Coal Plant PLC Upgrade
Macquarie Generation – Liddell Power Station
PROVECTA successfully tendered for and won the contract to upgrade the Stacking and Reclaiming controls for the Liddell Power Station Coal Plant. This project involved replacing the existing relay based controls for the Stacker with Modicon PLC’s, provision of a radio telemetry link between the main coal plant PLC’s and the Stackers and Reclaimers, and the implementation of a highly accurate resolver system to prevent skewing of the Reclaimer. Planelec Services were engaged by PROVECTA as our installation sub-contractor, with all design, drafting, commissioning, training and documentation provided by PROVECTA.
