Transient load rejection data obtained from and applied to Kaplan turbines are presented. The dynamic response of the system was investigated and stabilized after blade servopressure analyses. The interrelationship between gate position, blade position, blade servopressure, draft-tube pressure, and speed is shown for Kaplan turbines and propeller turbines for different types of load rejections.
