General grounding method of overhead ground wires adopted in Chinese 500-kV transmission lines is usually optical fiber composite wire (OPGW) grounded at each tower while common (CGW) insulated with one point grounded. Energy loss OPGW and high induced voltage CGW a problem to be concerned as its values control methods. Both field measurement ATP-EMTP simulation current single-circuit line are carried out this paper. Quantitative data energy show the urgent necessity reduce change wires. A...
Overhead line ice-shedding causes breakage and results in electrical faults occurring between transmission lines, which seriously affects the safe operation of power grid. In this paper, a risk assessment method for on 500 kV compact overhead lines is proposed. Two ratios were used to assess discharge mechanical failure line. A southern China was taken as an example, proposed carry out with ice thickness 15 mm, suppression effects different spacer arrangement schemes analyzed. The showed...
Slippery liquid-infused porous surfaces (SLIPS) have received growing attention as promising icephobic materials. In this study, SLIPS were prepared on aluminum alloys by combining anodization and infusion of common silicone oil. An with low ice-adhesion strength (6 kPa) was obtained optimizing the anodizing time parameters (10 min). addition, frosting process freezing water droplets as-prepared at −10 °C delayed for 2000 s 4800 s, respectively. Simultaneously, also exhibited excellent...
Visible and infrared images are essential for electrical inspection robots to detect equipment or components. Here how combine these two kinds of information is a critical problem. Image registration one the necessary processing procedures. While used in practice, traditional intensity-based feature-based methods appear many deficiencies such as low accuracy, reliability speed. In this paper, we propose an efficient method based on quadrilateral features equipment. Contour straight line...
Icing thickness parameter is the basic data for power sector to make decision icing accident prevention. In this paper, a transmission line measurement method proposed. It used photogrammetry realize parameters through integration of high resolution camera, laser range finder and inertial unit. Compared with traditional method, flexible effective supplement fixed detection terminal. And its accuracy guarantees reliability parameters.
This paper investigates the controlling factors of evolution debris flows along Jinjiang River, which is located in an active orogen. The River are threatening nomads and pastures, as well power station on river its workers. Remote sensing images, geological maps, field investigations were conducted to determine distribution lithologies, faults, flows. A total 82.2 km riverbank 108 flows, including 22 huge investigated. results indicate that primarily controlled by either faults or...
Long-term cold cause ice to build on transmission lines, making it risky for the electrical infrastructure work. There is a lack of methods quantitative detection overhead line insulators. In this article, we built system natural covering composite insulators by quasi-distributed fiber Bragg gratings and implanted six optical fibers with 13 (FBGs) each into interface 110 kV insulator. Natural cover tests were done at an observation station in Guizhou, China, study types mechanisms cover. A...
Icing on transmission lines may cause damage to tower components and even lead structural failure. Aiming at the lack of research predicting mechanical characteristic parameters weak towers, cumbersome steps building a finite element model (FEM), study prediction for towers based simulation machine learning is proposed. Firstly, 110 kV in heavily iced area taken as an example establish its FEM. The locations are analyzed, accuracy FEM verified. Secondly, meteorological terrain considered...
Overhead distribution lines are widely distributed and the environment is complex. At present, most of overhead in urban–rural fringe rural areas bare lines. These susceptible to contact with tree barriers, airborne objects, construction machinery, resulting safety problems, such as tripping accidents casualties caused by electric shock. In order solve hidden problems lines, an insulation skin-wrapping robot for designed proposed innovatively this paper. The mechanical system control...
In this study, the meteorological fields for 2001, 2010, and 2022 were simulated using WRF (Weather Research Forecasting) model, based on land use data from Chengdu its neighboring satellite cities. The purpose is to uncover effects of urbanization extreme high-temperature weather urban heat island phenomenon. It was found that notably elevates temperatures in Chengdu's central new areas, with a significant increase 2022, whereas areas like Longquan Mountain, unaffected by urbanization,...
