Yesterday, construction work began on the Guantang 220kV Substation in Qiujia River Bend, Huahu Town, Ezhou City. This groundbreaking project represents Ezhou's first-ever 220kV substation, is built with the city's technical expertise. Notably, it also marks the debut of a smart construction site for substation projects in Ezhou.
The substation spans across a 23-mu area (1 mu=approximately 0.13 km2), with the underground foundation work nearing completion. Construction has commenced on the supporting transmission line towers. The substation will house a single 240MVA (Megavolt-Ampere) transformer, establishing connections to both the Ezhou-Wudu 500kV Substation and the Ezhou-Shatang 220kV Substation.
At the construction site, the reporter observed that the progress of the construction could be monitored through both the surveillance camera and mobile devices. Project manager Wu Bin explained, "Even actions like smoking or not wearing safety helmets by the construction workers are automatically detected and recorded as violations. Furthermore, the construction site can be monitored and reviewed through the surveillance system of the provincial and municipal companies of State Grid."
The Power Grid Construction Branch of Ezhou Electric Power Co., Ltd has successfully transformed traditional distribution boxes into a power control system using Internet of Things (IoT) technology. This innovative system is being implemented for the first time at this construction site. Wu Bin, a key participant in this technological advancement, explains, "The power control system allows for comprehensive management and control of the construction power supply, effectively eliminating the safety risks associated with live electricity during construction." In addition, Wu Bin mentions that outdoor environmental monitoring devices will be installed to track dust, noise, and meteorological factors, while facilities like spray fences will be implemented for dust suppression. These measures aim to ensure environmentally friendly construction.
The construction project is scheduled to be finished and operational by mid-2024, according to the plan. Once completed, it will serve as a new access point for 110 kV substations, including Ezhou Huahu Airport. Moreover, it will contribute to the improvement of the power grid infrastructure in the eastern region of our city, ensuring an ample power supply for the growth of the airport-based industry. Wu Bin mentioned, "Additionally, we will submit an application for the State Grid Quality Engineering Gold Award".
