When the electromagnetic wave transports through apertures into the multi-port microwave chaotic cavities, random coupling model for apertures is derived to predict the statistical characteristics of the coupling voltage. And a complex calculation method, random topology model, which combines random coupling model and electromagnetic topology theory, is elaborated to determine the statistical characteristics...
In this paper, based on the relationship of the losses and rotor speed of generator, the braking time formula with the braking mode of the hydro-generator stator three-phase short-circuit is obtained within considering the stray losses. The breaking times at different braking currents and different input speeds about a 1000 MW hydro-generator are calculated. The results prove that it is feasible and...
