基于后台监控系统的电压无功综合控制

Integrated control of voltage and reactive power based on monitoring system

电压无功综合控制(VQC)是提高电压合格率、降低网损、提高系统稳定性的有效手段。分析比较了VQC的多种实现方式及控制策略的优缺点,在此基础上提出了一种在当地后台监控系统实现的,基于预测算法的电压无功综合控制系统,并描述了具体的实现方案和特点。为了适应各电压等级变电站复杂多变的运行方式,系统采用面向对象的设计思想,可以实现多变电站、多运行方式的控制功能。

Voltage and reactive power integrated control （VQC） is an effective means to increase rate of qualified voltage,reduce grid losses,and improve the system stability. A comparative analysis on the advantages and disadvantages of the multiple ways and control strategy is conducted.Upon this, a new method based on predict algorithm and local monitoring system is presented,and implementation of the method is also described.Because of the complicated operation mode,the object-oriented design thought is used to realize the control function of multiple substation and operation mode.
