Introduction

The EGCP-2 is a microprocessor based complete generator load control and engine management package. It will operate with a voltage regulator and various speed controls to automate and protect diesel or gas engine-based generator sets from 400 to 3600 rpm.

Designed for generator sets up to 30,000 kW, the EGCP-2 can be configured to operate stand-alone or utility paralleled. A network of EGCP-2 controls is capable of controlling up to eight un-manned generator sets for backup power, baseload, or peak shaving applications.

Engine Control

• Engine Pre-glow Control 

• 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 SCR 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. 

 • 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 

 • Externally adjustable Base Load or Process Reference Levels with independent ramp rates 

 • kW droop provided for manual load control.

Reactive (kVAR) Control

• VAR sharing on isolated busses based on percentage reactive load (allows different rated machines to proportionally balance kVAR loads). 

• Constant Power Factor or VAR control on units in Base Load or Process control mode. 

• Externally adjustable VAR or PF control reference levels.

Automatic Generator Sequencing

• Automatically starts additional EGCP-2 equipped generators when load exceeds a user specified percentage of the rated load of the operating machines. 

• Provides controlled unloads for engines when the load is low enough that the remaining engines will not exceed a user specified percentage of the rated load. 

• Engine priority sequence can be changed from any unit or from a PC to equalize run-time.

Generator Protective Features

• Over/Under Voltage 

• Over/Under Frequency 

• Reverse Power (Inverse time delay) 

• Reverse VARs • Overcurrent (Inverse time delay) 

• Loss of Mains (Utility) detection 

• Speed/Frequency Mismatch 

• Load Surge 

• kVA Load Switch

Engine Protective Features

• High/Low Coolant Temperature 

• High/Low Oil Pressure 

• Overspeed 

• Start Failure 

• Six user configurable, discrete fault inputs

Communication – PC Interface

• Easy upload and download of unit configuration parameters 

• A PC can control or monitor any unit at a site via RS-422 serial port using Modbus® * or ServLink protocol 

• For complete details see Communication Manual 26181

Hardware

The EGCP-2 is an integrated control package. All control hardware is contained in one compact enclosure.

Figure 2-1 is a physical outline drawing with dimensions of the EGCP-2 for reference during the construction of mounting panels, etc.

To mount the EGCP-2 panel use type M5 x 12mm thread forming screws (Woodward part number 1029 529). Eight mounting screws are shipped with each control.
