The Powerlink Energy Load Management System (LMS) consists of a software suite that runs at a Powerlink SCADA Master and controls the total system load by issuing shed or restore commands to the Injection Control plant at the points of injection. Metering pulses are collected from the Points Of Supply (POS) and returned to the LMS where it determines any shed or restores response. Powerlink LMS is a proven system widely used throughout New Zealand by Lines and Energy companies.
