Master monitoring device of AC/DC (Alternating Current/Direct Current) integration power supply

Abstract

The invention discloses a master monitoring device of an AC / DC (Alternating Current / Direct Current) integrated power supply. The master monitoring device of the AC / DC integration power supply consists of a data processing module, a data storage module, a driving module, a current transducer, a signal converter, a filter module, an AC power supply monitoring module, a DC power supply monitoring module, a UPS (Uninterruptible Power Supply) monitoring module, a circuit insulation monitoring module, a double-line switch monitoring module, a communication power supply detection module, a wireless communication module, an alarm module, a GPS (Global Positioning System) satellite signal positioning module, an I / O (Input / Output) module and a display, wherein a communication module is formed in a way that the wireless communication module and a wired communication module are connected in parallel, and the alarm module is formed in a way that an alarm and an emergency stop switch are connected in series. According to the master monitoring device of the AC / DC integration power supply disclosed by the invention, uninterrupted collection and storage can be effectively carried out on each main power supply of a transformer substation, alarm can be carried out on an abnormal point or fault, accurate positioning is only carried out on fault power transformation, meanwhile, data and control communication can be carried out through a wireless or wired transmission way, and thus the integration degree and the automation degree of control management of the transformer substation can be enhanced.

Description

technical field [0001] The invention relates to a total monitoring device for an integrated AC and DC power supply, which belongs to the technical field of power transmission and transformation equipment. Background technique [0002] The substation is an important part of the power transmission and transformation system. The operation stability and work efficiency of the substation are directly related to the operation quality and efficiency of the entire power supply network, which has a major impact on the national economy and people's livelihood. Generally, it includes four main power supply systems including station DC power supply, station AC power supply, UPS power supply, station communication power supply and an auxiliary line switching power supply system. In order to improve the stability of substation operation, these power supply systems are usually designed as Independent working system, there is no relationship between each system, but this design also leads t...

[0002] The substation is an important part of the power transmission and transformation system. The operation stability and work efficiency of the substation are directly related to the operation quality and efficiency of the entire power supply network, which has a major impact on the national economy and people's livelihood. Generally, it includes four main power supply systems including station DC power supply, station AC power supply, UPS power supply, station communication power supply and an auxiliary line switching power supply system. In order to improve the stability of substation operation, these power supply systems are usually designed as Independent working system, there is no relationship between each system, but this design also leads to the lack of effective and unified supervision and maintenance among the various systems, resulting in the lack of timely information on the operating parameters, operating status, and hidden troubles of the substation. Information feedback, which on the one hand leads to confusion in the supervision of substations, and on the other hand reduces the automation of substation operations, which cannot meet the needs of power supply system development
