Abstract:

扰动观测法是光伏系统MPPT算法中最常用的追踪算法.为了准确实现扰动观测法的追踪效果,该文基于扰动观测法等同于分段恒压控制的思想,推导了扰动观测法控制的调整时间公式,分析了扰动观测法控制MPPT系统工作点在光强突变时的运动特性,提出了"错误保持"、"正确保持"、"判断错误"和"判断正确"四个概念,总结了扰动观测法控制MPPT系统工作点的十二种运动情形及其动态效果,仿真结果和实验结果验证了四种典型运动情形.以此十二种运动情形为依据提出了一种对等评价不同扰动观测法控制性能优劣的评判方法,并应用该方法研究固定步长和变步长的暂态性能,结果表明,当判断错误时,变步长控制的动态性能比定步长的更差.该文研究结果有助于改善干扰控制法的动态性能.
