Drift, utveckling och dokumentation vid Chalmers provstation för vindenergiforskning

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The objective of the project is to carry out research, maintain and run the Wind Turbine at the Hönö test station. Another objective of the project is to make documentation and measurements available on the web. The station is used in research projects as well as a demonstration and a lab facility. The turbine is equipped with a permanent magnet direct driven generator and an electrical system with a DC link suited for variable speed operation. Research is focused mainly on the generator and its electrical system. In this study the generator electrical system has been rebuilt for series compensation. An investigation of series compensation of the PM generator has been made in an earlier study. (”Drift av Hönö provstation – HÖNÖ”, Chalmers, December 2006) That earlier study showed that the use of capacitors in series with the generator windings in comparison to parallel capacitors could increase the power output from the generator by 60%. Measurements made on the rebuilt electrical system confirm this. Several study visits and an Open House are arranged annually. The test station is financed by Göteborg Energi. The report is made within the project ”Drift, utveckling och dokumentation vid Chalmers provstation för vindenergiforskning”.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The objective of the work at Chalmers test station is to carry out research, maintain and run the wind turbine at the plant. The station is used for research projects and as a demonstration and lab facility. The turbine is equipped with a permanent magnet direct-driven generator and an electrical system with a DC link suited for variable speed operation. Research focuses mainly on the generator and its electrical system. Series compensation of the PM generator is investigated. Theoretical studies show that the use of capacitors in series with generator windings in comparison to the present parallel capacitors can increase power output from the generator at a certain design speed interval. Both theoretical calculations and practical tests show that an increase in power by 60 % is possible.

Konferensbidrag (refereegranskat)abstract
- Voltage-oriented control (VOC) of a three-phase PWM rectifier is one of the widely used structures in active converters. Design, simulation results, an FPGA implementation, and practical results of a VOC based three-phase PWM boost rectifier are presented and explained in this paper. National Instruments CompactRIO programmable automation controller platform is utilized in this application. The developed software and implemented hardware based on this controller are presented for this application.

Wind Power is a Breeze
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- As a part of the international science festival in Göteborg, Sweden, the experimental workshops welcomed over 10 000 visitors for a period of two weeks. During the weeks, students aged 8-15 visited the workshops and during the weekends the public joined in. At the workshop “Wind Power is a Breeze” students were able to construct their own turbines for a miniature wind power station and thereby learn about wind power. There were two turbines, a smaller one intended for the younger children and a larger one intended for the older ones. The small one was connected to a little model house with a light bulb and the larger one to three lamps connected in parallel plus a volt meter, ammeter and oscilloscope. The station was appreciated by the visitors, pupils as well as researchers. The station can be further improved and may be useful in laboratory practicals intended for older students.The work was carried out within the EU-project Power Cluster in The Interreg IVB North Sea Region Programme.
