Power and Water Corporation is responsible for electricity transmission and distribution and provides water and sewerage services across the Northern Territory of Australia, an area of more than 1.3 million square kilometres.

PSC has recently assisted Power and Water Corporation with two distribution substation projects, a new 66/22kV zone substation at Strangways and a project to build an indoor 22kV substation to replace outdoor 22kV switchgear at the Tennant Creek substation.

PSC staff provided major input on the secondary systems associated with these projects.  The secondary systems involved the installation, configuration, integration and commissioning of: IED’s (Management Relays), RTU’s (Remote Terminal Units), communications and a SCADA/EMS (Energy Management System).  These items needed to be seamlessly integrated to effectively provide the required control and protection of the primary plant, and therefore the reliable supply of electricity.

Specific aspects of the projects performed by PSC included:

  • Project management and coordination
  • Architectural and design review
  • Network communication design
  • RTU and HMI configuration
  • SCADA/EMS modelling
  • Field commissioning
  • Point to point testing
  • Technical documentation
  • Support and training

Through detailed planning, coordination and implementation, both substation projects were completed successfully.  This included the cutover process for the system operators when the new equipment was integrated into the EMS/SCADA system.

PSC is pleased to have contributed to these two successful projects for Power and Water Corporation and looks forward to providing additional services to support their electricity network.
