Abstract
- In the paper an overview of achievements known in the world in the area of construction and application of various electric generator systems for wind turbines is given. Using the available literature and other technical data a comparison is made between the following commonly used types of generator: induction, synchronous with classical excitation, synchronous permanent-magnet and doubly-fed induction generator. A basic concept and some selected details from the design and construction of the first wind generator developed and built in Croatia are given. The generator is three-phase, low speed, 60 poles, designated for direct-drive, power rating 1000 kVA. At rotating speeds between 10 rpm and 30 rpm, the generator voltage and frequency change in the range of 250-690 V and 5-14, 5 Hz. Based on experience acquired by carrying out the first project involving construction of the wind turbine and generator system, the other types of generator are also considered and the optimal solutions are sought for future constructions. Some theoretical and practical significance is given to the possibility and justification for construction of a direct-drive permanent magnet generator, which is estimated to be the most promising technical solution.
