Resistive Model of Synchronous Machines

In case of a complex multi-machine electrical energy system (EES), the describing system equations have a large order if we take into account the system of automatic control of the excitation of generators, the order of the system of equations increases. Therefore, when solving such system equations, specific difficulties appear. However, the increased capabilities of modern computers and software, as well as the representation of differential equations in difference form, which allow replacing the conventional equivalent circuit of a synchronous machine (SM) with resistive (discrete) models, quickly eliminate the problems associated with the order of algebraic and even differential equations. The article discusses the use of a resistive model of a synchronous machine for further use in the study of transients. The advantage of the developed resistive model of a synchronous machine is that it allows one to perform a circuit equivalent of a group of k machines that exempt from logical operations with systems of equations
