The invention discloses a processing method for distributed setting calculation models layered according to voltage levels. The processing method can achieve integrated application of power grids at all levels and can make rights and liabilities of users at all levels be clear. The method includes the steps that (1), servers are deployed for a high-level unit and a low-level unit respectively, and a public server is deployed for the high-level unit; (2), the distributed setting calculation models, layered according to the voltage levels, of the high-level unit and the low-level unit are each deployed according to the voltage levels and the adjusting and managing range; (3), boundary branch parameters in the distributed setting calculation models are set; (4), the boundary branch parameters which belong to the low-level unit are automatically uploaded to the public server; (5), boundary branch parameters which belong to other low-level units are automatically obtained from the public server.
