Objective
Objectives
The objective of the project is to finalise the design, manufacture, operate and evaluate a 500 kW wind turbine with a directly driven generator distinguished by permanent magnet excitation and modular stator and rotor elements. The generator will be tested both in laboratory and in the turbine.
The project consists of the following tasks: 1. General design and manufacture.
2. Final electrical design of generator.
3. Electrical system (less generator) and control.
4. Generator design and manufacture.
5. Generator testing and electrical modelling.
6. Evaluation.
Technical approach
The proposal is based on an earlier Joule2 project, which was conducted in co- operation with six European universities and one private company. After an evaluation of the five candidate designs, one proposal was selected for a final design of a 500 kW generator and the application of an available conventional 400 kW wind turbine design to this generator. The project included building of a 40 kW test generator of the selected concept..
The generator design is characterised by modular rotor and stator elements, that may be produced in quantity without any large scale facilities. The magnets are of ferrite type furnished with laminated iron flux concentrators.
The stator elements consist of an E-core lamination with a single coil. The design is protected by a patent.
The generator is connected to the grid by means of an AC-DC-AC link.
Expected achievements and exploitation
In general the project will be carried out as an ordinary industrial wind turbine development project including design, manufacture, erection, commissioning and evaluation. The main difference is that the project also includes the development of the directly driven generator and its electrical and control systems.
The prototype unit will be erected at the site of the present 400 kW Nordic prototype. Equipment from the former unit will be used in the project as far as is practical and economical. E.g. the former machinery and electrical equipment is planned to be utilised for furnishing the high torque and low speed required for testing the generator in the laboratory.
When the evaluation is completed, necessary steps will be taken to put the generator and the directly driven wind turbine into commercial production.
This will include a relevant marketing effort. The further upscaling to larger commercially relevant sizes will benefit from the modular design of the generator. Results of general interest will be published in scientific journals and at conferences.
