Wpływ stałej czasowej obwodu wzbudzenia na przebieg procesu synchronizacji silnika synchronicznego

The work presents calculation results of synchronization process of a one-speed, silent-pole, high power synchronous motor. The calculations were based on the examined circuit model for the high power motor type GAe 1716t. The motor works in fans drives in underground mines. The influence of time constant excitation circuit on stator currents, angle δ, excitation current and voltage, electromagnetic torque and shaft velocity during synchronization process has been investigated. The influence of change value time constant excitation circuit on choice the synchronization moment was examined. Dynamic diagrams of stator currents, excitation current, excitation voltage, angle δ, electromagnetic torque and shaft velocity during synchronization process as results of computer simulation are presented.
