AI Technical Summary

Technical Problem

Existing technologies have low reliability in monitoring and maintenance scenarios involving aging equipment or collaborative monitoring of multiple power distribution room nodes. They are unable to accurately identify progressive abnormal data and regional power supply anomalies. Furthermore, the lack of data collaboration mechanisms in distributed deployment scenarios with multiple power distribution rooms increases the risk of missed detections.

Method used

By establishing a communication network between various power distribution rooms, a time series feature extraction model and a neural network fusion operation prediction model are constructed to achieve short-term and long-term predictions. Combined with multi-node data cross-validation and a distributed computing architecture, the aging feature weights are dynamically updated to conduct collaborative analysis of the aging status of multi-node devices. Furthermore, adjacent nodes assist in handling computing and transmission bottlenecks, thereby optimizing the scheduling of operation and maintenance resources and data transmission.

Benefits of technology

It improves the accuracy and processing speed of abnormal data detection, reduces the misjudgment rate and decision-making error rate, enhances operation and maintenance efficiency and fault handling efficiency, and meets the real-time early warning needs of the power distribution network.

Abstract

The invention belongs to the field of centralized control of power distribution stations, and particularly relates to a centralized control system and method of an intelligent power distribution station. A centralized control method of a power distribution intelligent station comprises the following steps: S10, establishing a communication network between each power distribution room node and a centralized control center according to a physical position relationship among power distribution rooms, and collecting operation data of devices in each unit in the power distribution rooms by using the power distribution room nodes; and S20, each power distribution room establishes an operation prediction model based on the local historical operation data, and the power distribution room nodes input the currently collected operation data into the operation prediction model to calculate the operation data after the preset short-term time and the preset long-term time as short-term prediction data and long-term prediction data. According to the scheme, the accuracy of abnormal data detection and prediction is improved, and the problem of low monitoring operation and maintenance reliability in a device aging or multi-power distribution room node cooperative monitoring scene in the prior art is solved; and the operation speed of detection and prediction is improved.
