Research on Multi-module Collaborative Blocking Technology of Hydropower Station Battery Pack
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.
