300MVA脉冲发电机高压变频器调速装置设计及调试

Design and testing of high voltage inverter speed regulating device for 300MVA pulse generator

HL-2M装置300MVA脉冲发电机组的调速装置高压变频器主要由输入和输出部分、功率单元、控制部分组成。对高压变频器进行了调试及试验运行。试验表明其输入谐波含量小,输出波形也是完美正弦波,启动到工作转速的时间为16min,再加速时间未超过5min,能够满足实验放电要求。根据调试情况对空载电流及转子时间常数进行了优化,在空载电流为300A、转子时间常数为1.34s时,其性能为最优。

The high voltage inverter, a speed control device for HL-2 M 300 MVA pulse generator mainly consists of input and output parts, power unit, and control part. The commissioning and test operation of the high-voltage inverter were carried out. The test shows that its input harmonic content is small and the output waveform is also a perfect sine wave. The time from start-up phase to operating speed phase is 16 minutes and the re-acceleration time does not exceed 5 minutes, which can meet the experimental discharge requirements. The no-load current and rotor time constant were optimized according to the commissioning situation, and the performance was optimal at the no-load current of 300 A and the rotor time constant of 1.34 s.
