A method for automatically diagnosing faults in remote signaling data transmission of power grid ems system

Abstract

The invention discloses a method for automatically diagnosing remote-signaling deflection data transmission failure of a power grid energy manage system (EMS). The method comprises the steps: through monitoring each protecting / measuring intelligent electronic device (IED) of a factory station, telecontrol equipment, an exchanger and a pre-communicator of a master station in real time, after monitoring that the remote-signaling data value is changed, triggering the remote-signaling failure and error report detection flow, detecting whether the remote-signaling data M2 at the telecontrol equipment side, the remote-signaling data M3 at the exchanger side, and the remote-signaling data M4 at the master station pre-communicator side of the same measuring object are normally obtained after receiving the remote-signaling data M1 at the IED side, and judging whether the values of the M1, M2, M3 and M4 are the same; according to the monitoring result, generating the remote-signaling failure and error report warning of the corresponding device; and discovering the existent remote-signaling failure and error report situations in the EMS system in first time, and automatically accurately positioning the failure report or error report node. The transmission accuracy of the measuring information in the power grid EMS is ensured, and the load of the operator is greatly relieved.

Description

technical field [0001] The invention relates to the field of industrial internet of things, in particular to a power system fault diagnosis technology. Background technique [0002] As the power grid structure becomes more and more complex, the capacity of the power grid continues to expand, and the amount of information that needs to be transmitted in real time increases exponentially. high demands. In order to ensure the normal operation of the SAS system and EMS system, perfect, safe and correct automatic scheduling is essential. [0003] In the field of dispatch automation system communication, information exchange is carried out between systems or devices through communication protocols, which are the basis for the realization of system functions. Due to the communication channel or equipment mistakenly sending data, in the dispatching automation system, remote signal false positives, missed reports, remote control cannot be executed or executed incorrectly, and telem...
