Some grid codes establish that during voltage sags, the generation units employing static converters must favor the electrical mains support. Unbalanced voltage sags generate grid power oscillations with twice the fundamental frequency. This way, the converter control can be modified to mitigate the unbalanced sag effects to the grid converter. The...
Conference Paper
The growing use of wind energy conversion systems around the world is pushing the individual power of wind turbines to higher values. Especially in offshore farms, where installation and maintenance have higher costs, high power wind turbines and their reliability become critical issues to make investments economically viable. In this context, mult...
Conference Paper
This article proposes the analysis of the quality of the power provided by two commercial photovoltaic inverters. Initially the inverters are analyzed based on the recent regulations, afterwards the equipment is compared based in the measurement of the distortion rates and power factor during the analyzing period.
Conference Paper
Resumo - The usage of electrical energy generation with alternative sources is increasing significantly, due to the general concern about the environment and generation with nonrenewable sources. This fact encourages the development of technologies and new researches, to come up with solutions to allow the connection the new systems to the grid in...
