Description
Technical Field
The utility model relates to an electric power system technical field specifically is network monitoring analysis record appearance.
Background
With the development of an electric power system and the increase of power consumption requirements, the number of transformer substations is increased rapidly, a county regulation and control integrated technology is popularized rapidly and comprehensively in a network, transformer substations of 35kV and above governed by a six-coil water power grid have unattended technical conditions, a network communication technology between a regulation and control main station and a transformer substation station becomes a key factor of intelligent power grid development, and improvement of comprehensive detection and network analysis of a telecontrol device is particularly important.
At present, the research and development, design, test and application technologies of a telecontrol system of a domestic mainstream manufacturer are mature and perfect, the data communication between a regulation and control main station and a transformer station end can be accurately completed, and the function of the telecontrol system in a regulation and control integrated system is well completed, but along with the development requirements of complicated network structure, diversified network levels and lean network management in an electric power system, the comprehensive detection and network analysis of a telecontrol device per se also have the following defects and shortcomings:
