AI Technical Summary

Technical Problem

In the current power grid dispatching system, the main and distribution network dispatching tasks are heavy, dispatchers have a large workload, and command efficiency is low. The traditional ordering method leads to the encroachment on maintenance schedules, making it difficult for dispatchers to extricate themselves from mechanical and manual labor and unable to focus on risk analysis and production control.

Method used

Design a three-level dispatch and command network interaction and collaboration system for the main and distribution networks, including data acquisition, data transmission, application services and display subsystems. Integrate OMS, D5000/distribution automation, grid-plant interaction and 'iStateGrid' data acquisition modules to realize real-time data acquisition and analysis, provide visualization display and mobile office functions, combine facial recognition and other technologies for identity authentication and security verification, and support intelligent maintenance and automated management.

Benefits of technology

It has improved the level of power grid dispatching and management, realized real-time tracking, collection and analysis of main and distribution network dispatching data, optimized dispatching and command efficiency, reduced construction and maintenance costs, strengthened intelligent error prevention capabilities, and improved the level of power grid dispatching and management.

Abstract

This invention provides a three-tiered dispatching and command network interaction and coordination system for the main grid and distribution network, comprising a data acquisition subsystem, a data transmission subsystem, an application service subsystem, and a display subsystem. The data acquisition subsystem includes an OMS data acquisition module, a D5000 / distribution automation data acquisition module, a grid-plant interaction data acquisition module, and an "iState Grid" data acquisition module. The data transmission subsystem encrypts and transmits data acquired from different data sources by the various modules of the data acquisition subsystem to the application service subsystem. The application service subsystem includes a main grid dispatching application unit and a distribution network dispatching application unit, used to analyze and process the received data according to their respective business needs, realizing the dispatching and command functions of the main grid and distribution network. The display subsystem presents the data processed by the application service subsystem in a visual manner, facilitating monitoring and decision-making by dispatchers. This invention can improve the command and management level of power grid dispatching.
