PROT 407: Transmission Line Protection

Description

PROT 407
Course Information

This is a three-day course.

Course Base Fees: $1,800 USD

PROT 407 provides an in-depth study of the methods used in designing protection systems for high-voltage power transmission lines. The course provides advanced guidelines for relay application and settings for transmission lines, including series-compensated lines. It also reviews time-domain ultra-high-speed line protection principles. The course covers the application and settings of power swing blocking and out-of-step tripping functions.

Audience

Engineers and power system consultants who need a comprehensive understanding of the challenges and solutions for protecting high-voltage power transmission lines should attend this course.

Course Objectives

At the conclusion of this course, students can:

  • Identify the challenges and solutions to transmission line protection problems.
  • Select the appropriate transmission line protection schemes for various applications.
  • Describe current and voltage transformers and their impact on transmission line protection scheme performance.
  • Identify, apply, and calculate settings for transmission line protection schemes, including directional overcurrent, distance, and pilot protection schemes.
  • Describe the various pilot protection schemes for transmission lines.
  • Discuss the advantages of line current differential protection.
  • Describe time-domain ultra-high-speed transmission line protection.
  • Identify the challenges and solutions to series-compensated transmission line protection.
  • Identify and apply power swing blocking and out-of-step tripping.

Student Background and Knowledge

A degree in electrical engineering or equivalent experience is recommended. In addition, we recommend that you complete PROT 401: Protecting Power Systems for Engineers OR have the following:

  • Familiarity with transmission line characteristics.
  • A basic knowledge of protective relay design, symmetrical components, fault analysis, and power system protection.
  • A working knowledge of trigonometry, basic calculus, complex numbers, and phasor concepts.
