Dispatching automation system is the nerve center of power grid. When using the system, it usually needs grid model diagrams, such as plant station wiring diagram, flow calculation diagram, etc. In addition, the model files are used for grid monitor, dispatching analysis, etc. Thence before use, these files need to be approved strictly for ensuring the security of the running power grid system. This paper briefly describes the dispatching automation master system iES600Pro of Integrated Electronic Systems Lab Co. Ltd. (iESLab). Moreover, it proposes a system optimization scheme based on workflow technology, thus the system can implement complete approval process of model files. The process is flexible, convenient and customizable. Furthermore, it presents the implementation of scheme including the architecture of system after the optimization, the description of interfaces between system components, the design of business data table, a sample of approval process, and finally the testing platform and results. The results show that the proposed scheme improves the system function and approval efficiency. It is more conducive to the security of grid dispatching.
