This paper presents the steady state analysis of the interconnection of a large Wind Farm (400 MW) to the Brazilian National Grid. Several contingency cases have been simulated to ensure the n−1 reliability standard. Different connection points are analyzed and an economic assessment is developed. All simulations considered the 2015 scenario, when the wind farm should start generation.
This article aims to evaluate the performance of phasor estimation algorithms used in digital relays concerning immunity to the effects of the exponentially decaying dc offset, steady state response and sampling frequency. The algorithms: full cycle Fourier, modified Fourier, cosine filter, modified cosine filter and full cycle Fourier associated with adaptive mimic filter were compared. Two groups...
