基于LabVIEW太阳能电池最大功率点跟踪研究

为了获得太阳能电池最大功率点时的电压、电流、功率数据,根据太阳能电池模型及其输出功率曲线的单峰性,提出了利用LabVIEW和电子负载实现太阳能电池最大功率点跟踪(Maximum Power Point Tracking,简称MPPT)方法.该方法以LabVIEW和电子负载为核心,实现采集并记录电子负载的电压、电流、功率数据的功能,并根据这些数据实时对电子负载进行控制,完成人阳能电池的MPPT.该方案稳定可靠、开发周期短.

Research of Maximum Power Point Tracking for Photovoltaic Module

In order to obtain values of voltage,current and power when the photovoltaic module is operated at the maxi-mum power condition,LabVIEW and electronic-load are used to implement the maximum power point tracking(MPPT) of PV module based on engineering analytical model of silicon solar cell and the one-peak characteristics of PV module's power output.As the key parts of this solution,the IabVIEW software is used to acquire and store data,then electronic-load is controlled to implement the MPPT.This method is stable,reliable and efficient.
