Vendor-specific implementation
3.1
615 series implementation
IEC 60870-5-103 is specified for single function protective equipment with a
limited set of process data. Extensions that are necessary for supporting the 615
series IEDs are:
•
Multiple protection functionality
•
4-pole objects (objects with four valid positions, that is, circuit breakers,
disconnectors)
•
Circuit breaker and disconnector control operations
•
Class 1 event overflow handling
Since these features are not a part of the IEC 60870-5-103 standard, it is not likely
that different vendors have implemented them in the same manner. However, it is
guaranteed that IEDs in the 615 series are equally implemented concerning these
features. In addition of having 615 series-specific default settings for private
function type and information number application data definitions, the user can
reprogram these settings if required. The user can also affect the way in which
Class 1 event overflows should be treated and reported.
ASDU type 2 data is generally supported. This means the generation of a fault
number and a relative time stamp for protection related Class 1 events. Despite the
default ASDU type settings it is possible for the user to configure either ASDU
type 1 or 2 separately for each private Class 1 data.
Different Class 2 measurand value sets are selectable. All the standardized ASDU
3 (Meas I) and ASDU 9 (Meas II) sets can be selected. Additionally some IED-
dependent private ASDU 9 frames are also provided. It is also possible for the user
to freely define an own (private) Class 2 measurand set.
IEC 60870-5-103 disturbance files are supported. The RE_615 IEC 60870-5-103
communication stack adapter contains a conversion functionality between the
IED's native disturbance recorder files and the IEC 60870-5-103-specific
disturbance recorder data and settings definitions.
3.2
Communication link
The IEC 60870-5-103 protocol can only operate on a serial communication link.
The standard defines serial data characteristics.
