摘　　要：小电流接地系统发生单相接地故障时,系统电气量与接地故障线路(或母线)存在映射关系。利用基于遗传算法的BP网络来描述这种映射关系,实现确定接地故障线路(或母线)。测试结果表明,方法快速、准确,具有一定的实用价值。Based on the high non-liner map relation of Ground fault line or Bus with the electric character such as Zero-Sequency voltage and current and so on in Peterson-coil-grounding system(PCGS), A novel approaches that BP networks with the characteristic of simulation non-linear fuction on the basis of genetic algorithm is applied to ground fault line dectection in PCGS is put formard, the results of simulation show the method is nicely and credibility and can be used in practice.
