| 摘 要： | 根据已有的磁阀式可控电抗器在PSCAD仿真软件中建模,对基于磁阀式可控电抗器型的可调谐滤波器进行了软件仿真。控制目标是通过改变电抗器的电感值,使滤波支路所需滤除次数的谐波电压和谐波电流同相,保证滤波支路在谐振点工作。控制的主要环节包括滤波、鉴相与PI调节三个部分。从仿真结果可看到,可调谐滤波器能够工作在谐振点。

| Abstract: | The magnetic valve controllable reactor has been modeled in PSCAD according to its real parameters.The simulation and experiment of the magnetic valve controllable reactor based tunable filter have been done.It is aimed to make the harmonic voltage and current in the filter branch have the same phase via adjusting the reactor,So the filter can be kept working at the vesonance frequency.The control system also includes filtering,phase-detection and PI adjustment.The result of the simulation and experiment indicate that the tunable reactor can be kept working at the resonant frequency. |
