Siemens Energy Awarded Contract By TRE To Equip Two Wind Farms In Vietnam

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

The two wind farms, IaPet-Dak Doa 1 and IaPet-Dak Doa 2, which are located in the Dak Doa district of Gia Lai province in the country’s central highlands, will have a capacity of 100 MW 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.

Siemens Energy will equip the substation connecting the wind farm with the national grid.

The company will deliver, among other substation assets, digitally enhanced transmission products with advanced intelligence from the company’s Sensproducts portfolio, including connective circuit-breakers, surge arresters and power transformers. 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.

Duong Quynh Hoa, CEO of TRE, said in the December 2020 statement, in part: “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. 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.”

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 of these assets will be equipped with smart IOT (Internet of Things) technology and sensors to measure the most important operating parameters. The operator will be able to check the status of the substation assets via online applications in real time to increase efficiency and availability of operations. Additionally, the company will deliver conventional disconnectors, instrument transformers and current limiting reactors.

The energization of the substation is scheduled for August. 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 MWh annually.
