摘要
基于分解协调法，采用相序参数变换技术和补偿法，提出了一种无需形成故障后子系统群数学模型，能充分利用对称元件在对称分量坐标系中可解耦的特性，并行或串行快速计算三相参数对称或不对称电力系统任意复杂故障的新方法。这种方法不但能适应因故障造成的网络拓扑结构变化，而且取消了对故障类型和元件参数三相是否对称的限制，并进一步扩大了解题规模，提高了故障计算的速度和效率。
In this paper,a decomposition coordination method for fault calculations in a power system with symmetrical and/or asymmetrical components is presented.A fault is modeled as a modification to the network topology of original networks.Based on the decomposition coordination method,a large scale power system is divided into several subsystems without electromagnetic connections between them and by using the compensation method and the phase sequence parameter transformation technique,any fault problem can be solved without constituting the mathematical model of faulted subsystems.The method can fully utilize the fact that the symmetrical components can be decoupled in symmetrical component coordinates,and can be adaptable to the network changes in topology caused by the faults.The method has been proved to be fast and accurate by a numerical example.
