History of Wind Power
• BC 5000, 풍력에너지는나일강을따라배를항해하는데사용
• BC 200, 갈대직물날개를한수직축풍차로곡식제분(페르시아, 중동)
단순풍차로물을급수(중국)
• 11 C, 풍차를개량하여호수와라인강삼각주의배수시적용(독일)
• 19 C 후반, 농장과목초지에물을급수하는데사용(미국개척자)
• 1891년풍력발전기의효시 : 덴마크의 Poul La Cour이개발한풍력발전기
=> 가정용과산업용전기를생산하는데이용
• Grandpa’s Knob : 1940년대제일큰풍력터빈
- 미국 Vermont 주언덕의정상에서작동되기시작
- 1.25 MW 출력 @ 48 km/h
- 2차 세계대전 중 수개월 동안에 지역 전기공급망에
전기를 공급

Evolution of Wind Turbine Generator Systems
FSIG wind turbines were applied to wind turbines as large as 1.5 MW.
There are increasing difficulties in controlling drive train oscillations and limiting mechanical load.
FSIG wind turbines have difficulties meeting the requirements of the Grid Codes.
DFIG became increasingly common in large wind turbines where the benefits of limited variable-speed operation
were required but at the reduced cost of controlling only a fraction of the output power.
Slip rings are required on the generator roto and the air-gap of a wound rotor induction generator must be kept small.
FPC overcomes these problems, but it is expensive
