Automação e Supervisão de Manobras de Plantas Didáticas utilizando o Software Elipse Power como SCADA
Arthur M. Diniz;Luiz F. Pugliese;Aurélio L. M. Coelho;José Eugênio L. De Almeida
2023 15th IEEE International Conference on Industry Applications (INDUSCON)
Year: 2023 | Conference Paper |
The use of communication protocols and the choice of variables to be monitored allows the entire system to be in a safer environment, in which an operator has alarms, indicators and a representation of the entire system in real time, avoiding unnecessary exposure in the field, whether in the industrial field or in electrical power systems. In this context, this work intends to contribute to practi...Show More
Comparative analysis of power quality in commercial inverters applied to photovoltaic systems
G. L. Reis;R. M. Silva;P. C. A. Mata;W. W. A. G. Silva;A. L. N. Martins;J. E. L. Almeida;C. V. Sousa
2015 IEEE 13th Brazilian Power Electronics Conference and 1st Southern Power Electronics Conference (COBEP/SPEC)
Year: 2015 | 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.Show More
Wye Apparent Power — An alternative proposal
J. E. L. Almeida;P. M. Silveira;H. Arango;Marcel F. C. Parentoni;J. P. G. Abreu
Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010
Year: 2010 | Conference Paper |
Cited by: Papers (1)
This paper proposes another method of apparent power formulation in time-domain. It intents to be an alternative of the prevalent theories: American (IEEE Std 1459-2000) and European (FBD) methods. This method, called “Wye Apparent Power” is here presented in three different ways in the time-domain: i) using instantaneous values, ii) using collective rms values and iii) using polar coordinates. Al...Show More
Time-domain formulations for apparent power using collective rms and polar coordinates
José E. L. Almeida;Paulo M. Silveira;Hector Arango;Marcel F. C. Parentoni;José P. G. Abreu
Proceedings of 14th International Conference on Harmonics and Quality of Power - ICHQP 2010
Year: 2010 | Conference Paper |
Cited by: Papers (4)
This paper may be considered as a continuation of the paper “A new IEEE Std 1459-2000 - Compatible time-domain formulation for apparent power” published in Electric Power Systems Research from Elsevier. It also presents the development of new time-domain equations related to the definition of apparent power however using collective rms values and using polar coordinates values. These equations giv...Show More
