多机光伏并网逆变器并联运行的孤岛检测方法研究
Research on detection method of parallel operation of multi machine photovoltaic grid-connected inverter
摘要
Abstract
Island detection technology is one of the key technologies of photovoltaic grid connected power generation system.Aiming at the shortage of the traditional AFDPF method,an improved active frequency drift positive feedback (AFDPF) detection method is proposed,and the basic principle and the non-detection zone (NDZ) of the improved AFDPF method are analyzed.The simulation modeI of two PV grid connected inverter is established by the Matlab/Simulink simulation software,and the simulation research of the traditional AFDPF and the improved AFDPF island detection method is carried out in the single inverter and the two inverter operation.The simulation results show that the improved AFDPF island detection method can accurately detect the isolated island under single stage and two inverters operation conditions,and meet the standard of IEEE std.929-2000.关键词
