220kV智能变电站过程层网络设计研究

摘要

Based on the features of the 220 kV smart substa-tion process layer network general design schemes ,intro-duces the optimization scheme of process layer network and switch configuration ,analyses the characteristics and infor-mation exchange requirements of 220 kV and 110 kV sys-tem ,demonstrates the branch process layer switch and cen-ter process layer switch configuration scheme ,puts forward the principle that should be observed when multiple center sw itchs are cascaded .%根据220 kV智能变电站过程层网络通用设计方案的特点，介绍过程层组网和交换机配置的优化方案，分析变电站220 kV、110 kV系统的特点和信息交换需求，论证过程层子交换机和中心交换机的配置方案，提出多台中心交换机级联时应遵守的原则。
