EE6002 Power System Transients (PST) Syllabus

UNIT I INTRODUCTION AND SURVEY

Review and importance of the study of transients – causes for transients. RL circuit transient with sine wave excitation – double frequency transients – basic transforms of the RLC circuit transients. Different types of power system transients – effect of transients on power systems role of the study of transients in system planning.

 UNIT II SWITCHING TRANSIENTS

Over voltages due to switching transients – resistance switching and the equivalent circuit for interrupting the resistor current – load switching and equivalent circuit – waveforms for transient voltage across the load and the switch – normal and abnormal switching transients. Current suppression – current chopping – effective equivalent circuit. Capacitance switching – effect of source regulation – capacitance switching with a restrike, with multiple restrikes. Illustration for multiple restriking transients – ferro resonance.

UNIT III LIGHTNING TRANSIENTS

Review of the theories in the formation of clouds and charge formation – rate of charging of thunderclouds mechanism of lightning discharges and characteristics of lightning strokes – model for lightning stroke – factors contributing to good line design – protection using ground wires – tower footing resistance – Interaction between lightning and power system.

UNIT IV TRAVELING WAVES ON TRANSMISSION LINE COMPUTATION OF TRANSIENTS

Computation of transients – transient response of systems with series and shunt lumped parameters and distributed lines. Traveling wave concept – step response – Bewley’s lattice diagram – standing waves and natural frequencies – reflection and refraction of travelling waves.

UNIT V TRANSIENTS IN INTEGRATED POWER SYSTEM

The short line and kilometric fault – distribution of voltages in a power system – Line dropping and load rejection – voltage transients on closing and reclosing lines – over voltage induced by faults –switching surges on integrated system Qualitative application of EMTP for transient computation.
