Abstract

The invention relates to the technical field of substations and discloses a monitoring system and a method of the operation condition of a digitalized substation secondary device. The system comprises a plurality of digitalized substation secondary devices and station level devices, wherein the secondary devices are directly or indirectly connected with the station level devices through respective network message recording device. The system also comprises a condition monitoring device and a plurality of network analysers corresponding to the network message recording devices, wherein the network analysers are respectively connected with the corresponding network message recording devices, and the condition monitoring device is respectively in communicating junction with each network analyzer and each station level device. In the invention, through additionally arranging the corresponding network analysers and the condition monitoring devices in the existing comprehensive automation communication network of a digitalized substation, the requirements of monitoring the condition of the digitalized substation can be fully satisfied so as to provide related data support for the condition repairing system and life time cycle cost management of the digitalized substation built on the basis of the invention and other advanced applications.

Description

technical field

[0001] The invention relates to the technical field of substations, in particular to a monitoring system and method for the operation status of secondary equipment in digital substations. Background technique

[0002] As digital substations go from theory to reality, newly established digital substations are already under construction and put into use. The operating status of secondary equipment and network equipment such as protection\measurement and control devices, network message recording equipment, communication networks, and protection substations will directly affect the operation safety of the entire digital substation. Because the data and information of the remote control terminal and the remote control host are exchanged on the digital substation comprehensive automation data network through the IEC61850 protocol, the system such as figure 1 As shown, all the information for condition monitoring of secondary equipment and network equipment can be...
