摘　　要：本文研究基于逆推滑模的分布式光伏逆变器并网控制方法,实时稳定追踪分布式光伏发电系统并网参考电流,保证系统并网运行稳定性。结合分布式光伏发电系统结构及其并网逆变器数学模型,构建包含自适应逆推滑模控制器的逆变器并网总体控制模型,结合Lyapunov函数设计自适应逆推滑模控制器,实现对逆变器并网输出电流的控制,结果显示,在该方法的控制下,可实现对处于不同并网运行工况下逆变器并网输出电流的有效控制,令逆变器并网输出电流可持续稳定追踪各并网工况下系统的并网参考电流值,并保证输出电流的质量,满足并网要求,保证系统稳定运行。The grid-connected control method of distributed photovoltaic inverter based on backward sliding mode is studied to track the grid-connected reference current of distributed photovoltaic power generation system in real time and stably to ensure the stability of grid-connected operation of the system.Combined with the distributed photovoltaic power generation system structure and the grid-connected inverter mathematical model,the overall grid-connected control model of the inverter including adaptive push-back sliding mode controller is constructed.Combined with Lyapunov function,the adaptive backsliding mode controller is designed to control the grid-connected output current of the inverter.The results show that under the control of this method,it can realize the effective control of the grid-connected output current of the inverter under different grid-connected operating conditions,so that the grid-connected output current of the inverter can continuously and stably track the grid-connected reference current value of the system under each grid-connected operating condition,and ensure the quality of the output current,meet the grid-connected requirements,and ensure the stable operation of the system.
