Abstract

The invention relates to the technical field of intelligent substation state monitoring systems, in particular to an intelligent substation comprehensive monitoring unit. One end of the intelligent substation comprehensive monitoring unit is connected with a monitoring device through an I0 interface based on a MODBUS protocol to perform communication and acquire state monitoring data. The other end of the intelligent substation comprehensive monitoring unit is connected with a station level device station-side monitoring unit through a power transformation I1interface based on IEC61850 and finishes uploading of the state monitoring data. The intelligent substation comprehensive monitoring system can solve the problem that data models, communication modes and communication protocols of a state monitoring system are excessively privatized for a long time and sharing and unification processing is difficult, provides a normalized solution and an implementation scheme for follow-up development of an intelligent substation online monitoring system, provides strong support for primary device state visualization and condition based maintenance of electrical equipment and has important significance on avoiding of electrical equipment accidents and guarantee of safe, reliable and normal operation of the equipment.

Description

technical field [0001] The invention relates to the technical field of an intelligent substation state monitoring system, in particular to an intelligent substation comprehensive monitoring unit. Background technique [0002] In terms of smart grid construction, the State Grid Corporation of China has put forward the development goal of building a unified and strong smart grid with the characteristics of informatization, automation, and interaction based on independent innovation, with the UHV grid as the backbone grid, and the coordinated development of grids at all levels. According to the requirements of State Grid Corporation of China's "Technical Guidelines for Smart Substations" and "Code for Design of Smart Substations", it is necessary to realize the status visualization of primary equipment. This requires the installation of an online monitoring system in the smart substation, through the online monitoring system to obtain various status information of the primary e...
