An electric conversion for mechanical-hydraulic governors of water wheel turbines
Technical Report
·
OSTI ID:5141732
A conversion system for upgrading performance of conventional mechanical governors for hydraulic turbines has been developed. The conversion retains the proven long-term stability of the ball head speed reference but replaces the dashpot function with erivative terms from an independent frequency sensor. The result upgrades the governor system from temporary-droop type to a higher order double-derivative type. Installation is simple. All original mechanical apparatus is retained for startup and standby; control can be transferred instantly. The advantages are a higher sensitivity to small system speed deviations and faster, smoother response to system load control.
