Quanganhcons contractor is specialized in designing and constructing modern substations in Quang Ngai, meeting high technical and safety standards.
Design and Construction of Substations with New Technology
Quanganhcons substation contractor in Quang Ngai is a leader in the field of designing and constructing substations up to 35kV, including pole substations, platform substations, single-pole tower substations, ground substations, room substations, and combined kiosks. With modern technology and a team of experienced engineers, Quanganhcons ensures quality, safety, and long-lasting efficiency of the works. These substations effectively serve key industrial zones like Dung Quat Economic Zone.
The design and construction of substations with new technology are becoming increasingly important to ensure the electrical capacity serves economic development. The current trend focuses on grid automation, digitalization, and improving operational efficiency to meet safety and grid stability requirements.
Modern unmanned substations are replacing traditional models, managed remotely via SCADA systems. This includes monitoring and controlling equipment through telecommunications networks, reducing operational costs, and enhancing labor safety by minimizing risks of human error. Automation technology supports quick and timely data retrieval, combined with surveillance cameras and electronic data storage. This transition started in 2016 and is now steadily being widely adopted.
In terms of design, improving substation capacity is necessary, for example, upgrading transformer capacity from 220kV-125MVA to 250MVA or 500kV-1,350MVA. This process goes along with completing connecting systems, installing new output bays, and control – protection systems, and water mist fire protection systems. These items ensure safe and stable long-term operation of the transmission power system.
Additionally, shunt capacitors are installed at major substations like 220kV, 500kV to improve power supply and transmission capability, balance voltage, and reduce power losses, especially during hot months. Shunt capacitor projects are often implemented synchronously across many substations to enhance the efficiency and reliability of the power grid.
These new technologies not only improve operational efficiency but also create an optimal foundation for expanding the national power grid in the future, strongly supporting the increasing electricity demand.
