UPS蓄电池选型对风电机组运行稳定的影响探讨

Discussion on the Influence of UPS Battery Selection on the Operation Stability of Wind Turbine

风力发电机组电控系统中的UPS蓄电池能在电网突发失电情况时将必要的电源提供给电控系统,确保机组能尽快实施应急措施。同时,UPS蓄电池也发挥着一定的稳压作用,但因该作用并不太突出,设计人员在设计中仅对续航需要的容量予以了充分考虑,而对稳压需要的容量考虑不足。在阐述UPS蓄电池分类的基础上,探讨了风电机组运行受UPS蓄电池选型影响后产生的问题,并研究了针对性的解决措施,以供参考与借鉴。

The UPS battery in the electric control system of wind turbine can provide the necessary power supply to the electric control system when the power grid suddenly loses power,so as to ensure that the unit can implement the emergency measures as soon as possible.At the same time,UPS battery also plays a role in stabilizing voltage,but because the role is not so prominent,the designers only fully consider the capacity required for endurance in the design,but not enough for the capacity required for stabilizing voltage.On the basis of describing the classification of UPS battery,this paper discusses the influence of UPS battery selection in the operation of wind turbine,and studies the corresponding solutions for reference.
