摘要:
针对含有储能元件的分布式发电系统存在直流母线电压难以准确控制的缺点，提出了将PR控制器和PI-type调节器相结合的控制方法来实现直流母线电压的稳定控制。PR控制器对频率为谐振频率的正弦信号可以实现无静差控制，PI-type调节器在谐振频率处进行零极点的补偿来实现静态误差的控制。通过PI-type调节器后的电流与交流侧输出电流进行比较，产生的开关信号调节占空比来实现对直流母线电压的控制。仿真结果表明交直流混合微电网在孤岛模式下交流侧母线电压不稳定时，该文方法能使直流母线侧电压实现稳定控制且交流侧电压和电流
Abstract:
Distributed generation system for contain energy storage element is difficult to accurately control dc bus voltage, A control method combining PR controller and PI-type regulator is proposed realize the stability control of DC bus voltage. No static error control can be realized in PR controller for the frequency of the resonant frequency of the sinusoidal signal, PI-type regulator achieve the static error control with zero-pole compensation at the resonant frequency, the comparison the current through the PI-type regulator with the output current of AC side by producing switch signal regulating duty ratios to realize the DC bus voltage control. The simulation results show that the distortion of the voltage of AC side in ac/dc hybrid microgrid operates in an island mode, this method can achieve the stability of the DC bus voltage and voltage and current distortion rate can meet the requirements of normal operation, at the same time improve the ability to resist disturbance of the whole system.
