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
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.

Powercorp was formed in 1988 in Darwin, Australia, to automate the wide variety of diesel generator power stations in Northern Australia for the Power and Water Authority.
This program encompassed some 80 communities and work has extended throughout Australia and internationally.
With the success of the automation program came the need to integrate renewable energy for fuel saving.
This work and the demand side management capability of the control system led to advanced wind diesel systems in Western Australia for Western Power Corporation.
With the winning of a Showcase grant from the Federal Government Powercorp pioneered high penetration wind diesel systems during the late 90’s.
Powercorp developed expertise in inverter technology with specialization in high speed bi- directional control to solve the grid instability problem.
With these solutions now a commercial reality Powercorp stands as the most advanced high penetration renewable energy company in the world.
This work is expanding to encompass mine sites and industrial complexes.
The company is largely research engineering based with strong capability in electrical network stabilisation and generation plant control.
It stands ready to serve any customer with grid instability problems or requiring high penetration renewable energy generation.
