description: The purpose of the work: to consider the problems of operation of generator switches as part of powerful energy complexes, in particular, the problems of large aperiodic components of short-circuit currents and long delays of zero current. Perform an analysis. Based on the analysis, develop a replacement scheme for the power plant, which should demonstrate the mentioned problems. Give a numerical estimate of this phenomenon. Methods: to model the substitution scheme, the MatlabSimulink software package is used. Main results: a replacement circuit for a power plant was proposed and developed to simulate the disconnection of short-circuit recharge currents from a synchronous generator. Short-circuit current waveforms describing the problem of a large aperiodic component and zero-current delay are obtained. The theoretical prerequisites for the occurrence of this phenomenon, concerning the operating conditions of the generator immediately before the short circuit and the parameters of the external power system, are considered. This effect can occur when the synchronous generator operates in the reactive power compensator mode.
