4.2) Reasons and disadvantages of low power factor.
4.3) Methods for improvement of power factor using capacitor banks, Static VAR Compensator (SVC).
5.) Revenue and Energy loss
Technical losses and Commercial losses, Input energy calculation, Sales calculation, Billing efficiency, Collection efficiency, Total energy billed (KWH), Percent aggregated technical and commercial losses.
Note: Students should visit power generations plants, sub-stations etc.
LEARNING OUTCOMES
After studying Transmission And Distribution of Electrical Power subject, students will able to:
- Select suitable supporting structure, insulators, conductors and other accessories for transmission lines and distribution lines
- Prepare layout plan for HT and LT lines/distribution system
- Prepare estimate for HT and LT (OH and underground cables) lines
- Operate and maintain indoor and outdoor substations
- Use various methods for improvement of power factor
- Assess the revenue and energy loss in power distribution
INSTRUCTIONAL STRATEGY
Since this is a descriptive and practice oriented subject, it is suggested that visits to different types of power generating stations and substations including grid stations be arranged and various equipment, accessories and components explained to the students before the actual class room teaching and make them familiar with the equipment and accessories installed over there. There should be at least 3 visit during the semester. The students may asked to prepare notes while on visit and submit the report and give seminar. In addition, viva-voce be conducted to evaluate the knowledge gained the field visit.
MEANS OF ASSESSMENT
- Assignments and quiz/class tests, mid-term and end-term written tests, model/prototype making.
- Actual laboratory and practical work, model/prototype making, assembly and disassembly exercises and viva-voce.
