An Emerson Process Management product story
Edited by the Engineeringtalk editorial team Sep 10, 2008

Emerson Process Management has announced it has received a contract to replace ageing controls for two 300-MW, combined-cycle blocks at the Bang Pakong Power Plant in Thailand.

Under the contract, awarded by the Electricity Generating Authority of Thailand, Emerson will replace outdated Toshiba controls on blocks 3 and 4 with its Ovation expert control system.

The Ovation system will monitor and control the heat recovery steam generator, steam turbine and balance of plant processes.

It will also interface to the GE Speedtronic Mark VI gas turbine.

In all, the Ovation system will manage approximately 5,600 I/O points per block (11,200 total).

Equipment delivery for Block 3 is expected October 2008 with plant startup slated for January 2009, while equipment delivery for Block 4 will take place July 2009 with plant startup scheduled for October 2009.

Emerson is designing, engineering and supervising this turnkey project.

Bang Pakong, which employs two types of generating facilities - four conventional thermal power units and four combined-cycle blocks - has significantly reduced the country's dependence on imported oil by burning indigenous natural gas.

With an installed capacity of 3,670MW, the plant supplies roughly 15 per cent of Thailand's demand for electricity.
