基于STM32F051控制的太阳能并网发电系统设计
资料介绍
设计了一种1kW太阳能并网发电系统,主要包括前级DC/DC升压模块和DC/AC逆变模块,整个控制的核心芯片采用ARM系列的STM32F051。前级DC/DC升压模块,主要利用全桥LLC谐振电路实现了前级电压的泵升,为后级提供了稳定的电压;后级DC/AC逆变模块,主要利用单相电压型逆变电路,其逆变控制系统采用SPWM电压电流双环控制,使并网电流与电网电压同频同相。在MATLAB/Simulink仿真环境下对全桥LLC谐振电路和单相全桥逆变电路进行仿真,得到了谐振网络两端电压、谐振电流以及电网电压、并网电流的仿真结果,为今后太阳能并网发电系统的改进和优化提供了依据。
The 1kW solar energy grid generation system was designed.It includes the front-end DC/DC booster and DC/AC inverter module,and the core of the whole control chip adopts ARM series STM32F051.The front-end DC/DC booster module can make the voltage level go up by using the whole bridge LLC resonant circuit.The level DC/AC inverter module can adjust the grid current frequency and phase to the same as the network voltage by using single-phase voltage type inverter circuit,which adopts SPWM voltage and current double loop control.Finally LLC resonant circuit of the whole bridge and single-phase inverter circuit of full-bridge are simulated by MATLAB,and the simul...
