摘要
对当前配电网难以解决的接地故障定位问题提出新的解决办法———传递函数法。阐述了应用于配电线路故障定位的传递函数理论 ,给出了传递函数的定义 ,并详细推导了三相配电线路接地故障定位的传递函数表达式 ,通过对理论公式的数值计算 ,证实了配电网接地故障定位的传递函数法是切实可行的。
Transfer function algorithm for locating line to ground fault in power distribution lines is assumed in this paper. The system analysis method of transfer function is introduced to power distribution lines and the definition of transfer function for fault location is integrally propounded. The formulas of transfer function in three phase distribution lines with ground fault are deduced in detail. Numerical analysis to the formulas verified that the algorithm is effective to fault location for power distribution networks.
