An optimal-variable-aim control strategy of generator resynchronization in multimachine power systems is presented.The strategy is based on optimal-aim controls and characteristics of power systems.When a generator is out of step,tbe control strategy drive system states firstly to an artificial medial equilibrium point and secondly to a desirable equilibrium POint.Using an observation decoupled state space model of multimachine power systems,an excitation and fast valve control scheme of generator resynchronization is derived.Ii is easy to implement the scheme because it needs only local information and can obtaih a close-loop feed control.Digital simulating results show that if a generator is out of step,it can be fastly resynchronized by the optimal-variable-aim control strategy.
