Linear Optimal Control of Transient Stability for Single Generator Infinite System

The predicted value of generator power angle is acquired by predicting transient stability based on real-time parameters.Then the optimal control theory is introduced to ensure the transient stability on the condition that the predicted value of power angle is no larger than the pre-set threshold value.Correspondingly,the adjusted amount for optimal input mechanical power of generators is obtained.Thereby,the power system control based on differential equation is transformed into the optimal control based on generator optimal input mechanical power,with a view to achieving the optimal control of transient stability.
