These issues include a one-sample time delay and low-pass filter in the current measurement channel. The proposed method involves estimating the time delay using a predictive extended state observer (ESO) within the current loop of the PMSM to enhance anti-disturbance capabilities and robustness. Initially, a discrete-time model that takes current loop time delay into consideration is established. Subsequently, a predictive ESO is designed to estimate disturbances within the current loop. This ESO incorporates known model information to improve the accuracy and speed of disturbance estimation. Furthermore, compensation is made for the time delay stemming from the low-pass filter in the current measurement channel to enable real-time current detection. Lastly, the disturbance estimated by predictive ESO is combined with the feedback control law to form a model-enhanced active disturbance rejection current controller.

A diverse dataset generated through Latin hypercube sampling (LHS) is used to train the ANN, which employs customised activation functions to accurately capture the non-linear characteristics of the magnetic gear. Bayesian optimisation is applied to fine-tune the hyperparameters, resulting in a significant reduction in computational time. The proposed approach leverages deep learning to efficiently accelerate the multi-objective optimisation process, providing accurate predictions of SP-RMG performance metrics. The optimisation results demonstrate significant improvements with the model predicting optimal design parameters that enhance torque performance, reduce torque ripple by 47.2%, and decrease total weight.

Thanks to effective PM placement, the torque density is improved by 65% and 29% compared to the CFRPM and CPFRPM, respectively. PM demagnetisation, along with a thermal analysis, is developed to guarantee that the PMs are not prone to demagnetisation.

It has become an urgent task to introduce digital technology to monitor and analyse the hot spot temperature in real time. In this paper, the magnetic, current and thermal multi-field coupling numerical analysis method is used to establish the digital model of the transformer and carry out simulation analysis, and the transformer loss data and temperature distribution are obtained. Infrared thermal image thermometer, thermocouple temperature measuring device and optical fibre temperature sensor are used to monitor the thermal state characteristic parameters of the transformer. From the two dimensions of multi-source and heterogeneous, a multi-source heterogeneous information fusion method is proposed to extract, clean, and filter experimental data. Taking 100 sets of data as the sample data, the first 80 sets of data are used as training sets to construct a BP neural network model optimised by the genetic algorithm, and the last 20 sets of data are used as prediction sets to test the model, so as to predict the hot spot temperature. By comparing with other algorithms, it is found that the evaluation constraint index of GA-BP is the smallest, MRE is 0.0651 and RMSE is 0.2158. MSPE was 0.44%.

Traditional permanent magnet synchronous machines utilise rare earth minerals for rotor flux generation, posing challenges due to rising costs. In such conditions, wound rotor synchronous machines with electromagnets may offer several economic and operational benefits, particularly for applications requiring a wide range of speeds and better torque density. However, rotor excitation in these machines requires brushes and slip rings, which lead to higher initial and maintenance costs, increased sensitivity to fluctuations, reduced speed regulation, and lower power factor. Existing designs of brushless wound rotor synchronous machines use additional rotor windings, leading to increased complexity and reduced efficiency. Techniques such as third harmonic excitation have been employed to eliminate brushes, but these solutions often suffer from low starting torque and inefficient stator utilisation. To overcome the issues associated with existing brushless wound rotor machines, this article proposes a novel winding scheme that incorporates an additional stator winding to enhance the slot fill factor. Furthermore, the benefits of single and dual inverter-fed designs are analysed, highlighting the reduced cost, size, and simplified circuitry of the single inverter design, along with the improved control and performance offered by the dual inverter design. Finally, an advanced harmonic excitation method is integrated to optimise torque production. A thorough 2D finite element analysis has been conducted to validate the proposed designs and operational principles of the brushless wound rotor synchronous machine, demonstrating its potential for enhanced performance in various electric machine applications.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"19 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689330","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, traditional systems face application limitations due to low-frequency transformers and inefficient power converters. This article proposes a four-port solid-state transformer (FPSST) to enhance large-scale energy generation from renewable sources. The FPSST incorporates a modular multilevel converter to collect both medium-voltage ac and dc from wind and solar systems. Following this collection, high-frequency transformer-based dc/dc converters ensure galvanic isolation between ports by enabling a compact, lightweight and efficient design due to the advanced magnetic material. A cascaded H-bridges multilevel inverter produces HVAC with reduced harmonic distortion and precise voltage regulation. Moreover, a series-connected two-quadrant converter generates HVDC, providing a stable dc output through a discretised dc-link capacitor. The performance of the proposed FPSST is thoroughly investigated using the MATLAB/Simulink platform, which offers insight into system behaviour. Prior to experimental validation, an amorphous alloy-based high-frequency transformer is developed in the laboratory, and a 1-kW sealed-down FPSST is constructed. Simulation and experiment results confirm the feasibility and effectiveness of the proposed FPSST. Thanks to its compact, modular design, the four-port SST can be easily scaled, enabling both HVAC and HVDC generation from renewable sources.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"19 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689574","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}

Therefore, this paper proposes a new approach to transformer winding modelling. Firstly, based on the design parameters of the transformer, a finite element model constructed using ANSYS Maxwell simulation software is used to calculate the capacitance, inductance, and resistance parameters of the transformer winding. Secondly, the model not only considers the capacitance effect between distant conductors and the mutual inductance between distant coils but also considers the frequency variation effect of parameters. Subsequently, an equivalent circuit model is formulated with the acquired parameters to analyse the frequency response characteristics of the winding. Finally, the equivalent winding model was subjected to various mechanical fault simulations across different operating conditions to investigate the alterations in the frequency spectrum curve under fault conditions. The results show that the simulated IFRA curve closely aligns with the measured IFRA curve, providing indirect evidence of the effective correspondence between the circuit model, which considers various influencing factors, and the actual physical model.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"19 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595064","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}

Besides, they can effectively utilise both the magnetic and reluctance torques, thus, they can play an important role in many industrial applications including electric transportation systems. Up to now, more or less, the conventional distributed-windings are employed in design of the synchronous reluctance machines. However, recent advancements have seen the adoption of fractional-slot concentrated windings (FSCWs) due to their shorter end-winding length, simpler structure, and higher slot fill factor. Although FSCWs offer these advantages, they also suffer from higher magnetomotive force (MMF) space harmonics, which can lead to undesirable effects such as localised iron saturation and increased core losses. The main target of the present research was introducing the winding layouts, which have the benefits of both FSCWs and distributed windings to use in PM-assisted synchronous reluctance machine. To solve the problems related to FSCWs, in this research, the stator slot-shifting has been developed and new types of fractional-slot winding topologies, comprising significantly low MMF harmonics and short-end windings length have been proposed. Based on these proposed winding configurations, a prototype machine was built as case study; and analytical results, finite element analysis, and experimental tests were conducted to validate the machine’s characteristics. Although in the proposed machine the winding is converted to overlapped type and is not concentrated anymore, but the obtained results show significant advantages over the conventional design in terms of air-gap flux density, back electromotive force, torque profile, power factor, power losses, efficiency and flux weakening capability.","PeriodicalId":13352,"journal":{"name":"Iet Electric Power Applications","volume":"19 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/elp2.70002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571366","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}
