应用运算曲线求取短路电流时电源计算电抗的通用算法

运算曲线是求解任意时刻短路电流的有效工具。查运算曲线首先要算出每个电源对短路点的计算电抗。然而，目前对复杂网络中电源计算电抗的计算模型及方法的研究尚存不足，没有提出普遍适用的计算公式，更没有给出适合计算机算法的数学模型。

Common Algorithm for Computing Power Source Calculating Reactance in Applying Operational Curve to Solve Fault Current

Operational curve is an effective tool used to calculate fault current at anytime.The calculating reactance between power source node and fault node must be computed first before checking operational curve.But the study on the method and model for computing power source calculating reactance of complex network is not enough.Neither the general formula nor the mathematics model suitable for computer has been put forward.Applying basic electric theory and method it analyses in detail the various power source situation in fault network and gives out a series of formulas through strict theoretical inference,with which the calculating reactance between finite or infinite power source node and fault node can be computed.These formulas are simple,clear,strong in general use and convenient for computer.This will provides the model and algorithm for the computerization of operational curve method to solve fault current.Thus it has practical significance and high application value.
