LNG气化站供配电方案选择及设计的浅析

Design of Power Supply and Distribution Scheme for LNG Station

LNG气化站是一个接收、储存和分配LNG的卫星站,也是城镇或燃气企业把LNG从生产厂家转往用户的中间调节场所,其电源的供电可靠性决定了LNG气化站是否可以正常运行给区域内的用户提供燃气。文章总结了LNG气化站的供配电设计中负荷等级的确定、供配电方案的选择,以及自备柴油发电机的容量选择及考虑因素,为今后相关设计提供参考及借鉴。

The main function of LNG station is to receive, store and distribute LNG, which is the intermediate adjustment link of gas supply chain.The reliability of power supply in the station determines whether it can operate normally.This paper summarizes the determination of load grade, the selection of power supply and distribution scheme, and the capacity selection and consideration factors of theautonomous diesel generator, which will provide reference for the future design.
