Embodiment Construction

[0018] The invention discloses a method for recording fault recording data, which is suitable for storing fault recording data in small embedded devices in power systems. Such as figure 1 As shown, the above method includes the following steps:

[0019] Step S110: Obtain the wave recording data obtained by sampling and the data information of the wave recording data. Taking the fault recording triggered when the power system detects a fault as an example, the recording data obtained by sampling the fault recording of the power system is obtained in real time, and the data information of the recording data is extracted. In this embodiment, the data information may specifically include the entry address of the wave recording data in the dynamic storage interval, the total size of the data, the number of single channel points, the file header and status of the data information, etc., for subsequent data storage operations.

[0020] Step S120: During the interruption of fault re...

Abstract

The invention relates to a recording method and system of fault recording data. The recording method includes the steps: acquiring recording data obtained through sampling and the data information of the recording data; during the process for interruption of sampling of fault recording, according to the data information and the preset recording setting parameters, storing the corresponding recording data in a dynamic storage interval; and in the mode for delaying tasks, storing the recording data in the dynamic storage interval in a static storage zone. As the real time data is stored during the process for interruption of sampling and the original data is transferred from a designated recording file to a static memory by delaying the tasks, the recording method and system of fault recording data can guarantee the real-time for data storage and can avoid that file storage time occupies the resource of the main task of the system, and can realize real-time recording of the fault recording data under smaller software and hardware resource so that the applicability is improved.

Description

technical field [0001] The invention relates to the technical field of fault recording, in particular to a method and system for recording fault recording data. Background technique [0002] Fault recording means that when a fault occurs in the power system, it can automatically and accurately record the changes of various electrical quantities in the process before and after the fault of the power system. Whether the protection operates correctly and improves the safe operation level of the power system. [0003] Traditional power system embedded devices record power fault recording data, usually need to configure large-capacity dynamic and static storage devices, and the device uses a special data management plug-in to organize and record the recording data; due to the large amount of data, the recording Data storage occupies a large proportion of processor resources, and requires a lot of software and hardware resources to realize data storage, which has the disadvantage...
