Description

Technical Field

[0001] The present invention relates to the technical field of power grid monitoring, and in particular to a method and device for shielding alarm signals of secondary equipment. Background Art

[0002] When the power dispatcher is carrying out power grid monitoring business, if the power equipment is transferred to the on-site operation personnel for signal monitoring due to planned work or temporary fault elimination on site, the power dispatcher can hang an electronic signboard on the equipment in the operation monitoring system to shield the relevant signals of the equipment, so that the relevant signals will not appear in the signal alarm window of the operation monitoring system, thereby reducing interference with the monitoring business. When resuming dispatch monitoring, the relevant signal shielding can be lifted by simply removing the electronic signboard.

[0003] However, this method is currently only applied to primary equipment.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

[0047] For example 1, please refer to Figure 1 , Figure 1 This is a flowchart of a first embodiment of a method for shielding an alarm signal of a secondary device of the present invention, including:

[0048] Step S101: obtaining secondary equipment alarm information from the master station dispatch automation system and determining an information mapping relationship corresponding to the secondary equipment alarm information;

[0052] Step S105 , based on the real-time status of the primitive module, determining whether the secondary device alarm information associated with the topology mapping relationship is output to the dispatcher monitoring alarm window of the operation monitoring system.

[0053] A method for shielding alarm signals of secondary equipment provided in an embodiment of the present invention includes: obtaining secondary equipment alarm information from a master station dispatch automation system, determining an information mapping relationship corresponding to the secondary equipment alarm information; determining a secondary equipment abnormal information alarm point table based on the information mapping relationship; dividing the obtained primary equipment intervals, determining key secondary equipment, and establishing a graphic element module for the key secondary equipment; establishing a topological mapping relationship corresponding to each graphic element module and the existing abnormal signals in the secondary equipment abnormal information alarm point table; and determining whether the secondary equipment alarm information associated with the topological mapping relationship is output to the dispatcher monitoring alarm window of the operation monitoring system based on the real-time status of the graphic element module. By constructing a graphic element module for key secondary equipment and establishing an association between the corresponding secondary equipment alarm information and the graphic element module, batch shielding and contact shielding of signals can be achieved by listing and delisting operations on the secondary equipment graphic element, thereby avoiding interference of secondary equipment alarm signals with monitoring services, thereby improving monitoring service efficiency and safety levels.

[0054] For example 2, please refer to Figure 2 , Figure 2 This is a flowchart of a second embodiment of a method for shielding an alarm signal of a secondary device of the present invention, the method comprising:

[0055] Step S201: obtaining secondary equipment alarm information from the master station dispatch automation system and determining an information mapping relationship corresponding to the secondary equipment alarm information;

[0056] It should be noted that secondary equipment refers to low-voltage electrical equipment required to monitor, control, adjust, and protect the operation of primary equipment, as well as to provide operating conditions or production command signals to operation and maintenance personnel. According to the operating status of the primary equipment and system, when it is judged that a fault or abnormality has occurred, a tripping command is automatically issued to selectively cut off the fault and a corresponding signal is sent. When the fault or abnormality disappears, the relevant circuit breakers are quickly put into operation to restore the normal operation of the system.

[0057] In the embodiment of the present invention, the substation secondary equipment alarm information in the master station dispatching automation system is transmitted by the station-side intelligent telemachine.

[0058] Step S202: determining the alarm level corresponding to each secondary device alarm information according to a preset alarm level evaluation standard;

[0059] In the embodiment of the present invention, the preset alarm level evaluation standard is the alarm level evaluation standard in the expert method.

[0060] Step S203: obtaining the secondary equipment abnormality information alarm point table based on the alarm level and in combination with the information mapping relationship;

[0061] In the embodiment of the present invention, a corresponding abnormal alarm information mapping relationship is established in the master station automation system, and a secondary equipment abnormal information alarm point table is formed according to the alarm level corresponding to the secondary equipment alarm information defined by the expert rule.

[0062] Step S204, dividing the obtained primary equipment intervals, determining key secondary equipment, and establishing a graphic primitive module of the key secondary equipment;

[0063] Step S205: establishing a topological mapping relationship between each of the graphic primitive modules and the stored abnormal signals in the secondary equipment abnormal information alarm point table;

[0064] In an embodiment of the present invention, correlation division is performed according to the interval of primary equipment to obtain key secondary equipment with more correlations. Then, a graphic element module of each key secondary equipment is established in the operation control system (OCS). By performing topological analysis on the alarm signals of the secondary equipment, a topological mapping relationship is established between each graphic element module and the existing abnormal signals of the abnormal information alarm point table of the secondary equipment in the OCS system.

[0065] It should be noted that the OCS system refers to the application system within the master / substation system that implements real-time grid operation monitoring and control functions. Secondary equipment elements are divided according to the associations of primary equipment intervals, with each key secondary device having a separate element within the system.

[0066] Step S206, obtaining the real-time status of the target primitive module associated with the topological mapping relationship;

[0067] Step S207: determining whether the associated secondary device alarm information is output to the dispatcher monitoring alarm window based on the real-time status and in combination with the topology mapping relationship;

[0068] In the embodiment of the present invention, according to the working principle of secondary equipment, the alarm information of the associated secondary equipment in the OCS system is merged and analyzed, and the alarm signal is output according to the topological mapping relationship established by the primitive module and the real-time status.

[0069] In an optional embodiment, the real-time status includes: an activation status and an exit status; and determining, based on the real-time status and in combination with the topology mapping relationship, whether the associated secondary device alarm information is output to the dispatcher monitoring alarm window of the operation monitoring system includes:

[0070] If the real-time status is the input status, the associated secondary equipment alarm information is output to the dispatcher monitoring alarm window;

[0071] If the current secondary equipment element is in the exit state, the associated secondary equipment alarm information will be shielded.

[0072] It should be noted that the "on" state refers to the normal operation of the device, with all functions and outlet pressure plates being normally operated; the "off" state refers to the exit of all functions or outlets of the device.

[0073] In an embodiment of the present invention, according to actual work needs, the operation of putting the secondary equipment in and out of service is determined and its real-time status is defined in the corresponding secondary equipment element in the OCS system. Each secondary equipment element has two status settings: "in service" or "out service". Then, according to the real-time status of the secondary equipment element in the OCS system, it is determined whether the associated abnormal alarm information is output to the OCS system dispatcher monitoring alarm window. If the current secondary equipment element is in the "in service" state, the alarm abnormality signal associated with the element is normally uploaded to the OCS system alarm window; if the current secondary equipment element is in the "out service" state, the alarm abnormality signal associated with the element is automatically shielded and not uploaded to the OCS system alarm window, but the relevant alarm information can be checked.

[0074] A method for shielding alarm signals of secondary equipment provided in an embodiment of the present invention includes: obtaining secondary equipment alarm information from a master station dispatch automation system, determining an information mapping relationship corresponding to the secondary equipment alarm information; determining a secondary equipment abnormal information alarm point table based on the information mapping relationship; dividing the obtained primary equipment intervals, determining key secondary equipment, and establishing a graphic element module for the key secondary equipment; establishing a topological mapping relationship corresponding to each graphic element module and the existing abnormal signals in the secondary equipment abnormal information alarm point table; and determining whether the secondary equipment alarm information associated with the topological mapping relationship is output to the dispatcher monitoring alarm window of the operation monitoring system based on the real-time status of the graphic element module. By constructing a graphic element module for key secondary equipment and establishing an association between the corresponding secondary equipment alarm information and the graphic element module, batch shielding and contact shielding of signals can be achieved by listing and delisting operations on the secondary equipment graphic element, thereby avoiding interference of secondary equipment alarm signals with monitoring services, thereby improving monitoring service efficiency and safety levels.
