遗传算法在电力系统故障诊断中的应用。将电力系统线路故障区域内动作的保护分为三类：主保护，第一后备保护和第二后备保护。根据三种保护的动作原理并结合该算法诊断电力系统线路上发生故障的继电保护元件。-Genetic algorithms in power system fault diagnosis. Actions in the area of ​ ​ power system line fault protection is divided into three categories: primary protection, the first back-up protection, and a second back-up protection. In conjunction with the algorithm based on the operating principle of the three protection and diagnostic failure in the power system on the line relay protection elements.
