Steam Turbine and Power Management Control Upgrade

COMPONENTS

3x HEINZMANN Si-TEC Xtend CGC-T
8x HEINZMANN Si-TEC Xtend GSM

With the assistance of SWTS & MARC, HEINZMANN Australia was able to provide Baanrai Sugar Industry with a comprehensive steam turbine and power management control upgrade for 2x 27 MW & 1x 20 MW T/Gs.

The challenge
PEA (Provincial Electricity Authority) provides Baanrai with a 22 kV grid connection via PEA grid #1 and #2. The existing governing system installed was a combination of WW 505’s and UG8 governors. The main issues that Baanrai was experiencing was very poor grid export power regulation and significant voltage swings, making it difficult to maintain a parallel grid connection with the 27 MW T/G. In some cases, PEA grid #2 trip also caused tripping of 27 MW T/G. This led to factory shutdowns & significant “downtime”.

The solution
The upgrade of the steam turbine control and the generator management system resulted in improved quality of export power (via GSM), satisfying PEA grid standards and the added feature of grid voltage control (via GSM) maintained a steady 22.0 kV. This also eliminated trips on “over & under voltage”, with no need for OLTC (On-Line Tap Changer) adjustment. The ROI for Baanrai was around 3 months.

Upgrade of ABB Turbine Control

IBW Virginal opted for the HEINZMANN Si-TEC Xtend CGC-T system to not only upgrade but also improve their ABB turbine control. The control strategy requested by IBW was “Automatic Inlet Pressure Control” with the option of operating in “Automatic Base Load kW Control”.

Upgrade of Steam Turbine and Power Management Control

Arcante Blois Incineration Plant processes over 85,000 tons of municipal solid waste annually. The plant processes waste and uses the combustion heat to convert to saturated steam. The steam supply (44 bar) is used for generating electricity, while the process steam (6.4 bar) is used for district heating.
