Kriegers Flak 640 MW Off-Shore Wind Power Grid Connection-A Real Project Case Study

This paper reports on the feasibility study performed to investigate the possibilities of connecting the 640-MW off-shore wind power farm, planned for Kriegers Flak 30 km south of Trelleborg, to the E.ON 130-kV subtransmission system. The Kriegers Flak commissioning is planned for 2010. The aim of t...

Description
Summary:This paper reports on the feasibility study performed to investigate the possibilities of connecting the 640-MW off-shore wind power farm, planned for Kriegers Flak 30 km south of Trelleborg, to the E.ON 130-kV subtransmission system. The Kriegers Flak commissioning is planned for 2010. The aim of this 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 of three major parts: fault current calculations, load flow calculations, and dynamic simulations. The study shows that it is possible to connect such a large off-shore wind power farm to the 130-kV subtransmission system, but reinforcement concerning load currents during normal operation and fault currents have to be made
