This will have Substation part, Data type templates and logical node type definitions but need not have IED section. Substation Configuration Description (SCD) file: This is the file describing complete substation detail. It contains substation, communication, IED and Data type template sections.
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations.It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems. [1]
CIM and Substation Configuration Language (SCL) are developed in parallel under different IEC TC 57 working groups. Though both have the ability to exchange model and configuration information between different equipment or tools and use XML for storage, many differences separate the standards: CIM is based on UML, using inheritance.
Generic Substation Events (GSE) is a control model defined as per IEC 61850 which provides a fast and reliable mechanism of transferring event data over entire electrical substation networks. When implemented, this model ensures the same event message is received by multiple physical devices using multicast or broadcast services.
COMTRADE files are typically generated by Intelligent Electronic Devices , such as an electronic protective relay, in electrical substations during power systems disturbances. These IEDs monitor the electrical characteristics of the power system by digitally sampling measurements of the current , voltage , power , frequency , etc. at a high speed.
When power outages occur, you may hear officials use unfamiliar words as they explain the situation or provide updates. We explain a few common terms.
Substation integration refers to combining data from the IED's local to a substation so that there is a single point of contact in the substation for all of the I&C data. Power-system automation processes rely on data acquisition; power-system supervision and power-system control all working together in a coordinated automatic fashion.
An XML-based device and profile description language is specified for I/O device configuration. SDDML (Sercos Device Description Markup Language) describes which profiles are supported by a certain device. SPDML (Sercos Profile Description Markup Language) is used to specify the different profiles based on the Sercos parameter model.
