QUEENSLAND HEALTH, RBH HERSTON - RBH TI MASE UPGRADE & UQ CCR
MPA was asked to convert the client’s existing TI505 series CPU to Redundant (Hot-Standby) S7-414H CPUs. The project involved the design and construction of redundant CPU cubicles, and the reprogramming of TI PLC code into new Siemens S7 format using structured functions.
This project also involved the design, programming and commissioning of the circuit breaker load-shedding controls and interface with the diesel backup generator.
MPA also supplied the emergency power control system for the University of Qld’s Centre for Clinical Research, also located with the RBH complex.
The system controls the site-wide load shed controls in the event of a loss of power to the site. Each building has its own set of switchboards with essential and non-essential supply distribution and its own PLC controlling these circuit breakers.
The Master PLC now controls the operation of the slave PLCs as well as the High Voltage distribution for the connection/disconnection of three HV Generator Sets with a combined generating capacity of 7 MW.
This integrated approach allows the hospital to precisely tailor the load shed of individual building supply feeds based on very specific load conditions. Detailed reporting and analysis of faults/power usage are also now possible.
PLC
Siemens S7-200, S7-300 and S7-400 PLCs with Citect SCADA v5.41 and Step 7 Programming software.
PROJECT COST $310,000
