摘　　要：提出了一种基于两层无功电压控制模式的配电网无功电压集中-分布协调控制方法,该方法根据控制对象的补偿效果与动作周期的不同,将配电网无功电压控制体系解耦为无功的就地分布补偿与电压的集中优化控制两个层面,建立控制模型并研究了相应的控制策略。最后采用工程算例进行分析验证,计算结果表明所述控制模型与控制策略能够有效降低网损、提高电压质量,具有一定的工程指导意义。This paper proposed a centralization-distribution coordinated control method of reactive power and voltage in distribution network based on double-layer reactive power and voltage control mode. This method decouples the control system of reactive power and voltage into two levels called local distributed compensation of reactive power and centralized optimal control of voltage by the difference between compensation effect and operation cycle of control objects. Then builds the control model and its strategy. It takes an engineering example to verify the method at the end of the article, and the result indicates that active loss got decreased and voltage quality was improved obviously.
