A Multi-path Model for Disturbance Propagation in Electrical Power Networks

—This paper deals with the nature of propagation of disturbance spectrum through the power lines of an electric power system. A multi-path propagation model is proposed based on the reflection and refraction theory of wave propagation. The developed model captures the spatio-temporal aspect of disturbance propagation and is validated for a wide band of frequency. The proof of concept for the developed model is shown on a 2 -bus system with a disturbance at a point between the buses. Results are validated in time domain with electromagnetic transient simulation programming.
