Design of 110kV Relay Protection for State Grid

The 110 and 220 kV lines of the main grid are protected by means of two primary protection schemes (two distance relays or a distance and a differential line relay) or a primary protection relay (distance relay) and a backup protection relay . The 110 and 220 kV lines of the main grid are protected by means of two primary protection schemes (two distance...
