  1. EE 215 Electric Energy Systems AnalysisChapter 3: Transmission lines Paul Hines, Ph.D.

  2. What is a Power Grid? M. El-Sharkawi, Electric Energy: An Introduction

  3. Chs. 3. Transmission Lines

  4. Transmission lines • The PI model • Parameters • Type of conductor • Number of conductors/phase • Position of phases • Location of neutral

  5. Skin effect and ACSR

  6. Conductor bundling

  7. Transposition • Coupling between phases and phase-to-ground depends on a variety of factors • To keep things balanced, we need to transpose the phases

  8. Unbalanced transmission lines • “Positive sequence” • Voltage-current relationship (Linear algebra)
