| Abstract: | A large capacity and high-precision combination switch and a program controller with multi-channel reference voltage are developed, which can accurately control the switching angle and realize precise control of short-circuit time, transformer inrush current experimental angle and switching time of transforming faults in power system. It can reproduce all kinds of fault waveforms in real power system in dynamic simulation laboratory, and carry out fault experiment and fault waveform analysis at different time from 0 to 360°. The experiment shows that the control accuracy of the switch can be increased from ±5 ms to ±0.1 ms, which meets the needs of scientific research and experiment. |
