摘　　要：风机变桨系统中阀控式铅酸蓄电池应用最广泛,但是应用中逐渐体现这种电池的高成本、故障多、寿命短等缺陷。本文首先对影响铅酸蓄电池使用寿命的主要因素进行分析,在此基础上提出一种其他行业应用较为广泛的技术,半导体制冷技术引用到风电变桨系统中,通过合理的温度控制,变桨蓄电池的使用寿命完全可达到5~6年,可在风电机组寿命周期内减少更换次数及故障频率。Valve Regulated Lead Batteries are used mostly as backup power of the wind turbine pitch system in domestic,but in the process of application,this kind of batteries has the high cost、many faults、short service life and other defects.This paper analyzes the main factors affecting service life of batteries,based on the analyzing these factors,this paper presents a technology widely used in other industries:semiconductor refrigeration can be used in the wind turbine pitch system,through reasonable temperature control,can prolong the service life of the batteries and reduce the faults of wind turbine.
