摘　　要：本文对风力发电系统中的蓄电池组数学模型进行了研究,基于MATLAB/Simulink平台建立了蓄电池组的仿真模型并进行了改进;对蓄电池组充放电控制算法进行了理论研究和比较,提出了三段恒流充电控制和基于安培小时法的放电深度控制的蓄电池组充放电控制策略并进行了算法设计;在搭建完风力发电系统整体模型的基础上进行了仿真研究,验证了本文所搭建仿真模型的正确性以及所设计控制算法的正确性和有效性。In this paper, a model of the batteries in wind power system is studied, whose simulation model is built up and improved based on the MATLAB/Simulink platform. After the theoretical analysis and the comparison of current battery charge and discharge control algorithms, the three-phase constant-current battery charge and discharge depth control strategy is presented and algorithmic designed. Based on constructing the whole model of the wind power generation system, simulation is finally executed to verify not only the validity of the simulation model but also the correctness and effectiveness of the control algorithms.
