In this case, the power factor is significantly reduced, and the correct measurement of power and energy is challenging. International standards do not specify accuracy requirements for power and energy meters under non-sinusoidal conditions, and their accuracy is therefore questionable. On the other hand, penalization of low power factor operation and power factor correction are based on power and energy measurement. The guidelines for power measurement under non-sinusoidal conditions can be found in IEEE 1459 and are rarely used in practice. In this paper, a case study is carried out with measured data from an industrial plant where high harmonic distortions of current and voltage are present and active harmonic filters are installed. From the measured voltages and currents under sinusoidal and non-sinusoidal conditions, the electric power quantities are calculated according to IEEE 1459, the Budeanu theory, DIN40110, and two methods used by typical power meters: the quarter-cycle voltage delay method and the integral voltage phase shift method. The results have shown that typical power meters are subject to significant errors under industrial conditions. In addition, the electric power quantities determined by different power theories and standards can vary significantly under non-sinusoidal conditions.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"29 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":"125060265","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}

Negative-Sequence-Voltage-Based cluster voltage balancing control has a large capability in regulating active power. To improve the dynamic response of cluster voltages under unbalanced grid conditions, cluster voltage balancing feedforward control is usually introduced. The negative sequence voltage in the conventional feedforward control is derived in $alpha beta$ frame, which introduces anti-trigonometric functions and makes the calculation very complex. In addition, the relation between positive sequence current control and negative sequence voltage is neglected, which makes the negative sequence from the feedforward control inaccurate. In this paper, a novel feedforward control algorithm is proposed. The novel algorithm uses the dc form representation in dq frame and takes the relationship between positive sequence current and negative sequence voltage into consideration. Hence, the proposed feedforward control is more straightforward and accurate. The proposed control scheme is verified by the experimental results from a 400 V/ ±5 kVar CHB STATCOM.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"25 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":"127143204","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 transformers’ dependability and consistency are the most important criteria for the power system networks since the transformer failure may result in high capital loss. Failures occur due to various reasons, which include areas of failure in windings, bushings, tap-changers, core, tank, protection system, cooling system, etc. Finite element modeling can help design power transformer and understand the severe condition of defects while considering real-life conditions. Finite element method (FEM) is used to simulate and investigate power transformer insulations with partial discharge activities. FEMs provide more accurate representation of complex geometries because they consider thermal, electrical, and environmental influences on the insulation models to obtain basic characteristics of the insulation system during normal and partial discharge conditions. The defects have been taken into account are bubbles, cellulose, and metallic defects in the oil and voids and cracks in pressboard insulation. The aim of this paper is to design and analyzing the transformer’s defect in the time domain. The electric field is estimated in healthy as well as for the defective transformer.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"1 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":"121519543","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}

Using a dedicated software, National Instruments VeriStand, the authors prove the possibility of performing vehicle testing for a period of actual mobility time recorded inside the urban scenario. Such long-time simulations are extremely time consuming or impossible to perform using computer-based simulators. One solution is to decrease the model complexity in order to perform these simulations, however the computation time still reaches periods beyond the actual analyzed one. Using VeriStand, the model complexity is kept at its maximum, hence the accuracy and the performances are not diminished. The required computation time is the actual mobility time. Hence, the same time can be applied for an actual test-bench, proving via comparative analysis the quality of the results and the accuracy of the model under test. The considered application is an electric scooter, equipped with a 300W permanent magnet synchronous machine (PMSM), supplied via an inverter from a source of 36 VDC. The model of the PMSM is a flux-linkage one designed in Matlab Simulink and exported into VeriStand running on a NI-PXIe 8135 Embedded Controller. The entire study is validated with experimental measurements performed with the actual machine under study.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"35 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":"127991281","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 BSIM3 model, which is developed for CMOS logic devices, is adopted with its proven robustness and fidelity to describe the channel behavior of the power MOSFET. On the other hand, the extended components including the drift region, body-diode and drain-gate capacitance are defined according to the vertical MOSFET structure which is different from conventional CMOS devices. The temperature-dependent parameters in the original BSIM3 expression are used to contribute to an improved dynamic thermal model. The improved model can estimate the power loss-caused temperature increase and dynamically feed it back to the BSIM3 temperature-related parameters and instantaneously control the behavior of the electrical model. The parameters of the model are extracted based on the measurement of the static characteristics and the intrinsic capacitances of a Si vertical power MOSFET. The result shows that the proposed model is able to describe the device characteristics precisely.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"24 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132810565","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}
