Abstract


The use of solar energy has become the hot spot of the current domestic and international research and concern . In this paper, the photovoltaic power generation system study , the characteristics of the PV array calculation method , maximum power point tracking technology and network control strategy of the inverter and anti- islanding detection technology analysis and research . This paper first analyzes a PV array characteristics of engineering calculation method , and the method of application of photovoltaic grid-connected inverter test system in a set of industrial field . Followed by discussion of the two commonly used maximum power point tracking algorithm , and a focus on exploration interpolation perturbation method . MATLAB \\ SIMULINK environment , the method of simulation studies . Then create a three-phase single-stage photovoltaic grid-connected inverter in three-phase stationary coordinate system and the mathematical model of the two-phase rotating coordinate system , focusing on analysis of double-loop control strategy based on synchronous coordinate system of direct current control technology . Application MATLAB \\ on SIMULINK Simpower Systems 's toolbox to build the entire PV grid power system simulation model of control technology based on the synchronous coordinate system of direct current double-loop control strategy simulation study . Finally, the shortcomings of the passive islanding detection method , to explore a combined anti - islanding detection method ; MATLAB \\ SIMULINK environment , analyze the feasibility of the method .
