电化学储能电站总平面布局要点

Group 1: Overall Layout - The overall layout of electrochemical energy storage stations should prioritize the orientation of outgoing lines and access roads, with overhead lines preferred for outgoing connections to minimize path length and crossings with existing infrastructure [4][12] - The layout is divided into three main functional areas: the booster station area, storage area, and office/living area, with effective isolation through circular roads to minimize noise and electromagnetic interference [4][12] Group 2: Fire Safety - Fire safety is critical for lithium-ion battery storage stations, with national standards (GB/T 51048-2025) specifying fire distance requirements, such as a minimum of 20 meters from battery rooms to main buildings and 25 meters to transformers [5][13] - Additional fire distance requirements include a minimum of 3 meters from battery rooms to external roads, with firewalls required if distances are insufficient [6][14] - Fire partitioning is necessary, with each partition generally not exceeding 50 MWh and a minimum distance of 10 meters between adjacent partitions, with stricter requirements in regions like Inner Mongolia [7][15] Group 3: Operation and Maintenance - The layout must accommodate equipment transport, installation, and maintenance, with a minimum distance of 3 meters between battery rooms, allowing adjacent placement under specific conditions [8][16] - Internal roads must support the transport of large equipment and meet fire safety requirements, with a minimum width of 4 meters for circular fire lanes and a turning radius of at least 9 meters [8][16] - Battery rooms are typically single-layered, with double-layer arrangements requiring advanced structural support and access provisions [8][16]
