Transformer substation intelligent relay protection concentrated printing system

Abstract

A transformer substation intelligent relay protection concentrated printing system disclosed by the present invention comprises a protection device arranged at a transformer substation, a printing forwarding server used for forwarding the printing data, a network switch used for processing the network data, a constant value comparing module used for comparing the constant values in a constant value printing manner and a monitoring background used for receiving the printing data. The monitoring background inputs a constant value list and transmits the data to the constant value comparing module, and then the constant value comparing module compares the monitored printing data and the data on the constant value list and then transmits to the monitoring background. The transformer substationintelligent relay protection concentrated printing system of the present invention solves the problem that the protection device is adapted from the local printing to the remote background printing, real-timely monitors the forwarded data, prints into a paper file automatically after receiving completely, and is convenient to check and back up. Moreover, the arranged constant value comparing module can compare the constant values in the constant value printing manner, an online constant value and a reference constant value can be compared automatically, and when the constant values have the difference, the difference can be displayed observably with different colors.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a centralized printing system for substation intelligent relay protection. Background technique [0002] Substations are developing towards automation. Unattended operation brings a lot of convenience to the management of substations, and the types of faults can be known without the need for maintenance personnel to go to the scene. However, there are still some relatively old-fashioned equipment in the substation, which cannot transmit fault information to the monitoring background in real time, resulting in faults, and maintenance personnel need to go to the scene to retrieve fault information and eliminate them, and the existing system can only centralize the information It shows that the maintenance personnel need to compare with the fixed value list later to know the fault information. Such a comparison process is very slow and inefficient. [0003] Therefo...
