110 kV变电站直流系统锂电池容量计算
Calculation on Capacity of Lithium Battery of Direct Current System in 1 10 kV Substation
摘要
Abstract
For studying application of new type lithium battery in direct current system in 1 1 0 kV substation,this paper ana-lyzes emergency load and duration according to configuration of direct current system in standard 1 1 0 kV substation.Meanwhile,it considers capacity coefficient and reliable coefficient.According to characteristics of discharging curves of Fe battery and ternary lithium battery,effective workspaces of these two lithium batteries were marked off.By taking these two lithium batteries as battery configuration for direct current power source in 1 1 0 kV substation,calculation was conducted and the result showed that when using Fe battery,33 series of 185 Ah battery were at least needed,while when using ternary lithium battery,29 series of 207 Ah battery were at least needed.Conclusion proves application reliability of lithium battery in direct current system in substation.关键词
