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.
