摘　　要：随着电力系统的发展和应用,多回线路同杆并架现象已经变得非常普遍,线路间存在的互感对电路网络的分析和计算有着较大的影响。采用“相分量法”对互感线路进行分析,建立无互感线路等值模型,利用节点电压法求解电压或电流值。算例用两种方法对含互感支路的电路进行了计算,两种计算方法结果一致,验证了“相分量法”的有效性和正确性。算例显示,采用相分量法使计算量减少,编程难度降低,是一种灵活、方便、快捷的计算方法。With the development and application of power system,the phenomenon of multi-circuit lines on the same pole has become very common.The mutual inductance between lines has a great impact on the analysis and calculation of circuit network.Establishing the equivalent model of the non-transformer line,and using the node voltage method to solve the voltage or current value,the"phase component method"is used to analyze the mutual inductance line.Two methods are used to calculate the circuit with mutual inductance branch.The results of the two methods are consistent,which verifies the validity and correctness of the"phase component method".The calculation example shows that the use of phase component method reduces the amount of calculation and the difficulty of programming.It is a flexible,convenient and fast calculation method.
