Rapid restoration is vital for power system restoration to mitigate the consequences of major blackout. However, conventional textual restoration procedure hides the relations between conditions and the restoration actions, tends to slow down the restoration process and make the restoration harder. This paper proposed a visualization and support tool of restoration process with Hierarchical CPN (Color Petri Net). This tool graphically represents the relations among the system conditions and restoration activities, and gives explicit see of the status during the restoration process. The advantages of the proposed tool are (1) restoration areas or major restoration activities can be represented by sub-CPNs, this makes the entire CPN more manageable. (2) improve the communications between the restoration participants by sharing the restoration status on the CPN.
