Battery Capacity Options of the 110 kV Substation DC System Based on Lithium Iron Phosphate Battery

Lithium iron phosphate battery is a new kind of lithium ion battery with the ability of reliable operation in rigorous conditions,which is being widely concerned in many industries,especially being promoted in the electric car industry and energy storage industry.But it has not been applied in substation as a backup power.Taking a 110 kV substation as an example,combining with the rules of substation and characteristics of Lithium iron phosphate battery,the capacity calculation of lithium iron phosphate battery in substation power field is detailed introduced.
