The growing global demand for electricity from renewable sources is increasingly encouraging the adoption of solar plants. However, due to the variant nature of solar irradiance, brought about by atmospheric phenomena, ...

This work presents the development and implementation of an application in the Android operating system for Total Sky Imager. Commercial equipment has a high cost so that its acquisition by the IFPE campus Pesqueira is ...

A performance analysis can be done in more than one way, either through manual calculations and measurements or using software and centralized monitoring devices, which is the case of this study. The main objective of ...

The use of wind energy has grown exponentially in the last decade, especially in Brazil, which provides regions with great availability of wind and space. The capture of energy through the winds is carried out by wind ...

In contrast with the environmental problem, the global power of electrical energy is increasing, demanding energy transitions from the energy supply sectors toward more efficient and less polluting energy sources. In ...

The distribution system grows continuously thus increasing the probability of the emergence of faults in its lines. In order to solve this problem was developed a program that can, through the RMS values of the electrical ...

Grid-Connected Photovoltaic Systems (SFCRs) significantly propose the expansion of renewable energy sources in the national electricity matrix. These systems can have their energy performance selected through Figures of ...

This work presents a study on protection requirements regarding the Transient Recovery Voltage (TRV) for circuit breakers and reclosers on a power system distribution network. In view of the growth of changes in the Electric ...

The increased interest in renewable generation projects brought to the energy market a concern regarding the ability of the Brazilian Interconnected System (SIN) to carry out the energy produced by these new plants. This ...

In Brazil, distributed generation has grown significantly in recent years. Although a large portion of electricity generation is centralized, mainly through hydroelectric power plants, the landscape is changing, and ...
