Abstract
It has been shown that fast valving of steam turbines could improve power system stability. Based on Lyapunov stability theory, a new approach for nonlinear control system design is presented in the paper which mainly concentrates on developing a fast valving control scheme for multimachine power systems. The control law obtained is fully based on local feedback, and independent from the parameters of the network of the power systems. This makes online implementation easy. The simulation results of a 3-machine system show that the control law can improve the generator stability limit significantly
