Interdisciplinary modelling of transient processes in local electric power systems including long supply lines of distributed parameters

Based on interdisciplinary approaches to modelling that use a modified Hamilton-Ostrogradsky principle, a mathematical model of an electric power system including a supply line of distributed parameters, transformers operating in parallel to both sides of the line, and other parts of the electric power system is proposed. Use of a modified Hamilton-Ostrogradsky principle as an interdisciplinary approach extends the range of variation approaches to dynamic systems analysis of both concentrated and distributed parameters.
