Extended data

A large power grid (combined power grid) is always formed by the development and interconnection of many sub-grids, so hierarchical structure is a major feature of power grid. General power network can be divided into transmission network, secondary transmission network, high voltage distribution network and low voltage distribution network.

Transmission network is generally composed of main power lines above 220kV, connecting large power plants, large-capacity users and adjacent sub-grids. The voltage of secondary transmission network is generally 1 10 ~ 220 kV. Connect to the power transmission network and the high-voltage distribution network. It is a regional network, connecting regional power plants and large users. Distribution network is a network that supplies power to medium and small users. 10~35kV is called high-voltage distribution network, and 10 ~ 35kV is called low-voltage distribution network.
