传统备用电源自投装置采用老式继电器逻辑组合,具有二次接线复杂、功能僵化等缺点,尤其在变电站一次系统运行方式发生改变时,容易造成误动作。基于中海化学二期110kV变电站电源备自投装置,利用微机技术的应用实践对一种新型微机备用电源自投装置设计方案及逻辑框图进行了分析,此备自投装置通过软件对不同主接线方式自动进行模式识别,可改善供电运行方式的灵活性,提高供电的安全性、可靠性。
The traditional backup power supply self-throwing device adopts the logic combination of the old-style relays, which has the disadvantages of complex secondary wiring and rigid functions. Especially when the operation mode of a substation system is changed once, it is easy to cause malfunction. Based on the application of microcomputer technology, this paper analyzes the design scheme and logic block diagram of a new microcomputer stand-by power supply self-throwing device. Based on the software, Automatic pattern recognition can improve the flexibility of the power supply mode of operation and improve the safety and reliability of the power supply.
