| 摘 要： | 提出了一种采用脉宽调制原理控制的具有动态串联补偿功能的故障限流器。它主要由以脉宽调制(Pulse Width Modulation,缩写为PWM)原理控制的电感、开关控制的电容器组、限流电感构成。正常时,通过控制投切的电容器组,实现可控串联补偿功能,故障时,通过改变脉冲的占空比可以得到变化的阻抗,达到可控限流目的。用MATLAB进行数字仿真证明了此装置的有效性。

| Abstract: | A fault current limiter controlled by PWM is proposed.It is composed of a reactor which is controlled by pulse width modulation(PWM),a series of capacitors,and a limiting reactor.The compensation is controlled by the capacitors' switching on and off in steps,while variable reactance can be realized on duty of ratio control,and the goal of controllable current limitation can be achieved.The digital simulation proved the efficiency of the device with MATLAB. |
