Design and Analysis of Comprehensive Control System for Hydroturbines

The control system and the characteristics of the turbine governor are reviewed and the analysis is provided, based on which the combined control method is proposed. The simulation results show that this method enables the turbine to maintain stable work in a smooth state, so as to solve the severe turbine vibrations caused by turbine speed instability. These vibrations are apt to cause damage to the equipment and the recovery system does not work properly and so on. Thus the integrated control mode would keep safe and stable operation of the hydraulic turbine, and then energy recovery systems could run efficiently.
