Vietnam’s National Power Transmission Corporation (EVNNPT) has operationalised its first digital transformer station in Thuy Nguyen district, the northern port city of Hai Phong, earlier this week. The 210kV station was built at a total cost of around VND348 billion (US$15 million) on an area of 40,100 square metres spanning the 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, and reduce the risks of incidents caused by cable damage. The system will use artificial intelligence (AI) in monitoring and examining and make use of cameras and smart drones to repair lines.

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

EVNNPT will evaluate the efficiency of the station 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, EVNNPT will have digitalised 100% of facilities on medium and higher-voltage power lines, according to EVNNPT Chairman Duong Quang Thanh. To that end, the group will continue to integrate other digital technologies like the Internet of Things, big data, and cloud computing.

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

Tien said that the digital transformer station is a new technology in both Vietnam and many other countries in the world. He added that before the station was constructed, EVNNPT held several conferences with large equipment suppliers such as Siemens, ABB, and GE.

Recently the Minister of Information and Communications (MIC), Nguyen Manh Hung, claimed that digital transformation and innovation will turn Vietnam into a developed country by 2045. He said that innovation always has to start with awareness and thinking and has to be seen from different perspectives. Old infrastructure, old ways of doing things, old knowledge, old products, old business models are no longer suitable. The country needs new infrastructure, new ways of doing things, new knowledge, new products, new business models.

That is why many people say that digital transformation is more of a policy revolution than a technology revolution. Adopting new business models, new technologies that fundamentally change industries. “If we are open to accepting the new, then the new technology of the world will come, talent from all over the world will come, a new industry will emerge and the cradle of Vietnam will create exportable digital technology products,” he noted.
