摘要
针对变电站直流电源系统,应用并联技术、超级电容等前沿技术替代传统的蓄电池组和充电机作为应急电源产品。直流电源并联技术采用DC12 V/DC220 V或者DC12 V/DC110 V模块,配置12 V阀控密闭铅酸蓄电池、磷酸铁锂蓄电池、或者氢燃料蓄电池等,外挂超级电容模块,提出应急移动直流电源一整套解决方案。新技术的应用,大量减少了蓄电池使用量,起到环保作用,提高了电网的社会责任。
In DC power system of transformer substation,a new DC power system utilizing some forefront technology including parallel technology for power module and supercapacitor technology was used to replace the traditional DC power,including charger and battery pack,as emergency power system.The new DC power system was composed of DC12 V/DC220 V module or DC12 V/DC110 V module which configured 12 V valve regulated lead-acid battery or lithium iron phosphate battery or Ni-MH battery,and supercapacitor module in output terminal.A solution of emergency and moved DC power system was proposed with the above technologies.The adoption of this new technology can decrease sharply the quantity of valve regulated lead-acid battery,which can not only protect the environment,but also reflect the social responsibility of power grid.
