Subsynchronous Torsional Interaction of Wind Farms with FSIG Wind Turbines Connected to LCC-HVDC Lines

Subsynchronous Torsional Interaction of Wind Farms with FSIG Wind Turbines Connected to LCC-HVDC Lines

High-voltage direct current (HVDC) lines with line-commutated converter (LCC) are being increasingly employed to transmit bulk wind power over long distance. However, this may cause the sub-synchronous torsional interaction (SSTI) between the wind farms and the LCC-HVDC system. The SSTI characteristics of wind farms with fixed-speed induction generator (FSIG) wind turbines connected to LCC-HVDC...

HVDC Light for connection of wind farms

There is an increasing amount of wind farms that need to be connected to the AC transmission network. Offshore wind farms will be connected to the ac system via long submarine cables. Integration of offshore wind farms with HVDC transmission based on Voltage Source Converters (VSC), such as HVDC Light, is an advantage due to regulating properties of HVDC Light. The purpose with the Tjæreborg pr...

Impact of DFIG Based Offshore Wind Farms Connected Through VSC-HVDC Link on Power System Stability

With the increased levels of offshore wind power penetration into power systems, the impact of offshore wind power on stability of power systems require more investigation. In this paper, the effects of a large scale doubly fed induction generator (DFIG) based offshore wind farm (OWF) on power system stability are examined. The OWF is connected to the main onshore grid through a voltage source ...

Optimizing the arrangement and the selection of turbines for wind farms subject to varying wind conditions

The development of large scale wind farms that can compete with conventional energy resources presents significant challenges to today’s wind energy industry. A powerful solution to these daunting challenges can be offered by a synergistic consideration of the key design elements (turbine selection and placement) and the variations in the natural resource. This paper significantly advances the ...
