Abstract
The invention concerns a method for coupling to the grid a hydraulic unit having a synchronous generator, a runner, and wicket gates. The method includes a step of increasing the flow of water into the runner from a time tto a time tso that the rotation frequency of the rotor of the synchronous generator is, at time tequal to the frequency of the grid, and closing the circuit breaker at time t. A sub-interval from a time tto time tis defined, with t<=t<t<=t, wherein a sub-step is executed to apply an adjustment torque to the shaft line via a first actuator that controls the flow of water into the runner and a second actuator coupled to a stator of the synchronous generator.
