| 摘 要： | 为了探索新型锂电池在变电站直流系统中的应用,根据110 kV标准变电站直流系统的配置,对事故负荷和事故持续时间等进行分析,考虑容量系数和可靠系数,并根据磷酸铁锂电池和三元锂电池的放电曲线特点,划分两种锂电池的有效工作区间,计算采用这两种锂电池作为110 kV变电站用直流电源时的电池配置,发现采用磷酸铁锂电池时,至少需要33串185 Ah的电池;采用三元锂电池时,则至少需要29串207 Ah的电池,所得结论大大证明了锂电池在变电站直流系统中应用的可靠性。

| 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. |
