Testing a SAS, which involves automation, control and SCADA functionalities, is still usually performed manually. This is not only error-prone but also involves an enormous amount of time due to the increasing complexity of such systems. In substations which make use of IEC 61850 communication, there are now excellent opportunities to perform testing more safely, faster and with higher quality.
In an IEC 61850 substation, all the engineering and configuration data can be saved in standard-format files, the so-called System Configuration Language (SCL) files. In this paper read how you can make use of this important and essential SCL information to replace most of the manual test steps and to improve the process of testing.
