Flattening the radial-force sum eliminates the multiples of the third radial-force component. These components excite the breathing mode vibration, which is typically the dominant vibration in switched reluctance motors with a high number of poles. The previously proposed analytical current derivation for flattening the radial-force sum neglects magnetic saturation, limiting its applicability to low-torque region. Consequently, for high-torque saturation conditions, the previous waveform shaping degrades in flattening the radial-force sum. The proposed refinement of the analytical current waveform addresses this limitation, enabling effective radial-force sum flattening even under high-torque conditions. Additionally, the proposed current exhibits significantly lower peaks than those of the flattening methods at high-torque region in the literature, mitigating the need for higher-rated inverters. Finite element analysis and experimental validation verify the effectiveness of the proposed method.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"325-337"},"PeriodicalIF":7.9,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10613515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed control method named multiparallel vector current control is a variant of virtual synchronous machine (VSM) applied to the multiparallel inverter system (MPIS). It takes on the good qualities of VSM control, such as offering inertia, voltage support, the ability to operate in standalone mode, and strong performance in weaker grids. Moreover, this concept boasts swift current set-point tracking abilities and enhanced synchronization properties. Integration of the P2G system involves an MPIS that transforms ac power from renewable sources into usable dc power, along with an electrolysis device. The later utilizes dc power source to generate hydrogen and oxygen by decomposing water. This integration strategically prevents grid-induced overvoltage or undervoltage from affecting the electrolysis device. This protects it from malfunctions or damage while keeping the voltage and frequency within the normal range. The efficacy of the proposed control method is rigorously substantiated through analytical models, time-domain simulations, and experimental validation in real-world applications. This comprehensive validation process underscores its viability and robustness in ensuring grid stability while facilitating efficient P2G conversion operations.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"311-324"},"PeriodicalIF":7.9,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10601332","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141746211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In practice, TSA based on deep learning is preferable for its high accuracy but often overlooks challenges in maintaining data privacy while coping with network topology changes. This article proposes an innovative \u0000<underline>f\u0000ocal \u0000<underline>l\u0000oss-based multihead \u0000<underline>a\u0000ttention \u0000<underline>co\u0000nvolutional \u0000<underline>n\u0000etwork (FLACON) for accurate post-disturbance TSA under both symmetrical and asymmetrical smart grid faults. The proposed approach effectively incorporates cross-domain deep federated transfer learning (FTL) to leverage local operating data for TSA in a decentralized fashion. By introducing convolutional layers alongside multi-head attention mechanisms, the FLACON framework significantly improves learning efficiency across geographically distributed datasets. To address the challenge of class imbalance, the model integrates a balance factor-enhanced focal loss function. The FTL architecture enables decentralized model training across various clients, thus preserving data privacy and reducing the burden of communication overhead. To avoid the constant adjustment of hyperparameters, the FLACON employs an inductive transfer learning approach for hyperparameter tuning of the pre-trained model, markedly decreasing training time. Extensive experiments on datasets from the IEEE 39-bus system and the IEEE 68-bus system demonstrate FLACON's exceptional accuracy of 98.98% compared to some competitive alternatives.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"253-266"},"PeriodicalIF":7.9,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10592792","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141585845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed model provides critical information on the transient grid status in the early stages of fault occurrence, which may lead to taking the proper action.

The conventional approach to these tests is to increase the stress by either increasing the pulse length, or decreasing the inductor's size. However, for evaluation of the novel trench SiC \u0000<sc>mosfet\u0000s, increase of electric field by voltage can be more influential to detect the degradation patterns and exact point of failure. This article, for the first time, investigates the avalanche rating to failure of the similarly rated SiC power \u0000<sc>mosfet\u0000s in planar, symmetric double-trench and asymmetrical trench structures through incremental increase of applied voltage as the “high energy” technique to investigate the mechanisms of dynamic avalanche under elevated electric fields. Using this approach, the electrothermal stress is induced by incremental increases of voltage source on UIS at a range of temperatures between 25 °C and 175 °C. Silvaco technology computer-aided design (TCAD) simulations have been developed, validated, and analyzed to evaluate the stress mechanisms to failure. The measurements, validated by TCAD, show that some failure mechanisms when stress is elevated by increase of source voltage are different than the case of “high current” avalanche initiation by increase of pulse durations as reported in the past. In planar device, the peak electric field plays a key role in failure, as is the failure in symmetric device at low case temperatures. In asymmetric device, the critical avalanche energy of failure in both cases of 25 °C and 175 °C are very close, suggesting independence from the thermal headroom.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"235-252"},"PeriodicalIF":0.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10547411","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141319617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nonintrusive nature of these sensors gives operational and economic benefits in installing them at the existing distributed generation sites and power substations. These sensors are linear in operation, free of saturation, and need minimum duration or no outage for installation as compared to the conventional current transformers. This article describes magnetic field simulation, calibration, and experimental validation of magnetic sensors for accurate measurement of three-phase currents. Laboratory experiment results of three-phase low current measurements for two types of overhead structures: triangular and horizontal are rendered as a validation of the proposition. The performance verification of these sensors is further achieved by conducting field experiments for measuring currents up to 1500 A. The sensors yield promising results with a maximum error of 1.15% in the estimation of three-phase currents. The magnetic sensors showed satisfactory performance in accurately reproducing current waveforms consisting of fundamental frequency and harmonics that are typically present in modern power grids.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"143-154"},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10480244","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140311996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variational autoencoder (VAE) techniques have emerged as a promising tool for fault classification due to their robustness in handling complex data. However, the inherent nondeterministic aspect of the VAE creates a significant challenge as it leads to varying cluster locations for identical health states across different machines. This variability complicates the creation of a standardized applicable diagnostic tool and challenges for the implementation of effective real-time health monitoring and prognostics. Addressing this issue, a novel approach is proposed wherein a desirability function-based term is integrated into the cost function of the VAE. The enhancement achieved by this approach arises from the standardization of classification, guaranteeing that analogous faults are assigned to identical geolocations within a 2-D user-friendly space. This method's efficacy is validated through two separate case studies: one analyzing vibration data from two diverse designs of large existing hydrogenerators, and the other utilizing vibration data sourced from an open-access dataset focused on bearing fault. The findings of both studies show that the model can cluster 97% of similar faults into preset zones, compared with 40% when the desirability term is excluded.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"106-116"},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10478716","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140312142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
