摘要

提出了一种光伏供电单级逆变器的三环控制方案。将跟踪算法与迟滞控制技术相结合,对该方案进行了改进。前馈回路进行最大功率提取,而其余两个内环保持逆变器的统一功率因数运行。为了研究所提出的控制方案的有效性,在PSIM平台上建立了包括光伏源实现、控制方案和公用事业系统在内的仿真模型。通过仿真结果验证了该概念。

PV Power Tracking Through Utility Connected Single-Stage Inverter
A three-loop control scheme for the PV supplied single stage inverter is proposed in this paper. Integrating the tracking algorithm together with hysteresis control technique evolves this scheme. The feed-forward loop performs the maximum power extraction, while the remaining two inner-loops maintains unity power factor operation of the inverter. To study the effectiveness of the proposed control scheme simulation models are developed in PSIM platform, which includes photovoltaic source realization, control scheme and utility system. The concept is demonstrated through simulation results.
