Power Quality and Reliability
Who should attend?

This training course is designed for utility, plant, or consulting engineers and technicians who work with transmission or distribution systems, or facilities that utilize electrical power. If you are beginning a career or assignment in these areas, this training course will be of value to you. Those responsible for improving system reliability or resolving power quality issues will find this training course especially helpful. Topics will begin at the fundamental level and move to more advanced content as the training course progresses. Prerequisites include a basic understanding of three-phase power systems. This training course is suitable for a wide range of professionals but will greatly benefit:

  • Engineers and technicians new to the power industry
  • Intermediate-level engineers and technicians who seek to improve system reliability
  • Professionals involved with the assessment of power quality
  • Facility engineers and consultants responsible for mitigating power quality issues
  • Engineers tasked with monitoring system performance and reliability
Duration
5 Days
Programme Overview

This training course explores the topic of power quality and its effects on the reliability of the electrical system. Power quality is first precisely defined, because, without a precise definition, measurements of baseline conditions and assessments of improvement are impossible. Then methods of evaluating reliability are investigated. After completing this course, you will have a thorough understanding of how power quality and reliability can be measured, and how changes made to the electrical system will affect these important properties. This training course will feature:

  • Basic terminology and definitions
  • Voltage sags and interruptions
  • Effects of fault clearing on voltage
  • Reliability indices
  • Transient overvoltages and arresters
  • Understanding and mitigating harmonics
  • Analysis of AC power and steady-state voltage regulation
Objectives

By the end of this training course, participants will be able to:

  • Understand common power quality and reliability terms
  • Know how to assess the impact of voltage sags on sensitive electrical equipment
  • Comprehend the influence of fault clearing on voltage stability
  • Calculate and use standardized reliability indices
  • Understand the sources of transient overvoltages and be able to specify arresters
  • Know why harmonics are produced and be able to implement mitigation methods
  • Analyze the components of AC power and understand the relationship with voltage regulation
Methodology
This training course will utilize a variety of proven adult learning techniques to ensure maximum understanding, comprehension, and retention of the information presented. These methods include workshops where attendees practice solving problems (bring a scientific calculator), case studies where concepts covered are applied to real-world situations, and simulations and animations to visually illustrate what would otherwise be abstract concepts in a novel and intuitive manner.
