| 摘 要： | 在分析统一电能质量控制器系统结构和工作原理的基础上，根据UPQC的补偿目标，通过建立其状态空间模型，提出了基于二次线性最优控制的开关控制策略来跟踪电压和电流的指定值。电压和电流的基波分量采用全波移动均值提取傅里叶级数基波序分量的方法得到。利用所提方法对负载电流及电网电压畸变进行了计算机仿真，结果证明了所提方法的正确性。

| Abstract: | The structure and function of the Unified power quality conditioner (UPQC) is proposed.The reference values of voltage and current are got based on the compensation object.Switch control strategy to track voltage and current reference values is proposed based on the foundation of State-Space equation of UPQC.The fundamental values of the voltage and current are got based on Fourier series extraction of fundamental sequence components using one cycle moving averaging.Simulation results under source voltage and load current distortion show the correction of the proposed method. |
