Gansu Electric Power Commissions Northwests First Out-of-Province Backup Dispatch Exchange System

It is reported that the Northwest Division of the State Grid, as the Gansu Power's out-of-province backup dispatching place, undertakes the annual switchover rehearsal of the main and backup dispatching of Gansu Power Grid. In the process of switching exercise in previous years, as the State Grid Gansu Power has no independent dispatching exchange system in the northwest division, the dispatching telephone number is assigned by the dispatching switch of the northwest division, which makes the main and standby dispatching telephone numbers inconsistent and cannot realize "double machine preparation and resonance with the same number", and if the main dispatcher encounters an unexpected situation and cannot perform the dispatching function normally If the main dispatcher cannot perform the dispatching function normally, the backup dispatching exchange system cannot be activated in time, which brings great risk and hidden danger for the safety dispatching of Gansu power grid.

"Relying on the strong support of the northwest backbone communication network can further enhance the safe and stable operation level of Gansu power grid dispatching and greatly improve the risk resistance of Gansu power grid dispatching." State Grid Gansu Power Information and Communication Company Communication Center Director Ma Le told us that Gansu has a long and narrow geographical area, complex and diverse landscapes, geological disasters are frequent in the eastern part of the river, the western part of the river is more remote and difficult to access. Especially during the "new crown" epidemic, Gansu power to improve the safety and reliability of power grid dispatching comprehensive analysis and research, off-site site to build equipment dispatching exchange system to become the optimal solution.

For this reason, the company attaches great importance to the construction work of the off-site dispatching exchange system, and actively plans to carry out the construction work of the off-site dispatching exchange based on the construction goal of "being able to perform in times of peace and use in times of war" and the model of "off-site disaster tolerance and double machines with the same number". The construction work is carried out on the basis of "off-site disaster tolerance and double machines with the same number". Relying on the strong support of the northwest backbone communication network, through the network with Gansu provincial transfer station and 750kV Baiyin change provincial dispatching exchange convergence center station, the main and backup dispatching exchange system of Gansu power is highly integrated into one system, forming a "pyramid" type structure of the provincial convergence center station, out-of-province backup transfer and northwest network transfer, realizing the dispatching exchange system of power grid. The system has achieved "zero downtime" for off-site disaster recovery, further optimized the dispatching and switching network structure and enriched the routing methods among core sites, which greatly enhanced the safe and stable operation level of Gansu power dispatching and switching network.

"Once there is a disaster or epidemic in Gansu that affects the safe dispatch of the power grid, we can switch the system at the first time to ensure the safe and stable operation of Gansu power grid dispatch at all times." Ma Le introduced.

Next, State Grid Gansu Power will establish and improve the daily management system and emergency activation mechanism of the out-of-province backup dispatching exchange system, strengthen the equipment operation monitoring level, organize and carry out emergency drills for the main backup dispatching exchange routing switching, effectively play the disaster tolerance capacity of the out-of-province backup dispatching exchange system in Gansu, and at the same time, according to the requirements of the special upgrading work program of the northwest power dispatching exchange, continuously improve the Gansu power dispatching exchange network frame At the same time, according to the requirements of the special upgrading work plan of Northwest Electricity Dispatching Switching, we will continue to improve the network structure of Gansu Electricity Dispatching Switching Network and continuously promote the operation of dispatching switch network to a new level.
