Design of single-phase photovoltaic grid-connection system based on STM32
摘要
Abstract
A single-phase PV ( Photovoltaic) grid-connection design scheme based on STM32 is proposed in this pa-per.Firstly, the mathematical simulation models of incremental conductance method and active frequency drift are es-tablished, which applied to MPPT ( maximum power point tracking) and islanding detection.Then, the prototype is designed, which using STM32 as the core processor, adopting composite control strategy based on PLL and grid volt-age front feed-forward compensation, combining BUCK charge control circuit, interleaved fly-back converter circuit, full-bridge inverter circuit, signal adaptation and detection circuit.Finally, test results show that the prototype is sta-ble and reliable, the harmonic content THD and islanding detection time consuming meet the requirements of relevant standards.关键词
