摘要
华东500 kV电网短路电流超标问题甚为严重,超高压电网短路电流限制器利用依据电感电容串联谐振的原理,在系统短路时通过晶闸管迅速旁路电容器,使限制器呈现感性,达到对短路电流的抑制。以2010年作为超高压电网短路电流限制器的投产年,从短路电流抑制效果角度进行短路电流限制器示范工程选点方案的研究。
The short-circuit current problem is serious in East Chin Power Grid. As a solution, the short-circuit current limiter can quickly bypass its capacitor with the help of the thyristor and display inductive impedance during short-circuit faults, which can limit the short-circuit current. Since the short-circuit current limiter for EHV grids is expected to put into operation in 2010, the siting scheme for its demonstration project is studied from the point of view of its control effectiveness.
