Objectives

Programme

The role of electromagnetic transients in the operation and reliability of the electric power systems.

a) Electromagnetic wave propagation

- Ideal single phase – earth return system: Laws governing wave propagation in an ideal single-phase-ground return system. Characteristics and calculation methods of transients resulting from multiple reflexion of electromagnetic waves.

- Exercise: Characteristics of electrical circuits composed by lumped and distributed parameter elements, transients on transmission lines caused by line energization, de-energization and reclosing, protection measures against over-stresses, discharging lines and cables, transients caused by short distance fault current interruption.

- The purpose and construction rules of reference-circuits. Reference circuits of electrical systems of mixed structure with lumped inductance and capacitance.

Understanding physics processes of electromagnetic transients in power systems, being familiar with the origin of transients and their consequences to the operation of electrical energy system. The aim of the course is to help students in understanding transient phenomena appearing at abnormal conditions (e.g. switching on or off, during short-circuit and fault clearing), to be familiar with design practices and protection principles against overvoltages and to get deep understanding about operation of advanced solution methods to reduce the risk of failures. Practical lectures are dedicated to develop simplified equivalent circuits and calculation methods. Students will have an opportunity to learn how to operate modern power system transient simulation software tools and how to create digital models and evaluate results obtained by computer simulation.
