The object of study is the transients in electrical networks containing components of the motor load. The subject of the study is to simulate the transients in electrical networks of arbitrary configuration. Aim is to develop mathematical models of electrical systems, including components of the motor load, reproduce electromagnetic and electromechanical components of transients in the systems of any configuration and at emergency control actions. To achieve the objective of the following tasks: - the definition of parameters of elements of electrical systems in the phase coordinates, the creation of a data bank; - Development of the elements of electrical systems of mathematical models that reflect the characteristics of their design; - Develop a method for the formation of differential equations of transients for a system consisting of three-phase static and rotating components, inductive and capacitive coupling with constant and variable parameters. - Development of a method for solving systems of differential equations of transients. Research methods are based on the fundamentals of the theory of electrical circuits, theory of electrical machines, electromagnetic field theory, as well as on the methods of mathematical modeling and numerical solution of nonlinear systems of algebraic and differential equations. Model of electromagnetic transients in electric network obtained using the method of phase coordinates. Scientific novelty of the results. Further developed the mathematical model of electromagnetic and electromechanical transients in electrical networks with motor load in phase coordinates, formalized procedures for setting up and solving differential equations for the three-phase circuits, providing the opportunity to study in electrical networks of arbitrary configuration on a single algorithmic basis. The results of research put into practice the operation and design of pumped-storage power plants in various modes of operation of electric network.5481
