Finally, the techno-economic criteria of design and operation of non-attended substation using integrated automation system are discussed.
The operational aspect of the video surveillance system indicates that it is a powerful tool of the remote monitoring for the non-attended substation.
This paper deals with the design principle, the system structure and the selection of the equipment for remote video surveillance system with regard to the present operational management mode in non-attended substation.
The development of automatic reclosing made the unattended substation practical.
Once the unattended substation became a reality, the substation could be made smaller, located nearer the load, and long feeders were no longer necessary.
The paper analyzed the necessity, retrofit mode and its comparison for unattended substation, and explained that the integrated automation is the inevitable tendency of retrofit for unattended substation.
Actuality and suggestions for the reconstruction of integrated automation in 110kV unattended substation
