Evaporative cooling system has the advantage of high cooling performance, good insulation properties, less electrical fault, easy to maintain and high reliability, can meet the requirements of the cooling system in wind power generators. Based on a large number of theoretical researches and engineering practices, we had a comprehensive study of evaporative cooling wind power generator. Studies show...
Both 2D and 3D magnetic field finite element simulations of 3.6MW permanent magnet synchronous wind generator (PMSWG) are done in this paper and the 2D simulation results of no-load voltage, load voltage and current are compared with that of 3D simulation. Meanwhile, the leakage flux coefficient, skew slot effect and end leakage reactance are analyzed according to this 3.6WM generator design project...
Turbo generator with evaporative cooling stator and water cooling rotor possesses many excellent qualities for mid unit. The rotor bars are cooled by water inner cooling mode. The stator bars and core are immerged in evaporative coolant, which could be cooled fully. This paper presents the study of heat-transfer with different features in the turbo generator, and analyzing it by CFD. Finally, the...
The 2D model of direct drive permanent magnet wind turbine 3 MW, 660 V, 14 rpm is set up to study the magnetic field by finite element method. Based on Maxwell equations, parameters are obtained in the case of static field, no load and load transient operation. The post processing is help to validate and optimize the design of the generator.

Higher power density has been an important goal in the field of power generator. Using evaporative cooling system has made a great progress in making smaller and more powerful generator. As this new technique could improve the cooling effect so that the current density of windings could be set higher and smaller cubage would not bring superheating. It is a great progress, but the slots in the stator...
The optimal design of a 2.4 MVA high temperature superconducting (HTS) generator is presented. The main features of its configuration are the adoption of the evaporative cooling stator and the magnetic flux oriented rotor. The cross section of the field winding in rotor is in circular arch shape, and the magnetic diverter shims are embedded between HTS coils. The technical and economical parameters...
