Weddell Power Station Controls Upgrade

PROJECT TITLE:
Weddell Power Station Control Integration with Channel Island Power Station (NT)

CLIENT:
Power and Water Corporation

Background:
Weddell Power Station (WPS) is owned and operated by the Power and Water Corporation (PWC) in the Northern Territory, and comprises two (2) General Electric (GE) LM6000PD SPRINT, aero-derivative type, gas turbine generator (GTG) units and associated supporting infrastructure, with a total nominal generating capacity of approximately 84MW.  The current WPS has a standalone control system. PWC intends to increase the electrical generating capacity (‘augmentation’) of the existing WPS by installing a third OCGT.

Project:
Provecta has been engaged (after an open Tender process) to integrate the existing Weddell Power Station (WPS) Unit 1 and 2 Control Systems and the proposed new Unit 3 Control System into Power and Water Corporation’s existing Yokogawa CS3000 system at Channel Island Power Station (CIPS). The existing WPS facility comprises 2 x GE gas turbine generators and associated supporting infrastructure, and a standalone control system comprising various PLC’s and HMI’s. It is the intention of this project to provide a common control system platform across WPS and CIPS to provide a uniformity of control interface for operating staff. The project will involve the design and installation of up to 4 new CS3000 controllers (FCS’s), 2 new operator stations (HIS’s), a new engineering workstation (EWS), expansion of the ExaQuantum historical data server, and installation of an appropriate communications network to facilitate remote operation of the plant.
