摘　　要：文章提出一种基于边沿触发控制的并网逆变器控制策略,应用该控制方法设计了一套具备储能功能的微电网并网装置。该装置能够存储光伏电池发出的电能,同时能将电池能量经逆变器并网输出。实验表明,与现有小功率并网逆变器相比,使用整形电路替代复杂的锁相环,基于边沿触发的控制策略实现逆变电流与电网电压锁相,控制简便可靠,提高了系统稳定性。This paper presents a control strategy of grid-connected inverter based on edge trigger control,and uses this control method to design a set of microgrid grid-connected device with energy storage function.The device can store the electric energy emitted by the photovoltaic cell and output the battery energy through the grid-connected inverter.Experiments show that compared with the existing low-power grid-connected inverter,using the shaping circuit to replace the complex phase-locked loop and the control strategy based on edge trigger to realize the phase-locked between the inverter current and the grid voltage,the control is simple and reliable,and the system stability is improved.
