Abstract-With a move to 'smarter' distribution networks through an increase in distribution automation and active network management, the volume of monitoring data available to engineers also increases. It can be onerous to interpret such data to produce meaningful information about the health and performance of automation and control equipment. Moreover, indicators of incipient failure may have to be tracked over several hours or days.This paper discusses some of the data analysis challenges inherent in assessing the health and performance of distribution automation based on available monitoring data. A rule-based expert system approach is proposed to provide decision support for engineers regarding the condition of these components. Implementation of such a system using a complex event processing system shell, to remove the manual task of tracking alarms over a number of days, is discussed.

“…La desventaja que se ha observado en dichos estudios es que la representación de la base del conocimiento se empieza a hacer más tediosa de aplicar conforme la red de transporte se hace más grande en número de componentes y al emitir un diagnóstico para fallos simultáneos y múltiples [Bi02], [Negnevitsky05], [Huilan05], es decir que el estado lógico de un número mayor de interruptores y esquemas de protección deberá de ser tomado en cuenta, para la emisión de un diagnóstico correcto para cada uno de los componentes de la red de transporte, que en algún momento se encuentren sujetos a fallo.…”

Dedicated to Prof. Dr. Thomas Hirth on the occasion of his 60th birthday PtX technologies are one major building block of the future energy system based on renewables sources. Dimethyl ether (DME) is an important PtX product that can be used as intermediate the production of CO 2 -neutral base chemicals. New applications lead to an increase of the global production and the optimization of the process efficiency, especially when considering decentralized synthesis. This review article puts some spotlights on recent developments in methanol and the direct DME synthesis with a special focus on the modeling and bifunctional catalyst. This study is expected to provide a foundation for future works in the field of catalysis research based on catalysts design and kinetic modeling.
