Embodiment Construction

[0081] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0082] A fault diagnosis and location method for tripping and closing monitoring is realized based on an intelligent wave recording system, which is a system well known to those skilled in the art. The intelligent wave recording system includes three parts: a management unit, an acquisition unit and a switch. The management unit is connected to the network switch of the intelligent substation station control layer through the switch to monitor and obtain the start signal of the protection device and the action signal of the protection device. The acquisition unit is connected to t...

Abstract

The embodiment of the invention provides a fault diagnosis and positioning method for tripping and closing monitoring, and belongs to the technical field of power grids. The fault diagnosis and positioning method comprises the steps of judging whether a protection device starting signal is received or not; when it is judged that the protection device starting signal is received, obtaining an action MMS signal; judging whether the action MMS signal is received or not; and under the condition of judging that the action MMS signal is received, acquiring a tripping and closing GOOSE signal. The invention provides a fault diagnosis and positioning method for tripping and closing monitoring. A tripping and closing GOOSE signal, an intelligent terminal tripping and closing reverse correction GOOSE signal, a recovery confirmation signal and a circuit breaker position GOOSE signal are monitored through a tripping and closing monitoring reference template, and the fault diagnosis and positioning are carried out through judging the displacement state and displacement time of each signal, so that the workload of troubleshooting of operators is reduced, and the efficiency of troubleshooting is improved.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a fault diagnosis and location method for tripping and closing monitoring. Background technique [0002] Different from the traditional substation protection device tripping and closing action output electrical signal, the tripping and closing of the protection device in the smart substation outputs the GOOSE signal, which makes the tripping and closing circuit from the protection device to the circuit breaker more intelligent terminals. conversion link. For a complete tripping and closing, it is necessary to ensure that the tripping and closing GOOSE signal is sent from the protection device, through every step from the smart terminal to the circuit breaker, the signal is sent and received correctly, and the action time is within the required range. In the process of tripping and closing, by collecting relevant GOOSE and MMS signals during the tripping and closing process, ...
