根据对光伏系统户外监测的需求，本文提出了结合恒定电压法与基于电阻矩阵增量导纳法的I-V曲线扫描算法，并阐述了样条插值曲线的重构方案。对上述算法的误差来源及复原曲线进行了分析，并根据具体的应用环境给出了该算法的具体实现。在此基础上给出了监测系统的架构设计及应用方法。依据该算法对实际监测的太阳能电池参数的准确性进行了仿真与实验。结果表明，本方案简便易行、扩展性好且具有较高的测量精度，可为户外光伏系统工作特性监测领域的设计提供一种较有竞争力的技术方案。

According to the need for PV system outdoor measurement, an algorithm based on constant scale and incremental con-ductance algorithm is presented. An interpolation is employed for I-V curve reconstruction. The error source and reconstructed curve is analyzed too. Corresponding system design and implicating method are discussed. Simulations and experiments are executed for al-gorithm verification. The results show that this method can provide high-precision PV characters measuring with low complexity. It could be a competitive candidate for outdoor distributed PV system measuring in the future.
