| Abstract: | Based on logic analysis of standby power automatic switching device for 110kV substations equipped with inter - bridge connection, this thesis discusses the influence of main transformer protection operation on standby power automatic switching device operation under complete and incomplete inter -bridge connection. And the coordination scheme between main transformer protection and standby power automatic switching device in ll0kV inter -bridge connection substations is proposed, which makes standby power automatic switching device more adaptive to substation operation mode and the choice of the lock of automatic switching device by main transformer protection. |
