三相四线制并联型有源电力滤波器在建筑中的应用

Three-phase Four-wire Shunt Active Power Filter Applications in Buildings

主要针对目前建筑内谐波和无功问题相伴出现且严重影响供配电系统正常运行的问题,提出了在单相非线性负载比例较高的办公、实验等建筑内,采用三相四线制有源电力滤波器并联补偿的方法来治理供配电系统谐波、提高系统功率因数。介绍了三相四线制有源电力滤波器装置的工作原理和技术特点、现场应用数据、系统仿真验证理论设计的正确性以及现场运行后的补偿效果。

The paper, for the problems of current harmonics and reactive problems that seriously affect the normal operation of supply and distribution system, proposed in office, laboratory and other buildings with higher proportion of single-phase nonlinear loads to use three-phase four parallel-wire active power filter compensation method for control the supplyand distribution system harmonics, improve the system power factor. The work principles and technical characteristics of three-phase four -wire active power filter device, the field application data, the correctness of the system simulation verification theoretical design, and the compensation effect after field running were introduced.
