摘要

预计，在未来，公用事业服务提供商将执行更严格的功率因数和谐波标准。因此，人们正在努力使电力电子系统或任何其他负载吸收无功伏安，使其表现为与公用事业电压相相的线性负载吸收电流。实现这一目标的解决方案之一是采用有源电力滤波器(APF)。提出了一种串联有源滤波器和并联有源滤波器相结合的统一电能质量调节器(UPQC)控制技术。本文讨论了一种基于单位矢量模板生成的控制策略，重点研究了电力系统中电压谐波的抑制问题。基于Matlab/Simulink的Simpowersystem (SPS)仿真结果验证了所提控制技术的有效性。

A simple new control technique for unified power quality conditioner (UPQC)

It is expected that, in future, utility service providers will enforce more strict power factor and harmonic standards. Therefore, efforts are being made so that power electronic system or any other load drawing reactive volt-amperes is made to appear as linear load drawing current in-phase with the utility voltage. One of the solutions towards this end is to employ active power filters (APF). This paper presents a control technique for unified power quality conditioner (UPQC), which is a combination of series APF and shunt APF. A control strategy based on unit vector template generation is discussed in this paper with the focus on the mitigation of voltage harmonics present in the utility voltage. Simulation results based on Simpowersystem (SPS) of Matlab/Simulink are presented to verify the effectiveness of the proposed control technique.
