摘要
雪峰山隧道工程采用了专用光纤、以太网作为通信系统,专用的后台配电网自动化系统具有较为完善的构架。配电网络采用了双环网供电,在双环之间采用两路联络开关,其结构相对复杂。针对配网自动化系统故障诊断、隔离与网架重构进行了详细的论述,其中对外部电源故障实现配电自动化方案做了重点论述,此配网自动化实现方案可靠有效的实现了工程的配电网自动化,保证了整个供电系统的可靠运行。
This project uses a dedicated fiber optic,and uses Ethernet as communication system,a dedicated background distribution automation system has more comprehensive framework.Distribution network uses a loop network power,and uses two contact switches between the double-loops,and its structure is relatively complex.In this paper,the fault diagnosis,isolation and grid reconstruction of distribution automation system,including the distribution automation program achieved by external power failure are discussed in detail.The distribution automation for project is realized by this scheme reliably and effectively,and the reliable operation of the power supply system is ensured.
