An Auxiliary Decision-Making System for Rapid Power Ratio in Regional Power Grids

Abstract

The invention provides a quick cutting-off and rationing power assistant decision-making system of a regional power grid. The quick cutting-off and rationing power assistant decision-making system of the regional power grid is based on a scheduling technical support system of a regional smart power grid, and comprises a model management module (1), a sequence table processing module (2), a cutting-off circuit load real-time monitoring module (3), a man-computer interaction module (4), a cutting-off circuit operating module (5) and a grid operation stable state monitoring module (6), wherein a corresponding relationship table is established in the sequence table processing module (2) so as to form a cutting-off circuit operating table of cutting-off circuit equipment with loads cut off. The cutting-off circuit load real-time monitoring module (3) receives real-time monitoring information of cutting-off circuit loads, the man-computer interaction module (4) selects a cutting-off circuit strategy set and manually adjusts the cutting-off circuit operating table to obtain a breaker which corresponds to the cutting-off circuit equipment in the cutting-off circuit operating table according to a corresponding relation table, and the cutting-off circuit operating module (5) remotely operates sequence of a breaker switch. Manual operation steps and manual computation are reduced, operating time for cutting-off and rationing power is greatly reduced, and operating accuracy is improved.

Description

technical field [0001] The invention relates to the field of electric power system dispatching automation, in particular to an auxiliary decision-making system for rapid power rationing in regional power grids. Background technique [0002] Rapid power rationing in regional power grids means that in the event of an accident in the power grid or an imbalance between power supply and demand, the provincial dispatcher issues an order to the prefecture-level dispatcher for the capacity of the route. Or the sequence table of the accident pulling line, manually check and arrange the pulling line combination according to the real-time data, and the power substation monitoring personnel will pull the power supply line circuit breaker to stop the power supply forcibly. During the process of issuing the removal order, the dispatcher needs to manually check SCADA (Supervisory Control And Data Acquisition, Data Acquisition and Supervisory Control) system telemetry and telesignaling data...

AI Technical Summary

Problems solved by technology

[0004] 1. The degree of automation is low, the management process is lacking, and the manual operation is the main method. The records of the pull and recovery time of the two external lines, the load of the pull, and the statistics of the power loss all need to be manually processed by the dispatcher, which greatly increases the dispatching time. staff workload

[0005] 2. There are many intermediate links. For example, manual checking and calculation are required for arranging lines. The issued instructions need to correspond to different monitoring or substation operators one by one. The entire execution process takes a long time and cannot quickly control the load.

[0006] 3. Manual wiring is complex and lacks auxiliary decision-making means. After receiving the task, the ground dispatching dispatcher completely relies on manual analysis. In the selection of the pulling operation, it needs to be determined by comparing the pull-limiting sequence table and the current real-time operation status of the current grid load. Effective auxiliary decision-making means, resulting in inefficient decision-making, and the possibility of mis-scheduling and misoperation

[0007] 4. The efficiency of road pulling is low. When multi-way road pulling is carried out, there is a lack of effective closed-loop control means and measures. The efficiency of road pulling is low, and even the phenomenon of not being able to pull roads in time can not respond to dispatching needs in a timely manner, which affects the safe and stable operation of the power grid. At present, the dispatchers in various regions have not provided effective management and technical means for power rationing
