Abstract

The aim of this paper is the implementation and validation of a mobile phone remote connection to a Supervisory Control and Data Acquisition system (SCADA) of a railway traction substation. The implementation was done not only to optimize the time in which the user intervenes within the electrical substations, in case of a fault or other event, but mostly to be able to react in unforeseen situations where the person in charge is not and cannot quickly reach the electrical substation or even the remote desktop. For this, the operator can connect to the system using the mobile phone and the corresponding mobile phone software using an interface similar to the remote desktop. Therefore, the operator can hand the fault and make the required actions or improvements. The proposed system gives the ability to optimize the intervention costs considering the required trips to the electrical substation, and even more the trip to the SCADA remote desktop station. Therefore, a wireless remote connection method is approached via the mobile phone network to the SCADA system.
