-circuit current governance has become an urgent topic for power grid companies.In this paper,the principle and working logic of the deep limiting device of current based on the zero-loss deep current limiting principle are analyzed,the zero-loss deep current limiter is introduced,and an actual 330 kV power grid is simulated and calculated.Results show that the zero-loss deep current limiting device can temporarily isolate short-circuit fault of the power grid,and significantly reduce short-circuit current.关键词
