This is the first digital transformer station invested by the National Power Transmission Corporation (EVNNPT), and is also the first 220kV digital transformer station in the country.

Thuy Nguyen 220kV substation (TBA) includes 2 transformers (MBA) 220/110 / 22kV – 250MVA, and in this phase, 1 transformer will be installed. The 220kV side uses the diagram of two busbar systems with a ring busbar with 12 compartments. In this stage, equipment is installed for 7 lanes. The 110kV side uses the diagram of two busbar systems with a ring busbar with 21 compartments. In this stage, equipment is installed for 13 lanes. The station has an area of ​​about 40,100 m2 located in Dong Son commune and Kenh Giang commune, Thuy Nguyen district, Hai Phong city. This is a class I energy project of group B, with a total investment of more than 348 billion dong, invested by EVNNPT, the project is managed by NPMB, and operated by Power Transmission Company 1. Mr. Pham Le Phu, General Director of EVNNPT, said: Digital substations are not only new technology for Vietnam but also advanced countries. Before implementing the project, EVNNPT held many seminars with major equipment manufacturers in the world such as Siemens, ABB, and GE, but the number of 220kV substations was the same size as Thuy Nguyen 220kV substations using TBA technology. number is very few. Thuy Nguyen 220kV substation has the advantages of reducing copper cable by about 80%; reduce transportation, construction and installation of copper cables and reduce the area of ​​cable trenches; reduce the installation space of control and protection devices. Thuy Nguyen 220kV substation will ensure power supply for additional loads and meet socio-economic development needs of Thuy Nguyen district, Hai Phong city and surrounding areas, reduce power loss and strengthen connectivity. safe, stable and flexible in operating the power system.

Hai Phong. This is the first digital substation project invested by the National Power Transmission Corporation (EVNNPT).
Thuy Nguyen 220 kV substation consists of 2 transformers 220/110/22 kV-250 MVA, in this phase, one transformer will be installed. The 220 kV side uses the diagram of two busbar systems with a ring busbar with 12 compartments. In this stage, equipment is installed for 7 lanes.

The 110 kV side uses the diagram of two busbar systems with a ring busbar with 21 compartments, in this stage, installing equipment for 13 lanes. Thuy Nguyen 220 kV substation has an area of ​​about 40,100 m2 located in the area of ​​2 communes Dong Son and Kenh Giang, Thuy Nguyen district, city. Hai Phong. This is a class I energy project of group B, with a total investment of more than 348 billion dong, invested by EVNNPT, the project is managed by NPMB, and operated by Power Transmission Company 1. Thuy Nguyen 220 kV substation is the first substation in Vietnam. Photo: VGP According to Mr. Luu Viet Tien, Deputy General Director of EVNNPT, Thuy Nguyen 220 kV substation has the advantages of reducing about 80% of the copper cable; reduce transportation, construction and installation of copper cables and reduce the area of ​​cable ditch; reduce the installation space of control and protection devices. Mr. Tien also added that digital TBA is not only a new technology to Vietnam but also to advanced countries. Before implementing the project, EVNNPT held many seminars with major equipment manufacturers in the world such as Siemens, ABB, GE … however the number of 220 kV substations was similar in scale to the 220 kV Thuy Nguyen substations used for Current digital TBA technology is very few. The power supply and operation of the 220 kV Thuy Nguyen substation will ensure the power supply for the load and meet the socio-economic development needs of Thuy Nguyen district, city. Hai Phong and its surrounding areas, reduce power loss and strengthen connectivity, safety, stability and flexibility in power system operation. At the same time, in the process of investing and operating the 220 kV Thuy Nguyen substation, EVNNPT will summarize and evaluate the advantages, disadvantages, benefits, costs and investment efficiency of digital substations to serve as a basis for decision. select control technology, protect TBA in the future.
