To gain optimization parameters of hydro turbine PIDgovernor, this paper interprets the approach of optimization designing that uses the Particle Swarm Optimization (PSO) algorithm.
On the basis of modeling, simulation and field test, proposed are the PID parameter setting range of the governor under the large grid operating condition, and the power control mode of the unit.
