摘要 逆变器并联被越来越多地用于提高电源系统的容量、可靠性等性能。针对中频逆变器并联系统对相位要求比工频系统严格得多的特点,提出了一种基于传统下垂法的改进型并联控制策略。系统中应用了相位同步线来提高相位的同步性能,并采用相位容差控制提高系统的动态性能。仿真和实验结果验证了此控制策略的可行性。 Parallel inverters are increasingly used to improve the power system's capacity,reliability and other prop-erties.As the requirements for phase accuracy in 400 Hz medium frequency parallel inverters system are more rigorous than which 50 Hz parallel inverters system,the paper proposes a modified method based on traditional droop method in parallel system.A phase synchronization signal is used to enhance the phase synchronization performance,the phase tolerance control is used to improve the system dynamic performance.Simulation and experimental results verify the feasibility of the control strategy.
