To estimate the slip speed at the peak adhesive force value, the vehicle and wheel speeds are required. In this study, maximum adhesive force control was proposed, which involves estimating the vehicle speed using the LPF of the driving-wheel speed instead of the vehicle speed. Simulation results indicate that the torque was successfully controlled to drive at the maximum adhesive force. In addition, the proposed control method was validated using a wheel-rail test bench.","PeriodicalId":45552,"journal":{"name":"IEEJ Journal of Industry Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135110520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High responsiveness and a simple construction have been achieved using the method.

Supplying electricity is difficult in some remote islands in Indonesia, such as Adaut regency of west Maluku. One solution to solve this electricity supply problem is the creation of a microgrid system. However, the application of renewable energy on microgrids can lead to several technical challenges, such as frequency disturbances and voltage instability. Therefore, a control algorithm that can maintain the system stability is required. One recently developed algorithm is the synchronverter. In this study, the synchronverter is used to maintain network stability on an islanded wind farm based microgrid. As a result, we asses the microgrid stability responses with the synchronverter algorithm or a conventional synchronous generator to evaluate the microgrid stability performance. The outcomes of this study indicate that the synchronverter algorithm can maintain the stability of microgrid even it is interrupted by intermittent wind speed input and load changes.","PeriodicalId":45552,"journal":{"name":"IEEJ Journal of Industry Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135011310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine the IGBT junction temperature, the transient thermal resistance of an IGBT device on the order of micro seconds is estimated by transient thermal simulations. The saturation current without self-heating effects is estimated based on a short-circuit test and the transient thermal resistance. The IGBT SPICE parameter is extracted from the saturation current characteristics during the short-circuit state. The coupled electrical-thermal simulations with the SPICE model and thermal resistance model are applied to several short-circuit evaluations with different parasitic impedance and gate driving condition, and the results are consistent with the measured current and voltage waveforms.","PeriodicalId":45552,"journal":{"name":"IEEJ Journal of Industry Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135011316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reusing the machine windings of an electrical machine as inductors, e. g. in DC-DC converters for onboard chargers, saves weight and space. However, currents in the machine windings when operating as DC-DC converter can result in undesired torque ripple generated by the machine. Therefore, stable rotor positions of a switched reluctance machine have to be found to prevent it from rotating in DC-DC converter operation mode. In this study, stable rotor positions for a wide range of current distributions are determined, enabling flexibility in the choice of currents. A method to analyze such stable equilibrium positions for switched reluctance motors is presented. The proposed method is used to determine the stable positions that facilitate flexible current distribution between phases. Moreover, locus curves are calculated, simulated, and measured to illustrate and evaluate stable rotor positions for the various current distributions.","PeriodicalId":45552,"journal":{"name":"IEEJ Journal of Industry Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136011566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The static eccentricity of the rotor is a common fault in the fabrication process. These faults cause imbalanced electromagnetic force and exert unexpected vibration and acoustic noise during the design process. In the worst case, it causes bearing or motor failure. This research investigates the impact of this fault on the temporal and spatial harmonic distribution of gap flux density and electromagnetic force. Moreover, a compensation method has been proposed to suppress imbalanced force due to static eccentricity by using a triple three-phase winding motor. By controlling the three inverters independently, the winding current of each group can be controlled. Therefore, the gap flux density and electromagnetic force in each group can be brought into a desired state. Therefore, the imbalanced electromagnetic force can be restored using this system. In this paper, the effectiveness of the proposed method is verified by Finite Element Analysis (FEA) and experiment.","PeriodicalId":45552,"journal":{"name":"IEEJ Journal of Industry Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135011309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To accelerate research and evaluation, we propose an efficient Internet-of-things (IoT) platform called the SUSTIE Core Engine. The platform gathers data in real time, stores both design data and time-series data with coordinates, and act as simulation interface to satisfy three requirements of an IoT platform for smart facilities: an architecture that allows adding / removing functions without stopping operation, data management features for time-series / coordinates data, and common interface for simulations / controls. We implement the platform which covers the requirements to on-site system in the test facility, and evaluate the gateway, spatiotemporal database, and simulation interface.
