一种能自适应识别母线运行方式的备自投装置应用探讨

Discussion and application of an automatic bus transfer device of adaptive recognition bus operation mode

本文介绍了一种220kV备自投装置,列出了母联备自投和线路备自投的充电条件及起动条件。以220kV逸仙变电站为例,指出该备自投装置在双母线单分段接线的变电站应用中存在的问题,并提出了三种解决方案,分析了各自的优缺点,最后指出通过第三种方案改进的备自投装置能自适应识别双母单分段母线运行方式,实现母联备自投和线路备自投之间的自动切换,提高了备自投装置的灵活性、适应性和可靠性。

Introduced a 220kV automatic bus transfer device,listing Thecharging conditions and starting condition-sof automatic bus transfer equipment of bus-bar coupling and line.Take Yixian 220kV substation for example,indi-cating that the problems existing in the device considering the Duplicatebus Singular-segmentation substation,and proposes three solutions to this problem,analyzes their advantages and disadvantages.Finally,it is pointed out that through the three kinds of schemes to improve the automatic bus transfer device can adaptive identification of connection of the Duplicate-bus Singular-segmentation,the parent joint preparation from the cast and line by self investment between automatic switching,improve the automatic bus transfer device of flexibility,adaptability and reliability.
