This exercise uses a combination of functional drills, combat drills and simulated drills:

Functional exercises focus on the effectiveness of emergency plans, emergency command coordination, the correctness of emergency response. After the event of a large-scale blackout event, the government emergency command organization member unit is mainly responsible for the "functional" unit of the emergency management, in the main venue using interactive integrated emergency training system platform to participate in joint exercises, according to the system virtual release disaster information Out of decision-making, command, carry out resource deployment, collaborative linkage disposal. Disaster information from the background push, do not use real staff and equipment, not on-site disposal, all decision-making instructions from the virtual role of virtual implementation.

Practical exercises, focusing on the emergency response team, emergency supplies and other resources to mobilize efficiency, organizational combat capability and emergency response capabilities. Through the live broadcast form to show the emergency disposal process, the use of real staff and equipment.

Simulation exercises, focusing on enhancing the emotional awareness of participating staff, to make up for the lack of functional exercise. On the part of the exercise time and venue constraints, can not be synchronized to carry out the actual exercise of the representative scene, to take pre-pre-recorded video, through the video display emergency treatment process.

Simulation scene

Affected by strong convective weather

Substation loss of large area power outages

During the period of overhaul and strong convective weather, the winds caused by moving winds such as moving trains and shorts of foreign bodies occurred, which resulted in the failure of North Grass Ⅰ, North Grass Ⅱ and Grass Feng Ⅰ Three 330-kilovolt transmission lines have trips, coincidence is not, Weihe power plant output can not maintain the marsh area of the isolated network operation, and the system solution, 330 kilovolt grassland 110 kilovolt busbar to stop, resulting under the jurisdiction of the 14 substation pressure , Eventually triggering a large area of power outages occurred. Many parts of Weiyang District of Xi'an are affected by power supply in some areas of Lianhu area. The power loss load is 21% of the load of Xi'an power grid before the accident, and it is prejudiced to constitute a large area blackout.

The municipal government immediately launched a large area of power failure event Ⅲ emergency response, co-ordinate the relevant departments, the unit to coordinate the disposal. Have started power, communications, health, law and order, fire, traffic, materials, publicity and other emergency plans. By taking measures to maintain law and order, fire and fire, command to ease the traffic, evacuation of trains, rescue the injured people, repair damaged power facilities, important users emergency power supply and other measures to jointly deal with large-scale blackout. After emergency treatment, all users to restore and reduce the load to recover more than 90% after the end of the emergency situation.

Subsequently, the affected area of the grid continued to expand, the fault trip led to the city's large-scale power outages, power supply units through the standby power supply automatically into the device, switch to standby power supply operation, but the accident still caused a lot of load loss. In this regard, the power supply units active coordination, by adjusting the power grid mode of operation for load transfer.

In accordance with the exercise design, power failure to urban transport, medical, communications and many other links have been affected to varying degrees, some important enterprises due to power outage and interruption, dangerous gas accumulation, security risks increased; communications operators found that power outages all The base stations have stopped the power supply, so the emergency commissioning of standby generators, but can not restore power supply, the relevant area of millions of users of the communication will be affected; many people have to power supply companies, news media inquiries related to the situation, District residents due to power outage caused by water interruption, the elevator outage; some residents began to buy candles, bottled water, public security and other departments continue to focus on social trends ... ...
