摘　　要：针对火电厂低电压穿越改造实验,设计一种便携式电压跌落发生器,主电路选用三相交流调压电路,控制电路通过改变切换开关在两个可调电位器之间的调节位置,可实现两路交流电压的输出切换,从而产生电压跌落或电压升高的过程。实验结果验证便携式电压跌落发生器满足设计要求。According to the experiment of the low voltage ride through transformation, this paper designed a portable voltage sag generator, select three-phase AC regulating circuit as main circuit, control circuit can switch two AC voltage output by change the position of two adjustable resistor, then you can get the process of the voltage drop or the voltage rise. Experimental results proves the portable voltage sag generator can meet demand.
