中文摘要: 引进静止无功发生器装置以改善电网中谐波污染和低功率因数等电能质量问题.采用LCL滤波的三相PWM整流器为拓扑结构,采用基于瞬时无功功率理论的直接电流控制方法,即ip-iq控制方法.基于不同补偿目标提出了两种控制方案并进行了分析,对其中的一种方式给出了基于Matlab/Simulink下的仿真.仿真结果验证了该控制方式的可行性和正确性.
Abstract:For existing power system harmonic pollution and low power factor problem, a static var generator device based on main circuit configuration of three-phase inverter with LCL filter is proposed to improve power quality. A direct current control strategy with an instantaneous reactive power theory, namely ip-iq control methods, is presented and analyzed. Two specific control methods are presented and their formulas are also given respectively. The proposed strategy system is simulated by using the toolbox of Matlab/Simulink. Finally, the feasibility and effectiveness of the proposed method is verified by simulation results.
