Abstract

A relay protection fiber channel intelligent monitoring system comprises a merging unit, a protection device, an intelligent terminal, a switch and a monitoring device, wherein the protection device is connected with the merging unit through an optical fiber, and the intelligent terminal is connected with the protection device through an optical fiber. The switch is an optical fiber switch and is respectively connected with the merging unit, the protection device, the intelligent terminal and the monitoring device so as to monitor optical fiber channels among the merging unit, the protection device and the intelligent terminal and send optical fiber channel monitoring information to the monitoring device to be displayed. A local monitoring device of an intelligent substation is provided with optical fiber chain scission photon boards, corresponding optical fiber chain scission photon boards flicker once optical fiber chain scission faults occur, and operation and maintenance workers can perform quick positioning on faulted optical fibers.

Description

technical field [0001] The invention relates to a monitoring device for an optical fiber channel in an intelligent substation, in particular to an intelligent monitoring system for a relay protection optical fiber channel. Background technique [0002] With the development of power systems, smart substations are increasing. Different from conventional substations, optical fibers are used in smart substations instead of traditional secondary cables. The introduction of optical fibers greatly reduces traditional secondary wiring. According to human observation, once the fiber channel breaks down, it will affect the data sampling and output of the protection device, causing the protection to malfunction or refuse to operate. The traditional fiber channel monitoring method generally adopts the method of uploading messages, but there are many devices in the substation, and the fiber channel monitoring information is easily submerged in the cumbersome message information, and it i...
