본문내용

1.1 Wind generator type
① A typical generator (Geared)

② Direct driven generator (Gearless)

※ A typical geared generator
1) Advantages
- Generators can be connected directly to grid
- A simple electrical system
- Less harmonics
- Knowhow

2) Disadvantages
- It operates at constant speed
- A gearbox is needed to transfer the frequency
- Adds to the weight
- Noise
- Demands regular maintenance and increases losses
