摘要:
针对高压直流输电系统换流器中晶闸管的过电压、过电流故障,采用阻容缓冲器进行器件自身保护,以及基于模糊比例积分(PI)控制理论的电子保护电路作为控制系统保护.仿真结果表明:阻容缓冲电路使系统跟随性更好,系统超调量得到改善,提高了换流站运行的可靠性和稳定性;模糊自适应 PI控制器能实时调整PI参数,使整流电流具有良好的跟踪性和故障恢复性,保证高压直流输电的正常、可靠和稳定运行.
Abstract:
According to the over-voltage and over-current failure analysis of thyristor converter in the high-voltage direct current(HVDC)transmission system, the resistance and capacitance buffer for their own protection and electronic protection circuit based on the fuzzy PI(proportion integration)control theory as control system protection is used for protection design in the paper. The simulation result shows that the application of resistance and capacitance buffer is in better traceability, lower overshoot and improves reliability and stability of converter running. Fuzzy PI controller can adjust the PI parameter in time and makes DC current having good traceability and recovery. It ensures the high-voltage direct current transmission system in normal, reliable and stable operation.
