Electrical Power Systems Modelling and Simulation

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

• Build and validate electrical power system models to support sound engineering analysis and decision‑making
• Analyze power flow and short‑circuit conditions to assess system performance, equipment adequacy, and operational risk
• Evaluate protection coordination to improve system reliability and minimize safety and outage impacts
• Assess arc flash hazards and determine appropriate mitigation measures and PPE requirements
• Apply analysis results to support safer, more efficient, and code‑compliant electrical power systems

Description

As an engineer or technologist responsible for electrical power systems, you are often required to assess system performance under both normal and faulted conditions—while balancing safety, reliability, and compliance requirements. Without rigorous analysis, risks such as equipment damage, unplanned outages, and arc flash hazards can compromise both operations and personnel safety.

This course provides a practical, application‑focused approach to electrical power system analysis using EasyPower software. You will learn how to develop accurate system models and apply structured analysis techniques—including power flow, short‑circuit, protection coordination, and arc flash studies—to evaluate system behaviour and identify potential vulnerabilities.

Through real‑world examples and guided exercises, the course emphasizes how to interpret analysis results and apply them to engineering decisions. By the end of the course, you will be better equipped to design, assess, and optimize electrical power systems that are safe, reliable, and aligned with industry standards and regulatory requirements.
