Description
The SIGMA Generator Control and Protection System is a range of
integrated modules for protection and control of marine and land
based generators. The modules are marine approved and include all
relevant functions, such as protection of generators, synchronizing
and active/ reactive load sharing and Power Management.
IO/P Module S6000
Input/ Output and Protection Module
The SIGMA S6000 performs all measurements on the
generator side (voltages, currents, frequency), does the
generator protection, includes a non-essential load trip in
two steps and includes three measurement transducers.
S/LS Module S6100
Synchronizing and Load-Sharing Module
This module performs the control functions like synchronizing
and active and reactive load sharing. It performs the
measurements on the busbar side.
S6610 Power Manager Module
Controls the number of generators that are
supplying to the bus. It will issue start and
stop signals to the generators depending
on power requirement. There are 10 inputs
for large consumer requests.
S6500 User Interface Module
This unit is optional, as the S6000/S6100
also can be programmed from a PC.
It is possible to use one or more units
per installation.
