Protection setting and key safety measures checking method based on 61850 client

Abstract

The invention discloses a protection setting and key safety measures checking method based on a 61850 client, which sequentially carries out the following steps: comparing three EXCEL format setting sheets to check whether the setting and the soft pressure plate in the three setting sheets are consistent; monitoring the overhaul state of the protection device to be overhauled and monitoring the alarm signal of GOOSE overhaul inconsistency of the protection device to be overhauled, and realizing the recognition of the overhaul state of the protection device to be overhauled and its related devices through the monitored state quantity; reading the overhaul status of the protection device to be overhauled in real time, the soft platen state and the GOOSE link communication state, to realizethe alarm function of whether the secondary security measures are missing, The protection setting and key safety measures checking method based on 61850 client is provided. When it is applied, it canmake the setting of protection device, check of soft pressure plate fully automatic, and real-time monitor and alarm some key safety measures which may lead to power network safety accidents in the process of maintenance.

Description

technical field [0001] The invention relates to the technical field of maintenance of protection devices in intelligent substations, in particular to a method for checking protection values ​​and key safety measures based on a 61850 client. Background technique [0002] At present, maintenance personnel often need to change the fixed value and soft pressure plate of the protective device for the maintenance and elimination of the protection device of the smart substation. After the maintenance and elimination work, the fixed value and the soft pressure plate need to be restored to the state before the modification. Then the fixed value and soft pressure plate after the overhaul of the protection device (the fixed values ​​have been restored at this time) and the actual operation of the protection device before the overhaul, and whether the fixed value and soft pressure plate in the dispatched value sheet Consistent, maintenance personnel, operation and maintenance personnel ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned problems, the purpose of the present invention is to improve the above-mentioned inconveniences and deficiencies that exist when the protection device of the intelligent substation is overhauled and eliminated, and provide a method for checking the protection value and key safety measures based on the 61850 client, which can make the value of the protection device , The check of the soft pressure plate is fully automated, and some key safety measures that may lead to grid safety accidents are monitored and alarmed in real time during the maintenance process
