Compatibility Between Electric Components in Wind Farms

The paper describes a method for investigation of the compatibility between electric components in wind farms by identifying critical resonances at different points of an offshore wind farm (OWF), based on systematic variation of critical parameters. In this way, the design of future OWF can be improved at a very early stage of the process.

It is also revealed what parameters are the most important ones when considering compatibility. It was observed that a change of capacitance in the collection grid shifts the resonance peaks. A change in WT transformer capacitances influences the admittance at higher frequencies only. No influence was observed of change of X/R ratio of 132 kV grid on the admittance characteristic at any observed location in the farm.
