摘要

光伏系统最大功率点跟踪(MPPT)控制是光伏系统的关键控制技术,但目前的控制器存在开发周期长、成本高、验证复杂等缺点,对不同控制算法进行全物理仿真或全数字仿真也存在不足。本文通过对各种MPPT算法的研究,结合改进的MPPT算法,进行了硬件控制器的设计,然后利用Opal-RT公司开发的RT-LAB对数字主电路进行了数模混合实时仿真。通过与改进MPPT算法的控制效果和传统MPPT算法的控制效果对比,验证了改进MPPT算法的有效性和优越性。doi: 10.5829 / idosi.ije.2016.29.10a.07

Control Simulation and Experimental Verification of Maximum Power Point Tracking Based on RT-LAB (TECHNICAL NOTE)
The maximum power point tracking (MPPT) control in a Photovoltaic system is the key control technology, however present controllers have the disadvantages of long development cycle, high cost and complex verification, and there are some disadvantages carrying out totally physical simulation or totally digital simulation of different control algorithms. This paper carried out design of hardware controller by researching different kinds of MPPT algorithms together with the improved MPPT algorithm, then digital-analog hybrid real-time simulation was carried out based on the digital main circuit using RT-LAB developed by Opal-RT company. Effectiveness and superiority of the improved MPPT algorithm were verified in comparison with control effects of the improved MPPT algorithm and control effects of traditional MPPT algorithms. doi: 10.5829/idosi.ije.2016.29.10a.07
