[0002] At present, there is a large amount of real-time information that has not been well utilized in terms of power grid topology connection, substation voltage loss, loss of user numbers, and supply load reduction data. For these real-time data of power grid operation, dispatchers cannot grasp them in time or accurately. The mastery of the operation of these power grids mainly depends on the manual experience of dispatchers or manual statistics afterwards, which can neither achieve real-time monitoring and calculation, but also spend a lot of manpower on post-event statistics

Embodiment
[0057] 1) Use substations, users, loads, and power grid topology connection data information as the basic data for model calculation.
[0058] 2) Using the topological connection relationship of the power grid, the data of voltage loss substations, loss of users, and supply load reduction are collected one by one, and reliable data that can be input into statistical algorithms for calculation are obtained.
[0059] 3) Input the data into the algorithm for calculation, and execute it from node 0 until each node meets the requirements. The intuitive way is to stop when each child node has no electrical connection relationship.
[0060] 4) Take the final calculation result of the node as the output to obtain the severity value of the grid hazard.

Description
technical field [0001] The invention relates to a technical method for assessing the severity of grid hazards, and is a method for calculating and evaluating the severity of grid hazards. Background technique [0002] At present, there is a large amount of real-time information that has not been well utilized in terms of power grid topology connection, substation voltage loss, loss of user numbers, and supply load reduction data. For these real-time data of power grid operation, dispatchers cannot grasp them in time or accurately. , The mastery of the operation of these power grids mainly depends on the manual experience of dispatchers or manual statistics after the event, which can neither achieve real-time monitoring and calculation, but also spend a lot of manpower on post-event statistics. Therefore, research and establish dedicated power grid topology connection, substation voltage loss, number of lost users, and supply load reduction data, in a real sense to realize th...
