直流发电机的控制策略

Control strategy for DC generator

提出了虚拟直流发电机控制策略,即模拟直流发电机特性的变换器控制方案。通过虚拟直流发电机控制变换器可维持负荷侧电压处于额定值状态,且于母线电压受到扰动下降时,尽可能减少母线功率取用,恢复母线电压,并在电压变化时缓解震荡,避免剧烈冲击,从而保障直流电网稳定性与可靠性。通过控制策略仿真分析表明,虚拟直流发电机控制策略超调性与可行性十分突出,值得大力推广应用。

A virtual DC generator control strategy was proposed,which was a converter control scheme that simulates the characteristics of the DC generator.Through the virtual DC generator control converter,the load side voltage couldn be maintained at the rated value,and when the bus voltage was disturbed and dropped,the bus power was reduced as much as possible,the bus voltage was restored,and the shock was relieved when the voltage changes to avoid severe impact,So as to ensure the stability and reliability of the DC grid.The simulation analysis of the control strategy showed that the overshoot and feasibility of the virtual DC generator control strategy were very prominent and it was worthy of vigorous promotion and application.
