Abstract

Nonlinear motion of hydro turbine’s governing system (HGS) will lead to unstability of the power units. In order to solve the problem, we study the stability control of HGS. Firstly, we establish a predictive model of HGS via the fuzzy linearization theory. Secondly, we design the fuzzy predictive controller for HGS. Finally, we use numerical simulations to verify the effectiveness of the proposed method. Results show that the method is effective with advantages such as small over-regulation amount and short transitive time, which is in favor of the stability of HGS. Finally, it can be referenced for stability governing of hydropower system in other projects.
