Abstract
In 1978-80 two larger (630 kW) wind turbines were set up at Nibe Bredning (Denmark) supported by the Ministry of Energy and the Danish electricity companies. After they had been used for testing purposes, one of the Danish electricity companies took responsibility for renovating them so that they could be used as a supplementary source of electricity supply for a further 7-10 years. The report describes the retrofitting of these two windmills. The design of the turbines is identical except for the fact that one of them is stall-regulated, the position of the blades is not changed during operation. The rotor had been such that the inner 8 m length of the blades were fixed but the outer 12 m could be turned to some regulated positions. The design of the other turbine was such that the blades could continually be regulated under operation. The outer 12 m in the case of all blades were constructed of glass fiber, whilst the inner 8 m had a supporting steel beam covered with glass fiber parts. The changes made on the blades and hub and on the rotation and control system etc. system are described in detail and illustrated by detailed diagrams
