IET Digital Library: Electrical generators for direct drive wave energy converters …
Electrical generators for direct drive wave energy converters. Wave power devices traditionally use conventional rotary electrical machines for power conversion. However hydraulic systems or air turbines are required to convert the low reciprocating motion of the wave device to rotation at 1500 rpm. The concept of a direct drive system is ...
Optimum 7 MW HTS direct-drive wind turbine synchronous generator …
Partially superconducting direct-drive wind turbine generators with high-temperature superconducting excitation winding enable an increase of the rated unit power, higher efficiency, and a high, adjustable power factor. The high excitation ampere-turns allow for iron topologies that differ from conventional permanent magnet-excited generators. …
Energies | Free Full-Text | Cooling Techniques in Direct-Drive Generator…
Direct-drive generators are an attractive candidate for wind power application since they do not need a gearbox, thus increasing operational reliability and reducing power losses. However, this is achieved at the cost of an increased generator size, larger inverter and decreased thermal performance. The associated cooling system is …
A 5MW direct-drive generator for floating spar-buoy wind turbine: …
This work forms the first of a two-part investigation aimed at identifying the challenges and opportunities of implementing a direct-drive generator for a spar-buoy type floating wind turbine. Preliminary specifications are presented for a fully coupled aero-hydro-servo-elastic model of a floating wind turbine with a 5 MW direct-drive generator. The …
Detailed Design Procedures for PMSG Direct-Driven by Wind …
This paper is committed to show a well-ordered system used to design a permanent magnet synchronous generator (PMSG). The fundamental focus of this work is the generators which are in gearless configuration, and in the fragmentary or couple of kilowatts power range. A straight lumped-component based model is introduced, which is …
Direct Drive Wind Turbine – Net Zero Guide
Direct drive refers to a type of wind turbine design that eliminates the gears in a conventional wind turbine. In a conventional, gear-driven turbine, the rotor blades spin a shaft which drives gears that drive a generator a direct drive design, the drive shaft spins the generator directly, causing it to spin at the same speed as the turbine blades.
