Abstract
The disclosure relates to phasor-based monitoring, protection and control applications in electric power systems supervised and/or managed by a Supervisory Control And Data Acquisition/Energy Management System (SCADA/EMS). In order to enable the applications without incurring heavy infrastructural investments, a phasor measurement facility is integrated into a Remote Terminal Unit (RTU) that is part of the SCADA/EMS system and comprises Input/Output (I/O) interfaces hard-wired to a substation of an electric power system. By taking advantage of the fact that RTUs as indispensable building blocks for any SCADA/EMS are part of every substation of the power system, no extra housing, cabling and EMC shielding for the additional functionality needs to be provided.
