Abstract. This work presents study details of a biomass based electricity generation project. The biomass used was industrial poultry litter. The objective of the work is to contribute to the research of poultry waste use in real life applications. In this sense, a case study is presented. The case study is an aviary industry region of southern Brazil, where is evaluated the technical and economic characteristics of power generation using biomass obtained from poultry litter. Still, it is highlighted the large energy potential and the high poultry litter production in the region, which translates into a important source of raw material for electricity generation, currently not highly explored in Brazil.
The wavelet transform has received great importance in the last years on the power system analysis because the multi-resolution analysis presents proprieties good for the transient signal analysis. This chapter presents a review on main application of wavelet transform in electric power systems. The study areas have been classified as power system protection, power quality disturbances, power system transient, partial discharge, load forecasting, faults detection, and power system measurement. The areas in which more works have been developed are the power quality and protections field, where both cover 51% of the articles analyzed.
This paper presents the main features of design, construction, performance analyses and experimental studies of a brushless self-excited three-phase synchronous generator. The basic construction, principle of operation, and exciting characteristics are described. In proposed machine the rotor winding is shorted through diodes and the self-excitation is reached by a slip between rotor and stator winding built with different pole numbers. Computer simulations performed with MATLAB® software were used to verify the mathematical model of the brushless self-excited synchronous generator and the achieved results showed similar behavior with experimental values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
