The invention discloses a remote online monitoring and state evaluating
system used for a
transformer substation, and belongs to the technical field of
power grid communication. The
system comprises a monitoring sub
system, a collection sub system, an evaluation sub system and a publishing sub system. A fault filter of the monitoring sub system is used for recording and collecting monitored data; the fault filter transmits and stores the monitored data collected by the fault filter in a storage
server of the collection sub system through a communication
server; the evaluation sub system extracts the monitored data and performs comparison and analysis with a pre-predicted key data to determine the state of the
transformer substation, and then transmits the determined state
evaluation result to a working staff of the
transformer substation through the publishing sub system, so that onsite construction can be avoided; the
equipment state of the transformer substation is determined through
remote evaluation, so that the previous manpower multiple-point and aimless inspection way can be eliminated; and the remote online monitoring and state evaluating system has the characteristics of high automatic degree, high efficiency and high response.
