摘要
风电变桨系统工作在特殊的运行环境中,常规电源已无法满足风机正常运行的需要。在此通过比较各种充电策略的优缺点,结合风电变桨后备电源的需要,提出针对风电变桨用密封阀控式铅酸蓄电池的优化充电策略;通过分析各种在线监测方案,设计出一种巧妙的单体电压巡检方案;最后设计出完整的风力发电变桨后备电源智能管理系统,并通过试验,验证了方案的可行性。
Placed in special environment, the conventional power supply has been unable to meet needs of the system of pitch master. Comparing advantages and disadvantages of the various charging strategies,an optimized charging strategy for the VRLA matching the need of battery in pitch master is introduced, a variety of online detection programs are analysed, it brings forward a smart module for voltage detecting for series - connected batteries. A complete intelligent management system for back- up power supply for the pith master is designed,and feasibility of the program through experiment is verified.
