This paper proposes a multifractal least squares support vector machine detrended fluctuation analysis (MF-LSSVM-DFA) model. The system is an extension of the traditional MF-DFA To address potential overfitting or underfitting caused by fixed-order polynomial fitting in MF-DFA, LSSVM employed as superior alternative for fitting. approach enhances model accuracy and adaptability, ensuring more reliable results. We utilize p to construct multiplicative cascade time series evaluate performance...
The transmission line is an important channel for the electric energy in power system. Whether stable of related to key issues such as people's livelihood and industry, so it great significance evaluate operation status line. Aiming at shortcomings current evaluation methods lines, this paper proposes a comprehensive method lines based on improved combination weighting model. By constructing indication system standards specifications, comprehensively considering subjective weights objective...

Abstract For overheating defects of power equipment, the use infrared technology is widely popular at present, which less costly and more efficient than traditional manual detection thermal equipment. However, images have nature concentrated intensity low contrast, picture segmentation has always been a difficult point. This paper proposes combination K-mean clustering improved region growing algorithm, compared with solves need to manually select seed point produce uneven gray scale...
<title>Abstract</title> A hybrid prediction algorithm based on hierarchical clustering and Beluga Whale Optimization (BWO) algorithm, Bi-LSTM network is proposed for the high voltage transmission lines so as to face inclination angle of pole towers caused by different weather reasons in future take safety protection measures. Using dataset historical tower tilt with a timestamp, it verified example that short-term BWO-Bi-LSTM able predict under any weather, which overcomes limitations...
Ensuring the safety of transmission line towers is vital for human safety, power supply, economic development, and environmental protection. This study specifically examines how temperature affects tower inclination. Multifractal detrended cross-correlation analysis (MF-DCCA) a combination multifractal fluctuation (MF-DFA) DCCA that reveals features two cross-correlated non-stationary signals. paper adopts MF-DCCA tool to investigate cross-correlations between internal an inclination sensor...
Abstract In order to study the effect of seasonal permafrost on soil resistivity, firstly, resistivity influencing factors were analysed, conductivity model was established, and effects number freeze-thaw cycles at different depths analysed through simulated experimental measurements. The results show that cycle will lead structure damage, internal loosening, current conduction is blocked, increases; with rise in cycles, gradually solidified, enhanced, decreases tends be stabilised; beyond...
This Frozen soil refers to or rock containing ice, whose temperature is lower than its freezing temperature. Different regions and different geological conditions influence the engineering problems of frozen regions. The tower foundation a very important part construction transmission line plays decisive role in whole project. Frost heaving mainly fact that water reaches below-freezing freezes into ice during process, resulting volume increase tangential frost force, instability foundation....
The ultrasonic bird driving device adopts PLC control technology, which makes the keep standard operation state in period of time without working, resulting energy waste and reduced service life equipment. In view above problems, this paper studies frequency technology based on perception. multi-dimensional perception algorithm lgmad is used to process data collected by detector, so as obtain running device. conversion strategy phased start-up established, realized combining PID fuzzy...
The uneven settlement and horizontal displacement of the transmission line tower foundation may lead to overall tilt collapse accidents. In order obtain information foundation, method displacement. According engineering practice, proposed can monitor foundation.
With the development of economy and improvement electricity demand, overhead lines power facilities such as substations are being built rapidly. Due to influence temperature, soil quality, construction, other factors, importance basic differential settlement control has become increasingly prominent. To ensure safe service these equipment during operation period, author must deeply study foundation under long-term load action. This paper considers essential characteristics damage around...
