揭秘公祭伏羲大典背后的电力科技

Core Viewpoint - The article highlights the innovative power supply assurance strategy implemented by State Grid Tianshui Power Supply Company during the national cultural ceremony, showcasing advancements in technology and a comprehensive power supply system [1][3]. Group 1: Technological Innovations - The most significant technological breakthrough is the large-scale application of Static Transfer Switch (STS) devices, which achieve a switching speed of 15 milliseconds, providing a 20-fold efficiency improvement over traditional Automatic Transfer Switch (ATS) devices that switch in seconds [3]. - The deployment of STS devices expanded from a single unit last year to multiple units covering five core areas, creating a redundant network for rapid power switching [3]. - A modular design of the new UPS mobile uninterruptible power supply system offers "zero-second" continuous power supply for critical loads such as lighting and broadcasting equipment [3][5]. Group 2: Monitoring and Response Systems - An IoT-based intelligent monitoring platform acted as a "power sentinel," scanning seven monitoring points at a frequency of ten times per second, triggering alarms for temperature thresholds or partial discharge events [4]. - The emergency response process can be compressed to under three minutes, allowing for early diagnosis of potential issues, akin to equipping power devices with a CT scanner [5]. - The new power supply assurance system has been operational for 96 hours, successfully handling one early warning event, and demonstrated a switching speed of 13.8 milliseconds during a simulated main power interruption [5]. Group 3: Future Applications - The technologies used in this power supply assurance, such as STS and intelligent fusion terminals, will be standardized and promoted for other major event power supply scenarios, creating a replicable and iterative technical solution library [5].
