چکیده

The estimation of flicker emission by a wind park is a complex issue because the network is shared with other loads or generators, even with other wind parks, which contribute to the flicker level. This estimation can be done by means of simulation as depicted in international standards, where the wind turbine generator (WTG) is simulated with a fictitious network, and the results of flicker emission can be extrapolated to a real network. In this paper, modeling and simulation of different WTG technologies are presented. Real measurements from a wind park have been used to validate these models. An approach based in the methodology that appears in international standards is applied for flicker estimation. In this approach, detailed WTG models are used in the estimation. Index terms Wind energy, Wind Turbine Generator, Power Quality, Flicker

Unsynchronized Phasor-Based Protection Method for Single Line-to-Ground Faults in an Ungrounded Offshore Wind Farm with Fully-Rated Converters-Based Wind Turbines

This paper proposes a protection method for single line-to-ground (SLG) faults in an ungrounded offshore wind farm with fully-rated converter-based wind turbines. The proposed method uses the unsynchronized current phasors measured by unit protections installed at the connection point of the fully-rated converter (FRC)-based wind turbines (WTs). Each unit protection collects the unsynchronized ...
