AI Technical Summary

Technical Problem

The existing power supply regulation strategies for environmentally friendly gas ring main units lack insulation risk prediction and proactive defense measures based on historical degradation processes, making it difficult to identify the evolution trend of insulation risks. Furthermore, the power supply regulation measures are not targeted enough, which can easily lead to an exacerbation of insulation risks.

Method used

By acquiring historical information of environmentally friendly gas ring main units, an insulation degradation historical sample library is established. This data is then acquired and converted into state sequences in real time. Similar degradation matching and margin prediction are performed to generate power supply stability adjustment commands. Active defense measures are implemented when the insulation margin is below the threshold.

Benefits of technology

It enables proactive assessment and improved accuracy of insulation risks, ensuring power supply stability and insulation safety. By taking proactive preventative measures, it can reduce load or adjust power supply paths in a timely manner, preventing the expansion of insulation risks and enhancing operational reliability.

Abstract

This invention discloses an intelligent control method for environmentally friendly gas ring main units (RNBs) used for power supply stability regulation, belonging to the field of power equipment control technology. It includes historical information acquisition: obtaining historical information such as electrical operating parameters, gas insulation status parameters, and insulation margin from the past operation of the environmentally friendly gas RNB. This invention acquires historical information from the past operation of the environmentally friendly gas RNB, extracts historical degradation fragments, establishes a historical insulation degradation sample library, and then converts the real-time state of the target environmentally friendly gas RNB into a state sequence that can characterize the current insulation change trend. This sequence is then matched with the historical degradation fragments to predict the insulation margin in future periods. Compared to relying solely on real-time monitoring values ​​for threshold alarms, this invention can identify the current stage of insulation evolution from historical degradation patterns, obtain the development trend of insulation risk in advance, and improve the foresight and accuracy of insulation status assessment.
