Abstract

This paper presents the voltage signals occurring during a switching operation recorded in the external grid of Gunfleet Sands Offshore Wind Farm recorded with an Elspec measurement system. The measurements are compared to electromagnetic (EMT) simulations for validation of the wind farm model using PSCAD/EMTDC. The simulation model then was modified to investigate the influence of a capacitor bank connection. It was found that for this kind of transients, the amount of wind turbines (wind turbine transformers, high frequency filters and wind turbine converter) included in the model makes a difference to the results; while the cable models (PI or distributed) and the type of model of the wind turbines converter (voltage source or open end), does not have a considerable influence on the transient response at the PCC or MV terminals of the park transformers
