Siemens Energy has been awarded a contract by Technology Resources Energy (TRE) to equip two onshore wind farms in Vietnam with digitally enhanced transmission equipment, including five power transformers.

The scope of supply of connective transmission equipment includes three units of 500 kV and two units of 220 kV power transformers, three 500 kV and six 200 kV circuit-breakers with advanced trending as well as 15 surge arresters rated at 500 kV. All these assets will be equipped with smart IOT (Internet of Things) technology and sensors to measure the most important operating parameters.

Equipped as Sensformer Advanced units, the transformers come with a digital twin, a synchronized thermo-replication of the physical asset, that will allow the operator to manage temporary overloads without compromising on lifetime. 

The two wind farms IaPet-Dak Doa 1 and IaPet-Dak Doa 2 are both located in the Dak Doa district of Gia Lai province in the country’s central highlands and will have a capacity of 100 megawatts each. The wind farms are part of Vietnam’s ongoing Power Development Master Plan to further push the integration of renewable energy sources and to enhance the power supply. 

“The Dak Doa wind farm project is another excellent project demonstrating how digitalization is providing the technical basis for the most efficient use of renewable energy sources,” says Beatrix Natter, Executive Vice President Transmission at Siemens Energy.

“Once completed, the IaPet Dak Doa substation will be operated with two transformer banks of 900MVA capacity each and become the key to both north and south grid system,” said Duong Quynh Hoa, CEO of TRE.

“Located right next to the existing Pleiku 2 substation which is also being upgraded, the total capacity of both combined substations will make this the biggest connection point in terms of capacity throughout Vietnam. For that reason, we have opened the bid to select the best solutions and are very grateful to award the contract to Siemens Energy. We hope that Siemens Energy’s consistent quality and excellent services shall bring success to the long-term operation of our wind farm and the 500-kilovolt substation,” she added.

At the IaPet-Dak Doa one and IaPet-Dak Doa two wind farms a total of 44 wind turbines will be installed. They are expected to generate a gross energy of about 532,622 megawatt hours annually. The energization of the substation is scheduled for August 2021.
