摘要
文章简要分析分布式光伏发电原理,然后根据瞬时无功功率理论建立数学模型。基于瞬时无功功率的i p-i q检测方法,使用MATLAB对分布式光伏发电接入电网进行仿真实验,对配电网络所产生的谐波进行分析与探讨,通过仿真实验得到相应的谐波波形,并结合FFT分析工具来观察谐波含量。
This paper briefly analyzes the princile of distributed photovoltaic power generation,and then establishes a mathematical model based on the instantaneous reactive power theory.Based on the i p-i q detection method of instantaneous reactive power,MATLAB is used to conduct simulation experiments on the connection of distributed photovoltaic power generation to the power grid.The harmonics generated by the distribution network are analyzed and discussed.The corresponding harmonic waveforms are obtained through the simulation experiment,and the FFT analysis tool is used to observe the harmonic contents.
