摘　　要：以某地区两个年份的气象数据为依据,采用模拟和实验的方法,在建立离网风电-网电互补供电系统控制及运行模型的基础上,研究了蓄电池容量对3,k W互补供电系统性能的影响,结果表明:在保证风电/网电最小时间间隔切换的最小蓄电池容量情况下,随着蓄电池容量的增加,风能利用率和风电/网电供电时间比变化很小,但供电成本增加明显.The model for control and operation of off-grid wind power-grid power hybrid power supply system is established. On the basis of the two years＇ meteorological data in a certain area, the influence of battery capacity on 3 kW hybrid power system performance is researched with the methods of numerical simulation and experiment. The results show that as the minimum battery capacity for wind power/grid power minimum interval switch is guaranteed, the changes of the utilization rate of wind energy and the supply time ratio of the wind power to grid power are very small, but the cost of power supply significantly increases with the increase of battery capacity.
