摘要
级联电池储能系统能实现6~35 kV电压等级直接并网,有利于实现电池储能的大容量化,在电网中有良好的应用前景。但大容量高压级联电池储能系统体积大,分布参数的影响突出。深入分析分布电容对电池管理系统测量电路和通信电路的影响机理,并提出消除分布电容影响的方法和措施。
Cascaded battery energy storage system is suitable for 6~35 kV voltage level direct grid connection,which is conducive to the large capacity of battery energy storage,and has a good application prospect in power grid.However,the large-capacity and high-voltage cascade battery energy storage system is large in size,and the influence of the distribution parameters is prominent.In this paper,the influence mechanism of distributed capacitance on the measurement circuit and communication circuit of battery management system is analyzed,and the methodsand measures to eliminate the influence of distributed capacitance are put forward.
