The 210kV station was built at the total cost of more than 348 billion VND (15million USD) on an area of some 40,100 square metres spanning Dong Son and KenhGiang communes.
According to EVNNPT Deputy General Director Luu Viet Tien, the station helpedcut around 80 percent of the amount of copper cable, slash copper cabletransport and installation costs, while reducing the risks of incidents causedby cable damage.
Tien said that the digital transformer station is a new technology in bothVietnam and many developed countries in the world, adding before carrying outconstruction of the station, EVNNPT held several conferences with largeequipment suppliers such as Siemens, ABB and GE.
He said the 220KV digital station will ensure stable power supply forsocio-economic development in Thuy Nguyen district, Hai Phong city and regionsin 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 suitabletechnologies for transformer stations in the future.
The Vietnam Electricity Group (EVN) plans to have all equipment on transmissionlines and 80 percent of 110 kV circuit facilities digitalised from now to 2022.
By 2025, EVN willhave digitalised 100 percent of facilities on medium- and higher-voltage powerlines, according to EVN Chairman Duong Quang Thanh.
To that end, thegroup will press on with applying digital technologies like Internet of Things,big data, and cloud computing, he said, noting that it will use artificialintelligence (AI) in monitoring and examination and make use of cameras andsmart drones to repair lines.
It will continueresearch on building information models and digital worker platforms to serveits staff while developing AI applications for image analysis and datagovernance.
EVN said it hascompleted 61 of the 63 centres for remote control of transformer stations andconverted 670 of the 844 transformer stations into unmanned ones./.
