Modelling of wind power plant transmission system for harmonic propagation and small‐signal stability studies

Autor: Andrzej Holdyk, Łukasz Hubert Kocewiak, Bjorn Gustavsen, Iván Arana Aristi

Publikováno v: IET Renewable Power Generation. 13:717-724

This study presents the impact of wind power plant components modelling on harmonics propagation and harmonic small-signal stability studies. Different types of cable and transformer modelling techniques are taken into consideration, e.g. state-of-th

Inclusion of Field-Solver-Based Tower Footing Grounding Models in Electromagnetic Transient Programs

Autor: Andrzej Holdyk, Bjorn Gustavsen

Publikováno v: IEEE Transactions on Industry Applications. 51:5101-5106

This paper presents a new approach to wideband modeling of tower footing grounding impedances. Appropriate representation of transmission tower footing impedances is essential in electromagnetic (EM) transient simulations for proper evaluation of ove

Transient voltages resulting from switching operations depend on an interaction between the breaker, the transformer, cables and a neighbourhood grid and imply a risk for the transformer and other components. In this paper the Frequency Domain Severi
