Sažetak
The paper involves an analysis of the impact of some turbogenerator set parameters which con-siderably influence its mechanical behaviour on the calculations of torsional strains. The analysis is carried out for a case of a three-phase short circuit at one of two parallel lines through which a generator is supplied followed by a fault clearing. Maximum torsional torques and critical fault clearing times at which they occur are presented. The mechanical parameters which have the largest influence on the tor-sional strains in the shaft are the stiffness coefficients of the shaft sections and the mechanical time constants (or moments of inertia) of the generator and the turbine rotors. The influence of mechanical damping coefficients is less significant. Maximum torsional torques are also indirectly influen-ced by electrical parameters of the generator, primarily by the subtran-sient and the transient synchronous reac-tance, but their impact is minor. Cal-culated time responses of torsional torques for the combined fault show that inaccurately defined mechanical parameters can lead to wrong conclusions concer-ning maximum values of torsional torques which could occur during a fault.
