Abstract
The method of synthesis of equivalent circuits turbogenerators was further developed considering various mutual inductive coupling between excitation and damper winding paths through structural detail by providing the rotor winding and representing massive elements of the rotor with arbitrary number of circuits. To do this during experiments sudden three-phase short-circuit current change should be recorded in the coil excitation. According to a series o f experiments with sudden three-phase short circuit at different voltage in the previous regime we obtained frequency characteristics of conductivity of the stator windings and their corresponding parameters of equivalent circuits for different levels of s aturation ways of magnetic flux scattering for three industrial turbine generators TBB of various capacities: 160, 320 and 500 MW.
