The 750 kV power network gradually becomes the main power network in Northwest China. The general situation of the development of 750 kV power network in Northwest China are presented and its electrical characteristics are expounded; the network loss and network loss rate of Gansu power grid, the loss of 330 kV transmission lines and the loss of interprovincial tie line before and after putting 750 kV transmission line into operation are analyzed. Analysis results show that the network loss of Gansu power grid is evidently reduced by putting 750 kV transmission line into operation.
