Abstract
The cooperation between the Danish Ministry of Energy and the electric utilities started in 1976 with a joint programme directed towards the development of large wind turbines, their siting and integration in the electric grid. The Tjaereborg wind turbine, a 3-bladed, horizontal axis turbine with the blades placed upwind and full span pitch control for power regulation and with the nacelle placed on a concrete tower, was connected to the electric grid in 1988. It finally came into stable operation in late 1990 after severe technical problems with the control system and gearbox. Rotor diameter is 61.1 m, blade profile is NACA 4412-43, blade length - 29 m, solidity - 5.9%, nominal speed at rated power - 22.36 rpm, tilt angle - 3 deg., hub height - 60 m. The design is based on experience gained from NIBE wind turbines. After 2 1/2 years with serious technical problems, in 1991 the turbine was released for automatic unmanned operation for 10117 hours. The general conclusion is that the electricity-producing wind turbines in the multi MW class are a viable technical possibility although the Tjaereborg turbine represents the wind turbine technology of the early eighties. A detailed technical description of this turbine
