摘　　要：在“源随荷动”的电网调度模式下,市场存在不同交流供电制式的需求。为满足市场需求,设计了一种兼容多种交流供电制式的不间断电源系统。系统中通过切换装置进行制式选择,根据选定的制式进行不同的驱动控制,从而实现多种交流供电制式的兼容。为提高不间断电源系统的可靠性,还提出了一种制式兼容的容错机制。最后通过一台40 kV·A/36 kW样机进行实验,结果表明该系统能够兼容多种交流供电制式,验证了设计的正确性。Under the power grid dispatch mode of"source follows load",different AC power supply modes are required in the market.To meet market demand,an uninterruptible power supply(UPS)system compatible with various AC power supply modes was designed.The modes of the system were selected by switching devices.According to the selected mode,different methods of driving control were carried out,and thus the compatibility of various AC power supply modes was realized.To improve the reliability of uninterruptible power supply,a faulttolerant mechanism with compatible modes was also proposed.Finally,an experiment was conducted on a 40 kV·A/36 kW prototype.Experimental results demonstrate that the system can be compatible with various AC power supply modes,by which the correctness of the design was verified.
