Detailed modeling for large scale wind power installations - a real project case study

This paper reports on the modeling issues performed related to a feasibility study to investigate the possibilities to connect the 640 MW off-shore wind power farm, planned for Krieger’s Flak 30 km south of Trelleborg (Sweden), to the E.ON 130 kV subtransmission system. The aim of the entire study is to answer the question if such a connection is possible, and under what conditions; it is not meant as a design project. Following a general connection design discussion, the study comprises three major parts, fault current calculations, load flow calculations, and dynamic simulations. Concerning the modeling aspects, much effort has been put on details and scalability for the dynamic simulations.
