The invention discloses a method for importing a distribution network graph model based on multi-task concurrency. The method comprises the following steps of enabling a plurality of clients to concurrently send registration requests and/or resource requests to a task main control server; enabling the task main control server to enter a registration state to receive the registration requests and/or the resource requests of the clients, registering the clients, and distributing resources for the clients; enabling the clients to read graph model data from the resources distributed by the task main control server to analyze, and sending analysis results to the task main control server; when the task main control server receives the analysis result of any client, entering a waiting state; after the analysis of all clients is completed and the analysis results are submitted, entering a processing state; enabling the task main control server to process the analysis results of the clients, and return the processing results to the corresponding client. The method is used for processing a plurality of concurrent distribution network graph model import tasks.
