چکیده

The paper presents a comparative analysis on the steady-state behavior of two counter-rotating wind turbines with same components, where generator can operate as (with both mobile rotor and stator— Case ) vs. conventional fixed b electric machine. These energy conversion systems (WECSs) also have coaxial rotors one-degree-of-freedom (1-DOF) planetary speed increaser inputs one or outputs for compatibility considered generator. aims at highlighting efficiency performances WECSs by investigating three functional scenarios (A, B, C) WECS cases ( under assumption identical different rotors. A generalized kinetostatic modeling algorithm is first proposed, starting from general case generator, which allows establishment analytical relationships corresponding to speeds torques input output shafts. Numerical simulations obtained closed-form model in each scenario highlighted influence constructive parameters performances, well energetic superiority WECS, ): higher 1.2% more power 1% (Scenario A) 5.5% C).

Reduction of Cogging Torque in Dual Rotor Permanent Magnet Generator for Direct Coupled Wind Energy Systems

In wind energy systems employing permanent magnet generator, there is an imperative need to reduce the cogging torque for smooth and reliable cut in operation. In a permanent magnet generator, cogging torque is produced due to interaction of the rotor magnets with slots and teeth of the stator. This paper is a result of an ongoing research work that deals with various methods to reduce cogging ...
