For the selection of site and type of power distribution terminals, the 9-state transition model considering communication link failure is firstly proposed. Secondly, the link failure of different communication networking modes of power distribution terminals without tele-control function and power distribution terminals with tele-control function is considered. Under the condition of economic loss caused by error/rejection failure, a calculation method of integrated power outage loss considering the influence of communication reliability is proposed, and together with the construction cost of distribution terminal, the objective function is used for the selection. Then, combined with the theory of node importance and considering the dual constraints of power supply reliability and investment cost, a staged selection strategy of site and type for power distribution terminals is proposed. Results of the example show that the proposed staged site and type selection planning method can obtain a feasible solution that satisfies the constraints stably and reliably. In the scenario that the traditional intelligent algorithm based integrated planning method falls into the local optimal solution or even unable to obtain the feasible solution, the proposed staged planning method can still guarantee the quality of the solution.
