REACTIVE POWER SECURITY CONTROL IN HIGH VOLTAGE AC/DC HYBRID SYSTEMS

本文提出一种高压交直流并联系统的无功校正安全分析方法。采用线性规划法协调控制变压器分接头、交流系统的无功电源以及高压直流系统的可控变量,使之在校正节点电压的同时,达到经济运行的目的。 建立了高压交直流并联系统无功校正安全分析的线性规划模型,编制计算机程序,进行实例计算,得到了满意的结果。

A method of reactive power security control in high voltage AC / DC hibrid systems is presented in this paper. A linear programming schcme is adapted to give a coordinatcd reactive powcr control using conventional reactive power sources, transformer tap, and DC converters in order to correct bus voltage. The effectiveness of this scheme is demonstrated in an example system. The results of calculation in this paper show the correctness of the method and the computer programs.
