阐述了采用最大功率跟踪控制(Maximum Power Point Tracking,简称MPPT)的原因,比较了几种MPPT实现方法的优缺点.基于增量电导法(Incremental Conductance,简称INC)研究了MPPT参考电压初值的设置方法,提出在MPPT参数初始化程序中,将参考电压初值设定为当前光强和温度对应的开路电压的76%,可使系统开机后能快速跟踪到太阳能电池最大功率点.最后通过原理样机验证了所提MPPT初值设置方法正确性和有效性.

This paper introduces the reason of maximum power point tracking(MPPT)and compares the ways to realize MPPT such as CVT,P&O,and incremental conduetance(INC).Based on the INC,a novel method which chooses the initial reference voltage of MPPT is proposed.In the parameter initialization program of MPPT,the initial reference voltage,which is set as 76%of the open-circuit voltage correspond to the real-time irradiation and temperature,can improve the speed of MPPT during the system start process.A 1 kW prototype of photovoltaic power system for MPPT is built in the lab.The experimental results verify the correctness and effectiveness of the proposed method.
