Woodward EGCP-2 - Synchroscope; Figure 3-25. Typical Circuit Using Permissive Function and Run for Auto;Manual Synchronizing

Manual 26086 EGCP-2 Engine Generator Control Package
Woodward 45
High Oil Pressure (numeric)
• Uses Engine mounted pressure sensor.
• Active when generator is stable.
• Display is selectable for PSI (American) or Bar (Metric).
Low Oil Pressure
• Used to sense failure of lube oil system.
• Active when generator is stable.
Synchroscope
Synchronizer Mode
Permissive
• Acts as a synch check device.
• EGCP-2 will not issue speed or voltage bias commands, but if
synchronization conditions are within spec (phase and voltage), control will
issue a breaker close command.
Check
• Used for checking synchronizer prior to commissioning.
• EGCP-2 control actively synchronizes generator by issuing speed and
voltage bias commands, but does not issue breaker closure command.
Run
• Normal operating mode.
• Actively synchronizes and issues breaker closure command.
• EGCP-2 control MUST be in RUN to operate as a dead bus closing device.
• In multiple unit systems EGCP-2 control MUST have AUTO input active to
enable breaker control.

Synchronizing
Synchronizer Gain
• Sets Gain of Synchronizer speed bias output.
Synchronizer Stability
• Sets Stability of Synchronizer speed bias output.
• Both Gain and Stability are used to tune the synchronizer dynamic
response.
