Embodiment 1

[0033] figure 1 It shows the implementation flow of the diagnosis method for the operation of secondary equipment maintenance safety measures provided by an embodiment of the present invention, and the process is described in detail as follows:

[0034] In step S101, the SCD total station system configuration file and the maintenance equipment selected by the user are obtained.

[0035] In this embodiment, the SCD (Substation Configuration Description) total station system configuration file of the smart substation is acquired.

[0036] In this embodiment, when the user needs to perform secondary equipment maintenance, select a number of equipment that needs to be overhauled, and select a protection device from the number of protection devices that need to be overhauled as the maintenance equipment.

[0037] In step S102, the secondary equipment associated with the maintenance equipment is determined according to the SCD total station system configuration file, and a protecti...

Embodiment 2

[0124] Such as Figure 4 As shown, an embodiment of the present invention provides a diagnostic system 100 for the operation of secondary equipment maintenance safety measures, which is used to perform figure 1 The method step in the corresponding embodiment, it comprises:

[0125] The information obtaining module 110 is used to obtain the SCD total station system configuration file and the maintenance equipment selected by the user.

[0126] The protection system generating module 120 is configured to determine the secondary equipment associated with the maintenance equipment according to the configuration file of the SCD total station system, and form a protection system. The protection system includes the maintenance equipment and the associated secondary equipment.

[0127] The state tree generating module 130 is configured to generate a state tree of the protection system, the state tree includes the basic nodes corresponding to each device in the protection system and t...

Embodiment 3

[0144] Image 6 It is a schematic diagram of a terminal device provided by an embodiment of the present invention. Such as Image 6 As shown, the terminal device 6 of this embodiment includes: a processor 60 , a memory 61 , and a computer program 62 stored in the memory 61 and operable on the processor 60 . When the processor 60 executes the computer program 62, the steps of each embodiment as described in Embodiment 1 are realized, for example figure 1 Steps S101 to S106 are shown. Alternatively, when the processor 60 executes the computer program 62, it realizes the functions of each module / unit in each system embodiment as described in Embodiment 2, for example Figure 4 The functions of the modules 110 to 160 are shown.

[0145] Exemplarily, the computer program 62 can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 61 and executed by the processor 60 to complete this invention. The one or more modules / units may b...

Abstract

The invention is applicable to the technical field of intelligent substation, A method and system for diagnosing the operation of safety measures for overhauling secondary equipment and Terminal Equipment are provided, The method comprises: Obtaining SCD total station system configuration files and user-selected overhaul equipment, determining the secondary equipment associated with the overhaul equipment according to the SCD total station system configuration file, and forming a protective system, Generating a state tree for the protection system, determining the actual results and the predicted results of the whole state according tothe basic nodes in the state tree, wherein the actual result of the overall state is associated with the operation of the safety measures for the maintenanceof the secondary equipment, If the actual result of the whole state matches with the corresponding prediction result, calibrating that the safety measures for the secondary equipment overhaul are operated correctly; if the actual result of the whole state does not match with the corresponding prediction result, calibrating that the safety measures for the secondary equipment overhaul are operatedincorrectly, which improves the accuracy of the operation diagnosis for the safety measures for the secondary equipment overhaul.

Description

technical field [0001] The invention belongs to the technical field of intelligent substations, and in particular relates to a diagnosis method, system and terminal equipment for the operation of safety measures for secondary equipment maintenance. Background technique [0002] With the current large-scale construction and operation of smart substations, as the focus of the integration of "power flow, information flow, and business flow" in smart grids, smart substations have become an important part of the power grid. It is extremely important for building a strong smart grid. effect. At present, the implementation process of safety measures for protection equipment in most smart substations is still that the maintenance personnel refer to the relevant procedures and specifications for maintenance operations, and the relevant staff follow the steps of the secondary equipment maintenance safety measures to carry out step by step. In this mode of operation, the accuracy of i...
