We accomplish modernization on turbine generator units such as:

  • Replacing existing analog turbine control systems with fully digital control systems.
  • Upgrading mechanical-hydraulic controls to fully digital control systems.
  • Modernizaton of any type of excitation system to a “state of the art” digital control system.
  • Conversion of exciter machine from brush-commutator to brushless exciter
  • Improvements of control oil system

Excitation system commissioning

A complex excitation system built in 1983 with various protection and monitoring circuits had to be replaced with a new custom excitation system. Our customer’s priority was a minimized downtime (temporary connection saved downtime to remove the old AVR)
