A supplementary discrete control strategy for generator resynchronization in multima-chine systems is presented in this paper. The supplementary discrete control schemes of the exitation, the fast valving and the brake resistance are also suggested. The digital simulations and the extensive study in a scaled machine-system have been carried out. The results of the studies show that the discrete control schemes are able to ensure a fast and reliable resynchronization of the generator in case of its losing synchronism.
