Final report on development and building of DANmark 36, 525 kW wind turbine situated at Hanstholm. Edition 2

摘要

A description of the development and construction of the DANmark 36, 525 kW wind turbine located at Hanstholm in Denmark. The turbine was developed in order to prove that its operational economy was at the same level as smaller wind turbines. This objective was fulfilled. It is claimed that, in order to cut down on costs, untraditional measuring methods were used and these are described. The site is characterized as roughness class 1, equivalent to a calculated annual production of 1.280.000 kWh. The key figures for a 150 kW wind turbine (July 1993) on a site of roughness class 1 is ca. 2.2-2-6 DKK /kWh/yr. For the 525 kW wind turbine the key figure is 2.2 DKK/kWh/yr. The technology, design, control and safety systems, site, cost and financing, wind turbine dynamic response, air brake test, computerized control system, instrumentation problems, control of the strain gauges on the main shaft and the calibration of the wind turbine are all described. It is claimed that the uncomplicated construction of the wind turbine makes it suitable for local production. (AB)
