Engineering Design Process – the basis for simple SAS testing

Abstract—During the life cycle of a Substation Automation System (SAS), testing the communication, interlocking logic and proper operation of all signals transmitted to Supervisory Control and Data Acquisition (SCADA) systems take considerable effort and time. In a substation which makes use of IEC 61850 communication, all the engineering and configuration data can be saved in standard format files, the so-called System Configuration Language (SCL) files.
