"With heavy rain and continuous precipitation expected recently, we must carefully inspect water accumulation in cable trenches and drainage ditches at substations, and promptly remove floating debris to ensure safe and stable equipment operation," said a staff member of Ruzhou Power Supply Company in Henan province on May 25, while conducting flood prevention inspections at substations within their jurisdiction, comprehensively fortifying the power grid's flood safety barrier.
In response to this round of heavy rainfall, the company took preemptive measures by immediately activating its flood emergency response mechanism. It scientifically deployed multiple safeguard measures, pre-established emergency repair teams, and fully prepared repair materials, vehicles, and flood control equipment. The company strictly implemented emergency duty systems to ensure personnel, materials, and vehicles were on standby at all times, laying a solid foundation for the safe and stable operation of the power grid.
In terms of equipment operation and maintenance, the company closely monitored weather changes and carried out work deployments in accordance with its summer peak load power protection plan. Leveraging a "three-dimensional inspection + centralized monitoring system", the company strengthened special patrols and protection of "three crossings" sections of transmission lines through drones and visual monitoring. It comprehensively inspected the operating status of key components such as towers, conductors, ground wires, insulators, vibration dampers, and spacers, promptly eliminating hidden hazards. Through a dual-line linkage model of "on-site special patrols + intelligent auxiliary control systems", the company monitored equipment operating conditions in real time during periods of strong winds and heavy rainfall while conducting comprehensive hidden danger inspections at substations. On-site inspections focused on the status of oil-filled and gas-filled equipment, the sealing performance of terminal boxes and mechanism boxes, and the clearing of debris from cable trenches and drainage channels to prevent risks of rainwater seepage and condensation. Additionally, the company adhered to the bottom line of ensuring power supply for people's livelihoods, prioritizing electricity supply for "lifeline" users such as hospitals, water and gas supply facilities, and transportation hubs, fully safeguarding reliable power supply for people's production and daily lives.
Going forward, Ruzhou Power Supply Company will continue to remain vigilant in flood prevention and power supply protection. The company will strengthen its safeguard measures across multiple dimensions including power grid dispatching, equipment operation and maintenance, and quality customer service, fortify the power grid safety barrier, and guarantee reliable electricity supply to thousands of households in Ruzhou.
