Abstract

Based on the simulation model of on-load capacity regulation transformer

instantaneous overvoltage and overcurrent of high and low-voltage side switches have been simulated and analyzed under different control strategies.The simulation results show that instantaneous voltage and current of switches can be controled under several kilovolts and several hundred amperes.Using thyristor as capacity regulation switch to realize on-load capacity regulation of transformer has practical meaning for power saving and capacity regulation transformer popularization and application

and it supplies theory basis.
