Course Description |
|
This course is designed to provide a comprehensive coverage on the electric power distribution systems. It also provides a strong foundation for distribution system designers, planners and operators a basis for arriving at cost-effective solutions and strategies. It will enable an engineer or a practicing individual in a utility or an industrial environment to design, plan and operate a system. The course is ideal for those who have a basic understanding of power systems and need a practical training in this field. The course can also be taken by engineers who did not specialize in power systems. The course material is also designed to serve as a useful reference in day-to-day functions. It also allows gaining self-paced, in-depth knowledge with the aid of practical examples. The topics covered include latest developments occurring in the industry.
The course covers related issues on basic concepts, equipment models, performance analysis methods and tools, planning, automation, protection, reliability, power quality and economic analysis. Several practical examples and cases are presented, studied and analyzed in this course.
Course Outline:
