GAS TURBINE CONTROL
Gas turbines are used to generate energy for the power network or industrial processes. In either case, high availability and efficiency is critical. Power plants can be fined in case of non-deliveries, and industrial plants can suffer from huge collateral damages due to a failing turbine.
A change in fuel gas quality can result in a stage down (a safety mode with less efficiency) or the complete shutdown of a turbine. Rapid fluctuations in fuel gas composition become more common and require attention to guarantee on-spec performance of the turbine.
By controlling the incoming (modified) Wobbe Index or Heating value, maintenance, downtime and emissions are reduced and efficiency is improved.
