Abstract

The invention discloses an intelligent substation merging unit one-button type communication loop verifying method. The intelligent substation merging unit one-button type communication loop verifying method comprises the steps that a substation monitoring background system triggers the sampling value number setting function of a merging unit; the merging unit sends a sampling value message with repairing quality to a protection control device; the protection control device conducts protection distinguishing and sends a trip GOOSE message with the repairing quality to an intelligent terminal; the intelligent terminal does trip actions and feeds the outlet state back to the substation monitoring background system through a trip feedback GOOSE message; the substation monitoring background system judges the correctness of action behaviors according to an action instruction and the trip feedback GOOSE message, and a closed loop test is formed. By means of the method, single protection and verification of related communication loops can be quickly and automatically finished under the situation that a secondary loop of a current intelligent substation protection control system is not damaged.

Description

technical field [0001] The invention relates to a one-button communication loop verification method for a merging unit of an intelligent substation, and belongs to the technical field of substation operation, maintenance and repair. Background technique [0002] In the long-term operation experience of microcomputer protection, it can be found that the demand for the function calibration of professionally tested relay protection devices in actual operation and maintenance is reduced, and the reliability and stability of protection and control systems are often determined by the reliability of related communication circuits. . Due to the non-intuitive visibility of the communication circuit of the smart substation and the greatly improved technical ability requirements for the operation and maintenance personnel, it has also caused difficulties in the communication verification of the current smart substation protection control system. [0003] Ordinary smart substations are...
