Project Work
Completed by the Engineered Systems
and
Manufacturing Groups
East Arm Port SCADA
The new East Arm Port project was a recent large project that utilised the
engineered systems group to design and construct a complete control SCADA
system. The company was contracted by AMEC Engineering to design, supply and
commission all the 415v switchboards and Allen Bradley PLC systems. The system
manages the site by controlling the HV and LV load shedding, standby power
generators, HV and LV transfer switches, lighting control, fire fighting
systems, DC battery banks, scheduled testing, alarming and reporting. The
control system extends throughout the site and utilises a redundant ring fibre
optic network to provide a robust communication system. ISAS developed a high
level interface to the ONAN generators for the standby power and fire services.
This provides full engine and alternator status to the SCADA and reporting
system.
Royal Darwin Hospital BMS
The Royal Darwin Hospital Building Management System (BMS) was installed to
all mechanical services at the site. It provides complete control over the air
handing and chiller plants, security, boilers, pumps, generators, medical gases,
water tanks, steam and condensate, smoke spill control and pressurisation and
monitors the entire fire system for correct operation. The system is based on
Allen Bradley SLC500 and PLC5 controllers networked with fibre and copper
cables. There are approximately 80 PLC’s on the site. Access to any of the PLC’s
is available from ethernet via a ControlLogix 1756 Gateway. Several MMI SCADA
terminals provide system access and programming for operators. The security
system is coupled to the site paging system and provides alarming and control
for the various security doors and duress call systems on the site. The BMS is
programmed to monitor all aspects of the mechanical plant during fire and smoke
modes.
Should any component such as a damper or smoke fan fail to operate correctly for a given fire condition the system will report the fault. The BMS includes 40 off VVVF drives operating a range of equipment.
