摘要
蓄电池作为水电站中常用的储能设备,能够为电力系统提供稳定的备用电源,并满足水电站在电网停电或负荷波动时的供电需求。铅酸蓄电池以其容量大、寿命长、成本相对较低、充放电效率高和维护成本低等优点而在水电站得到广泛应用。然而,由于频繁的充放电,铅酸蓄电池易发生老化,所以当蓄电池出现开路故障时,会对整个水电站的电源安全构成严重威胁。因此文章基于目前较成熟的开路续流装置设计了一种新型铅酸蓄电池组装置,用于解决水电站铅酸蓄电池组开路故障问题。
As commonly used energy storage devices in hydroelectric power stations,Storage battery can provide stable backup power to the power system and meet the power supply requirements of hydroelectric power stations during grid outages or load fluctuations.Lead-acid batteries are widely applied in hydroelectric power stations due to their advantages of high capacity,long lifespan,relatively low cost,high charge-discharge efficiency,and low maintenance costs.However,due to frequent charge and discharge cycles,lead-acid batteries are prone to aging.When an open circuit fault occurs in the battery,it poses a severe threat to the overall power security of the hydroelectric power station.Therefore,based on the design of a novel open-circuit continuous current device that is relatively mature at present,this paper proposes a new assembly for lead-acid battery groups,aimed at addressing the open circuit fault issue in hydroelectric power station battery groups.
