To meet the requirements of integrated function

networking control

and status visualization for the monitoring equipments in modernized intelligent substations

a new local cooler intelligent control device was designed to update the traditional cooler control devices.And a long-distance control and intelligent electronic monitoring device was also developed based on IEC 61850 protocol.This control system

to a great extent

improves security

stability and reliability of the transformers.The control system has been used in Lanxi 500 kV digital substation

which is one of the first pilot projects of intelligent substation in China.
