磷酸铁锂电池在变电站系统应用的可行性分析

Feasibility of applying ferric phosphate lithium cells to substation systems

就常规性能、温度特性、寿命特性、倍率放电性能,将铅酸电池和磷酸铁锂电池做了对比;从性能、购置成本、使用维护成本、安全性和废弃处理等方面分析了磷酸铁锂电池在变电站系统应用的可行性;从变电站系统发展的趋势:高度自动化和站用电源一体化,分析了磷酸铁锂电池将逐步替代铅酸电池成为主力二次备用电源的可能性。

The ferric phosphate lithium cell and the lead-acid cell were compared in the aspects on performance,temperature characteristics,life,and rate discharge performance.Also,the feasibility of applying the ferric phosphate lithium cell to the substation system was studied in relation to performance,purchase cost,utilization and maintenance cost,safety,and disposal treatment.Based on the development trend of the substation system,i.e.high-degree of automation and integration of service supply,the possibility of the ferric phosphate lithium cell in replacing the lead-acid cell as the main backup power supply for secondary equipment was analyzed.
