Application (cont’d)
Protection functions
All important protection functions required
for the protection of generators, motors and
unit transformers are included. The system
can therefore replace several relays of a con-
ventional protection scheme. The following
table gives a survey of the most significant
protection functions of REG316*4.
The desired protection functions to suit the
particular application can simply be selected
from a comprehensive library using the per-
sonal computer. No knowledge of program-
ming whatsoever is required.
All setting ranges are extremely wide to make
the protection functions suitable for a multi-
tude of applications. The following main pa-
rameters can be set, among others:
• input channel or channels
• pick-up setting
• time delay
• definition of the operating characteristics
• tripping logic
• control signal logic
Setting a corresponding parameter enables
the protection functions to be ‘connected’ to
particular input channels. Digital input and
output signals can also be connected together
logically:
• The tripping outputs of each protection
function can be allocated to channels of the
tripping auxiliary relay assembly in a man-
ner corresponding to a matrix.
• The pick-up and tripping signals can be al-
located to the channels of the signalling
auxiliary relay assembly.
• Provision is made for blocking each pro-
tection function with a digital signal (e. g.
digital inputs or the tripping signal of an-
other protection function).
• External signals applied to the digital in-
puts can be processed in any desired fash-
ion.
• Digital signals can be combined to per-
form logical functions, e.g. external en-
abling or blocking signals with the output
signals of an internal protection function
and then used to block one of the other
protection functions.
Design
The REG316*4 belongs to the generation of
fully numerical generator protection termi-
nals, i.e. analogue to digital conversion of the
input variables takes place immediately after
the input transformers and all further process-
ing of the resulting numerical signals is per-
formed by microprocessors and controlled by
programs.
Standard interfaces enable REG316*4 to
communicate with other control systems.
Provision is thus made for the exchange of
data such as reactionless reporting of binary
states, events, measurements and protection
parameters or the activation of a different set
of settings by higher level control systems.
Because of its compact design, the very few
hardware units it needs, its modular software
and the integrated continuous self-diagnosis
and supervision functions, REG316*4 ideally
fulfils the user’s expectations of a modern
protection terminal at a cost-effective price.
