چکیده مقاله:
In this paper, the effect of number and fault current limiter(FCL) location has been investigated inorder to have maximum reduction of short circuit current level in all buses in a real network. To do so,the faulty buses were identified in terms of short circuit current level by computing short circuits on thedesired network. Then, while the fault current limit was modeled, its optimal location and amount forthe greatest reduction in the fault current level of the whole critical buses was determined.Optimization computations have been done using the genetic algorithm and method of reducing thesearch space and all implementation stages of the proposed algorithm and reduction of search spacehas been conducted in DIgSILENT software using programming language DPL. The results indicatethe high efficiency of the proposed method in reducing the short circuit current level of faulty busesand simultaneous improving the power quality.
