Construction implementation of Ninh Hoa 220kV Substation Project (Khanh Hoa) and its connection lines

On December 29, in Khanh Hoa, the Power Transmission Project Management Board (under the National Power Transmission Corporation) organized the construction implementation of the Ninh Hoa 220kV Substation Project (Van Ninh district, Khanh Hoa province) and its connection line. It is expected that the project will be completed in January 2025.

Units determined to complete  project to meet the set progress goals

The project is invested by the National Power Transmission Corporation (EVNNPT) and managed and operated by the Power Transmission Project Management Board (NPTPMB).

The project is scaled to install 1 220/110/22kV - 250MVA transformer. The 220kV side uses a two-busbar system diagram with loop busbars, including 10 bays. During this phase, there is an equipment installation for 6 bays (4 feeder bays, 1 total bay, and 1 breaker bay), using a two-busbar system diagram. Backup 1 loop bay, 1 total bay of 250MVA transformer, and 2 feeder bays.

The 110kV side uses a two-busbar system diagram with a loop busbar, including 15 bays. During this phase, there is an equipment installation to connect 6 bays (4 feeder bays, 1 total bay, 1 breaker bay). Backup 6 feeder bays, 1 total bay of 250MVA transformer, 1 loop bay, and 1 condenser bay.

The 22kV side uses a block diagram and outdoor equipment installation to self-supply power through the substation's self-use transformer.

The connection line section is to build a 220kV line, 4 circuits, with about 250m long, connecting to the Tuy Hoa - Nha Trang 220kV line.

The project aims to meet the load needs and ensure the operation of 110kV substations in the North of Khanh Hoa province and the South of Phu Yen province, especially supplying power to the load of Van Phong economic zone; ensuring stable power supply, meeting the socio-economic development needs of Khanh Hoa province.
