In this paper

a power quality disturbance integrated generator which can simulate the voltage and current disturbance of the power system is proposed

which can send off such waveforms as voltage sag

voltage fluctuation and flicker

voltage and current harmonics and three-phase imbalance of voltage and current and possesses such features as good waveform output

high power and high voltage level etc.The device adopts the multi-winding transformer

voltage source PWM rectifier

cascade multilevel inverter structure

and the rectification part adopts dual-loop control of voltage and current with good input current waveform and stable DC voltage. The inverter adopts carrier phase shift cascade multilevel with high precision output waveform. The prototype of 1.5 MVA/10 k V power quality disturbance integrated device is developed on the basis of PSCAD simulation and analysis

and the correctness of main circuit and control strategy of the device is verified by the simulation and experimental result.
