Modeling and Research of Electromechanical Processes in Power Systems

More and more heavy demands are placed on the research accuracy of the transient processes and the stability of the electrical power system (EPS). A method for automatically compiling a mathematical model of EPS is proposed, with the help of which transient electromechanical processes in EPS with an arbitrary distribution network and an arbitrary composition (number of elements) of the system (generators, motors, static loads) can be studied. As a result of the proposed method, the common model of the system consists of an algebraic system of equations whose node voltages are calculated non-iteratively, and separate systems of differential equations for each element of the EPS. An example of the study of transient processes in a specific system is given.
