The invention discloses an integrated support system and method for management and control of a power distribution network. A data layer comprises a data access processing unit for integrating and standardizing the collected data associated with the distribution network according to the common information model to form the pattern data, the historical data and the document data, and store respectively in the relational database, a sequential database and a distribution database. A service layer comprises a digital simulation model, a distribution terminal detection model and a distribution automation master station system test model called by an application layer, and the service layer realizes data interaction of all distribution models and assessing control of distribution equipment by equipment detection and matching and object accessing middleware/distributed file accessing middleware. The application layer comprises a distribution network operation analysis unit, a distribution network terminal detection unit and a distribution automation main station system detection unit, wherein the distribution network operation analysis unit calls a digital simulation model and uses a distribution network digital simulation algorithm to analyze the current network running states by combining with the distribution network related information in the data layer.
