Abstract

Abstract: With the improvement of automation degree of power station and substation, it is very important to provide DC power system for communication, dispatch, control and lighting of substation and substation. DC system provides important power guarantee for power control and operation, and is the basic guarantee for power system control and protection. If the DC power supply system is unreliable power loss, it will lead to the substation all communication, dispatch, control, protection, lighting in a state of paralysis, can not guarantee the safe and stable operation of the substation, in the substation substation power supply accident blackout, the whole power station loses controllability and protection, it is very easy to cause power grid accidents, power supply. Safe and stable operation of network brings potential risks. DC power supply is the heart of substation, battery is the last barrier of power supply, the current state grid company has no production capacity of lithium iron phosphate battery.

Key words: substation, lithium iron phosphate, DC system
