Dual-mode substation monitoring signal backup monitor and monitoring method

Abstract

The invention provides a dual-mode substation monitoring signal backup monitor and a monitoring method. The dual-mode substation monitoring signal backup monitor comprises an in-situ sampling module,a data processing module and a GSM module. According to the monitoring method of the invention, a substation signal is monitored and a fault signal is uploaded by means of two-way signal transmissionwhen a substation communication system is damaged, thereby enabling the maintenance personnel to handle emerging problems in time according to the signal alarm information, improving the reliability of the monitoring system, guaranteeing the efficiency, accuracy and timeliness of the fault processing process, and ensuring the safe, stable and reliable continuous power supply of the power grid.

Description

technical field [0001] The invention belongs to the technical field of substation signal monitoring, and in particular relates to a dual-mode substation monitoring signal backup monitor and a monitoring method. Background technique [0002] The substation monitoring system is a system information collection, processing and reporting system in the power system, which can provide necessary real-time or non-real-time operation information to the monitoring personnel, so that the duty personnel and system monitoring personnel can keep abreast of the operation of the substation. At present, most substations are unattended, and the traditional station-side monitoring method is replaced by the unified monitoring method of the monitoring center. The monitoring signal in the substation is the staff of the monitoring center to monitor the operation of various equipment in the substation and judge the operation of the equipment. basis and grounds. Once the substation signal monitoring...

AI Technical Summary

Problems solved by technology

Once the substation signal monitoring system fails, the corresponding fault or alarm signal cannot be collected, and the monitoring background cannot receive the signal, which will lead to some critical defects that cannot be dealt with in time, causing great harm to the power system

Due to the harsh operating environment of the monitoring system in the substation, system components are easily damaged, resulting in a large amount of system maintenance, and often important signals cannot be received in time, which seriously affects power reliability and safety.
