| 摘 要： | 针对目前风力发电系统中储能装置(蓄电池)寿命短、充放电效率低的问题,提出采用飞轮电池作为储能装置的方案,分析了飞轮电池的d-q模型及其充放电控制策略。在飞轮电池充电控制过程中,采用基于转子磁场定向的矢量控制策略;在放电控制过程中,采用以直流母线电压为控制对象的控制策略。仿真结果表明,采用飞轮电池作为离网型风力发电系统的能量缓冲装置,能够有效稳定离网型风力发电系统的直流母线电压,提高其电能质量和稳定性。

| Abstract: | In allusion to problems of short life,low efficiency of charge and discharge of current energy storage device(battery) in wind power generation system,the paper proposed a schame of taking flywheel battery as the energy storage device,analyzed d-q model and charge and discharge control strategy of flywheel battery.Vector control strategy based on rotor field orientation is adopted in charge control,and the control strategy with DC bus voltage as control object is adopted in discharge control.The simulation results showed that using flywheel battery as energy buffer of off-grid wind power generation system can effectively stabilize the DC bus voltage and improve power quality and stability. |
