With the application and development of integrated substation automation technology
a lot of substations are being put into operation with unattended; Effective maintenance of integrated substation automation systems is the foundation to ensure the normal operation of dispatching automation system. Here
aflexible and practicable remote maintenance scheme based on local monitoring system and remote desktop is proposed
in which the computer technology and digital communication network technology are utilized
The proposed scheme can realized a remote maintenance for Substation Automation and improve the operation reliability of power network dispatchingautomation system by remote controlling Local monitoring system.
