Abstract: In view of the problems that the lack of unified data source，unified information standard，unified

support platform for common services caused by multi system parallel in each stage of power grid enterprise project

management，and resource and information "isolated island" caused by "chimney" system architecture，which

cannot support project decision effectively，an intelligent system architecture of power grid enterprise project

management based on lock chain，big data，heterogeneous cloud and distributed message queue was proposed.

Firstly，heterogeneous cloud platform，data platform，project management platform and multi-modality application were analyzed. Then，the core architecture of the intelligent system was designed from the perspective of business，data，technical and deployment architecture. Finally，the proposed intelligent system architecture was implemented by Project Reserve Center of State Grid Corporation of China. The continuous transformation of power grid enterprises from process driven to data-driven can be promoted by the architecture，reference and basis for the

optimization of future project management mode can be provided.
