400V／100A并联有源滤波装置的仿真与试验

有源滤波器与无源滤波器相比具有较好的滤波性能，能实现在大功率场合下的谐波抑制。根据主电路拓扑结构，设计了其控制电路，包括触发电路、同步信号电路和缺相电路检测的设计。在成熟的p-q和ip-iq两种瞬时无功理论的基础上．提出了一种新的基于瞬时无功理论的三相四线制谐波检测新方法，此方法能将三相电流中的零序电流剔除。最后利用Matlab／Simulink构建了400V／100A并联有源滤波器仿真模型，并通过仿真结果和试验波形验证了该方法的准确性和有效性。

Simulation and Test of 400V/100A Parallel Active Power Filter

Compared with Passive Power Filter, Active Power Filter has the better filtering performance. It can realize harmonics restraint in large power situation. According to the topology structure of main circuit, design their control circuit. It includes design of trigger circuit, locking signal circuit and lacking phase detection circuit . In order to let the active power filter could be used in three-phase four-wires circuits, a new method of harmonics detection is given in this paper, which is based on mature...
