Problems solved by technology

[0003] In the process of long-term operation, the fault recorder may have defects such as failure to record waves, inability to retrieve recorded waves from a remote location, communication interruption, device crash, etc. According to statistics, most of the defects of the fault recorder itself can be recovered by restarting
The existing restart method usually requires the operation and maintenance personnel to go to the fault site to hard reset the fault recorder, that is, to directly cut off the power supply and then reconnect the power supply. On the one hand, the remote location of most fault sites reduces the restart time. Efficiency, on the one hand, frequent hard restarts are likely to cause damage to the fault recorder and affect the service life of the fault recorder

Embodiment 1

[0054] like figure 1 As shown, the present invention proposes a remote restart method for a fault recorder, including:

[0055] S1: Monitor the heartbeat signal of each fault recorder through the recorder master station.

[0056] Based on the 61850 protocol, establish an ad hoc network between the recording master station and each fault recorder, and receive the heartbeat signal of each fault recorder through the ad hoc network.

[0057] In this embodiment, the topology of the ad hoc network is as follows figure 2As shown, the self-organized network is centered on the wave recorder master station, which is respectively connected with several fault recorders. The wave recorder master station in the self-organized network is used to send a restart command, and the restart command includes a soft restart command and For the hard restart command, the fault recorders are set in different substations, corresponding to the power grids of different partitions. An intelligent micro...

Embodiment 2

[0079] like image 3 As shown, the present invention proposes a remote restart system 5 for a fault recorder, comprising:

[0080] Monitoring unit 51: used for monitoring the heartbeat signal of each fault wave recorder through the wave recorder master station. Specifically for:

[0081] Based on the 61850 protocol, establish an ad hoc network between the recording master station and each fault recorder, and receive the heartbeat signal of each fault recorder through the ad hoc network.

[0082] In this embodiment, the topology of the ad hoc network is as follows figure 2 As shown, the self-organized network is centered on the wave recorder master station, which is respectively connected with several fault recorders. The wave recorder master station in the self-organized network is used to send a restart command, and the restart command includes a soft restart command and For the hard restart command, the fault recorders are set in different substations, corresponding to t...

Abstract

The invention provides a remote restart method and system for a fault recorder. The remote restart method includes: monitoring the heartbeat signal of each fault recorder through a main wave recorder; determining the fault recorder to be restarted based on the monitoring results Wave recorder to determine the unit that needs to be restarted in the fault recorder to be restarted; if the unit to be restarted is a wave recorder, send a soft restart command to control the wave recorder to the management unit. When the soft restart command is invalid, directly to the recorder The wave unit sends a hard restart command; if the unit that needs to be restarted is the management unit, it sends a hard restart command to the management unit. Combining soft restart and hard restart, and supports restarting some functional modules independently, while realizing sub-module restart, the number of hard restarts is reduced, the hardware damage of the fault recorder caused by frequent restarts is avoided, and the fault recorder is prolonged. service life.

Description

technical field [0001] The invention belongs to the field of remote restart, and in particular relates to a remote restart method and system for a fault recorder. Background technique [0002] The fault recorder is an automatic device that records the dynamic process of the entire electrical quantity change when the power system fails or oscillates, and provides a basis for the analysis of abnormal conditions. The fault wave recorder is generally composed of two units: a wave recorder unit and a management unit. The wave recorder unit collects and stores the data waveform triggered by the device during operation and the continuously recorded data changes through the built-in acquisition card. The management unit integrates human-machine interface and The communication module realizes the functions of wave recording information transmission, waveform viewing, parameter setting and controlling the start of the wave recording unit. [0003] During the long-term operation, the ...
