Abbreviated as 8LI1NAG-ORMOC, 8LI1NAG-ORMOC HVDC [1] (with "HVDC" at end) and known as Ormoc-Naga HVDC transmission line.
History edit
The feasibility study of the transmission project was conducted by the Japan International Cooperation Agency in 1981.[2] The project financing was approved by World Bank in June 1994, co-financed also by the Japan Export-Import Bank.[3] The HVDC Leyte–Luzon went in service on August 10, 1998.[4][5] It is operated by the privately owned National Grid Corporation of the Philippines (NGCP) since January 15, 2009, and previously by government-owned companies National Transmission Corporation (TransCo) and National Power Corporation (NAPOCOR). It was owned previously by NAPOCOR from August 10, 1998, to March 1, 2003, and is owned currently by TransCo since March 1, 2003.
Technical description edit
The transmission line is an triple-bundle power line and bipolar HVDC.
Capacity of the Leyte-Luzon is a 440 MW.[4][5][6][7] It is implemented as monopolar line for a voltage of 350 kV,[6] feeding the power grid in the Manila region. In addition to overall connection of grids, HVDC was chosen to enable supply of bulk geothermal power, and to stabilize the alternating current network in Manila region.[4][7] The interconnector was manufactured by the ABB Group in cooperation with Marubeni Corporation.[7]
The length of submarine cable is 21 kilometers (13 mi) and the total length of overhead lines is 430 kilometers (270 mi).[4][5][7]
The crossing of San Juanico Strait is realized as overhead crossing with a tower on an island in the strait.
By time in construction of the 1st tower ((8LI1NAG-ORMOC HVDC)0001) was erected and it is now commonly the first HVDC tower in the Philippines.
Route edit
The HVDC Leyte–Luzon begins at Ormoc converter station (Leyte) and ends at Naga converter station (Camarines Sur).[5] It consists three sections:
- Leyte-Samar overhead line
- submarine cables across San Bernardino Strait between Cabacungan (Allen, Samar) and Santa Magdalena (Sorsogon, Luzon)
- overhead line at Luzon
The grounding electrodes are situated at Albuera at 10°54′01″N 124°42′24″E / 10.90028°N 124.70667°E and near Calabanga at 13°43′59″N 123°14′29″E / 13.73306°N 123.24139°E . They are connected with the converter stations by 25 respectively 15-kilometre-long overhead lines. These lines are 69kV DC.
