SAS can realize comprehensive automatic control functions (including automaticn supervising, measurement, control, protection and dispatcher communication, etc.) on main equipment in transformer station and transmission & distribution lines by using advanced computer technology, modern electronic technology, communication technology and signal treatment technology. Xinhua XISCS-SAS is a typical example of the application of SAS. It provides the transformer station of rail traffic with a complete solution by integration of data acquisition, image-supervising, control, protection and metering. Following figure is a typical configuration of automation system for combined substation of rail traffic based on Xinhua XISCS-SAS:
