摘要
通过仿真实验,分析与研究了三相光伏并网发电系统的控制策略.首先建立了太阳能电池的数学模型,采用基于干扰观测算法进行最大功率点跟踪;然后介绍了三相光伏并网发电系统的结构,并采用空间矢量SVPWM控制器对逆变器进行并网控制;最后在Matlab/Simulink软件上进行了仿真实验.结果表明,SVPWM逆变控制策略优于传统的滞环电流逆变控制策略.
The control strategy of the three-phase PV grid-connected system is analyzed and studied in simulative experiment. First, a mathematical model of solar ceils is established, then the algorithms based on perturb ＆ observe to track maximum power point is used. Secondly, the structure of three-phase PV grid-connected system is introduced, and the space vector SVPWM controller is used to control the grid-connected inverter. Finally, the simulative results on Matlab/ Simulink software show that SVPWM inverter control strategy is superior to the traditional hysteresis current inverter control strategy.
