In order to test the the working condition of devices such as power transformer, CVT, power capacitor, reactive and harmonic compensator in power quality disturbance environment, a power quality disturbance generator is developed, which can simulate the actual power system to output various forms of power quality voltage and current disturbance. The stability of the DC voltage is realized by use of voltage outer-loop and current inner-loop PWM rectifier control; by use of a control strategy which combines voltage feed-forward and repetitive learning, the high accuracy output is achieved;the control system constructed by DSP+FPGA has good real-time and reliability; the correctness of the design is proved through the tests on 10 kV, 2 MVA industrial prototype.
