Synchronous generators running in parallel at hydro plants are sensitive to electromechanical and hydraulic oscillations. In particular, partial load torque oscillations and active power noise can be caused by turbine vortices. Without artificial damping and suitable filters, these disturbances can result in electric power oscillations. In the case of weak grid connections caused by high impedance, the coupling between the units is stronger than the grid coupling. The influence of low frequency disturbances on the dynamic performance of the overall electromechanical system is discussed here.
