双并联处理型综合电能质量调节器的研究
On Double Parallel Processing Type of Unified Power Quality Conditioner
摘要
Abstract
In this paper,a new type of unified power quality conditioner was proposed,which can realize unified power quality conditioning similar to the traditional UPQC by connecting a set of three-phase reactor between the power source and the load,and connecting two inverters respectively to both ends of the reactor in parallel.The device is simple in structure and easy to control.The system control strategy is based on power control,and the basicidea is that the active power of the load under the rated voltage is supplied by the power supply through the connected inductor;the load required harmonic power and reactive power are supplied by the load-side inverter;thus the load voltage compensation and active filtering can be realized.The source-side inverter provides the reactive power current component of the inductor current and realizes the source power factor adjustment.Simulation results show that when the power supply voltage sag occurs,the load voltage can be compensated to rated value by the device in half fundamental frequency cycle;when the load current contains harmonic wave and reactive power components,the device can adjust the supply current to fundamental sinusoidal current in-phase with the source voltage.关键词
