Multi-frequency (or harmonic) emissions and interactions are ongoing challenges for converter-dominated power systems. Consequently, multi-frequency models are introduced for power quality and harmonic stability studies. Rotor-Speed-Dependent (RSD) e

Frequency and sequence couplings can compromise the trustworthiness of multi-frequency models for converter-based systems. There have been effective attempts to address the couplings mainly by linearized averaged models. Only a few studies have been

Proposal for Generic Characterization of Electrical Test Benches for AC- and HVDC-Connected Wind Power Plants

Autor: Ömer Göksu, Behnam Nouri, Vahan Gevorgian, Poul Ejnar Sørensen

The electrical test and assessment of wind turbines (WT) are going hand in hand with standards and network connection requirements. In this paper, the latest developments in the testing of the electrical characteristics of WTs, including IEC standard

Interdisciplinary Analysis of a Turbine Blade With Internal Cooling Including Local Distribution and Rotation Effects

Autor: Knut Lehmann, Arnold Kühhorn, Behnam Nouri

Publikováno v: 11th AIAA/ASME Joint Thermophysics and Heat Transfer Conference.

For the benefit of higher overall thermodynamic efficiency in gas turbine engines, turbine blades are exposed to an increasing high heat load which exceeds the melting temperature of the metal airfoil. Therefore, a system of complex internal cooling
