Automation & Control – Commander Master Controller
The Commander system enables a power station to operate automatically without human intervention, except for monitoring, maintenance of plant and fuel supplies.
The controllers used in the Commander control system are:
- Commander Master Controller
- Generator Controller
- Feeder Controller
The Commander Master Controller automatically controls and monitors all diesel and/or gas generator sets, consumer feeders and fuel tanks in a power station. It provides alarm/event reporting, trending, remote access and external alarm notification.
Depending on system load conditions, the Commander Master Controller starts and stops generators to optimise station fuel efficiency.
The Commander Master Controller maintains optimum loading and spinning reserve on all in-service generator sets.
The Commander Master Controller power management continuously monitors the feeder load and matches the most economical configuration of the generator sets to the demand. By doing so it ensures that the following criteria are met:
- Maintaining the required spinning reserve
- Optimising the loading of generator sets
- Preventing low loading of generator sets
The Commander Master Controller is based on an open controller hardware architecture. Embedded industrial PC hardware is used with distributed I/O to achieve mission critical and highly reliable power station control.
The Commander Master Controller is specifically designed for power station applications and can withstand temperatures between -40ºC and +50ºC.
Communications between the Commander Master Controller, the generator sets and the consumer feeder circuit breakers takes place via fieldbus using the CAN protocol.
The Commander Master Controller enables fuel savings due to better loading of generator sets and fewer operation and maintenance costs due to much improved management of plant assets.
The Commander Master Controller is able to control and monitor:
- Up to 8 Generator Controllers.
- Up to 6 Feeder Controllers.
- An additional 1 Feeder Controller for use as a Local Light and Power Meter.
- Up to 12 Bulk Fuel Storage Tanks.
- Up to 3 Temperature Measurement Inputs.
