Remote intelligent monitoring method and equipment for transformer substation alternating current and direct current system faults

Abstract

The invention discloses a remote intelligent monitoring method and equipment for transformer substation alternating current and direct current system faults. The equipment includes a module information acquisition unit, a remote monitor, a cloud server and a control terminal. The module information acquisition unit includes a charging module monitoring unit and a relay therein, the relay in the charging module monitoring unit is connected with the output end of a charging module and detects voltage and current information of the output end, the charging module monitoring unit is connected withthe remote monitor through a serial communication isolator in a multi-dry contact input mode, the remote monitor includes a processor, a protocol switching box and an antenna which are connected in sequence and is connected with the cloud server and a mobile phone in a wireless communication mode, and the cloud server is connected with the control terminal formed by a PC and a mobile phone APP; and running data of a transformer substation alternating current and direct current power supply are remotely monitored, so that operation and maintenance personnel comprehensively master the running condition of the transformer substation, thereby improving the stability of safe operation of the system.

Description

Technical field: [0001] The invention relates to a monitoring device, in particular to a remote intelligent monitoring method and device for a substation AC / DC system fault. Background technique: [0002] At present, more and more substations are unattended, and many monitoring data and alarm information have not been transmitted remotely, resulting in untimely defect handling and affecting the safe operation of substations. [0003] At present, all the signals and data of the substation are uniformly monitored through the background computer. The large amount of data and many alarm signals are not conducive to classified and targeted maintenance for DC power failures. Coupled with the lack of some DC signals, the maintenance personnel are not fully prepared, and the repetitive running around increases the workload. Invention content: [0004] The technical problem to be solved by the present invention is: to overcome the deficiencies of the existing technology, to provid...
