However, these newly developed PM motors are still in their early design stages and face various challenges. In order to overcome these drawbacks, further development of these motor topologies is necessary. One such new motor topology is the ring winding axial flux permanent magnet (RWAFPM) motor. Enhancing the performance of this motor requires optimising its geometry, which can be a time-consuming process when using the three-dimensional (3D) finite element method (FEM). It is essential to propose a two-dimensional model that offers faster processing but lower accuracy to address this issue compared to 3D FEM for this motor. Due to the three-dimensional structure of ring-winding axial flux machine|axial flux motors, creating a two-dimensional (2D) model for this motor presents a significant challenge. In this article, while studying the RWAFPM motor, the simplifications to the motor's geometry have been proposed in order to create a 2D model that provides sufficient accuracy as a substitute for 3D FEM. To validate our findings, the Schwarz–Christoffel conformal mapping technique has been employed to extract the modelling results. Finally, these findings have been compared with the outcomes obtained from the 3D simulation. Validation. Validation of 3D finite element results has been done by experimental results.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"19 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143397084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure high reliability in high-power wind and photovoltaic power generation systems, conducting fault diagnosis for T-type three-level rectifiers is crucial. This paper first analyzes the input current characteristics of both in-phase and out-of-phase dual transistor open-circuit faults. A current-extended observer is developed using a hybrid logic dynamic model to estimate the current value during normal operation. The residual state equation is derived by comparing this estimated current with the actual fault current. A residual information table for fault currents is created through differential solutions of the residual state equation, enabling fault localisation by comparing the residual information against predefined threshold values. Finally, the feasibility and accuracy of the proposed fault diagnosis method are validated through simulations and experiments.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"19 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.12536","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, low-frequency noise, such as fan noise, often obscures critical features. This study introduces an adaptive low-frequency denoising algorithm based on the filtered-x least mean square (FxLMS) model. By optimising the step size and convergence factor, the algorithm resolves the peak offset issue in traditional LMS methods, enhances denoising performance and computational efficiency, and demonstrates effectiveness in practical scenarios. Using denoised acoustic data, quantitative analysis based on information entropy (frequency complexity analysis (FCA)) evaluates changes in mechanical properties. The analysis indicates that healthy transformers exhibit lower FCA values, whereas aged transformers show values approximately double those of healthy units, reflecting the mechanical changes associated with normal ageing. Further analysis of transformers commissioned in 2004 reveals that FCA values of abnormally aged transformers exceed three times those of typically aged units, indicating severe mechanical degradation. These findings demonstrate that combining the FxLMS algorithm with FCA analysis effectively extracts denoised acoustic features and distinguishes between healthy states, normal ageing, and abnormal ageing in transformers.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"19 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.12545","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The whale optimisation algorithm (WOA) is introduced to obtain the optimal hyperparameter, and the WOA-DRBF surrogate model optimisation strategy is used to improve the fitting and optimisation ability. After optimisation, the HST corresponding to the size of the block washers decreased by 3.67°C, and the maximal temperature rise decreased by 12.93%, effectively ameliorating the phenomenon of excessive local temperature rise within each partition. Comparing the above optimisation results with those of the WOA-RBF static surrogate model and the genetic algorithm (GA), the proposed method shows superior performance in both optimisation search capability and efficiency. Comparing the optimisation efficiencies of the three methods, the number of model calls for the WOA-DRBF method is 23.89% of the WOA-RBF method and 1.77% of the GA method, respectively.

However, the existing open-loop current control method for HIMC may bring in low-order harmonics if the injected harmonic current deviates from its desired value. To address this issue, this paper proposes a closed-loop input current control strategy based on the waveform similarity index (WSI) for these emerging MC topologies. The WSIs are defined as the ratios of the corresponding input currents against the maximum and minimum input voltages. Multi resonant controllers are adopted to regulate the WSI difference so that its low-order harmonics are eliminated, which generate an additional signal to correct the injected harmonic current. By adopting the proposed current control strategy, the 5th and 7th harmonics are suppressed to lower than 1.0% under the sinusoidal input voltages and nominal load scenario. Even with inaccuracies in the reference harmonic current generation, the proposed strategy enables the input currents to approach sinusoidal waveforms with significantly reduced WSIs difference, thus enhancing the input power factor over the conventional open-loop method. Besides, the proposed method is effective under unbalanced and distorted conditions through the experimental verification.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"19 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Secondly, the open-set discriminant model based on the extreme value theory is proposed, and the data output by transformer is input into classifier to realise open-set fault diagnosis.

Therefore, the sequential Taguchi optimisation method is proposed to improve the performance of ARFHE-PMSM and reduce computation burden. The torque, torque ripple, core loss and permanent magnet volume of ARFHE-PMSM are optimisation targets. In the optimisation process, the design parameters are divided into non-sensitive and sensitive parameters based on the sensitivity analysis results. The non-sensitive parameters are first optimised through the finite element model and then the sensitive parameters are optimised. The motor's manufacturing errors are considered in the optimisation process, and the Gaussian membership function and characteristic index are utilised to transform the multi-objective optimisation problem into a single-objective optimisation problem. The iterative Taguchi method narrows the optimisation scope until the convergence conditions are met. The optimal combination of different design parameters of the motor is obtained by analysing the experimental results.
