Abstract: In the process of innovating and upgrading the new power system, we should attach great importance to the emergency response of large-area power failure. Should be based on the function and characteristics of the source, the power grid, risk analysis and classification, with different areas, provinces and counties, the preparation of the corresponding large blackout emergency plan, drill scheme, drill scripts, and the revision and practice, and set up practice subjects and scenarios, such as the source of the scenery water complementary pumped energy storage power grid scenery power grid again, giant hydropower unit earthquake column shutdown and system stability device stability control frequency and voltage, uhv line debris flow tower bipolar lock, etc. The government and the power sector of the large area blackout emergency plan cannot be replaced by each other. This paper puts forward 7 specific problems when compiling and implementing the emergency plan for large area power failure. Finally, the paper combines the upcoming UHV integrated power grid, and it is suggested to take precautions and pay attention to the emergency response of large-area power failure.
