The adequacy of the present practice in dynamic aggregated modelling of wind farm systems [PDF]

open access: yes, 2016
Large offshore wind farms are usually composed of several hundred individual wind turbines, each turbine having its own complex set of dynamics. The analysis of the dynamic interaction between wind turbine generators (WTG), interconnecting ac cables, and

Mitigation of cross-saturation effects in resonance-based sensorless switched reluctance drives [PDF]

open access: yes, 2010
The stator and rotor yoke in a switched reluctance motor form magnetic circuit parts that are typically shared by different phases. If these parts saturate due to the excitation of one phase, this will lead to a change of the magnetic characteristics of ...

Very long distance connection of gigawatt size offshore wind farms: extra high-voltage ac versus high-voltage dc cost comparison [PDF]

open access: yes, 2016
This study presents a cost comparison between commercially available high-voltage DC (HVDC) and extra high-voltage AC shore connection (±320 kV voltage source converter and 420 kV-50 Hz single-core and three-core cables), for a 1 GW offshore wind farm ...

Power Quality Improvement using Voltage Source Converter (VSC) based Unified Power Quality Conditioner (UPQC)

open access: yesInternational Journal of Computer Applications, 2016
recent years, there is tremendous growth in the use of power electronic devices in every sphere but in nonlinear loads, it has problem of drawing the two important limitations; draws the non-sinusoidal current and reactive power from source which in turn effects the power quality.

Hybrid HVDC for supply of power to offshore oil platforms [PDF]

open access: yes, 2004
A HVDC hybrid system, comprising a line commutated thyristor HVDC converter and a STATCOM, is proposed in this paper for supplying power to offshore oil platforms that do not have their own generation. The proposed system combines the robust performance,

Generalized Voltage-based State-Space Modelling of Modular Multilevel Converters with Constant Equilibrium in Steady-State [PDF]

open access: yes, 2017
This paper demonstrates that the sum and difference of the upper and lower arm voltages are suitable variables for deriving a generalized state-space model of an MMC which settles at a constant equilibrium in steady-state operation, while including the ...
