The method of mathematical modeling of power supply systems with motor load in the transient modes is proposed in the article. This method provides the possibility of submitting the electric network of any configuration. The model is based on equations in the phase coordinates and allows simulating as electromagnetic and electromechanical components of transient modes.
For the formation of equations of transient processes it is used nodal method, for the numerical integration of the equations of transient processes it is applied implicit methods, the formation of the system model is implemented on the basis of discrete models of electric machines.
The mathematical model provides a complete picture of the electrical network, allows simulating all kinds of managing and disturbing external influences to meet the challenges of emergency management, reducing the number of accepted assumptions.
In addition, a possibility of multi-variant calculations for research and study of factors affecting the quantitative characteristics of the transient processes is opened in the case of the presence of computer model.
