Kalki SCL Manager Substation Configuration
Software Platform enables substation engineers and design and
commissioning engineers to build different substation configurations,
architectures, models etc., quickly and cost effectively, without being
to be experts in IEC 61850.
SCL Manager is a comprehensive
graphical tool that allows user to create, configure, view and edit all
the substation elements and its data models as specified in Substation
Configuration Language specification of IEC 61850. SCL Manager enables
users to configure a Sub-station and all its elements and make
substations IEC 61850 compliant.
SCL Manager takes away the
complexity of the IEC 61850 from the user and gives user friendly
graphical interface for configuration and substation architecture
definition. It allows users to build different substation architectures,
and create complete system specifications. SCL Manager also allows user
to link different IEDs & its data elements to the substation
specification and create complete substation configuration as specified
in IEC 61850.
Facility is given for creation of complete IED
capabilities including its functions and data elements for any new IEDs.
SCL Manager enables defining communication schemes and mapping data as
required for management of IEC 61850 elements. It also facilitates
enhanced management of SCL files and its validation. The enhanced
logical node template allows user to create complete functionalities of
IEC 61850 based IEDs with a very minimal knowledge of IEC 61850
standard.

Intelligent electronic device
IEDs receive data from sensors and power equipment, and can issue control commands, such as tripping circuit breakers if they sense voltage, current, or frequency
anomalies, or raise/lower voltage levels in order to maintain the
desired level. Common types of IEDs include protective relaying devices,
On Load Tap Changer controllers, circuit breaker controllers, capacitor
bank switches, recloser controllers, voltage regulators, etc.
Digital protective relays are primarily IEDs, using a microprocessor to perform several protective, control, and similar functions. A typical IED can contain around 5-12 protection functions, 5-8 control functions controlling separate devices, an autoreclose function, self monitoring function, communication functions etc. Hence, they are aptly named as Intelligent Electronic Devices.
Some recent IEDs are designed to support the IEC61850 standard for substation automation, which provides interoperability and advanced communications capabilities.

Generic Substation State Events (GSSE)
Generic Substation State Events (GSSE) is an extension of event
transfer mechanism in UCA2.0. Only Status data can be exchanged through
GSSE and it uses a status list (string of bits) rather than a dataset as
is used in GOOSE. GSSE messages are transmitted directly over IEC/ISO
8802-2 and 8802-3 using a similar mechanism to GOOSE messages (refer IEC
61850-7-1 Clause 12.2, IEC 61850-8-1 Clause 6.4). As the GSSE format is
simpler than GOOSE it is handled faster in some devices. GSSE is being
progressively superseded by the use of GOOSE and support for it may
eventually disappear.
