多机系统状态方程的动态分解

Dynamic Decomposition of State Equation in Multi-machine Power System

简要地叙述了一个大电力系统状态方程的形成 ,并介绍了一种分解此状态方程 ,也就是分解此大电力系统的方法。分解后子系统的动态行为与分解前基本相同。此分解方法可称为“动态分解”或“动态分割”。将此分解方法应用于国内某一大电力系统 ,其结果表明该方法是有效的。

Formation of the system state equation is described and a new method of decomposition of the system state equation i.e. the decomposition of the system into parts is proposed., The dynamic behavior of the decomposed parts is kept nearly the same before and after the decomposition. It may be called as the “dynamic decomposition'. The results show that the proposed method of decomposition is effective according to its application in a large power system in China.This decomposition provides the foundation of distributed and coordinated control of a large power system.
