Driven Unit – A group of mimics provide access to driven unit control and
monitoring.
Generator Monitoring & Control
The control system provides a mixture of digital and analogue I/O for the generator sequencing /
monitoring and alarm protection. The exact configuration is dependent on the generator
instrumentation and electrical interface, but would typically include:
•
Monitoring of the Shutdown Sequencing and Protection relays,
•
Generator Control Panel Speed Control and synchronizing unit interface,
•
Instrument Fault Monitoring,
•
Message Annunciation,
•
Generator Winding and Bearing Temperature Monitoring and Protection,
•
Generator Cooling Control and Monitoring,
•
Vibration Monitoring of the generator non-driven and drive end seismic probes.
Generator Control Panel (GCP)
Normal control of the generator is achieved from the HMI via a generator control panel (GCP).
Links exist between the GCP and the turbine control system to enable emergency stop and
raise/lower command signals.
The generator control panel also protects and monitors the operation of the generator.
Description
The GCP consists of a cubicle housing various metering, indication, control, protection, and
synchronizing devices and instrumentation as well as the panel switches which enable the
generator functions.
Access into the cubicle can be gained through a front mounted door. Opening the door will
activate a light within the cubicle.
For more specific details of the GCP refer to the ACTEMIUM literature contained in the Vendor
Information Manual.
