The 210kV station was built at the total cost of more than VND348 billion (US$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 that the digital transformer station is a new technology in both Vietnam and many developed countries in the world, adding before carrying out construction of the station, EVNNPT held several conferences with large equipment suppliers such as Siemens, ABB and GE.
He said the 220KV digital station will ensure 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 operation of power system.
EVNNPT will make evaluation on the efficiency of the station so as to select suitable technologies for transformer stations in the future.
The Vietnam Electricity Group (EVN) plans to have all equipment on transmission lines and 80% of 110 kV circuit facilities digitalised from now to 2022.
By 2025, EVN will have digitalised 100% of facilities on medium- and higher-voltage power lines, according to EVN Chairman Duong Quang Thanh.
To that end, the group will press on with applying digital technologies like Internet of Things, big data, and cloud computing, he said, noting that it will use artificial intelligence (AI) in monitoring and examination and make use of cameras and smart drones to repair lines.
It will continue research on building information models and digital worker platforms to serve its staff while developing AI applications for image analysis and data governance.
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.
