EGCP-2 Engine Generator Control Package Manual 26086
50 Woodward
Summary of KVA load switch action:
If the relay 12 output is configured for KVA Load Switch action:
If the three phase sum of the generator KVA is greater than the KVA Switch Low
setpoint, AND less than the KVA Switch High setpoint, the K12 relay output shall
energize. Any other KVA levels relative to the Low and High switch setpoints
shall cause the K12 relay output to de-energize.
Reactive Load Control
VAR/PF Mode
• Disabled
Unit does not PF share, or control PF under any circumstances.
• VAR Control
Unit PF shares in isolated bus load sharing mode.
Unit controls KVAR in Base Load and Process Control Modes.
• PF Control
Unit PF shares in isolated bus load sharing mode.
Unit controls PF in Base Load and Process Control Modes.
VAR/PF Gain
• Controls Gain Response of unit in VAR/PF control mode.
• NOT active in PF sharing mode.
Voltage Ramp Time
• Ramp time from 0 to ±100% voltage bias output.
• Controls response of units in PF sharing modes.
• Controls ramp time of voltage during synchronization.
• Controls ramp time of voltage during manual voltage adjust.
VAR/PF Sharing Gain
• Controls Gain Response of unit in VAR/PF Sharing Mode.
• Not active in VAR/PF Control Mode.
VAR/PF Stability
• Controls Stability Response of unit in VAR/PF control mode.
• NOT active in PF sharing mode.
KVAR Reference
• When KVAR control mode is selected, this references the amount of KVAR
the generator will produce while in Base Load or Process control modes.
• Can be set for generate or absorb levels of KVAR.
• KVAR levels limited by Rated KVAR of unit.
PF Reference
• PF level that will be maintained by the generator while in Base Load or
Process control modes.
• Can be set for leading or lagging power factor.
• Scaled from 0 (unity) to -.5 (.5 leading) to +.5 (.5 lagging).
