1、.多种类型自控系统在储气库系统集成中的应用摘要:某国家地下储气库,是将长输管道输送来的商品天然气重新注入地下空间而形成的一种人工气田。地下储气库具有以下优点:储存量大,机动性强,调峰范围广;经济合理,虽然造价高,但是经久耐用,工艺装置比较复杂,安全系数大,安全性远远高于地面设施。其装置的自动化控制选用多种类型控制系统相结合,发挥不同系统长处,实现储气库自动化安全生产,达到“集中管理,分散控制”的模式。This essay is about the installation and debugging of the automation system of a national undergro
