Existing mitigation methods typically require the application of additional external equipment on conductors. In this study, the inhibitory effect of load current cycling transferred ice-melting technology (LCCT) on bundled conductors is investigated to eliminate the need for supplementary devices. The underlying principles are analyzed, a numerical simulation model is developed, and field experiments are conducted under natural environmental conditions. The results demonstrate that the inhibitory effect varies significantly with changes in the ice thickness and ice-melting conditions. For ice thicknesses ranging from 5 mm to 25 mm under identical melting conditions, the inhibitory effect increases by 67.8%. The most effective inhibition (93.4% average) occurs at the 25-mm ice thickness. Among the ice-melting conditions, H4 has the greatest inhibitory effect (95.4%). Other conditions yield inhibitory effects ranging from 2.6% to 76.2%. Field experiments confirm that condition H4 achieves a 91.4% inhibitory effect on four-split transmission lines.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 3","pages":"1769-1776"},"PeriodicalIF":3.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, dampers may develop internal structural anomalies (e.g., damage to damper heads) or external positional anomalies (e.g., slippage along the conductor), both of which compromise vibration suppression efficacy. Existing anomaly detection methods focus on single anomaly type and struggle with local feature extraction. To address these limitations, this paper introduces SKAD, a unified framework guided by structural knowledge, to concurrently detect internal and external damper anomalies. SKAD encodes structural properties of dampers through four key structural points, enabling sub-pixel-level localization via a hybrid network (HRNet + GAU + SimCC). By analyzing spatial relationships and vector features of these structural points, SKAD can simultaneously detect anomalies like damage (via confidence thresholds and vector dot products) and slippage (via depth-parallelism-distance constraints) at the structural level. Experiments on a real-world dataset demonstrate SKAD outperforms object-based methods in accuracy and robustness, providing novel transmission line inspection perspectives, ensuring early anomaly detection to prevent conductor fatigue and power outages.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 3","pages":"1743-1753"},"PeriodicalIF":3.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its distributed muti-terminal grid structure raises the complexity of the whole system drastically. To clarify the oscillation mechanism of the multi-terminal cascaded hybrid HVDC system, utilizing the merits of the impedance model, this paper proposes an impedance based stability analysis method, which decomposes stability analysis problem into a hierarchical structure. In addition, an equivalent single-input single-output (SISO) impedance based method is proposed together for oscillation propagation analysis, which could depict how the oscillation spread from the perspective of the physical impedance network. Oscillation suppressing methods including impedance reshaping and parameter retuning could be tailored with the instruction of the impedance based stability analysis and thereby efficiency is improved considerably. The analytical results and the control method are verified through the electromagnetic transient simulation with practical data.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 3","pages":"1754-1768"},"PeriodicalIF":3.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143836847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
