Abstract
Este proyecto aborda el estudio del sistema de control en una subestación, más concretamente la captura de datos desde el parque hasta la sala de control. Actualmente esta captura de datos se realiza mediante cable de cobre y en este proyecto se abordará la comunicación de seccionadores e interruptores mediante comunicación Ethernet. Este sería un nuevo avance en el control de la subestación ya que se introducirá en ella el Bus de Campo de la misma forma que ahora está el Bus de la Estación. Para ello se estudiarán los protocolos de comunicaciones más utilizados dentro de la industria y se analizará su viabilidad dentro del sistema de control de la subestación. También se estudiará la Norma 61850 que es específica para las comunicaciones dentro de las subestaciones y cómo se puede aplicar esta norma para el Bus de Campo. Con el estudio técnico económico de esta nueva configuración se pretenden llegar a una solución tecnológicamente más sencilla. Una solución en la que los costes sean menores ya que se puede reducir de forma considerable la cantidad de cobre empleado dentro de la subestación, disminuyendo no solo los costes de material sino también los costes de montaje, cableado y mantenimiento de la misma. _____________________________________________________________________________________________________________________
This project approaches the study of the system of control in a substation more concretely the capture of information from the field to the control building. Nowadays this capture of data is realized by means of wire copper and in this project there will be approached the communication of Switch and circuit breaker by means of communication Ethernet. This one would be a new advance in the substation control since the field bus will get in it in the same way as now the bus of the station is. For it will be studied the protocols of communications most used in the industry and its viability was analyzed in the system of control of the substation. Also it will study the 61850 standard that it is specifically for the communications inside the substations and since as this standard can be applied to the Field bus. With the technical economic study of this new configuration they try to reach a technologically simpler solution. A solution in which the costs are minor since it is possible to reduce of considerable form the quantity of copper used inside the substation, reducing not only the costs of material but also the costs of assembly, wired up and maintenance of the same one.
