Upgrade Solution to meet Guidelines
COMPONENTS
- 2x HEINZMANN Si-TEC Xtend CGC-T
- 1x HEINZMANN Si-TEC Xtend GSM
EGAT (Electricity Grid Authority of Thailand) imposes strict conditions for the quality of power exported to National Grid 115 kV network.
The challenge
The existing turbine control systems at Mitr Phol’s Dan Chang Bio-Energy plant were unable to meet these strict guidelines set out by EGAT. So approached HEINZMANN Australia for an upgrade solution.
The solution
With the assistance of SWTS & MARC, HEINZMANN Australia was able to provide Mitr Phol with a comprehensive steam turbine control upgrade solution. The proposed system included 2x Si-TEC Xtend CGC-T turbine control systems and 1x GSM Master control for grid export power control, to be rolled out over two separate phases.
By the end of June 2017 the full control system upgrade was commissioned successfully, addressing several unique application specific requirements:
- Improved quality of export power up to 25 MW to satisfy EGAT requirements
- Automatic import power control during 32 MW T/G trip condition
- Reduced complexity of system operation, providing consistency and ease of operation
