ROYAL BRISBANE HOSPITAL - HIGH VOLTAGE SERVICES NETWORK CONTROL SYSTEMS / Job No: #2660
DESCRIPTION
MPA commissioned, designed and programmed a high voltage services network control system at the Royal Brisbane Hospital, Queensland for John Goss Projects.
This included PLC/SCADA software design and development, functional specifications, all PLC termination drawings, software and hardware commissioning. This system consisted of four new PLC control cubicles for the “Central Bock” to control switchgear in main switchboards, together with the modification of PLC software in the central energy plant including 11kV generator PLC. The PLCs control the high voltage and low voltage circuit breakers, which supply electricity to the entire hospital. The main purpose of the PLC/SCADA controls is to supply and distribute
emergency (generator) power in the event of an ENERGEX supply failure. It is essential this be performed as quickly as possible, while minimising any disturbance to the hospital.
TECHNICAL SPECIFICATIONS
MPA networked five S7300 PLCs via fibre optic LAN to a 545 master PLC for remote control and monitoring of 11kV and 415V switchgear in the new main intake substation of the Royal Brisbane Hospital and the Central Energy Plant. The PLCs control and monitor over 1000 CBs and two 11kV 2.5MVA generators to provide standby power control, controlled load shedding and essential load restoration, co-generation, no break resynchronisation and generator test mode. All devices and switchboards are monitored and controlled via a Citect SCADA system, which is also on the PLC LAN.
PLC
4 x S7 315-2DP, 1 x 545-1104, 4 x OP7, OLMs, 4 x CP340 + Modbus, Citect SCADA modbus interface to RBH BMCS, Profibus DP/ S7 funs, network at 1.5Mbit/s.
PROJECT COST $520,000
