# EEE 479 - Power System Reliability

**Section A: General Infromation**

- **Course Title:** Power System Reliability
- **Type of Course:** Optional, Theory
- **Offered to:** EEE
- **Pre-requisite Course(s):** None

## Section B: Course Details

### Course Content (As approved by the Academic Council)

Review of probability concepts. Probability distribution: Binomial, Poisson, and Normal. Reliability concepts: Failure rate, outage, mean time to failure, series and parallel systems and redundancy. Markov process. Probabilistic generation and load models. Reliability indices: Loss of load probability and loss of energy probability. Frequency and duration. Reliability evaluation techniques of single area system. Interconnected system: tie line and evaluation of reliability indices.

### Course Objectives

1. To introduce the fundamentals of power system reliability.
2. To familiarize and understand reliability concepts, reliability modelling of generator, load and power system equipment, reliability indices, and reliability evaluation techniques for such systems.
3. To build the theoretical foundation required for reliability modelling and evaluation of power system.

### Knowledge required

Basic probability and statistics, power systems.
