“…The analysis enables verifying if average values of the variable y for many samples are comparable. The analysis of variance was used by many authors such as [1,7,15] usually as a complementary analysis.…”

“…They make use of either the gain matrix (Monticelli and Wu, 1985a,b;Gou andAbur, 2000, 2001) or the measurement Jacobian matrix of the system (Exposito and Abur, 1998;Gou, 2006;Castillo et al, 2005Castillo et al, , 2006Castillo et al, , 2007Solares et al, 2009;Pruneda et al, 2010), which they factorize or transform to extract observability information. Some authors have adopted hybrid techniques (Contaxis and Korres, 1988;Korres and Katsikas, 2003), and other alternative approaches based on mathematical programming techniques have been briefly explored (Habiballah and Irving, 2001;Caro et al, 2013). Of all the available contributions in the technical literature, the algebraic proposal by Pruneda et al (2010) is especially suitable for water networks due to the possibility of simultaneously analyzing the observability of a set of available measurements and the remaining potential measurements in the system.…”

Nowadays, state estimation (SE) techniques are applied to different network systems in order to convert system measurements into real information about the network state. SE applications to water systems are relatively novel, but these techniques have been implemented in other fields for decades. In those applications, observability analysis (OA) is required prior to application of SE techniques with different purposes: i) to identify redundant information, ii) to detect elements that make no contribution in the subsequent SE process or iii) to identify observable islands. However, no discussion has been found in the pertinent literature as regards any interest in applying OA to water networks, with there being only a few basic applications. The aim of this paper is twofold: firstly, to present the implementation of a novel algebraic OA approach to water networks, which is based on the application of a Gauss elimination technique to the measurement Jacobian matrix, and to discuss and justify the interesting aspects of implementing an OA in Water Transport Networks (WTN) prior to using SE whilst also presenting the issues that this technique may resolve.

“…Díaz et al (2015) adaptan del sector eléctrico un método algebraico para el análisis de la matriz jacobiana J, que permite extraer gran cantidad de información. Además, en la literatura propia el sector eléctrico, un referente en la implementación de técnicas de EE y AO, se pueden encontrar una gran variedad de propuestas: métodos topológicos (Krumpholz et al, 1980;Nucera and Gilles, 1991; entre otros), algebraicos (Castillo et al, 2005;Solares et al, 2009; entre otros), híbridos entre los dos anteriores (Contaxis and Korres, 1998;Korres and Katsikas, 2003; entre otros) e incluso otros basados en técnicas heurísticas (Habiballah and Irving, 2001;Caro et al, 2013).…”

<p class="Resumen">Este artículo presenta una técnica alternativa a los métodos existentes en la literatura para el análisis de observabilidad (AO) de redes de agua, paso previo imprescindible para la adaptación de las técnicas de estimación de estado (EE) a estos sistemas. La metodología propuesta parte de un estado de flujo conocido y asume distribuciones aleatorias normales para la incertidumbre de algunas variables hidráulicas, que se propaga luego al resto del sistema. Este proceso se repite a continuación para valorar el cambio en la incertidumbre de la red al añadir aparatos de medida cuyo error se considera nulo, en base al cual se puede evaluar la observabilidad de la red. El potencial del método se presenta mediante un ejemplo ilustrativo, que pone de manifiesto la información adicional que esta metodología aporta con respecto a los enfoques de AO tradicionales. Esta propuesta permite un mejor conocimiento de la red y es una herramienta útil para priorizar la colocación de nuevos equipos de medida, contribuyendo a la transformación de los grandes núcleos urbanos en smart cities.</p>
