Power quality monitoring system based on International Electrotechnical Commission (IEC) 61850 communication protocol

Abstract

The invention provides a power quality monitoring system based on the International Electrotechnical Commission (IEC) 61850 communication protocol. The system comprises a web module, a communication module and a verifying module. The web module is used for transmitting request command to the communication module, timely obtaining data tasks and receiving and displaying power quality data from thecommunication module in graph and chart modes. Based on the IEC 61850 communication protocol, the communication module is used for being connected with a power quality monitoring device, transmittingstatistic data and real time data which are required by the power quality monitoring system and configuring configuration information of the power quality monitoring device. The verifying module is used for detecting and configuring the power quality monitoring device. Power quality monitoring devices of different manufacturers can be brought into the power quality monitoring system to achieve device diversity and improve adaptability of the power quality monitoring system. The communication module based on the IEC 61850 communication protocol resolves the problem of data transmission of a real time channel and can further transmit power quality data interchange format (PQDIF) files of statistic data to achieve comprehensive control of mass data.

Description

technical field [0001] The invention belongs to the field of power quality monitoring, and in particular relates to a power quality monitoring system based on the IEC61850 communication protocol. Background technique [0002] Power quality monitoring is an important link to improve the power quality level of the power grid. With the in-depth development of modern network technology, optical fiber communication technology and standardized protocols, and providing mature technical support for data collection, long-distance transmission and sharing, and timely analysis, the networked power quality monitoring system has become the mainstream of power quality monitoring Way. A number of online power quality monitoring and management platforms with unified monitoring have been established at home and abroad for data collection and statistical analysis, and FTP is generally used to transmit PQDIF data format files to solve communication problems in power quality monitoring systems...

AI Technical Summary

Problems solved by technology

However, so far, in the field of power quality system architecture, the IEC61850 communication standard has only been implemented in a certain type of module, and the data transmission problem of the real-time channel has not been solved from the perspective of a multi-platform and multi-language power quality monitoring system
