摘　　要：介绍了STS的拓扑结构和工作原理,详细阐述了滑动窗口模型有效值法、三相绝对值之和法和dq变换法三种断电快速检测方法的工作原理,并用计算机仿真对比分析了以上三种断电快速检测方法的优缺点。研制了一台120kVA容量的STS实验样机并进行了验证实验,实验结果验证了理论分析的正确性。Static transfer switch （STS） topology and working principle are introduced. Three kinds of rapid detection method of power cut （sliding window RMS method, absolute value of the three phase method and dq transform method） are elaborated. Advantages and disadvantages of the above three detection methods are contrasted by computer simulation. STS experimental prototype with 120kVA capacity is developed. And confirmatory experiment is carried out. The experimental results verify the correctness of the theory analysis.
