摘要： 随着发电站和变电站自动化程度的提高，为变电站和发电站提供通讯、调度、控制、照明等动力的直流系统显得尤为重要，直流系统为电力控制和操作提供重要的电力保障，是电力系统控制、保护的基本保障。如果直流电源系统供电不可靠失电，将导致变电站所有通讯、调度、控制、保护、照明处于瘫痪状态，无法保证变电站的安全稳定运行，在变电站站用电源事故停电情况下，整个电站失去可控性和保护，极易造成电网事故，给电网安全稳定运行带来潜在风险。直流电源是变电站的心脏，电池是电源的最后屏障，目前国网公司暂无磷酸铁锂电池的生产能力。

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
