[0030] Embodiment 1

[0031] Figure 1 This is a flow chart of a substation equipment fault detection method provided by the first embodiment of the present invention. This embodiment is applicable to the case of fault detection of secondary equipment in a substation. The method can be executed by a substation equipment fault detection device. The substation equipment fault detection device can be implemented in the form of hardware and / or software. The substation equipment fault detection device can be configured in a terminal and / or a server. Figure 1 As shown, the method includes:

[0032] S110. In response to a fault detection request for the area to be tested, display a target interface; wherein the target interface includes an electrical circuit diagram corresponding to the area to be tested.

[0033] Among them, the area to be tested can be any area in the substation where fault detection is to be performed. Optionally, the area to be tested is an area in the substation divided according to preset rules. The preset rules may include any rules, and optionally, include division according to the functions performed by the power equipment, for example, the area to be tested includes the main wiring area, the distribution device area, the transformer area, the capacitor area, etc. The fault detection request can be understood as an instruction for requesting to perform the operation of equipment fault detection. The fault detection request may include multiple generation methods. Optionally, when a trigger operation for a preset fault detection control is detected, a fault detection request can be generated; or, when a trigger word associated with fault detection is detected in the received audio information, a fault detection request can be generated; or, when a fault detection trigger instruction input by a user is received, a fault detection request can be generated. The target interface can be understood as a visual interface presented to the user end for receiving interface interaction operations and presenting the status of secondary equipment. The target interface may include an electrical circuit diagram corresponding to the area to be tested. The electrical circuit diagram corresponds to the secondary equipment circuit corresponding to the area to be tested. In other words, the electrical circuit diagram is drawn based on the secondary equipment circuit corresponding to the area to be tested. The electrical circuit diagram may include multiple secondary devices and the connection relationship between each secondary device. The secondary device circuit can be understood as a secondary device connected to each other according to the corresponding electrical logic relationship to form an electrical circuit for detecting, controlling, adjusting and protecting the corresponding equipment. The electrical circuit diagram is at least used to indicate the electrical connection relationship between multiple secondary devices included in the area to be tested. The electrical circuit diagram can be understood as a circuit diagram used to display the secondary devices in the area to be tested and their mutual connection relationship. The device elements in the electrical circuit diagram may include relay elements, coil elements, isolating switch elements, transfer switch elements, auxiliary node elements, resistor elements, capacitor elements, inductor elements, optocoupler elements and diode elements, etc. These device elements are connected by wires or connecting lines to form a complex circuit network. For example, Figure 2 1 is a schematic diagram of an effect of an electrical circuit diagram provided according to an embodiment of the present invention. Figure 2 As shown, the electrical circuit diagram includes interfaces 1ZD.1, 1ZD.2, 1QD.1, 1ZD.11, 2D.1, 2D.2, 2D.7, 2D.6, 3D.6, 4D.6, 4D.16, 4D.17 and 1ZD.6; circuit breaker 1, K1 relay, K1 node 1, K2 node 2 and pressure plate switch 1.

[0034] In this embodiment, there are multiple ways to obtain the electrical circuit diagram. Optionally, a pre-generated electrical circuit diagram is retrieved from an electrical parameter database corresponding to the area to be tested; or, upon receiving a fault detection request for the area to be tested, an electrical circuit diagram is generated based on an electrical circuit model file corresponding to the area to be tested, etc.

[0035] As an optional implementation of this embodiment, when a trigger operation for a preset fault detection control associated with the area to be tested is detected, a fault detection request for the area to be tested can be generated. Further, in response to the fault detection request, a pre-generated electrical circuit diagram corresponding to the area to be tested is retrieved from an electrical parameter database corresponding to the area to be tested, and the retrieved electrical circuit diagram is displayed in the target interface.

[0036] In this embodiment, the electrical circuit diagram may be generated in a variety of ways, and optionally, may be generated based on a secondary circuit model file corresponding to the area to be tested.

[0037] Optionally, on the basis of the above-mentioned technical solutions, it also includes: obtaining a secondary circuit model file corresponding to the area to be tested, and parsing the secondary circuit model file to determine the device attribute information corresponding to multiple secondary devices included in the area to be tested and the interface connection relationship between the secondary devices; drawing and generating a secondary circuit diagram corresponding to the area to be tested according to the device attribute information and the interface connection relationship; performing electrical property conversion on the secondary circuit diagram to obtain an electrical circuit diagram corresponding to the area to be tested.

[0038] Among them, the secondary circuit model file is a file that describes the structure and connection relationship of the secondary circuit system of the substation. Optionally, the secondary circuit model file includes information about the panel cabinet and equipment, cables and connection relationships, circuit composition and functions, terminal blocks and wiring, etc. The secondary equipment can be a device that detects, controls, adjusts and protects the primary equipment in the substation. The secondary equipment can include signal devices, control devices, relay protection devices, automatic devices, instruments and operating power supplies, etc. The equipment attribute information can be understood as information that characterizes the basic attributes and electrical attributes of the secondary equipment. The equipment attribute information can include basic equipment attributes and equipment electrical attributes. Exemplarily, the basic attributes of the equipment include equipment name, equipment description, equipment type, equipment model, equipment version, etc. The electrical attributes of the equipment include rated voltage, rated current, excitation voltage, excitation current, impedance, etc. The interface connection relationship can be used to characterize the cable connection relationship between interfaces. The secondary circuit diagram is used to indicate the physical connection relationship between multiple secondary devices included in the area to be tested. The secondary circuit diagram can be a circuit diagram generated by visually representing the secondary circuit model file. In the secondary circuit diagram, the corresponding secondary equipment can be represented by specific graphic elements, and the graphic elements corresponding to the corresponding secondary equipment can be connected according to the interface connection relationship to obtain the secondary circuit diagram. It should be noted that the secondary circuit diagram does not include the electrical logic relationship between the secondary equipment. Therefore, the secondary circuit diagram can only be used to visualize the secondary equipment circuit in the substation, and cannot be operated to obtain the circuit operation information.

[0039] As an optional implementation of this embodiment, a secondary circuit model file corresponding to the area to be tested can be obtained. Further, the secondary circuit model file can be parsed to extract the device attribute information and interface connection relationship corresponding to each secondary device in the secondary circuit model file. Further, a graphical tool can be used to construct a full circuit based on the device attribute information and the interface connection relationship, and draw a secondary circuit diagram corresponding to the area to be tested. Further, the physical connection relationship in the secondary circuit diagram can be converted into an electrical connection relationship to perform electrical property conversion on the secondary circuit diagram, and the circuit diagram obtained after the conversion is used as an electrical circuit diagram.

[0040] Optionally, the electrical properties of the secondary circuit diagram are converted to obtain an electrical circuit diagram corresponding to the area to be tested, including: converting the device graphics included in the secondary circuit diagram into device components according to a preset graphics mapping relationship; obtaining the electrical property information and device name corresponding to the secondary equipment, and constructing an electrical logical relationship based on the electrical property information and the device name; and determining the electrical circuit diagram corresponding to the area to be tested based on each device component and the electrical logical relationship.

[0041] Among them, the primitive mapping relationship can be used to indicate the correspondence between the device primitive and the device element. The device primitive can be a graphic symbol used to characterize the secondary device. The device primitive can be composed of basic graphics such as points, lines, rectangles, circles, etc. These basic graphics can be combined into graphic symbols of various shapes. When the graphic symbol is given various attributes (such as display attributes such as color, line type, line width, position, size, and connection attributes such as the connection relationship between primitives), an actual usable device primitive is formed. The device element can be a graphical representation of the relevant secondary device. It can be understood that in the electrical circuit diagram, each electrical equipment element is represented by a specific graphic symbol, which is standardized and complies with international or domestic electrical graphic symbol standards. Electrical attribute information can be used to characterize a series of performance indicators of secondary equipment during operation. Exemplarily, the electrical property information corresponding to the electrical connection point and the electrical connection line is that the impedance is 0; the impedance of the relay element, coil element, resistor element, capacitor element, inductor element, and optocoupler element is determined according to the electrical property information included in the secondary circuit model file; the electrical property information corresponding to the isolating switch element, the transfer switch element, and the auxiliary node element is that they have the functions of opening, closing, and converting the connection, and can disconnect, close, and convert the electrical connection circuit; the electrical property information corresponding to the diode element is that it has the functions of voltage stabilization, current limiting, and directional conduction. The electrical logic relationship can be understood as the logical relationship between the various electrical components in the electrical circuit. The electrical logic relationship refers to the connection method of each electrical component, as well as their operating rules and logical relationships in the circuit. Optionally, the electrical logic relationship includes a series relationship, a parallel relationship, and a composite relationship.

[0042] As an optional implementation of this embodiment, when a secondary circuit diagram is obtained, the device graphic elements in the secondary circuit diagram can be converted into device components according to a preset graphic element mapping relationship. Further, the electrical property information and device names corresponding to the multiple secondary devices included in the area to be tested can be obtained, and the logical relationship between the secondary devices can be determined according to the electrical property information, and an association relationship can be established according to the electrical property information and the device name based on the logical relationship to obtain an electrical logical relationship that can be linked. Further, the secondary circuit diagram can be converted into an electrical circuit diagram according to the device components and the electrical logical relationship.

[0043] S120 , in response to the loop information acquisition operation inputted into the target interface, the loop information to be detected corresponding to the area to be detected is acquired, and target abnormal operating condition information corresponding to the area to be detected is determined according to the loop information to be detected.

[0044] Among them, the loop information acquisition operation can be understood as an operation of acquiring the electrical loop operation information corresponding to the area to be tested. The loop information acquisition operation may include any operation of inputting information representing the actual operation of the electrical loop into the corresponding fault detection system, optionally including loop information input operation and / or loop information retrieval operation, etc. The loop information to be detected may be loop operation information for the fault detection. The loop information to be detected is loop operation information obtained based on the actual operation of the secondary device loop corresponding to the area to be tested. The loop information to be detected can be used to characterize the actual operation information of the secondary device loop corresponding to the area to be tested. The loop information to be detected may include multiple pieces of information associated with the operation of the secondary device loop. Optionally, the loop information to be detected includes loop operation triggering conditions and loop operation results. The loop operation triggering conditions may be conditions for triggering the operation of the secondary device loop. Optionally, the loop operation triggering conditions include loop access to a voltage source or loop access to a current source, etc. The loop operation result may be used to characterize the state of the relevant secondary device when the secondary device loop is operating. The loop operation result may include at least one device parameter. Optionally, the device parameters include relay parameters, coil parameters, isolation switch parameters, transfer switch parameters, auxiliary node parameters, resistance parameters, capacitance parameters, inductance parameters, optocoupler parameters, and diode parameters. Figure 2 , assuming that from Figure 2 Connect the voltage source U1 between the interfaces 1ZD.1-1ZD.6 in the circuit, and then run Figure 2The result of the secondary device circuit corresponding to the electrical circuit diagram shown is that the relay K1 is not energized and the K1 node is not closed. Furthermore, the voltage source U1 can be connected between the interfaces 1ZD.1-1ZD.6 as a trigger condition for the circuit operation, and the relay K1 is not energized and the K1 node is not closed as the circuit operation result. The circuit operation result may include a normal circuit operation result and an abnormal circuit operation result. Generally, when an abnormal operation occurs in the area to be tested, it is necessary to perform equipment fault detection on the area to be tested. The circuit operation result input when performing equipment fault detection on the area to be tested is usually an abnormal circuit operation result. Furthermore, the circuit operation result included in the circuit information to be detected may be an abnormal circuit operation result. The target abnormal operating condition information may be used to characterize the corresponding operation abnormality details when the operation result of the secondary device circuit corresponding to the area to be tested is the circuit information to be detected. The target abnormal operating condition information may include multiple pieces of information that can characterize the operation abnormality details, optionally, at least including a faulty secondary device and / or the cause of the abnormal result. The faulty secondary device may be a secondary device that has a fault in the area to be tested. The cause of the abnormal result may be understood as the cause of the abnormal situation in the secondary device circuit. For example, continue to refer to Figure 2 , assuming that the target abnormal operating condition information is an internal fault of the K1 relay, the faulty secondary device is the K1 relay, and the abnormal cause is a fault inside the relay.

[0045] In this embodiment, there are multiple ways to obtain the circuit information to be detected according to the circuit information acquisition operation. The following are descriptions of these acquisition methods respectively:

[0046] The first type is that the target interface includes a loop information retrieval control; in response to a loop information acquisition operation input on the target interface, the loop information to be detected corresponding to the area to be tested is acquired, including: in response to a control trigger operation on the loop information retrieval control, a loop identifier corresponding to at least one candidate loop operation information is displayed; in response to a selection trigger operation on the loop identifier, the loop operation information corresponding to the selected loop identifier is used as the loop information to be detected corresponding to the area to be tested, and the loop information to be detected is retrieved from a database associated with the area to be tested.

[0047] Among them, the loop information retrieval control may be a control set in the target interface for triggering information retrieval. The loop operation information may be information characterizing the loop operation status obtained by setting the equipment parameters of the secondary equipment loop corresponding to the area to be tested, and running the secondary equipment loop after the setting is completed. The loop operation information may include loop operation results and equipment parameters required for loop operation, etc. Generally, after the operation of the secondary equipment loop corresponding to the area to be tested is completed, the loop operation information can be obtained, and the loop identification corresponding to the loop operation information can be determined. Furthermore, the loop operation information and its corresponding loop identification can be associated and stored in a database associated with the area to be tested. The loop identification may be information used to identify the loop operation information. Optionally, the loop identification is information based on numbers, text or other characters.

[0048] As an optional implementation of this embodiment, when a control trigger operation for a loop information retrieval control in the target interface is detected, a loop identifier corresponding to at least one candidate loop operation information can be displayed based on the stored loop operation information. Further, when a selection trigger operation for any loop identifier is detected, the loop operation data corresponding to the selected loop identifier can be used as the loop information to be detected corresponding to the area to be detected, and the loop information to be detected can be retrieved from a database associated with the area to be detected.

[0049] The second type is that the target interface includes a loop information setting item; in response to a loop information acquisition operation input on the target interface, the loop information to be detected corresponding to the area to be detected is obtained, including: in response to an information setting operation on the loop information setting item, the set loop operation information is determined according to the information setting operation; in response to a setting completion operation, the set loop operation information is obtained, and the obtained loop operation information is used as the loop information to be detected corresponding to the area to be detected.

[0050] Among them, the loop information setting item can be understood as the operation entry for setting various equipment parameters and loop operation results required for running the secondary device loop. That is, information associated with the operation of the secondary device loop can be input into the fault detection system based on the loop information setting item. The loop information setting item may include an operation trigger condition setting item and an operation result setting item. The operation trigger condition setting item can be used to set the trigger condition required for running the secondary device loop. The operation result setting item can be used to set the state of the relevant secondary device when the secondary device loop is running. Optionally, the operation result setting item may include a relay parameter setting item, a coil parameter setting item, an isolating switch parameter setting item, a transfer switch parameter setting item, an auxiliary node parameter setting item, a resistor parameter setting item, a capacitor parameter setting item, an inductor parameter setting item, an optocoupler parameter setting item, and a diode parameter setting item. The information setting operation can be understood as an operation for setting the loop operation information input into the fault detection system. The setting completion operation can be understood as an operation for characterizing that the loop information setting process has been completed. The setting completion operation can include multiple triggering methods. Optionally, when a trigger operation for a preset setup completion control is detected, the setup completion operation can be triggered; or, when it is detected that the received audio information includes a trigger word associated with setup completion, the setup completion operation can be triggered; or, when a shortcut instruction input by the user to represent setup completion is received, the setup completion operation can be triggered.

[0051] As another optional implementation of this embodiment, in the case of detecting an information setting operation for a loop information setting item, responding to the information setting operation. Then, the set loop operation information can be determined according to the information setting operation. Further, in the case of detecting a trigger operation for a preset setting completion control, the setting completion operation can be triggered. Then, in response to the setting completion operation, the set loop operation information is obtained, and the obtained loop operation information is used as the loop information to be detected corresponding to the area to be tested.

[0052] In this embodiment, there may be multiple ways to determine the target abnormal operating condition information corresponding to the area to be tested based on the circuit information to be tested, optionally including determining the abnormal operating condition information corresponding to the circuit information to be tested based on predetermined circuit condition corresponding information, and using the determined abnormal operating condition information as the target abnormal operating condition information corresponding to the area to be tested; or, when obtaining the circuit information to be tested, analyzing the circuit information to be tested according to a preset electrical circuit analysis logic, so as to determine the target abnormal operating condition information corresponding to the area to be tested based on the analysis results, etc.

[0053] As an optional implementation of this embodiment, when a trigger operation for a preset loop information retrieval control is detected, a loop information display interface can be displayed, and the loop information display interface can include loop identifiers of multiple loop information stored corresponding to the area to be tested. Further, when a selection trigger operation for any loop identifier is detected, the loop information corresponding to the loop identifier can be retrieved from the database, and the loop information can be used as the loop information to be detected. Further, in the case of the loop information to be detected, the abnormal operating condition information corresponding to the loop information to be detected can be determined based on the predetermined loop operating condition corresponding information, and the determined abnormal operating condition information can be used as the target abnormal operating condition information corresponding to the area to be tested.

[0054] S130. Display target abnormal operating condition information based on the electrical circuit diagram.

[0055] In this embodiment, in order to display the target abnormal operating condition information more clearly and intuitively, and enable relevant personnel to clearly and quickly locate the fault, when the target abnormal operating condition information corresponding to the area to be tested is obtained, the target abnormal operating condition information can be displayed based on the electrical circuit diagram, so that the abnormal secondary equipment and / or the cause of the equipment abnormality in the target abnormal operating condition information can be displayed in the electrical circuit diagram.

[0056] In this embodiment, the target abnormal operating condition information can be displayed in a preset display form based on the electrical circuit diagram. Optionally, the preset display form includes highlighting and / or distinguishing display.

[0057] Optionally, the target abnormal operating condition information is displayed based on the electrical circuit diagram, including: when the target abnormal operating condition information includes faulty secondary equipment, the faulty secondary equipment is highlighted in the electrical circuit diagram; when the target abnormal operating condition information includes the cause of the result abnormality, the cause of the result abnormality is displayed at a preset position in the electrical circuit diagram.

[0058] Among them, highlighting can include displaying the display color of the faulty secondary device in the electrical circuit diagram in a preset color; or controlling the faulty secondary device to flash in the electrical circuit diagram at a preset frequency, etc. The preset color can be any color that is different from the display colors of other secondary devices in the electrical circuit diagram, and can be red, yellow, or orange, etc. The preset frequency can be any frequency, and can be flashed once or twice per second. The preset position can be any position in the electrical circuit diagram, and can be the middle position, top position, or bottom position in the electrical circuit diagram, etc.

[0059] As an optional implementation of this embodiment, when the target abnormal operating condition information is obtained, the information included in the target abnormal operating condition information can be analyzed. Further, when the target abnormal operating condition information includes a faulty secondary device, the display color of the faulty secondary device in the electrical circuit diagram can be displayed in a preset color. When the target abnormal operating condition information includes a result abnormal cause, the result abnormal cause can be displayed at a middle position in the electrical circuit.

[0068] Optionally, the target interface also includes an operating condition information setting item; the method also includes: receiving an information setting operation for the operating condition information setting item through the target interface, and determining simulated abnormal operating condition information based on the information setting operation; in response to an operating condition operation request, controlling the electrical circuit diagram to operate the simulated abnormal operating condition information, and obtaining circuit operation information corresponding to the simulated abnormal operating condition information; and determining circuit operating condition corresponding information based on the simulated abnormal operating condition information and the circuit operation information.

[0069] Among them, the operating condition information setting item can be an operation entry for setting simulated operating condition information. The information setting operation can be an operation for setting simulated operating condition information to be run in the electrical circuit diagram. The operating condition operation request can be understood as an instruction for requesting the operation of the operating condition. The operating condition operation request can include multiple generation methods. Optionally, when a trigger operation for a preset operating condition operation control is detected, a operating condition operation request can be generated; or, when it is detected that the received audio information includes a trigger word associated with the operating condition operation, a operating condition operation request can be generated; or, when a operating condition operation trigger instruction input by the user is received, a operating condition operation request can be generated.

[0070] As an optional implementation of this embodiment, an information setting operation can be input for the operating condition information setting item in the target interface to set the operating condition information. Further, in the case of receiving the information setting operation input for the operating condition information setting item, the set simulated abnormal operating condition information can be determined according to the information setting operation. Further, in the case of detecting a trigger operation for a preset operating condition operation control, the electrical circuit diagram displayed in the target interface can be controlled to run the simulated abnormal operating condition information. Further, the loop operation information can be obtained after the operation ends. Then, a correspondence between the simulated abnormal operating condition information and the loop operation information is established, and the loop operating condition corresponding information is determined according to the correspondence.

[0071] For example, continue to refer to Figure 2 , assuming that the simulated abnormal working condition information is 1QD.1 grounded, at this time, the voltage source U1 is input from 1ZD.1-1ZD.6, and the loop operation information is shown as loop 1ZD.1-1QD.1 short circuit, and the simulated voltage source overcurrent alarm. Assuming that the simulated abnormal working condition information is 2D.6-3D.6 disconnected, at this time, the voltage source U1 is input from 1ZD.1-1ZD.6, and the loop operation information is shown as the loop is disconnected and there is no current in the loop. Assuming that the simulated abnormal working condition information is an internal fault of the K1 relay, at this time, the voltage source U1 is input from 1ZD.1-1ZD.6, and the loop operation information is shown as K1 not energized and K1 node 1 is not closed.

[0072] It should be noted that the normal operating condition information can also be set based on the operating condition information setting item, and then the electrical circuit diagram is controlled to operate the normal operating condition information to obtain the circuit operation information. Further, a correspondence between the normal operating condition information and the circuit operation information can be established, so that when the input operation result is normal circuit operation information, the normal operating condition information corresponding to the circuit operation information can be determined based on the correspondence.

[0073] It should also be noted that the advantage of using electrical circuit diagrams for simulation is that it is possible to reproduce various complex secondary circuits without having to be on site at the substation, demonstrate their working principles, reproduce the circuit working phenomena under various abnormal working conditions, avoid the safety risks that may be caused by on-site operations, minimize on-site work investment, and improve work efficiency and safety.
