Exploring SCD File Configuration
The understanding of Substation Configuration Language (SCL) will be incomplete without delving into the details of its file configurations, particularly the Substation Configuration Description (SCD) file configuration.
The Essence of SCD Files
SCD files represent the linchpin of the SCL, encapsulating the complete configuration details of a substation. These files embody not just information on integrated devices (IEDs) and their related data, but also the details of every service and communication system within a substation.
In simple terms, the SCD file shows an entire map of the substation, including detailed documentation of all its elements – a feature that streamlines system integration processes and helps ensure consistency across the power networks.
