Quzhou, Zhejiang : Strengthening Flood Dikes and Securing Power Supply During the Plum Rain Season in Jiangnan

The plum rain season in Jiangnan coincides with the critical period of rising water levels during the flood season. In Quzhou, Zhejiang Province, the State Grid Quzhou Power Supply Company has proactively entered a state of heightened readiness. The company has established a flood prevention and power supply emergency response team, activated its severe weather emergency mechanism, and adopted a combined “drone + manual” three-dimensional inspection model to carry out special patrols of its transmission lines and substations.

During these special patrols, the flood prevention and power supply team was dispatched to the frontlines, organizing into smaller groups based on local power supply stations to carry out power security inspections during the flood season. The inspections focused on key areas, especially low-lying zones prone to waterlogging and other high-risk sections, to ensure timely identification and mitigation of safety hazards. “This line runs along the Longshan Stream. During the inspection, please pay close attention to the stability of poles and guy wires along the riverbank. Any hazard must be addressed immediately,” emphasized the team during a pre-operation briefing on June 15 in Changhong Township, Kaihua County. Following the briefing, the inspection team split into three groups, each assigned with specific tasks. Extra caution was urged during riverbank patrols, with a focus on monitoring for potential landslides and ensuring the stability of embankments.

In this special inspection campaign, the State Grid Quzhou Power Supply Company concentrated its efforts on thoroughly inspecting substations within its jurisdiction. Key components such as drainage systems, cable trenches, equipment sealing integrity, and surrounding slopes and retaining structures were subjected to a comprehensive grid-style inspection. Advanced technologies such as infrared thermography and drone surveillance were employed to monitor the real-time operational status of equipment. In addition, flood emergency drills simulating extreme weather scenarios were conducted to ensure rapid response to sudden incidents.

“We have now completed all emergency response plans, stocked necessary flood prevention supplies, and carried out thorough inspections of all equipment,” said Zhang Junbo, an operations and maintenance technician at the company. He added that staff members have gone deep into the countryside and fields to conduct solid flood prevention work, striving to enhance both the speed and quality of the power grid’s emergency response, ensure safe and stable grid operation during the plum rain season.
