Grid modelling for wind farm harmonic voltages evaluation

A prospective wind farm consisting of 21 turbines with 2 MW double-fed induction generators is planned to be connected to a 110 kV substation in distribution system.

In this case study, different network configurations are modelled.

The influence of the accuracy of grid modelling on grid harmonic impedance characteristic at a particular point is analysed, and a comparison of the results is done for the different network configurations.
