Advanced Power Transmission Technologies Course
Introduction:
The world's electric power supply systems are interconnected in one way or another and in various regional and in many cases inter-regional and international connections. The reason behind such a complex operation of the power network is to reduce costs of operation and increase the reliability and security of the power supply.
Course Objectives:
- To present fundamental concepts of compensation of transmission networks.
- To discuss the state-of-the-art power electronics equipment available to transmission engineers to improve the operation of the said networks.
- To become familiar with the latest developments in transmission systems
- In addition, the principles learned from this course can be applied to a work environment where known problems of operating the network can be studied and dealt with the equipment discussed and presented in this course.
