Abstract State grid company recently released the "Technical Manual Related to High&Low Voltage Ride Through of A Class of Auxiliary Inverter in Large Steam Turbine-Generator (draft)" and put forward the requirement of high & low voltage ride through ability. But there is a lack of the testing equipment. This paper proposes a 10kW voltage sag & swell generator used in high & low voltage ride through ability test for low-voltage auxiliary inverter. Its main topology is a back-to-back three-phase PWM converter. The generator can realize balanced or unbalanced voltage sag & swell from 0 to 130%UN. Experiment shows that this device can output target voltage accurately and rapidly and meet the requirements of high&low voltage ride through ability test for low-voltage auxiliary inverter in thermal power plant.
