摘要

采用串联谐振型故障限流器是解决电网短路电流超标问题的一种新技术手段。介绍了谐振型故障限流器的基本原理,用PSCAD软件建立模型对串联谐振型故障限流器在电网中的应用进行了仿真并对其拓扑结构进行了改进,仿真结果表明串联谐振型故障限流器能有效地限制短路电流水平。%Adopting the series resonant type fault current limiter is a new kind of technology means to solve the problem of power grid’s short-circuit current over standard. Introduction was made to the basic principle of resonant type fault current limiter. Simulation was carried out by using PSCAD software to construct a model for application of series resonant type fault current limiter in power grid, its topology structure improved. The simulation result shows that the series resonant type fault current limiter can effectively limit short-circuit current level.
