A wind turbine is a conversion mechanism that converts energy into electrical energy, but the efficiency cannot reach 100%, so there partial loss. These losses are converted thermal which in turn causes to heat up and affect generator performance. Therefore, cooling temperature field analysis of turbines very important. In this paper, an electromagnetic model established by using parameters 4 M...

This paper proposes a method of applying the Space Vector Modulation technique for Direct Torque Control (DTC) of a permanent magnet synchronous motor (PMSM) drive. By this method it is preserved the principle of the conventional DTC regarding the decoupled torque and flux control, while providing more flexibility for the inverter voltage utilization, in order to compensate the torque and flux ...

Abstract Partially superconducting direct-drive wind turbine generators with high-temperature excitation winding enable an increase of the rated unit power, higher efficiency, and a high, adjustable power factor. The high ampere-turns allow for iron topologies that differ from conventional permanent magnet-excited generators. This study compares four different $$7\,\mathrm{MW}$$ <mml:math xmlns...

In renewable power generation the wind energy has been noted as the most rapidly growing technology; it attracts interest as one of the most cost-effective ways to generate electricity from renewable sources. Wind generation system has potential application for the grid support. The voltage of the direct driven permanent magnet wind generators (PMSG) is variable due to the intermittent nature o...

There are different configurations selected by both industry and academia as the drivetrain for wind turbines in power range of 10 to 16 MW. The choice system influences levelized cost energy, and, become larger, therefore, costlier, there is more potential optimization critical systems, like drivetrain. latter motivates utilization a life cycle assessment approach profoundly influence technolo...

Direct-on-line (DOL) driven permanent-magnet generators (PMSGs) are often applied in small-scale hydropower plants (< 10 MW). The Commission Regulation (EU) 2016/631 defines the boundary conditions to operate these parallel with grid. According regulation, fault-ride-through (FRT) capability is required some cases. FRT scenario of PMSGs was studied by simulations and importance machine paramete...

Removing the gearbox from single-motor configuration of an electric vehicle (EV) would improve motor-to-wheel efficiency by preventing mechanical losses, thus extending autonomy EV. To this end, a permanent-magnet Vernier machine (PMVM) is designed to ensure such operation. This avoids high volume and large pole-pair number armature winding since its operating principle resembles that synchrono...
