The Electromechanical Transient Simulation Study of the Short Current Current-Limiter

Abstract:

With the expansion of the grid scale, the level of short-circuit current is significantly increased, we propose more stringent requirements to the grid. Limiting the short-circuit current is a problem to be solved.This paper used PSS/E to build the electromechanical transient simulation models of the SCCL device. We tested and checked the models by the system of IEEE 9 nodes 3 machines and concluded: In the current limiter parameters, the larger the inductor is,the better the effect of limiting current is. In the same resistance situation,the larger the inductance is, the better the effect of limiting current is, the smaller the short-circuit current value is.
