| 摘 要： | 由DSP和上位机组成的控制系统具有很好的信号处理和实时控制能力,主控芯片DSP对需要的直流电流、直流电压信号进行采样和平滑处理,得到较为稳定的直流电流和电压采样结果,有利于光伏逆变器最大功率跟踪的实现。上位机通过485总线发送命令控制由2台5kVA光伏逆变器组成的并联系统,使各个单模块在最大功率跟踪和稳流工作模式之间稳定转换。理论分析和实验结果表明该方法对并联系统具有较理想的控制效果。

| Abstract: | The parallel PV inverter control system is a real-time control system,which need a very high require of signal detection and control methods.The method Based on DSP and PC can achieve the control of parallel system.Control Control system get more stable DC current and voltage sampling results after smoothed by DSP,witch is conducive to the realization of maximum power tracking control.PC send commands through the control bus 485 to control the parallel system of two 5kVA PV inverter, so that each single module can conversion stability between inthe maximum power tracking and the steady flow mode.Theoretical analysis and experimental results show that the method of the parallel system has better control effect. |
