摘　　要：对自动跟踪消弧线圈接地系统进行了仿真研究。结果表明:零序功率震荡和采样误差是造成零序有功功率选线方法不准的两个主要因素。为了减小这两个因素的影响,对零序有功功率选线方法的模型进行了改进,并利用MATLAB软件对改进模型进行了验证。The paper made simulation research on autotracking arc - suppression - coil - earth system. The results show that , oscillation of zero sequence power and sampling error is larger influence quantity which made fault lineselection based on zero sequence active power error. To decrease the influence , the paper made modification on the model of fault line selection based on zero sequence active power . Meantime with the help of MATLAB , we verifies the feasibility of the model .
