A new method based upon Refined Genetic Algorithm (RGA), which global optimum is easily converged with, for the fault section estimation problem is presented. There are some new operators in RGA and basic operations of RGA are different from those of SGA.

• 本文研究了RGA在电力系统故障诊断中的应用,这种方法可以有效地求得全局最优解,与SGA相比RGA的遗传算子中包括了一些新的算子,基本算子的实现方式也不一样。
