Modeling of the energizing of a wind park radial
Paper in proceedings, 2007

This paper presents measurement and modeling of the energizing of a wind park radial. The measurements in this paper are taken from the Utgrunden wind park that consists of seven wind turbines each of 1.5 MW rated power. This park is connected to the Ă–land 55 kV grid at the Degerhamn station. The wind turbines in the Utgrunden wind park are of the pitchregulated doubly-fed induction generator (DFIG) type. The transient voltage and the energizing current graphs are presented and both active and reactive powers are analyzed as the radials to the wind park is connected. Furthermore, the model of the Utgrunden wind park radial is built using PSCAD/EMTDC software. For the cable model, the frequency-dependent (phase) model built in model is used. A built-in model with the saturation modeling is simulated for the purpose of the transients analysis and the results are compared with measurements. The results show that the measured resonance frequency agrees well with the measurements while the damping is underestimated in the simulations.
