A method for recording and replaying the implementation process of secondary safety measures in smart substations

Abstract

The invention discloses a method for recording and replaying the implementation process of secondary security measures in intelligent substations, extracting IED data sets; creating a library of security measures for IED equipment in intelligent substations; Device panel indicator light entry; select an IED device security measure entry set for initial status verification and start implementation; record the status change report of the received IED device security measure entry; make a playback file and play it back. The invention is convenient for tracking traces of implementing safety measures afterwards, analyzing accident causes, and improving operation and maintenance efficiency.

Description

technical field [0001] The invention belongs to the field of operation, maintenance and repair of the secondary system of the smart substation in the smart grid. In particular, the invention relates to a method for recording and replaying the implementation process of a secondary safety measure in an intelligent substation. Background technique [0002] Traditional substations are equipped with more protection function hard pressure plates and protection export hard pressure plates. Smart substations have greatly reduced the number of hard pressure plates. , Soft platen method realized by intangible software. When the secondary equipment of the traditional substation is overhauled or rebuilt and expanded, there are safety work tickets or safety work cards for safety measures setting. Safety measure setting is an important process and technical means for overhauling, renovating and expanding equipment and personal safety guarantee. The implementation of secondary safety mea...

Problems solved by technology

[0003] Just because the observability and measurability of security measures in smart substations have deteriorated, the operating habits and ways of thinking have undergone major changes compared with traditional substations. Therefore, the correctness of the implementation of security measures has always been a relatively important task in the operation and maintenance work. Difficult problem. In some areas, large-scale power outages or even whole station power outages are used for maintenance, reconstruction and expansion, which seriously affects the continuity and reliability of power supply.
