Alternating current-direct current integrated power monitoring device used for station

Abstract

The invention relates to an alternating current-direct current integrated power monitoring device used for a station, relates to electric power monitoring, and especially belongs to the technical filed of alternating current-direct current monitoring for a station. The alternating current-direct current integrated power monitoring device comprises a CPU (central processing unit) control circuit, a man-machine interface, a data storage circuit, an alarm interface circuit and a communication interface circuit, wherein the CPU control circuit is respectively connected with the man-machine interface, the data storage circuit and the communication interface circuit through signals, and the alarm interface circuit is connected to one output end of the CPU control circuit. The alternating current-direct current integrated power monitoring device provided by the invention can carry out centralized monitoring management on equipment such as an alternating current power supply system, a direct current power supply system, an inversion power system, a communication power supply system in the station and also can carry out centralization management on the data of all equipment; and an IEC (integrated ethernet chip) 61850 protocol is adopted to carry out communication with an upper computer system through an Ethernet interface, and a transformer substation / distribution substation power system becomes an open system.

Description

technical field [0001] The invention relates to electric power monitoring, in particular to the technical field of AC and DC monitoring for stations. Background technique [0002] The power monitoring devices of the traditional power system are limited to on-line monitoring of battery packs, insulation on-line monitoring, and charging modules, etc., and lack of data collection and unified management of AC power systems, inverter power systems, and communication power systems. In addition, each power supply system in the station is relatively independent at present, and they are all provided by different suppliers. The communication protocols are generally incompatible, which directly leads to a low degree of automation of the power supply, unable to achieve unified management, and poor reliability of the system. Contents of the invention [0003] The purpose of the present invention is to provide an integrated power monitoring device for various power systems in a station ...

Problems solved by technology

[0002] Traditional power system monitoring devices are limited to on-line monitoring of battery packs, insulation on-line monitoring, and charging modules, and lack data collection and unified management of AC power systems, inverter power systems, and communication power systems.

In addition, each power supply system in the station is relatively independent at present, and they are all provided by different suppliers. The communication protocols are generally incompatible, which directly leads to a low degree of automation of the power supply, which cannot achieve unified management, and the reliability of the system is poor.
