Course Code: BEE-001
POWER DISTRIBUTION SECTOR
Maximum Marks: 100
Weightage : 30%
Note : All questions are compulsory and carry equal marks.
Q.1 (a) What are the Key Performance Indices measuring the distribution sector performance?
(b) Mention the key factors driving reforms and change in the power distribution sector in India referring to the current peak and energy shortages.
Q.2 (a) Electricity as a subject appears in the Concurrent list of subjects as per the constitution of India. With reference to IEA 2003 provisions explain how the center-state balance is maintained in developing the sector. What is the remedy in case of conflict?
(b) The power sector reforms were initiated around the early nineties, however the Indian Electricity Act 2003 accelerated the pace of reforms. Do you agree? If yes, justify with reference to the provisions in IEA 2003 and if No, explain why?
Q.3 (a) Discuss the emerging role of Energy Efficiency in the distribution sector in mitigating the demand –supply deficit.
(b) Discuss the relevant provisions of IEA 2003 and National Tariff Policy aimed at rationalizing the tariff in the electricity sector
Q.4 (a) Show with the help of a diagram, how is energy registered correctly in case of electronic meter with neutral removed and load running through the earth.
(b) Giving the internal block diagram of an electronic meter explain the role of watchdog timer.
Q.5 (a) The key to success of distribution reforms is the Business Process Re-engineering. Compare the business processes in the vertically integrated Utility structure and the emerging unbundled structure in the distribution.
(b) Discuss the importance of benchmarking as a tool to push the BPR in a distribution utility.
Q.6 (a) Mention the steps in developing a modern distribution system for a satellite town area. Indicate the planning and design steps involved
(b) Explain the importance of following:
i. Diversity factor ii. Load Factor iii Load Loss factor
Q.7 (a) With the help of a Single Line Diagram indicate the switchgear and equipment used in a typical 33/11 KV sub-station. Mention the annual maintenance practices adopted.
(b) Discuss the variation in dielectric strength variation with altitude. How would the ground clearances or Rod gaps be altered as compared to sea level in a 33/11 KV substation at high altitude.
Q.8 (a) Mention the two parts of R-APDRP? What is the significance of Ring-fencing in loss reduction?
(b) Why was the T&D loss assessment changed to AT&C loss determination in distribution? Hence explain the term AT&C loss.
Q.9 (a) Identify the factors contributing to Technical loss and Commercial loss. Mention the techniques to reduce the Technical losses.
(b) What is meant by Billing efficiency and Collection Efficiency? Give the equation, allowing calculation of AT&C loss from the two efficiency factors.
Q.10 (a) A consumer reverses the CT connections in a three phase four wire metering arrangement. What is the percentage change in energy registered
(b) Distinguish between section 135 and 126 in the context of IEA 2003 dealing with theft/pilferage of energy.
