统一潮流控制器协调控制技术的研究

Study on harmonizing control technology of unified tidal flow controller

统一潮流控制器(UPFC)是一种典型的柔性交流输电系统(FACTS)装置,它能通过其串联侧进行移相、节点电压等控制,还可以在并联侧对输电系统进行无功补偿。通过对三相换流器基本解耦控制方法的研究,得到UPFC串联、并联侧装置的控制方法,使得具有强烈非线性的UPFC控制更加灵活稳定和快速的特性,并具有很强的鲁棒性。通过仿真证实了该方法的可靠性。

Unified tidal flow controUer （UTFC） is a typical flexibility AC transmission system device, the phase can be shifted and node point voltage controlled by its series converter and reactive power compensation can also be done to power transmission system by its shunt converter. The controlling method of UTFC＇s series and shunt converter was gained by studying on the basic three-phase converter decoupled controlling method, which makes UTFC more flexible, steady, faster and robust, and it is verified that the method is reliable through simulating.
