基于移相器统一特性的潮流控制

The Common Character of Phase Shifter Based Power Flow Control

本文根据移相器的共同性质，在保持原始网络节点导纳矩阵对称性的条件下，推导了节点等效附加注入电流和功率的统一表达式，并将此式用于修正移相器参数的选代过程中。实例分析表明，本文方法能统一地分析多个不同种类的移相器对潮流控制的作用，具有适应性强的特点。

Based on the common character of phase shifter, this paper derives a set of unified formulae of the bus equivalent injected current and of the bus equivalent injected power with a symmetrical Y-bus matrix preserved. On this basis, a unified power flow control algorithm is described and the unified formulae are also used in this algorithm. Examples of some test systems show that the method in this Paper can analyze the effects of various Phase shifters to power flow control at the same time. Therefore,this method is of powerful suitubility.
