In tandem with the Tamil Nadu Generation and Distribution Corporation (TANGEDCO), the Tamil Nadu Transmission Corporation (TANTRANSCO) has also taken up establishment of transmission network adequate to evacuate the power generated from the proposed new power plants and also to efficiently distribute further down the channel. It is proposed to establish 400KV substations with 2500 ckt km of 400 KV lines, 230 KV substations and 200 numbers of 110 KV substations during Twelfth Five Year Plan. In addition to this for efficient flow of power across the State, TANTRANSCO will lay a backbone network of 400 KV double circuit line with Quad conductors connecting the following substations during the plan period

i.e., Kayathar(New Sub Station (SS))- Karaikudi (existing PGCIL SS) - Pugalur (existing PGCIL SS) – Singarapet (New SS) – Ottiyambakkam (New SS).

Further, to harness the full potential of eco–friendly wind power, an exclusive

corridor for evacuation of wind power is also programmed during the plan period as set

out below:

• Thappagundu (New SS) - Anaikadavu (New SS) -Rasipalayam (New SS) - Salem(765 KV new SS by PGCIL).

• Abhisekapatty(PGCIL SS) –Kanarpatty (Prop. New SS) – Kayathar (New SS) –

Thennampatti (New SS) – Kovilpatty (New 765 KV PGCIL SS).

• Vagarai (New SS) – Singarapet (New SS)

17.  From Reference 1, Find efficiency ,regulation and cost required for  Kayathar(New Sub Station (SS))- Karaikudi (existing PGCIL SS) - Pugalur (existing PGCIL SS) – Singarapet (New SS) – Ottiyambakkam (New SS). (A-9)

18.  From Reference 1, Find efficiency ,regulation and cost required for  Thappagundu (New SS) - Anaikadavu (New SS) -Rasipalayam (New SS) - Salem(765 KV new SS by PGCIL). (B-9)

19.  From Reference 1, Find efficiency ,regulation and cost required for  Abhisekapatty(PGCIL SS) –Kanarpatty (Prop. New SS) – Kayathar (New SS) – Thennampatti (New SS) – Kovilpatty (New 765 KV PGCIL SS). (A-10)

20.  From Reference 1, Find efficiency ,regulation and cost required for  Vagarai (New SS) – Singarapet (New SS) (B-10)

21.   ISSUE 1:  TN was heavily affected by lack of transmission lines to evacuate power from plants in one part of the state to regions that require power. Despite the availability of power, especially from windmills with a capacity of more than 7,000MW, TN lost over 2.1 billion kwh of power last year alone due to lack of transmission infrastructure, it is estimated.

"The commissioning of the transmission lines will help improve the power situation in Chennai as power generated from windmills in the southern part can be transmitted to the rest of the state and to Chennai, which are power starved," said K Venkatachalam, chief adviser of Tamil Nadu Spinning Mills Association, which owns most windmills in the state.

How to resolve the above issue. Do detail analysis ( Efficiency, Regulation and cost)

Explain green energy corridor project in India. (A-11)

22.  Explain Growth in transmission sector in India. Write technical solution (lke strengthening transmission corridor between region)  to reduce power deficits in southern region of India. (B-11)

23.  Explain difference between 3 phase and 6 phase transmission line. Under smart city plan TRANSCO planned to convert all 3 phase HV to 6 Phase HV,  Find efficiency , Regulation. (A-12)

24.  Explain difference between Cable transmission line and Overhead Transmission line. Under smart city plan TRANSCO planned to convert all 3 phase HV to Cables Find efficiency  and cost. (B-12)

25.  Explain Sakthi sugars Power system Structure. Write your suggestion ( transmission point of view)  to improve its performance.

26.  Explain Suzlon Power system Structure. Write your suggestion ( transmission point of view)  to improve its performance.
