Relay protection for lines above 110kV
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 (overcurrent. In this paper, the main electric wiring mode of 110kV substation is selected, the structure of substation is determined, and then the main wiring diagram is drawn. According to the design and load of the primary electrical connection, select the maximum and minimum operating modes to calculate the. A relay protection solution has been explored for 110 kV high-load short-distance lines in this research, and its impact on the dynamic stability of the power system has been evaluated.
