为了探索利用IGBT实现的非铁磁三相可控电抗器在实际工程中的运行状况,对利用IGBT实现的三相非铁磁性电抗器电路进行了基于Multisim软件的仿真分析。通过改变仿真电路的参数,探索IGBT实现的非铁磁三相可控电抗器的可控范围,并模拟实际工程中电力系统的不对称运行情况下IGBT实现的非铁磁三相可控电抗器通的输入电流和输入电压的波形,分析该电抗器在不对称工况下的运行状况。结合了工程实践中的实际应用,分析表明此电抗器能够满足现代电力工业对电抗器的要求。

This paper performs a simulating analysis based on the Multisim upon the electro circuit of the unmagnified reactor realized by IGBT,during which we could investigate the panorama of the operating state of Three-phas Controlled Reactor Realized by IGBT in engineering practice.Through altering the parameter of the simulated electro circuit the paper investigates the controllable scope that the reactor could achieve,and then simulates the asymmetry operating of the electronic system in engineering practice;and thus by observing the waveform of the received current and the input voltage,we could conclude an exact judgment on the operating state of the reactor.Hereby associated with the engineering practical application,the analysis bespeaks that the reactor is fully capable of satisfying the demands of modern electricity industry.
