Automatic line pulling control method based on provincial and regional integration

Abstract

The invention discloses an automatic line pulling control method based on provincial and regional integration, which comprises the steps of: sending a power cutting-off and limiting target command to a regional dispatcher by a provincial dispatcher; automatically receiving a task and sending an alarm by the regional dispatcher, and starting a task processing client; looking up task information by the regional dispatcher through the client and sending a confirming message to the provincial dispatcher; through a power cutting-off and limiting assistant decision client, selecting a power cutting-off and limiting sequence table and a line pulling strategy, combining real time remote signaling and telemetering information of an EMS (Enhanced Message Service) system to automatically generate the line pulling strategy of the target task; and sending a remote control command to a remote RTU (Remote Terminal Unit) terminal through a batch remote control technology. The method provided by the invention realizes integrated close loop operation for cutting off and limiting the power, can cut off the target line in real time efficiently, and powerfully guarantees safe and stable operation of the power grid.

Description

[0001] An automatic road pulling control method based on provincial and land integration. technical field [0002] The invention belongs to the field of electric power system dispatching automation, and relates to an automatic road pulling control method based on provincial and land integration. Background technique [0003] Power curtailment means that when an accident occurs in the power grid or the power supply and demand are unbalanced, the provincial dispatcher issues a road capacity instruction to the prefecture-level dispatcher. The sequence table is manually checked and arranged according to the real-time data, and the circuit breaker of the power supply line is opened by the substation monitoring personnel to forcibly stop the power supply. [0004] The traditional power cut operation mainly relies on the telephone method. The dispatcher of the provincial dispatching center notifies the prefecture-level dispatching center to issue the load limit task target. The pr...

AI Technical Summary

Problems solved by technology

[0005]1. Low degree of automation and lack of process management

Mainly manual operation, information exchange between provinces and regions is difficult. In addition, the records of route pulling and recovery time, the load of the route, and the statistics of power loss all need to be manually processed by the dispatcher, which greatly increases the dispatcher's workload. workload

[0006]2. There are many intermediate links

If the arrangement of lines requires manual checking and calculation, the issued instructions need to be executed one by one corresponding to different monitoring or substation operators. The entire execution process takes a long time and cannot achieve rapid load control.

[0007]3. Manual wiring is complicated and lacks auxiliary decision-making means

After receiving the task, the ground dispatching dispatcher completely relies on manual analysis. The operation selection of the route needs to be determined according to the pull-limit sequence table and the real-time operation status of the current power grid load. The lack of effective auxiliary decision-making means leads to inefficient decision-making, and There is a possibility of mis-scheduling and misoperation

[0008]4. Low efficiency of road pulling

When carrying out multiple road pulls, there is a lack of effective closed-loop control means and measures, the efficiency of the pull is low, and even the phenomenon of not being able to pull the roads in time occurs, and it is impossible to respond to the needs of provincial dispatching in a timely manner, which affects the safe and stable operation of the power grid. Dispatching in various regions At present, there is no effective management and technical means for power rationing
