摘要
对于光伏并网逆变器,最大功率点跟踪MPPT设计是一项关键内容。本文从太阳能电池阵列理论模型出发,在分析其物理特性及数学模型基础上,提出几种MPPT方法。结合光伏并网逆变器理论分析及实际的光伏系统的试验运行,提出一种合理可行、指标优化的MPPT方法,即改进的CVT启动变步长扰动观测法,试验结果显示该最大功率点跟踪可使光伏阵列稳定工作在最大功率点附近,证明了设计的正确性。
For the grid connected photovoltaic inverter, the maximal power point tracking（MPPT） is a key content for the design. This paper analyzes the physics and math model of PV array, presents several method of MPPT method and the modified CVT Perturbation and Observation method. The experimental results show that the MPPT design makes the PV array workin~ beside the MPP and the design is effective.
