After flow and transient stability calculating of the 330kV grid, we got the over-load and hazard lines set. Then we gained the redundant network needed to be built according to the increasing power supply and load in 2010. Adopting regradation step-by-step algorithm by which we can improve the calculation efficiency , we compared the validity of every line, deleted lines with low validity until no redundant line is in the network. At last we got the target network framework adopting the improved ant colony algorithm. Flow distribution, construction investment assessment and target framework of Gansu long-term planning all be considered, from the viewpoint of to be economic and reliability the feasibility of the improved ant colony algorithm is discussed.
