风机备用电池组管理与健康状态监测的研究

在风机中,后备电池起着保护风机在电网出现故障时及时顺桨进而保护风机叶片的作用。而后备电池剩余电量以及健康状态更是直接影响到保护动作是否能正常地完成。为了保证后备电供电的可靠性和连续性,必须对备用电池进行在线观测与剩余电量预测评估。针对其特殊的工作条件及状态,提出可以精确反映当前风机后备电池剩余电量与健康状态的检测方法。

The research of management and health monitoring of Wind turbine backup batteries

In the power grid failure, backup batteries play the role of feathering timely and protecting wind turbine blades. The remaining power of backup batteries is a direct impact to the protection whether the action is able to complete normally as well as health status. In order to ensure the reliability and continuity of backup batteries, it must be observed online and forecast evaluation of remaining power. According to special working conditions and status,this paper proposed reflecting the current remaining power of backup batteries and detection methods of health status accurately.
