Abstract:

Residual voltage lockup closing logic is introduced into current insitu feeder automation technology, which can quickly isolate faults. A residual voltage module is added to the feeder automation terminal to implement the residual voltage lockup function. Based on electricity distribution terminal products of a company, a residual voltage module scheme which combines software and hardware is completed. Itrealizes the protection logic of voltagecurrenttime feeder automation and meets the technical standards issued by State Grid Company Limited according to tests.
