“…From (14), it can be realized that each current component depends only on the error relating to its own axis (ε dr and ε qr ) and not on both of them, and this is achieved only if a perfect decoupling is ensured through the proper choice of the gain K.…”

“…The corresponding studies used different forms of generation units; some of them have utilized the squirrel-cage-type induction generators (SC IGs) with a capacitor bank connected across the stator terminals to provide the reactive power as reported in [6][7][8], while the others have utilized the synchronous generators that have stator terminals connected to the grid through a converter as stated in [9][10][11][12]. The problems related with these generation units were the disability to operate at variable wind speed, and the difficulty to recover the excessive power to the grid [13,14]. The superiority of the doubly fed induction generator (DFIG) over the other types of wind generators, such as the SC IG, can be clarified through analyzing the mechanism by which the generation unit can handle the power for the variable speed operation.…”

Effective Direct Power Control for a Sensor-Less Doubly Fed Induction Generator with a Losses Minimization Criterion

et al. 2020

The present paper is concerned with introducing an effective direct power control (DPC) approach for a sensor-less doubly fed induction generator (DFIG). The derivation of the proposed DPC approach is performed in a systematic manner in which the design of the rotor current controllers is well analyzed, which clarifies the real base of the control system as when and why it works properly. The operation of the proposed DPC approach is based on the stator voltage-oriented control principle in which the stator voltage is aligned with the quadrature axis of the rotating reference frame. To obtain maximum generation efficiency, the reactive power reference value is derived based on a loss minimization criterion (LMC) that is described and analyzed in detail. To enhance the robustness of the control system, an effective rotor position estimator is proposed that is robust against the system uncertainties, such as the parameters’ variation. To validate the effectiveness of the proposed sensor-less DPC approach, the DFIG dynamic performance is tested for a wide range of operating speeds. The obtained results confirm and emphasize the feasibility of the proposed control approach and its LMC methodology in improving the generation efficiency and in obtaining high dynamic performance from the DFIG.

Meskipun simulasi dan laboratorium virtual menawarkan suplemen berharga untuk ceramah formal, namun teknik ini tidak menekankan implementasi perangkat keras dan aspek fisik system [12], Mengingat bahwa persentase daya listrik yang diolah melalui konverter daya terus bertambah, kurikulum tradisional yang berfokus pada mesin listrik handal untuk sistem daya ac besar tidak lagi sesuai [13] .…”

A meta-analysis was conducted to synthesize existing studies comparing the effects of Problem Based Learning and virtual laboratory versus traditional instructional media on student learning outcomes. Sixty-three studies were placed in this meta-analysis, and the results showed that Problem Based Learning and virtual laboratory learning media were more effective than instructional methods. The results of this study indicate that Problem Based Learning and virtual laboratory learning media clearly have a more positive effect on student learning than instructional methods. Keywords : Virtual Laboratory, Students Achievement, Problem Based Learning

“…There is a trend in engineering education toward remote courses and "virtual" laboratories [9]- [13]. While distance education programs can often reach a wider audience than on-campus programs, it is exceedingly difficult to provide truly hands-on experience in power electronics and renewable energy over the internet.…”

Power electronics and renewable energy are two important topics for today's power engineering students. In many cases, the two topics are inextricably intertwined. As the renewable energy sector grows, the need for engineers qualified to design such systems grows as well. In order to train such engineers, new courses are needed that highlight the unique engineering challenges presented by renewable energy systems. This paper presents the theory, implementation, and assessment of a new laboratory course designed to teach power electronics and renewable energy to engineering students. A key element of the course is the use of real renewable energy systems in the laboratory setting. Students design, test, and troubleshoot power electronic circuits (such as dc/dc converters and pulse-width-modulated inverters) with tools used widely in industry (such as MATLAB/Simulink and dSPACE digital signal processors). Ten unique experiments are presented, as well as detailed descriptions of two open-ended design projects: a maximum power point tracker for a photovoltaic array and a full converter for a permanent-magnet wind turbine. Results from students' work on the experiments and final projects, as well as an assessment of the effectiveness of the course based on pre-and post-testing, are also presented.Index Terms-ac/dc power converters, converters, dc/dc power converters, electrical engineering education.
