What is AutoTune?

AutoTune DLE consists of a stand-alone smart solution box that connects to the control system of an LM gas turbine. It is an automated engine efficiency optimizer for LM2500 & LM6000 DLE in part load operation.

AutoTune DLE provides real-time empirical combustion-based engine efficiency optimization.

Specifications

  • A 19” stand-alone box (Containing the 2nd generation AutoTune platform including a combustion dynamics measuring system and digital processing capabilities)
  • Hardwired connections with the controls cabinet and the vibration panel
  • Modbus connection between the controls cabinet and the AutoTune DLE box
  • Back-up / fall back in the controls logic programming
Requirement

A continuous emission monitoring system (CEMS) to provide real-time emission data to the AutoTune DLE box.

What does AutoTune do?

AutoTune DLE automatically optimizes gas turbine combustion by continuously and carefully balancing: Ambient Conditions, Fuel gas, Bleed air, Combustion Dynamics, and Emissions in a closed loop; to achieve optimum combustion efficiency during the part load operation.

AutoTune DLE – Realizing higher efficiency in part load operation

  • Stretches the AB window when staging up from AB to ABC mode (run longer with 0% bleed in AB mode).
  • For staging down from ABC to AB mode avoids high-bleed operation in ABC.
  • In ABC mode reduces compressor bleed as much as possible.

What does AutoTune mean for LM operators?

  • Improving engine efficiency
  • Reducing fuel gas costs
  • Controlling NOx and CO emissions
  • Reducing CO2 emissions
  • Enabling the use of renewable fuels
  • Enabling combustor mode ABC at lower loads
  • Avoiding high combustor acoustics
  • Eliminating seasonal DLE mapping
