In the 34th Standing Committee, the following system has been agreed for additional inter-connection with ISTS and increased reliability. LILO of one Rasipalayam – Palavady (Singarapet) 400kV D/c line at Salem 2.0 The erection of Thappagundu – Anaikadavu – Rasipalayam 400kV DC line with 400kV substations is on the fast track, which has been approved in the 34th Standing Committee Meeting for the evacuation of wind power projects. 3.0 Now, the land for the Singarapet 400kV SS has been identified near Salem (Dharmapuri) 765kV PGCIL SS i.e., at Palavady., and the work is expected to be taken up shortly. Out of the 2 DC 400kV circuits from Rasipalayam to Palavady (Singarapet). One DC circuit has been already taken up and the other DC circuit is included in the Kfw funding. 4.0 As communicated by PGCIL that Salem 765kV substation is initially to be charged at 400kV level, there are no bays available at Dharmapuri substation for TANTRANSCO now, and at a later stage when the operating voltage is at 765kV level, 400kV bays will get released for termination of TANTRANSCO lines. Now, it is requested that at least one of the Rasipalayam – Palavady 400kV line, the execution of which is on the fast track may be permitted to be made LILO at Dharmapuri. 5.0 The two numbers 400kV Bays meant for ICTs in the Salem 765kV SS may be temporarily permitted to be used for making LILO of the above said line. -sd( K.Viji) Chief Engineer/Planning & R.C (For Director/Transmission Projects) Annex 10.1 Agenda of Reactive Compensation for Various Transmission Schemes approved in previous SCMs Reactive Compensation is proposed on the new transmission lines upon approval of Standing Committee and preliminary survey so that approximate line length is available for Reactive Power Planning Studies for normal operation & for charging of the transmission lines. Accordingly, Reactive Compensation has been proposed for the following transmission Schemes approved in previous Standing Committee Meetings: 1) Wardha – Hyderabad (Maheswaram)765 kV Link: ¾1 no. 240 MVAR, 765 kV Bus Reactors at Nizamabad. ¾1 no. 240 MVAR switchable line reactor at Maheshwaram and Wardha for both circuits of Wardha – Hyderabad (Maheshwaram) 765kV D/c line with anchoring at Nizamabad. ¾1 no. 240 MVAR switchable line reactor at Nizamabad for both circuits of Wardha – Nizamabad 765kV D/c line and Nizamabad – Hyderabad (Maheshwaram) 765kV D/c line 2) Substation works associated with Hyderabad (Maheswaram) 765 kV Substation ¾2 nos. 240 MVAR, 765 kV Bus Reactors at Maheshwaram Pooling Station System Studies were carried out for assessing Reactive Compensation for the above transmission Schemes and the results have been given at Annexure‐I 3) Sub‐station Works associated with System Strengthening in Southern Region for import of power from Eastern Region: ¾ 1 no. 240 MVAR switchable line reactor at Vemagiri Pooling Station and Srikakulam Pooling Station each for both circuits of Srikakulam PP – Vemagiri‐II Pooling Station 765kV D/C line. ¾ 2 nos. 240 MVAR, 765 kV Bus Reactors at Vemagiri Pooling Station. ¾ 1 no. 80 MVAR, 400 kV Bus Reactors at Vemagiri Pooling Station System Studies were carried out for assessing Reactive Compensation for the above transmission Scheme and the results have been given at Annexure‐II 4) Transmission System associated with ISGS Projects in Nagapattinam/Cuddalore Area of Tamilnadu – Part A1 (b) ¾1 no. 63 MVAR line reactor at Nagapattinam Pooling Station and Salem New (Dharmapuri) each for both circuits of Nagapttinam Pooling Station – Salem (New) 765 kV D/c line (initially charged at 400 kV) being implemented under Tariff based Bidding. ¾1 no. 63 MVAR line reactor at Madhugiri end of Salem New (Dharmapuri) – Madhugiri 765 kV S/c line (initially charged at 400 kV) being implemented under Tariff based Bidding. System Studies were carried out for assessing Reactive Compensation for the above transmission Scheme and the results have been given at Annexure‐III. Annexure‐I Studies for Reactive Compensation for Wardha – Hyderabad (Maheswaram) 765 kV Link & Substation works associated with Hyderabad (Maheswaram) 765 kV Substation Studies for provision of Line Reactors Wardha – Nizamabad – Hyderabad 765kV D/c line Line Length: • Wardha – Nizamabad 765kV D/c line – approx 270 Km • Hyderabad – Nizamabad 765kV D/c line – approx 270 Km Following results have been obtained while charging the Wardha – Nizamabad – Hyderabad 765kV D/c lines without line reactors, the relevant outputs are enclosed at Exhibit‐I Charging of Wardha – Nizamabad line from Wardha end without line reactors Source rise Line Rise Total Rise – – – 11 kV 40 kV 51 kV Charging of Hyderabad‐Nizamabad line from Hyderabadend without line reactors Source rise Line Rise Total Rise – – – 55 kV 42 kV 97 kV From the above it may be seen that charging of Wardha – Nizamabad line or charging of Hyderabad – Nizamabad line without line reactors shall lead to very high voltages at the open end and practically not possible to charge the lines under such conditions. Further, the voltage at Nizamabad bus crosses 800 kV thus rendering it impossible to charge either circuit from Nizamabad end. Similarly to control the bus Voltages during off‐peak conditions or while charging of the lines at Wardha, Nizamabad and Hyderabad substations, necessary bus reactors were also identified. Accordingly, necessary line reactors were identified through reactive power planning studies for charging of the lines.
