摘　　要：为使光伏系统性能测试时不受环境因素影响,现提出一种带有追踪定位功能的光伏电池模拟器的实现方法。该方法通过上位机LabVIEW和下位机可编程电源实现,可模拟实验需要的各种温度和光照条件,实现“全天候”正常工作的能力。可随时提取负载状态,使其输出电压追踪光伏电池伏安特性曲线,并可在曲线上实现最大功率点和负载静态工作点的定位追踪。该方法可在线观测并可灵活变更参数,创新地采用先构建特性曲线再插值求工作点的方法实现追踪定位,成本低廉且方便高效,为光伏发电系统的各项理论验证和特性测试提供了实验基础。In order to ensure that the performance of photovoltaic system is not affected by environmental factors,an implementation method of photovoltaic cell simulator with tracking and positioning function was proposed.The method was realized by the upper LabVIEW and the lower programmable power supply,which could simulate the various temperatures and light conditions required by the experiment,and realized the ability of"all-weather"normal operation.The load state could be extracted at any time to make the output voltage track the volt-ampere characteristic curve of the photovoltaic cell,and the maximum power point and the static operating point of the load could be located and tracked on the curve.This method could be observed online and parameters could be flexibly changed.The method of constructing characteristic curve and then interpolating the working point was innovatively used to realize the tracking and positioning.It is proved that the method is cheap,convenient and efficient,and provides the experimental basis for the theoretical verification and characteristic test of photovoltaic power generation system.
