This Course Conclusion Thesis consists of making and maintaining a connection in which information is sent from a SCADA server to a recloser, a fundamental element for the smart grid. After that, both the general workings and concept of the system in question, will be introduced. To accomplish the task of transferring information from a SCADA server to a recloser, the DNP3 communication protocol was used. This element will also be explained further as all the layers of communication that exist throughout the procedure will be tackled. This project also consists of simulating this described system. Utilising software acquired online, it was possible to remotely operate a recloser simulator. Furthermore, this simulation of the communication between the recloser and the SCADA server was both observed and documented, facilitating the link between the theory described in this thesis what is to be expected in real world applications. It is noteworthy that, due to the difficulty of maintaining the recloser simulator software (only the temporary version was acquired), a SCADA-Arduino system was implemented, utilizing the Modbus Serial communication, so that it would be possible to grasp in a deeper way the full behaviour of a SCADA operation.
