Effective Applications of Power Electronic in Power Systems Course
Introduction:
Power Electronics is the technology that links the two major traditional divisions of Electrical engineering, namely, Electric Power and Electronics. It has shown rapid development in recent years, primarily because of the development of semiconductor power devices that can efficiently switch large currents at high voltages and frequencies. Power Electronics techniques are progressively replacing traditional methods of power conversion and control, causing what may be described as a technological revolution in certain power areas such as regulated power supplies and UPS systems, DC and AC motor drives, high voltage DC transmission, etc. The generation of harmonics is considered as the major drawback of power electronics in a world where 'Power Quality' becomes an environmental issue of great concern. Power Quality should, therefore, be addressed.
Course Objectives:
This course is designed to introduce the subject of Power Electronics with a concentration on the:
- Latest advances developments and availability of power semiconductor switches. Proper selection of the type and ratings of the power switch to match the requirements of a certain application will also be investigated.
- Basic merits of Power Electronics converters over the conventional counterparts. Drawbacks of Power Electronics, which are, mainly, the reduction of the input power factor and the generation of considerable load and line harmonics, will also be highlighted.
- Rectification, Chopping, and Inversion processes required for DC and AC power conditioning. This will include power circuits, control topologies, conduction patterns, analysis, and evaluation of the performance parameters of the corresponding controllers.
- Basic guidelines for the design and practical implementation of the different types of controllers. Real design circuitry will be investigated as case studies.
- Evaluation of the harmonic spectra of the load-line waveforms. Reduction or elimination of these harmonics will be investigated.
- Widely used applications of Power Electronics, such as UPS systems and speed control of IM using VVVF control will be introduced.
Who Should Attend?
This course is strongly recommended for Electrical, Electromechanical, and Industrial Engineers and Technicians, who involved in any AC or DC power conditioning system including, but not limited to, power utilities, VVVF speed control of electric motors, and UPS system.
