No external interface is fitted between the controller and the
AVR and no control over voltage matching or VAr sharing will be made.
Internal Relays – The AVR or motorised potentiometer is controlled by
the DSE8810 modules own internal relays.
NOTE: It will be necessary to configure two of the module
relays to provide the required ‘Voltage raise’ and ‘Voltage Lower’
signals.
Internal Analogue - This external interface is used to provide a DC
voltage output to interface with many AVRs remote voltage adjust or
load sharing controller inputs.
AVR Output Reversed
synchroniser during the period that the set is running on load.
Adjust to Centre Point – Whenever generators are required to run in
parallel, then active load sharing is recommended. However, this may
not be essential when the accuracy of the load sharing is not critical and
is only required for short periods. In this case ‘droop’ AVRs must be
used in conjunction with the ‘synchronising reset option – reset to datum
on load’ feature. This works on the principal that the governed voltage of
each generator for any given load will be the same when at its datum
setting. This approach is generally unsuitable for mains connected
systems but will provide rudimentary load sharing between two or more
generators.
Adjust to Nominal – When on load as a single set (but not in parallel)
the load sharing module will effect changes to the AVR to keep the
system voltage at nominal levels. These levels are user adjustable on
the ‘generator’ tab accessible via Config Suite PC software.
This is used to ensure the nominal voltage of the system is maintained
even if droop is configured.
None – Adjustment will not take place; the speed and voltage will
remain at current levels.
When in parallel with other sets, the DSE load share controller will
automatically keep the system voltage at nominal levels regardless of
the selection of this parameter.
