EGCP-2 Engine Generator Control Package

Load Surge
A condition in which a step load on the generator ,which
is operating in a mains parallel mode (base load or
process), above a certain amplitude can be used to
trigger a Loss of Mains condition.
Loss of Mains
A condition in which the sensed mains PT input to the
EGCP-2 falls below certain voltage and/or frequency set
points for a given period of time. Load Surge can also be
used to detect a Loss of Mains condition. The EGCP-2
can be configured to trigger a Loss of Mains (LOM)
reaction to these conditions, and provide on site power
generation to supplement the load until such time as the
mains return and are stable.
Mains Parallel
To synchronize and close an operating generator to the
mains. The EGCP-2 can be configured for Mains Parallel
operation.
Master
The Highest Priority unit in an operating automatic
system. The Master Control controls load sharing,
VAR/PF sharing, sequencing, synchronization to the
mains, mains breaker closure/opening, and multiple unit
starting.
Manual
A switch input to the EGCP-2 that puts the control in a
manual operating mode. When in manual, the EGCP-2
does not communicate with other units on the network,
and if in a multiple unit system, will not issue a dead bus
closing command. Being in manual also cancels any
Loss of Mains detection for that particular unit.
Network Address
A unique address assigned to each unit that is operating
in an automatic system. The network address is that
particular units “name” on the network so that it can be
properly identified by other units operating on the same
network.
Network Priority
A unique number assigned to each unit operating in
automatic on the network. Network priority defines the
sequence in which units will be taken on/off load when
operating in an automatic sequencing configuration (load
sharing or process control). Automatic sequencing will
place units on load as required starting at the highest
network priority (lowest numerical value), and adding
units of lower priority (higher numerical value) as the
load on that system increases above certain defined
limits. Automatic sequencing will also remove units from
the load in a reverse order of that used for sequencing
units on load, that is from lowest priority (highest
numerical value) to highest priority (lowest numerical
value).
