Method for automatically diagnosing remote-signaling data transmission failure of power grid energy manage 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 present invention relates to the field of industrial Internet of Things, in particular to a power system fault diagnosis technology. Background technique [0002] With the increasing complexity of the grid structure and the continuous expansion of grid capacity, the amount of information that needs to be transmitted in real time has increased exponentially. This puts forward the data communication of substation automation system (SAS, Substation Automation System) and energy management system (EMS, Energy Management System) higher requirement. In order to ensure the normal operation of the SAS system and the EMS system, complete, safe and correct automated scheduling is essential. [0003] In the field of dispatch automation system communication, systems or equipment exchange information through communication protocols, which are the basis for the realization of system functions. Due to the mistransmission of data by communication channels or equipment,...
