In Nordic countries, heat pumps have been gaining popularity during the past years and have become one of the leading ways of heating in households and smaller public buildings. Although not a very complicated setup, the devices used are still prone to unexpected failures, especially if wrongly chosen, installed or maintained. The paper presents a study conducted on five real-life cases with very similar outcomes and failure modes. The setup of the systems is explained, faults are listed and presented, causes of the faults including modeling and measurement data are provided. The suggestions are given to overcome such faults in similar setups in the future.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128840035","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}

One of them is mechanical faults that occur within the windings and magnetic core of the power transformer. In order to carry out diagnostics for this type of fault and evaluate whether there is a mechanical defect present, it is necessary to obtain information about the generated vibrations inside of the structure of transformer from the measured values on the transformer tank. However, these vibration values are distorted since they propagate the transformer structure before being received. Therefore, a simulation of vibrations generated by the transformer is made using a mass and spring system and a dynamic genetic algorithm in order to acquire the corresponding spring stiffness coefficients that generate the measured vibration values on the tank surface. This paper describes a case study created in MATLAB software for a single magnetic core rod of a large power transformer.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122720878","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}

However, the SRM exhibits large torque and large input current ripples, deteriorating driving comfort and battery lifespan. Furthermore, a driving system of the SRM requires the special inverter topology with additional switching or rectifying devices, leading to the cost-up. Meanwhile, the SynRM does not have these drawbacks, although this motor tends to be difficult to cover the wide range of the torque and the rotation speed required for vehicle propulsion because of large phase flux induction. To solve the obstacles of these conventional reluctance motors, this paper proposes a novel reluctance motor. The proposed reluctance motor is based on magnetization by the sinusoidal phase flux waveform, whereby the torque and input current ripples are eliminated using a common three-leg inverter without inducing large phase magnetic flux. This paper presents the operating principles of the proposed reluctance motor as well as analysis and simulation results in comparison with the SRM and the SynRM. As a result, the proposed reluctance motor is elucidated to reduce the torque and input current ripples with the three-leg inverter. Furthermore, the proposed reluctance motor can improve the torque range and rotating speed range compared to the SynRM because of the sinusoidal flux waveform with reduced amplitude. These results imply feasibility of the proposed motor for vehicle propulsion.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"363 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115976731","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 machine’s future behavior is predicted for a finite set of voltage vectors that the power converter can generate, and then an optimal voltage vector is selected based on a cost function. The cost function is designed considering torque reference tracking and field weakening operation for speeds above rated, while the system constraints are handled as soft constraints and included in the cost function. The proposed control scheme is verified by simulation tests in MATLAB Simulink, and the impact of inductance error on torque reference tracking is investigated. The simulation results have shown the effectiveness of the proposed control scheme. The magnetic saturation effect of the machine is considered and incorporated into the simulations using flux maps.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"82 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128160943","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}
