Prerequisites:
• Basic knowledge of electrical circuits and systems.
• Familiarity with power systems (generation, transmission, distribution).
• Prior experience with simulation software is helpful but not required.

By the end of this course, participants will be able to:
1. Understand the core concepts of power system analysis.
2. Apply PowerFactory software to model, simulate, and analyze power systems.
3. Perform power flow, short-circuit, protection coordination, and arc flash analyses.
4. Design protection systems and optimize power system operation.
5. Analyze power quality and harmonic distortion in power systems.

6. Gain hands-on experience in system-level simulations using PowerFactory

This course is intended for anyone who must perform calculations, provide settings or approve the work performed by others. The trainee should be a graduate engineer or have the equivalent practical work experience in electrical power systems. i.e.

• New PowerFactory users and power engineers who wish to increase their skills using PowerFactory,
• Knowledge of power system engineering concepts is highly recommended for those attending this training,
• Consulting Engineers,
• Electrical Engineers,
•  Project Engineers,
• Commissioning & testing Engineers.

The course is designed to maximize delegate benefit from the outset. The goals of each participant are discussed to ensure their needs are fulfilled as far as possible. Questions are encouraged throughout particularly at the daily wrap up sessions. This provides opportunities for participants to discuss specific issues and if possible find appropriate solutions. Case studies are employed to highlight particular points and appropriate video materials used to illustrate particular conditions. In general, 70/30 rule is followed (70% of the course period is dedicated to hands-on PowerFactory software and 30% for lecturing technical backgrounds). PowerFactory to be installed on PCs/laptops sufficient to the participants (Maximum 5 participants). Higher than 5, Instructor and co-instructor are required for this type of courses.
