Abstract: How to quickly generate a black-start path and system restoration scheme has always been one of the urgent problems needing to be solved in emergency response of power system. This paper develops an assistant decision-making system for black-start path generation and system restoration scheme based on 3D visualization technology. Firstly, The overall framework architecture of the system is introduced; And then, the module functions and its implementation methods of the system are further described in detail, including data base, graph platform, and algorithm library that is composed of initial path generation, path check and assessment, and system restoration; Finally, an actual power system is used to verify the effectiveness and correctness of the designed system. The results show that the designed system has a perfect integrated graph-model system formed by graphical interface, database system and algorithm library, which has the advantages of reasonable configuration, complete functions and convenient for use.

Key words: black-start scheme, system restoration, power grid emergency, graph-model integration, dispatching operation
