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:

• Understand the core concepts of power system analysis.
• Apply Power Factory software to model, simulate, and analyze power systems.
• Perform power flow, short-circuit, protection coordination, and arc flash analyses.
• Design protection systems and optimize power system operation.
• Analyze power quality and harmonic distortion in power systems.
• Gained hands-on experience in system-level simulations using Power Factory.

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 equivalent practical work experience in electrical
power systems. i.e.
• New Power Factory users and power engineers who wish to increase their skills using
Power Factory,
• 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 are used to
illustrate particular conditions.

In general, the 70/30 rule is followed (70% of the course period is
dedicated to hands-on Power Factory software and 30% for lecturing technical backgrounds).

Power The factory to be installed on PCs/laptops sufficient for the participants (Maximum 5 participants).

Higher than 5, Instructor and co-instructor are required for this type of course.
