变电站电压无功优化控制器

Substation′s V Q Optimal Control Equipment

根据电网的终端变电站的二次母线（１０ｋＶ或３５ｋＶ）的接线特点，以母线电压和网损作为目标函数，以有载调压变压器和并联电容器作为调节手段，推导出变电站电压无功控制器的控制规律，并着重分析了抽头变化、并联电容器的投切效果与系统网络参数的关系．此外本文还论述了ＶＱＣ变电站电压无功控制器的硬件、软件设计思想、主要特点及采用的新技术；介绍了现场运行的情况；指出了ＶＱＣ—Ⅱ型变电站电压无功控制器对ＶＱＣ—Ⅰ型的改进之处．

Based on the characteristics of the secondary Trunk(10kV or 35kV) at the terminal substation,taking the voltage profiles and real power loss as the objective function the switched capacitor and load ratio voltage transformer as the controlling means,this paper analyzes the relation of electric power network coefficients and effects of load ratio voltage transformer and switched capacitor.The paper also introduces the function,the main feature,hardware and software design method and new technology,the operation condition of VQC equipment and point out the improvement of VQC Ⅱ substation′s optimal control equipment for VQC Ⅰ.
