State Grid Yancheng Power Supply 500 kV Substation Operation and Maintenance Center: Weaving a Dense

To further enhance the station's security capabilities and emergency response level, comprehensively test the station's gate management, on-site coordination and emergency response capabilities, and strengthen employees' safety awareness, the Pandang Maintenance Team of the 500 kV Substation Operation and Maintenance Center of State Grid Yancheng Power Supply Company recently organized an anti-terrorism emergency drill at the Pandang Substation. Afterwards, the team conducted a debriefing and summary, and identified and addressed any shortcomings.cordless stick vacuum China

　　Many people believe that power grid security only concerns switching operations and accident handling, neglecting the "first line of defense"—substation security. A 500 kV substation is a crucial node in the regional backbone power grid. If it suffers sabotage or illegal intrusion, it can cause localized power outages at best, and at worst, jeopardize core equipment such as main transformers and circuit breakers, and even the stable operation of the power grid. In recent years, anti-terrorism standards in the power system have been continuously refined, requiring key target locations to organize at least one anti-terrorism education and training session and practical drill annually. Security personnel must be certified and undergo regular background checks. External personnel and vehicles entering the station must have their identities verified, be registered, and undergo security checks; those without work permits, accompaniment, or registration are strictly prohibited from entering.

　　From the pre-rehearsal briefing on regulations to the hands-on practice with riot control equipment, from the initial response by gatekeepers to the maintenance team's completion of the assigned tasks for security and coordinated control, the entire process tested not only individual courage but also the speed of information transmission, equipment readiness rate, and teamwork. The Pandang maintenance team of the 500kV substation maintenance center of the State Grid Yancheng Power Supply Company adhered to the golden principle of "initial self-protection, simultaneous control and reporting, and waiting for support"—immediately triggering a one-button alarm or dialing 110 upon discovering an anomaly and simultaneously reporting to the control center and safety supervision department. Security and maintenance personnel used riot control formations to buy time and protect key areas such as the main control room from breaches, resolutely avoiding blind confrontations by individuals that could escalate the damage.Cordless Vacuum Cleaner China

　　It is worth noting that modern substation security is rapidly upgrading towards "intelligentization + police-enterprise collaboration." Many 500kV substations have been connected to the public security internal security platform, and the linkage between electronic pulse fences, radar intrusion detection, and video surveillance can push alarms to the monitoring center in milliseconds. Some units have also established a "one station, one police officer" liaison mechanism with local police stations and conducted regular joint anti-terrorism drills to ensure seamless internal and external coordination in critical moments. For maintenance personnel, in addition to mastering professional skills such as switching operations and temperature measurement during inspections, possessing basic security literacy—identifying suspicious persons and items, being proficient in using riot control equipment, and being familiar with emergency evacuation routes and alarm procedures—is also an indispensable hard skill for substation maintenance in the new era.

　　Therefore, we should emulate the State Grid Yancheng Power Supply Company's 500kV substation operation and maintenance center by incorporating counter-terrorism and prevention into our annual emergency drills, regularly conducting joint police-enterprise exercises, continuously improving contingency plans, and addressing shortcomings. With a robust system of human, technological, and physical defenses, we must fully solidify the safety defenses of the 500kV power grid in the Yancheng area, adding an invisible yet indestructible shield behind the lights of countless homes.
