Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, and the contents of the specific embodiments are not intended to limit the scope of protection of the present invention.

[0016] The invention relates to a method for analyzing protection action information based on fault recording. The method obtains data from fault recording, provides a new means and method for analysis of protection actions in power grids, and provides a basis for judging protection action behavior after an accident. References are provided.

[0017] figure 1 A flow chart of the protection action information analysis method based on the fault recording is shown in the present invention. Such as figure 1 As shown, the protection action information analysis method based on fault recording in the present invention first establishes a configuration model, that is, based on the primary equipment, establishes the configuration a...

Abstract

The invention relates to a fault-recording-based protection action information analyzing method. The fault-recording-based protection action information analyzing method comprises the steps that a configuration model is built; primary equipment serves as the basis, and a configuration model of association among the primary equipment, secondary equipment related to the primary equipment and a protection device is built; the protection action behavior state and sequential relationship of the protection device of the primary equipment and the secondary equipment related to the primary equipment are determined, and the protection action behavior state of the protection device is described with time as the axis; on the basis of the protection action behavior state and sequential relationship of the protection device of the primary equipment and the secondary equipment related to the primary equipment, in combination with protection action behavior logic and related constant-value information in the actual process, the protection action behavior of the protection device is judged, and inverting is performed on the fault process; the result is comprehensively analyzed, and a protection action report is formed. The method obtains data from fault recording, a new means and a new method are provided for protection action analysis in a power grid, and a reference base is provided for protection action behavior judgment after an accident.

Description

technical field [0001] The invention belongs to the technical field of power grid fault monitoring, and relates to a method for analyzing protection action information of a protection device, in particular to a method for analyzing protection action information based on fault recording. Background technique [0002] After a fault occurs in the power grid, it is often necessary to analyze the protection action behavior of the protection devices of the primary equipment and secondary equipment in the power grid to determine the fault location; at the same time, it is also convenient to find out the cause of the fault; and it is helpful to prevent the same fault happened again. However, most of the existing protective action behavior analysis methods of protective devices start from the protective device itself, find out the fault of the protective device, and replace the protective device. Therefore, it is difficult to conduct an effective analysis on the protection action of...
