摘要
基于光伏电池、风机的输出特性、物理模型和最大功率点跟踪(MPPT)原理,在Matlab/simulink仿真环境中建立了通用的太阳能电池板模型、风机模型以及两者MPPT电路模型。在分析总结风光MPPT策略的基础上,提出风光MPPT模块采用同一变步长扰动策略的方案,以实现减少设备复杂性,降低成本的目的。利用所建立的模型对此策略进行仿真所得到的曲线验证了光伏电池、风机模型的正确性和两者MPPT电路的功率跟踪效果。该系列模型和策略可用于风光互补发电系统的动态仿真,为提高小型风光混合供电系统的能量利用效率和供电质量,以及风光混合MPPT技术的研究提供理论参考。
Based on the physical model, output characteristic and Maximum Power Point Tracking （MPPT） principle of photovoltaic module and wind turbine, the generic simulation models and MPPT circuit models for both were developed under Matlab/simulink environment. The variable step disturbance control algorithm applied to both photovoltaic array and wind turbine was proposed on the basis of summing up kinds of MPPT algorithms. Computer simulations and analysis to the algorithm were carried out by using the models established above. The simulation curves verify the correctness of these models and the good performance of the algorithm. The model and MPPT algorithm can be applied for dynamical simulation of wind-solar complementary power generation system. The results provide references for improving the energy utilization efficiency and power supply quality of the small scale wind-solar complementary power generation system, and the research on mixed maximum power tracking technology.
