Competition of self-organized rotating helical autowaves is computationally studied in a nonequilibrium dissipative system possessing the excitability and the two-channel diffusion of excitations. This system consists of three-level active centers interacting locally properties of which are close to the properties of active centers in a phaser (a microwave phonon laser). Dynamical stabilization and coexistence of rotating helical autowaves with different topological charges have been observed under conditions of their weak competition. A self-induced sign reversal phenomenon of a topological charge has been revealed in the case of strongly competing rotating helical autowaves; the mechanism of this nonlinear phenomenon is found. Prospects of investigations of rotating helical autowaves in nonequilibrium dissipative systems with excitable three-level active canters are discussed.
