Linear Optimal Control for Transient Stability of Single Machine Infinite Bus System

Based on real-time parameter,transient stability is predicted and the predicted value of generator power angle is obtained.Under the conditions that predicted value of power angle is not greater than the pre-set threshold value,the optimal control theory is introduced;under the condition that the system is transiently stable,the adjusted amount for optimal input mechanical power of generators is obtained;the power system control based on differential equation is transformed into the optimal control problem of the generator input mechanical power,with a view to achieving the optimal control of transient stability.
