Speed control governors for hydrogenerators utilize a proportional-integral (PI) control with constant gains. Given the nonlinear characteristics of the installations, the result is compromised speed and power transients for step load changes. The PI control is not able to provide a responsive power response while maintaining the desired speed transient. This paper discusses the development of a control strategy that essentially neutralizes the speed dynamics in order to achieve improved power tracking. Employing this technique results in up to a fifty percent reduction in the magnitude of offspeed. The power transient is also more responsive as demonstrated by a twenty percent decrease in the settling time while maintaining acceptable damping and overshoot.
