Abstract: In order to research on the secondary device configuration of grid-connected photovoltaic (PV) power station, this paper adopted the software of Matlab/Simulink to build the model of grid-connected PV power system and analyzed its working principle. Taking certain 35 kV grid-connected PV power station for example, this paper illustrated the configuration of the secondary device. The actual operation shows that the configuration has the clear principle with stability and reliability, which provides reference basis for the future large-scale PV grid-connected power generation.
Key words: photovoltaic power station; grid-connected system; secondary device; configuration principle
