摘要
基于对小电流系统单相接地故障特征的分析,采用模糊集理论计算各线路对故障的可信度。据此设计以微型机为平台的小电流系统接地故障选择装置,从而保证装置对参数变化具有鲁棒性。
Through the analysis about the features of the small current grounding system,the degrees which the lines have fault can be calculated with using fuzzy set,and the principle of earth-fault selection device based on the PC are designed from it.This method can en-sure the device has robustness to the parameter's variety.
