Control Overview
Introduction
The EGCP-2 is a microprocessor based complete generator load control and
engine management package. It is designed for use with an automatic voltage
regulator and Woodward speed control to automate and protect diesel or gas
engine based backup generator sets.
Designed for small to medium size generator sets the EGCP-2 can be configured
to operate stand-alone or utility paralleled sets. A network of EGCP-2 controls is
capable of controlling up to eight un-manned generator sets for backup power,
base-load, or peak shaving applications.
Engine Control
• Engine Pre-glow
• Fuel Solenoid Control
• Engine Starter Control (Cranking)
• KVA Controlled Cool-down Timer
• Oil Pressure Monitoring
• Water Temperature Monitoring
• Battery Voltage Monitoring
• Speed Monitoring with Overspeed Protection
• Idle /Rated Relay
Synchronizing
• Digital signal processing to eliminate problems induced in systems with high
harmonic content causing multiple zero crossing of voltage waveforms.
• Adjustable maximum phase window, voltage window, and dwell times—
windows as small as 2° phase error and 0.1% voltage matching
respectively.
• Safe dead bus closing logic internal to the control.
• Multiple shot re-closing with adjustable time delays, auto-resynchronizing,
and synchronizer time-outs all available.
• Manual voltage and speed adjusts for manual synchronizing (Sync-Check
still active during manual parallels).
• Synchronization across generator and mains breakers.
Real (kW) Load Control
• True RMS power calculations for rapid, accurate load control even in the
presence of harmonics.
• Smooth user chosen ramp rates into and out of each mode of operation.
• Isochronous load-sharing of up to 8 units based on percentage loading
(allows different rated machines to proportionally balance kW loads).
• Constant base loading for optimum fuel efficiency with discrete inputs to
change load levels remotely.
• Import/Export control with an external watt transducer.
• Soft Utility Transfer Function
