The possibilities of modeling the operating modes of electrical networks in the MATLAB Simulink software package are considered and methods for solving the main problems when creating models in MATLAB Simulink are proposed.
Modeling is an important part of the study of the operating modes of electrical networks, it allows you to analyze in advance different options when developing a scheme and choosing equipment for an electrical network.
The main objective of this work is the development of models of overhead lines, cable lines and transformers with the functions of choosing a voltage class, brand of the corresponding equipment and other functions (connection diagrams for transformer windings, type of cable laying, etc.).
PowerFactory, PSS®E, and MATLAB Simulink are among the existing software packages for modeling electrical networks. These software packages allow you to model and calculate electrical systems of various sizes and degrees of complexity.
MATLAB Simulink provides many possibilities for simulation, but since this software package is not specialized for modeling electrical networks, but is created for a wider range of tasks, some functions that could simplify the creation of electrical network models are missing. To reduce the time spent on creating models of electrical networks, enter data into the model in MATLAB Simulink and reduce the size of the models, the corresponding blocks of transformers, cable and overhead power lines 0.4-150 kV were created.
The results obtained are presented within the framework of a joint technical meeting of leading specialists of operating enterprises, the customer and the staff of the Department of Power Supply named after.
