Vietnam’s National Power Transmission Corporation (EVNNPT) has put into operation its first digital substation in the northern port city of Hai Phong. The 220kV digital substation was built at the total cost of more than $15 million, on an area of approx. 40,000 sq meter.
According to EVNNPT, the digital technology helped cut around 80% of the amount of copper cable, slash copper cable transport and installation costs, while also reducing the risks of incidents caused by cable damage.
EVN has installed this substation to evaluate and analyze digital technology as it plans to digitise all equipment on transmission lines and 80% of 110 kV circuit facilities by 2022. By 2025, EVN will have digitalized 100% of facilities on medium- and higher-voltage power lines.
Moreover, EVN has recently completed remote control of 61 substations and converted 670 substations into unmanned ones in its network.
Owing to recent inclination of EVN towards digital technology, Vietnam is expected to be a major market of digital equipment and substation automation in the region.
