This paper firstly constructs the distributed-parameter model for high-voltage cables. Then, the model is simplified to improve computational efficiency. Finally, a fault distance estimation algorithm is proposed based on the simplified model. There are three main contributions. First, the differential equations are decoupled by similarity diagonalization and inverse transformation to obtain voltage and current expressions of core, shielding and armor layers with respect to distance. Second, considering measurement ranges, the complex nonlinear formulas are transformed into the linear polynomial ones by using Taylor expansion. A fault distance estimation algorithm using voltage continuity principle is proposed for coal-mine cables. Third, the experiment model of high-voltage coal-mine cables is created by PSCAD/EMTDC. The experiment results show that the established model reduces voltage and current estimation errors to below 1.2 V and 0.15A, respectively. The method completes all calculations in only 0.01 s. The maximum error does not exceed 100 m and minimum one is only 1m under various conditions.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 4","pages":"1811-1824"},"PeriodicalIF":3.8,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488500","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}

The basic problems of the cable transmission line theory are reviewed first, while developing the fault location method by using the dual-ended travelling wave technique. Then, it proposes wave velocity correction and calibration methods that consider the central frequency and its deviation during signal transmission. A simulation is designed to validate the method, considering the effects of noise and damage level on location accuracy. The simulation results indicate that the calculated fault location is 1527.40 m, with a relative error of 0.548%. Moreover, the impact of noise and the extent of damage on the localization outcome is minimal. Fault location experiments were carried out on a 105 m cable, resulting in a fault error of 2.16%, which also confirms the accuracy and effectiveness of the method.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 4","pages":"1825-1835"},"PeriodicalIF":3.8,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479322","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}

Existing practices usually monitor condition of the overall health of the power cable circuits but overlook its intricate structural complexity. This letter proposes a data-driven health assessment method considering both failure-related structural characteristics of each cable circuit and condition measurement data. Firstly, distinguishing failure indicators are identified by integrating in-depth component analysis with circuit condition measurements. Based on these features, a novel integrated health index is proposed, named as One-sample Maximum Mean Discrepancy (O-MMD), which evaluates the health condition of a circuit by quantifying the disparity between un-faulted assets and typical faulted groups in a high-dimensional feature space. This approach is able to assess whether new or modified circuits might exhibit similar fault characteristics as previously observed cases. Based on the O-MMD index, the probability of failure can be estimated for each cable circuit, and the maintenance plan can be prioritized. The proposed method is demonstrated on both seen and unseen real-world underground cable system data in Singapore.","PeriodicalId":13498,"journal":{"name":"IEEE Transactions on Power Delivery","volume":"40 4","pages":"2443-2446"},"PeriodicalIF":3.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144335372","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}
