Royal North Shore Hospital Electrical SCADA

The new $1.125 billion Royal North Shore Hospital and Community Health Services Redevelopment Project consolidates 53 out-dated buildings on the current Royal North Shore Campus into new purpose built facilities that can expand to meet future health care needs.

The focus for PlantWeave Technologies was the design and installation of a Supervisory Control and Data Acquisition (SCADA) System that enabled the standalone monitoring and automatic control of the High Voltage and Low Voltage Switchgear for the new Main Hospital Building. The goal of the SCADA System was to control the switchgear in the event of a Mains Power Outage and ensure that power to all sections of the hospital is maintained.

Key Objectives

The key challenges and concerns for the project were as follows:

  • The SCADA System had to be robust and reliable to ensure that it could operate when needed. The completed system was required to exceed an availability of 99.995% and have no single point of failure.
  • Integration between the Siemens PLC and SCADA System to Schneider Electric High Voltage Switchgear.
  • Integration between the Siemens PLC and SCADA System to the Hospitals Building Management System.
  • Automated switching between the Mains Supply and the onsite Generator System to ensure continuous power to the Hospital.

Plantweave's Solution

PlantWeave’s solution was to install a Siemens redundant PLC and redundant HMI System. This decision ensured that the PLC and HMI Layers would integrate seamlessly and easily with each other to make the job of installing and commissioning the System easier for our commissioning team.

The PLC’s were configured to run in a Master/Slave configuration, whereby the Slave would take control of the automatic switching should a failure be detected with the Master PLC. Similarly, the HMI System was implemented with two HMI Servers which mirrored the Master/Slave arrangement of the PLC Layer.

A dual ring fibre network ensured that there were multiple connection paths between PLC’s, HMI Servers, Remote IO Units, Network Switches and Operator Controlled Touchpanels, to ensure redundancy in the event of hardware failure.

This level of redundancy ensured that the delivered solution met the stringent availability requirements of the client.

The SCADA System was setup in our in house laboratory and rigorously tested by the Client before installation onsite.

Key Outcomes and Benefits

The key outcomes and benefits for the project were as follows:

  • Expertise in Siemens Redundant PLC and SCADA System Installations.
  • Conformance to high system availability and reliability requirements.
  • Integration of Siemens Hardware and Software with Schneider Electric Hardware.
  • Complete testing and verification of the SCADA System by the Client before site deployment.
