Abstract:Due to the existence of hydraulic coupling in the single penstock multi-machine system, the stability time of the unit is prolonged when power disturbance occurs, which is not conducive to the stability of the power system. Based on the synergy theory, this paper builds a nonlinear model of a hydro generator unit with the single penstock two-machine system, adds the synergy factors of the governing system and the excitation system, describes the characteristics of the controlled system, and derives the control… Show more
