摘　　要：通过使用静态转换开关(STS),实现光伏微网系统供电连续性和能量管理优化。针对STS的抗干扰能力和切换时间问题,改进了双向可控硅触发电路和dq变化法电压暂降检测方法,并设计了一个基于STM32F103VC的3.6 kW静态转换开关模块,改善了STS抗干扰能力,切换时间缩短至2.5 ms。该静态转换开关已经成功应用于3.6 kW的光伏微网系统中。实验结果验证了电路的可行性。By STS （static transfer switch）, photovoltaic micro-grid system for continuous power supplement and energy management optimization was realized. Focusing on the problem of ST$ anti-jamming capability and switching time, approaches were proposed to meliorate the trigger circuit for silicon controlled rectifier and dq transformation method of voltage sag detection. Based on the analysis, a 3.6 kW static transfer switch module with STM32F103VC controller was designed, and was applied to a 3.6 kW photovoltaic micro-grid system successfully. The STS anti-interference ability was effectively improved, and the switching time was reduced to 2.5 ms. Experiment results ultimately verify the correctness of the model.
