Velimir Lackovic, MScEE
Course Outline
Reliability is most often expressed as the frequency of interruptions and expected number of hours of interruptions during one year of system operation. A reliability index is the probability that a device will function without failure over a specified time period. This probability is determined by equipment maintenance requirements and failure rates. Using probability and statistical analyses, the reliability of a power system can be studied in depth with digital computer programs.
This course includes
a multiple choice quiz at the end,
Learning Objective
At the conclusion of this course, the student will:
- Definitions of the most important electrical system reliability indexes;
- Key electrical system reliability definitions;
- Data needed for system reliability evaluations;
- Variables affecting reliability indices;
- Method for improving overall electrical system reliability;
- System automated actions for improving reliability;
- Electrical system reliability evaluation methods; and
- Service restoration principles.
Intended Audience
This course is intended for electrical engineers.
Benefit to Attendees
Attendee of this course will be able to determine reliability of the electrical system, calculate critical indexes and propose suitable mitigation measures that will increase overall system reliability.
Course Introduction
Power system design involves consideration of service reliability requirements of loads to be supplied as well as reliability of service provided by any electrical system. System reliability evaluation methods based on probability theory allow the reliability of a proposed system to be numerically assessed. These computational methods permit consistent, defensible, and unbiased evaluation of system reliability that are not otherwise defensible, and that are not otherwise possible.
