| 摘 要： | 新型高压电网单相接地漏电故障选线方法采用电流谐波故障诊断法、零序有功功率法和暂态零序电流互积求和法设定故障测度隶属函数和权重系数隶属函数;采用模糊理论将3种方法各自的隶属函数和权重系数隶属函数进行融合,计算出多判据选线方法下的线路故障测度,从而可判断出单相接地漏电故障线路。Matlab/Simulink仿真结果验证了该方法的正确性。

| Abstract: | A new type of line selection method of single-phase grounding leakage fault of coal mine high-voltage grid uses fault diagnosis method of current harmonic,zero-sequence active power method and transient zero-sequence current mutual product sum method to set membership functions of fault measures and weight coefficient,uses fuzzy theory to fusion the above functions of the three methods to calculate fault measures of line under line selection method with multi criteria,so as to judge line of single-phase grounding leakage fault.The Matlab/Simulink simulation result validates correctness of the line selection method. |
