6 FAQs about [Generator wind shaft exterior design]

How to choose a wind turbine generator?

Among others is the design of the wind turbine generator. The desired generator should be small and light weight but such design always leads to a tradeoff in the output power aspect , . Permanent Magnet Synchronous Generator (PMSG) and Doubly Fed Induction Generator (DFIG) are most commonly used in wind turbine.

Why do wind turbines need a shaft?

The needed shaft relates to the additional torque and bending moment fluctuations that affect coupling and bearing support design. Such a generator placement increases the overall rotating mass, serviceability, accessibility and allows replacement without wind turbine rotor removal.

Can a vertical axis wind turbine be used with a direct driven generator?

The wind turbine business in the world today mostly revolves around horizontal axis wind turbines with pitch control and a geared generator. Here, the option to use a vertical axis wind turbine with a direct driven generator has been explored.

What is UPSO rotor design for direct-drive wind turbine?

The design of two different power rating (500 kW and 15 kW) exterior rotor PMSG with Unified Particle Swarm Optimization (UPSO) is reported in for direct-drive wind turbine. The main optimization variables are electric loading and maximum value of air gap flux density. There are several constraints. The minimum efficiency is set at 95%.

Why is a generator important in a wind turbine?

The generator is an important component in a wind turbine, since it converts the mechanical energy in the rotating wind turbine to electricity. In this work, the design strategy of adapting the generator to the turbine has been chosen. The turbine is designed with respect to the desired control strategy and the wind conditions at a planned site.

What is a bearing system in a direct drive generator?

Bearings or bearing systems are the critical mechanical component11 in direct-drive generator designs since all wind tur-bine rotor loads are transferred to the tower via bearings to axle/spindle/shaft or generator stator structure.
