Eraring deadline for electric actuation
06/12/2013 AUMA Actuators Ltd
Eraring coal fired power station in New South Wales, Australia, located close to Dora Creek and Lake Macquarie, has adopted AUMA electric actuators supplied by Barron GJM. Of the 34 units commissioned to actuate dam discharge valves, 24 were installed within one week to meet urgent actuation requirements.The actuators are adopted at the attemperating dam, a closed loop cooling system for the power station designed to be used in the hotter months of the year. AUMA units support a scheme designed to reduce thermal pollution in Lake Macquarie: the actuation technology is adopted on discharge valves to control flow of cooling water from the dam to the power station. AUMA actuators with controls were supplied to support the scheme's distributed control system.
The scheme's original actuators were damaged and urgent remedial action was required. Due to a strong existing relationship with Eraring Energy, Barron GJM was appointed. A key reason for the adoption of AUMA actuators was the ability to remotely mount the integrated controls, this enables easy access to the local controls, and minimises risk of flood damage if a water leak occurs.
Commissioned in 1982, Eraring Power Plant is owned by Origin Energy. Primary fuel is bituminous coal and maximum power generation capacity is 2,640 MW.
