Asynchronous switching control of dual-machine power systems with the generator tripping

Large disturbances or failures often occur in the actual power system, and emergency control is an effective way to avoid great fluctuation that damage the system stability. For a dual-machine power system, emergency control can be realized by the generator tripping. Consider the time delay of generator tripping, based on the principles of switching control, a new asynchronous switching control model is first built in this paper. Switched dual-machine power system is expressed as a new model in the form of an asynchronous switched system, and the stabilization is carried out for the system to guarantee the asymptotic stability and exponential stability for the system. Simulations on a dual-machine power system show the effectiveness of the new result obtained in this paper.
