Aim

The aim of this course is to introduce and investigate the use of power electronics in power systems, both at transmission and distribution level. In particular, the configuration, design and control strategy for the different devices will be treated during the course. At the end of the course the student should have a proper understanding of the different problems that can be encountered at the different voltage levels in the power systems and how to approach and solve them.


Learning outcomes (after completion of the course the student should be able to)

  1. Describe the technical characteristics and performance of the electric power system with and without power electronics support.
  2. Identify, formulate and analyze complex problems in electric power engineering, such as power system stability, power system bottlenecks and power quality phenomena.
  3. Make choices of solutions for different kind of problems in the power system and motivate them based on relevant criteria.
  4. Identify, select and use different power electronic based solutions for improving both the steady state and the transient performance of the power system.
  5. Carry out electric circuit modeling and analysis using the simulation tool PSCAD/EMTDC.

Content

  • Review of power electronic devices and power electronic converters.
  • Review of power system theory: long and short lines theory, power flow, voltage profile among a transmission line.
  • Need for reactive power compensation. Principle of middle point compensation.
  • Shunt compensation in transmission system: ideal compensation, rotating Var compensation.
  • Shunt-connected FACTS devices: Thyristor Controlled Reactor (TCR), Thyristor Switched Capacitor (TSC), Static Var Compensator (SVC), STATCOM.
  • Series compensation in transmission system: ideal compensation, impact of fixed series capacitors.
  • Series-connected FACTS devices: GTO Thyristor Controlled Series Capacitor (GCSC), Thyristor Controlled switched Capacitor (TCSC), Static Synchronous series Compensator (SSSC).
  • Power transport in transmission systems: AC versus DC.
  • High Voltage Direct Current (HVDC): principle of operation of HVDC classic and HVDC light.
  • Review of power quality problems at distribution level: harmonics, voltage dips.
  • Custom Power Devices for voltage dip mitigation: Static Transfer Switch (STS), Dynamic Voltage Restorer (DVR), D-STATCOM.
