BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 A flowchart of the auxiliary method for troubleshooting;

[0033] Figure 2 This is a display diagram of the human-computer interaction interface. DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0035] like Figure 1 As shown, a fault handling auxiliary method includes the following steps:

[0036] Step 1, in response to obtaining a device fault diagnosis message, parsing the device fault diagnosis message to obtain device fault diagnosis information;

[0037] Step 2, in response to the workstation and the workstation login user's authority meeting the preset push condition, obtaining a fault record matching the equipment fault diagnosis information from the fault result table of the smart grid dispatching control system;

[0038] Step 3: Generate a fault brief, fault details, a wiring diagram of the plant to which the faulty equipment belongs, auxiliary decision-making for adjusting the power grid mode, auxiliary decision-making for fault trial transmission, and a fault report based on the equipment fault diagnosis information and fault records;

[0039] Step 4: Push the fault briefing, fault details, the wiring diagram of the plant to which the faulty equipment belongs, auxiliary decision-making for grid mode adjustment, auxiliary decision-making for fault trial transmission and fault report to the human-computer interaction interface for display to assist in fault handling.

[0040] In the implementation of the above method, the workstation receives the message sent by the server to push the fault handling interface. The method parses the acquired equipment fault diagnosis message, and obtains the fault record matching the equipment fault diagnosis information from the fault result table when the workstation and user authority meet the push conditions. The method generates and sends to the human-computer interaction interface a fault briefing, fault detailed information, the wiring diagram of the plant to which the faulty equipment belongs, auxiliary decision-making for power grid mode adjustment, and auxiliary decision-making for fault trial transmission, so as to provide strong support for power grid fault handling, improve fault handling efficiency, and ensure safe and stable operation of the power grid and power supply reliability.

[0041] The equipment fault diagnosis message is a message published by the fault event publishing channel (channel number 36, configurable). The equipment fault diagnosis message is monitored online through the message bus interface of the smart grid dispatching control system. The message can be obtained periodically. The cycle time can be configured according to the situation, generally 1 second.

[0042] After obtaining the fault diagnosis message, parse the message content to obtain equipment fault diagnosis information such as fault time, fault device, fault phase, coincidence condition during line fault (only for line fault) and fault distance measurement during line fault (only for line fault).

[0043] After parsing the equipment fault diagnosis information, the node name of the workstation is obtained, and at the same time, the user name, work group, permissions, etc. of the node login user are obtained through the permission management interface provided by the smart grid dispatching and control system.

[0044] The workstation is used to push information to the human-computer interaction interface. Different users (i.e., the control personnel of the control center) can log in. The control personnel can choose whether the workstation they use needs to push information according to their own work needs. Different control personnel have different needs for the range of equipment, which is specifically reflected in the configuration of permissions and user groups, which can meet a customized push.

[0045] When the permissions of the workstation and the user logged in to the workstation meet the preset push conditions, that is, the workstation is configured to push images and the node login user has push permissions, it means that information can be pushed to the human-computer interaction interface, and fault records matching the equipment fault diagnosis information are obtained from the fault result table of the smart grid dispatching and control system. Based on the equipment fault diagnosis information and fault records, the information to be pushed is generated.

[0046] The alarm human-machine interface can collect fault diagnosis results and key information on power grid operation, auxiliary decision-making for power grid mode adjustment and auxiliary decision-making for fault trial transmission, etc., to support the fault perception and fault handling business of dispatching and operation personnel.

[0047] like Figure 2 The contents collected in the present invention specifically include fault briefings, fault detailed information, plant wiring diagrams of the faulty equipment, auxiliary decision-making for grid mode adjustment, auxiliary decision-making for fault trial transmission and fault reports generated based on equipment fault diagnosis information and fault records.

[0048] The fault brief is a brief report composed of equipment fault diagnosis information in text form, mainly including the parsed fault time, faulty equipment, fault phase, coincidence situation during line fault (only for line fault) and fault distance measurement during line fault (only for line fault), etc.; among them, the fault time description format is "yyyy / dd / mm hh:mm:ss", the name of the faulty equipment is described by the name in the equipment table in the smart grid dispatching and control system, the fault phase is displayed in the form of "Phase A, Phase B, Phase C", etc., the coincidence situation is displayed in the form of "Reclosing success, Reclosing failure", etc., and the fault distance measurement is in "km", showing the distance between the fault point and the fault head and end station.

[0049] The process of generating fault detailed information includes: matching relevant switch information, protection information, three-span information, meteorological information, PMU information and recording information according to the fault record, and taking the switch information, protection information, three-span information, meteorological information, PMU information and recording information as fault detailed information.

[0050] The human-machine interface can provide switch information buttons, protection information buttons, three-span information buttons, recording information buttons, PMU information buttons, and meteorological information buttons. Detailed fault information can be viewed through the buttons. The switch information displays the action time, switch name, switch status, signal type, etc. The protection information displays the action time, protection name, signal level, signal type, etc. The three-span information displays the line name, cross-span type, spanned facility name, spanning tower number, spanning longitude and latitude, etc. The recording information displays the fault recording curve, including three-phase current, three-phase voltage, related switch quantities, etc. The PMU information displays the PMU curve, including three-phase current / power angle, three-phase voltage / power angle. The meteorological information displays temperature, relative humidity, wind speed, wind direction, air pressure, precipitation, etc.

[0051] The fault report is an accident report in a specific format that comprehensively generates a fault brief, fault detailed information, the wiring diagram of the plant to which the faulty equipment belongs, auxiliary decisions for grid mode adjustment and auxiliary decisions for fault trial transmission; it may include fault time, faulty equipment, switch action information corresponding to the fault, protection action information corresponding to the fault, auxiliary decisions for grid mode adjustment and auxiliary decisions for fault trial transmission, etc. The accident report can be edited manually, and the edited text can be exported in WORD format through the export button for easy reference and retention.

[0052] The process of generating the plant station wiring diagram to which the equipment belongs includes: obtaining the plant station to which the faulty equipment belongs according to the plant station, and obtaining the primary wiring diagram of the plant station according to the plant station.

[0053] The plant wiring diagram in g format can be directly embedded in the human-computer interaction interface, and the displayed content includes the plant name, the connection relationship of the plant primary equipment, and the corresponding measurement information of each interval of the plant; among them, the primary equipment includes busbars, transformers, lines, circuit breakers, switches, etc., and the measurement information includes current, voltage, power, main transformer gear position / temperature, etc.

[0054] The process of generating auxiliary decision-making for grid mode adjustment includes: obtaining information on section control limits after a fault, grid operation mode adjustment requirements, voltage control requirements and DC adjustment requirements; generating auxiliary decision-making for grid mode adjustment based on the information on section control limits after a fault, grid operation mode adjustment requirements, voltage control requirements and DC adjustment requirements, and specifically distinguishing between planned maintenance work in the vicinity of the fault and unplanned maintenance work in the vicinity of the fault.

[0055] Planned maintenance work in the fault vicinity: If the fault that occurs is the fault anticipated in the anti-accident plan formulated before the planned maintenance, the automatically generated auxiliary decision for adjusting the power grid mode will directly call up the corresponding anti-accident plan; if the fault that occurs is not the fault anticipated in the anti-accident plan formulated before the planned maintenance, the N-2 control principle corresponding to the fault will be obtained, and after manual confirmation, the auxiliary decision for adjusting the power grid mode will be automatically generated.

[0056] Unplanned maintenance work in the fault vicinity: If the fault occurs within the scope of the grid stable operation regulations, the information such as section control limit, grid operation mode adjustment requirements, voltage control requirements, and DC adjustment requirements after the fault will be automatically obtained. If the fault does not occur within the scope of the grid stable operation regulations, the N-1 control principle corresponding to the fault will be automatically generated after manual confirmation to assist in the grid mode adjustment decision.

[0057] The process of generating auxiliary decision for fault trial transmission includes: obtaining relevant content of faulty equipment from the detailed rules and regulations of power grid dispatching and control management; matching relevant protection information, meteorological information and recording information according to fault records; generating auxiliary decision for fault trial transmission according to relevant content of faulty equipment, protection information, meteorological information and recording information.

[0058] The above-generated information is pushed to the human-computer interaction interface for display to assist in fault handling. When pushed, the human-computer interaction interface pops up on top, and the human-computer interaction interface pops up in a fault identification mode. The fault identification is the identification of the fault information in the database of the smart grid dispatching and control system (keyword index). In this mode, the interface displays the fault information associated with the identification.
