分布式潮流控制器控制系统设计与应用

Design and Application of Control System for Distributed Power Flow Controller

分布式潮流控制器(DPFC)通过向线路注入串联补偿电压来增加或减少线路的电抗,实现了线路潮流调节功能,提升了线路输送能力,有效解决了电网供电断面超限问题。对DPFC主电路拓扑、控制架构、控制策略及保护配置进行了分析,设计了DPFC装置控制系统。经工程应用验证,DPFC装置可实现线路潮流调节功能,并可有效解决电网供电断面超限问题。

Distributed power flow controller(DPFC)works as increasing or reducing the reactance of the transmission line by injecting series compensation voltage to transmission line,it is capable of regulating power flow,improving the transmission capacity of the transmission line,and effectively solving the problem of the limit-exceeding of the power supply section of the power grid.The DPFC install control system is designed based on the analysis of DPFC main circuit topology,control architecture,control strategy and protection configuration.It has been verified by engineering application that DPFC device can realize the function of line power flow regulation,and effectively solve the problem of the limit-exceeding of the power supply section of the power grid.
