Hymtek Controls has expertise in tuning hydropower controllers. We have instruments and knowledge required to conduct a survey and tuning of control loops so that the unit complies with current requirements and standards. We measure the dynamic response, adjust the control parameters and documents controller settings all with the unit in operation, we do this by using step response and frequency response measurements. When measuring the turbine controller loop the waterway is also included. Thus, the controller / waterway interaction is verified and the stability is documented properly. Hymatek Controls have all the necessary expertise and computational tools to perform complete control analysis of turbine and waterway.
