Estimation of Synchrophasors in Intelligent Electrical Networks: from Models to Design Restrictions

We first present a detailed review of two popular classes of model based synchrophasor estimators. They are the discrete Fourier transform (DFT) and the Taylor-Fourier transform (TFT) class estimators, which arise from constant or polynomial phasor models, respectively. Limitations of these techniqu...

They are the discrete Fourier transform (DFT) and the Taylor-Fourier transform (TFT) class estimators, which arise from constant or polynomial phasor models, respectively. Limitations of these techniques, arising from the models themselves, are exposed. These limitations make the original DFT and TFT approaches unfitted for situations where the phasor can not be properly described in such simple terms. This issue can be addressed with the recently introduced convex semi-infinite programming (CSIP) based estimators, which are also reviewed. In particular, we present the constraints associated with the tests which are most critical for the model based methods, showing how to precisely control the estimators performance in those cases. Finally, we show that the DFT and TFT estimators are particular instances of the CSIP estimator, so that there exists a connection between these two apparently different approaches. This opens the door for future analyses and developments. Presentamos en primer lugar una reseña de dos populares clases de métodos de estimación de sincrofasores. Ellas son la clase de métodos basados en la transformada de Fourier discreta (DFT) y la transformada de Taylor-Fourier (TFT), que surgen de un modelo de fasor constante y polinómico, respectivamente. Se exponen las limitaciones de estos métodos, que surgen por los propios modelos asumidos, lo cual los hace poco apropiados en situaciones donde el fasor no puede representarse en términos tan simples. Este problema puede resolverse con los estimadores basados en optimización convexa semi-infinita (CSIP), un enfoque novedoso que también es descripto. En particular, enfatizamos las restricciones asociadas con las situaciones más críticas para los métodos basados en modelos, mostrando cómo controlar precisamente el desempeño de los estimadores en dichos casos. Finalmente, mostramos que los estimadores DFT y TFT son instancias particulares del estimador CSIP, de modo existe una conexión entre estos dos enfoques aparentemente diferentes. Esto abre la puerta para futuros análisis y desarrollos. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/26 10.37537/rev.elektron.1.2.26.2017 spa FIUBA https://elektron.fi.uba.ar/elektron/article/view/26/32 https://elektron.fi.uba.ar/elektron/article/view/26/159 Derechos de autor 2017 Francisco Javier Messina, Leonardo Rey Vega, Cecilia Gabriela Galarza Elektron Journal; Vol. 1 No. 2 (2017); 79-90 Revista Elektron; Vol. 1 Núm. 2 (2017); 79-90 Revista Elektron; v. 1 n. 2 (2017); 79-90 2525-0159 2525-0159 PMUs DFT TFT CSIP PMUs DFT TFT CSIP Estimation of Synchrophasors in Intelligent Electrical Networks: from Models to Design Restrictions Estimación de Sincrofasores en Redes Eléctricas Inteligentes: de Modelos a Restricciones de Diseño info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=26_oai
