The Shaoguan Port Wushi Integrated Transportation Hub represents a significant investment in transportation infrastructure in Guangdong Province. The project is of significant scale and requires the stability and efficiency of the power system to be guaranteed. To address the challenges of fluctuating power loads and power quality issues, we provided 11,600 kvar high-voltage compensation cabinets to the project team, with a total of 86 units installed. Reactive power compensation technology stabilizes voltage, improves power factor, and ensures the efficient and stable operation of all electrical equipment in the transportation hub. The project has had a significant impact on improving energy efficiency and reducing operating costs, ensuring the efficient operation of the transportation hub.
