一起110kV电力系统自动装置的分析与整改

Analysis and rectification 110 kV substation standby behavior

在现代电力系统中,为了提高供电可靠性、节省设备投资、简化电力系统接线及继电保护配置、限制短路电流、提高母线残余电压,广泛采用了备自投装置。备自投装置是当工作电源因故障被断开以后,能自动迅速的将备用电源或备用设备投入工作,使用户不至于停电的一种装置。这是一种提高对用户不间断供电的经济而又有效的重要技术措施之一。为此要求备自投装置应可靠正确动作,才能发挥其应有的提高电力系统可靠性的作用。

In the modern power system,in order to improve the reliability of power supply,saving equipment investment,simplify the power system wiring and relay protection configuration,limiting the short-circuit current,improving the bus residual voltage,automatic switching device widely used.Automatic switching device is when the power supply due to failure is broken,can automatically and rapidly will standby power or standby equipment to work,the user not a device power outage.This is a one of the most important measures to improve the uninterrupted power supply for economic and effective.This should be the correct action selecting reliable automatic switching device,to play its due role in improving power system reliability.
