This paper presents a study of the influence of doubling the collection grid voltage on the electric resonances in the collection grid of large offshore wind power plants. This was done using wide-band models of most important passive components such as transformers and cables. Wide-band models base...

An electromechanical model of the TotalControl Reference Wind Power Plant has been built. This is based on SINTEF's STAS software, for the system dynamics and control of wind power plants. An overview is given of the theory behind the STAS software, and the architecture of the system model. A wind t...

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-the-art standard models and latest academic developm...

Field solvers are often needed to properly characterize the behavior of grounding structures in a wide frequency range. These solvers provide accurate results but at high computational cost. Design tasks, such as design optimization and sensitivity analysis, require repeated simulations for differen...

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 overvoltages and flashovers in the system during fast...
