Vietnam’s National Power Transmission Corporation (EVNNPT) has put into operation its first digital transformer station in the Thuy Nguyen district of the northern port city of Hai Phong.

The 210kV station was built at a total cost of over $15 million on an area of 40,100 square metres spanning Dong Son and Kenh Giang communes.

According to EVNNPT Deputy General Director Luu Viet Tien, the station helped cut around 80% of the amount of copper cable, slash copper cable transport and installation costs, while reducing the risks of incidents caused by cable damage.

Tien said the 220KV digital station will ensure a stable power supply for socio-economic development in Thuy Nguyen and regions in the vicinity, reduce power loss as well as enhance connectivity, safety, stability and flexibility in the operation of the power system.

The Vietnam Electricity Group (EVN) plans to digitise all equipment on transmission lines and 80% of 110 kV circuit facilities by 2022.

By 2025, EVN will have digitalised 100% of facilities on medium- and higher-voltage power lines, according to EVN Chairman Duong Quang Thanh.

EVN said it has completed 61 of the 63 centres for remote control of transformer stations and converted 670 of the 844 transformer stations into unmanned ones.
