【摘要】 在充分考虑光伏发电系统中各重要环节数学模型的基础上,建立了光伏并网发电系统的Matlab/Simulink仿真模型。针对传统仿真方法中快速性较差的缺陷,采用逆变器的等效开关模型,简化了仿真运算量并显著提升了仿真速度。采用dSPACE+DSP仿真平台实现了步长为8μs的系统实时仿真,并通过扰动光照、温度输入验证了实时仿真的有效性。更多还原

【Abstract】 The paper establishes a detailed simulation model of Photovoltaic(PV) generation system based on Matlab/Simulink.Its inverter—based simplified model,i.e.the switching-function equivalent model is proposed and simulated,overcoming the limit of traditional method in simulation speed.In addition,the paper establishes the real-time simulation platform with the time step-size of8 s based on dSPACE and DSP controller,and verifies its validity and utility by evaluating the system performance under solar irradiance/temperature disturbance.更多还原
