摘  要:随着非线性负荷的大量增加以及系统中各种干扰造成的配电网电压畸变将影响许多电力用户 的正常用电,由此可能造成巨大的经济损失。本文介绍了串联型电能质量补偿器的工作原理 ,在补偿器中采用了基于广义瞬时无功功率理论(Park 变换)的检测方法。仿真和实验结果 表明,串联型电能质量补偿器可抑制电网电压中的不对称。波动以及谐波等各种畸变,从而 满足电力负荷对供电质量日益提高的需求。The voltage distortion, which is caused by various kinds of disturb ances in distribution system and the outstanding increment of nonlinear loads, w ill influence the performance of some loads which are sensitive to the waveform and lead to enormous economic losses. In this paper, the principle of a series power quality compensator which uses Park transformation based detecting method is presented. The results of simulation and experiment show that this kind of co mpensator can effectively suppress the disturbances such as asymmetry, sags and swells, as well as harmonics in the system voltage. Using this compensator the r equirement of power quality from electric energy consumers can be satisfied.
