Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to an abnormality analysis method, device, equipment, medium and product for a substation. Background Art

[0002] With the continuous development of intelligent operation and maintenance technology of substations, emerging technologies such as remote monitoring, automation, and the Internet of Things have been continuously introduced, and the unmanned mode of substations has been fully promoted and applied. With the continuous deepening of the modeling construction of secondary equipment and secondary circuits, the demand for intelligent automatic diagnosis and positioning of faults and abnormal signals has become increasingly prominent.

[0003] Currently, after an abnormal alarm signal appears in the equipment, the operating personnel will first arrive at the site to collect abnormal information. Due to the limitations of technical capabilities and technical fields, when encountering most abnormal signals, especially abnormal signals involving secondary circuit faults, the operating personnel find it difficult to deal with them on their own, and they need to notify maintenance personnel to arrive at the site to troubleshoot the faults. This will delay the operation for several hours or even longer, posing a major hidden danger to the safe operation of the power system and being very inefficient. When analyzing abnormal signals, maintenance personnel will first collect alarm-related data, rely on alarm logic and related technical experience to determine the abnormal circuit, and then review the relevant drawings of each panel cabinet, find the relevant contacts, measure the contact potential and perform logical analysis, and finally give a diagnosis result. This will consume a lot of manpower and material resources, and the correctness of the diagnosis result is directly related to the technical capabilities of the personnel, and the accuracy cannot be guaranteed.

[0029] Embodiment 1

[0030] Figure 1 It is a flow chart of a substation abnormality analysis method provided in Example 1 of the present invention. This embodiment can be applied to the situation where secondary circuit analysis of the substation is performed to realize abnormality diagnosis and positioning. The method can be executed by the substation abnormality analysis device, and the substation abnormality analysis device can be implemented in the form of hardware and / or software.

[0031] like Figure 1 As shown, the method includes:

[0032] S101. When an abnormal alarm signal is generated in a substation, device parameter information of a target device corresponding to the abnormal alarm signal is determined from a substation configuration description file.

[0033] In this embodiment, the abnormal alarm signal can be understood as an alarm signal automatically generated when an abnormal situation occurs in the substation. The substation configuration description file (SCD) is used to describe the information of all devices in the entire substation. The substation contains multiple intelligent electronic devices (IEDs), and the target device is the IED device that generates an abnormal alarm signal among all IED devices in the substation. The device parameter information can be understood as the relevant information of the target device, at least including the device attribute information of the target device, and can also include other relevant information of the device.

[0034] Specifically, when an abnormal alarm signal mapped by a trigger source logic is generated in the substation, the abnormal diagnosis logic of the signal is triggered, and the device parameter information of the target device that issued the alarm signal is determined from the substation configuration description SCD file. Among them, the trigger source logic is the abnormal situation information recorded in the book, and there are multiple trigger source logics in the substation.

[0035] S102: Acquire a universal diagnosis template corresponding to the device type of the target device, and instantiate and map the universal diagnosis template based on device parameter information to obtain an instantiated diagnosis template corresponding to the target device.

[0036] In this embodiment, the equipment type can be understood as the types of various types of equipment in the substation, including protection, measurement and control, merging units, intelligent terminals and other types. The universal diagnostic template can be understood as a diagnostic template corresponding to a certain type of equipment. It is a universal diagnostic template for this type of equipment. The universal diagnostic template is based on the alarm signal logic of various types of equipment and is a signal abnormality diagnosis template established in combination with the alarm signal troubleshooting experience. The universal diagnostic template corresponds one-to-one to the equipment type. The instantiated diagnostic template can be understood as a diagnostic template corresponding to a specific device. A type of equipment may include multiple different devices, each with its own characteristics. The instantiated diagnostic template is a diagnostic template that is more highly associated with the device based on the device characteristics.

[0037] Whether it is a generalized diagnostic template or an instantiated diagnostic template, it is the reverse deduction of the signal alarm principle logic, and includes a signal template (Signal Point) and a logic template (Logical library). The signal template includes a signal point group information item (EventGroup) and a device attribute item, and the logic template includes a loop logic judgment template and a component contact search template. The loop logic judgment template is the diagnostic logic, and the component contact search template is the loop component search template and the loop contact search template included in the sub-diagnosis result. In a substation, each device has its associated intelligent electronic device, which is referred to as an associated device, or an IED associated device.

[0038] Among them, the signal template is used to collect the specific information of the device, and the logic template is used to perform abnormal diagnosis and judgment. The signal template specifically includes device attribute items and multiple signal point group information items. The signal point group information items correspond to the current device (target device) and its associated devices. The current device has its corresponding signal point group information items. The current device has multiple associated devices, and each associated device also has its corresponding signal point group information items. The signal point group information items can be understood as a collection of signal point information items (Event). Each device has multiple corresponding signal point information items. The attribute information of the signal point group information item includes the device name (name) of the current device, the associated type (iedRel) of the associated device, and the device type (iedType) of the associated device. The attributes of the signal point information item include the signal point name. The device attribute items can be understood as the device attributes of the current device (target device), including voltage level (voltlevel), wiring mode (cnnMode), interval type (primType), and device type (secoType).

[0039] Among them, the logic template includes multiple trigger source logics (source); each trigger source logic includes diagnostic logic (logical); the diagnostic logic includes diagnostic results (failure point); the diagnostic results include fault loops (event), alarm levels (level), alarm reasons (reason), impact ranges (reach) and processing suggestions (suggestion), and the diagnostic results are composed of multiple sub-diagnostic results (sublogical), each sub-diagnostic result includes a loop element search template (loopelement) and a loop contact search template (loop contact); the loop element search template includes the element type and the element information content, the element type includes circuit breakers and pressure plates, the element information content includes the room number, room name, panel number, panel name, equipment number, equipment name to which the element belongs, and also includes the element number and element name; the loop contact search template includes the loop starting point information and loop contact information, the loop contact information includes the room number, room name, panel number, panel name, equipment number, equipment name to which the loop contact belongs, and also includes the contact number.

[0040] The properties of the trigger source logic include the trigger source logic expression (condition); the properties of the diagnostic logic include the diagnostic logic expression (condition); the properties of the loop element search template include the loop signal point name (loop) and the logic trigger value (value); the properties of the loop contact search template include the loop signal point name (loop), the logic trigger value (value) and the loop type (looptype).

[0041] The signal template defines the voltage level, wiring method, interval type and device type of this device, and also includes its subordinate device information. The device information includes this device (target device) and the associated devices referenced in the logic template. The device information includes the device name (name), IED association type (iedRel), and IED device type (iedType), which are used to search for associated devices when SCD is instantiated. The signal point information (Event) is defined under the device information. The signal point information content includes defining the signal point name by referencing the standardized signal name.

[0042] The trigger source logic and diagnostic logic are defined in the logic template. The logical expressions all refer to the "device name + signal name" in the signal template. The trigger source logic is the action change of the alarm signal point. The diagnostic logic is the reverse deduction of the signal alarm principle logic. The diagnostic logic can contain sub-logic to divide the diagnostic logic more finely. The diagnostic logic defines the diagnostic result (failure point) when the logical condition is met. When the diagnostic result is located at a specific loop signal in the signal template, the loop element search template and loop contact search template of the diagnostic result signal are defined under the diagnostic logic. The loop element template contains the loop signal point name and logical trigger value. The loop contact template contains the loop signal point name, logical trigger value, and loop type. They are used for the instantiation mapping of the secondary loop model file (Substation Physical Configuration Description, SPD) and the determination of loop logic. The secondary loop model file SPD describes the physical loop connection relationship of the secondary loop in the substation.

[0043] Specifically, each device type has its corresponding universal diagnostic template. The universal diagnostic template corresponding to the device type of the target device is determined. The universal diagnostic template contains device attribute items. There is a correspondence between the device attribute items and the device attribute information in the device parameter information. Based on the correspondence between the two, the instantiation mapping of the target device is realized, and the loop contact information and loop starting point information corresponding to the target device in the secondary loop model file SPD are mapped to the universal diagnostic template to form a complete instantiation diagnostic template corresponding to the target device.

[0044] S103: Acquire device message data of the target device, perform abnormality diagnosis on the device message data by instantiating a diagnosis template, and determine an abnormality analysis result of the target device.

[0045] In this embodiment, the device message data can be understood as the message data of the target device based on a specific message protocol. The abnormal analysis data can be understood as the secondary circuit analysis results of the target device, including abnormal components and / or abnormal contacts.

[0046] Specifically, the manufacturing message specification (MMS) message data, sampled value (SV) message data, and general object oriented substation event (GOOSE) message data are collected in real time, and the message data is brought into the instantiated abnormal diagnosis template to obtain the actual value of the signal point information. These values ​​can be brought into the trigger source logic and the diagnosis logic. When the trigger source logic is judged to be satisfied, the abnormal diagnosis function is triggered. When a certain diagnostic logic is judged to be satisfied, the abnormal point can be pointed to the fault circuit (abnormal circuit) in the diagnosis result of the diagnostic logic, and the circuit and component search function in the logic is triggered. The circuit starting point information, circuit contact information, and circuit component information are searched through the instantiation information of the secondary circuit model file SPD as a troubleshooting guide to instruct the staff to collect relevant information through the troubleshooting guide. The circuit starting point information value, circuit contact information value (contact potential), and circuit component information value (component status) collected by the staff through the troubleshooting guide are obtained, and the fault signal is further diagnosed and located to determine the abnormal components and / or abnormal contacts of the target device.

[0047] An abnormality analysis method for a substation provided by an embodiment of the present invention includes determining the device parameter information of a target device corresponding to the abnormal alarm signal from a substation configuration description file when an abnormal alarm signal is generated in the substation; obtaining a universal diagnosis template corresponding to the device type of the target device, instantiating and mapping the universal diagnosis template based on the device parameter information to obtain an instantiated diagnosis template corresponding to the target device; obtaining the device message data of the target device, performing abnormal diagnosis on the device message data through the instantiated diagnosis template, and determining the abnormality analysis result of the target device. The above technical scheme diagnoses the faulty circuit as soon as the alarm signal is generated, and provides guidance on the location of the circuit contact. After inputting the contact potential information, the component-level and cable-level diagnostic positioning results are automatically completed. The efficiency and accuracy of abnormal signal diagnosis in substations are improved, and the safe and stable operation of power systems is promoted.

[0048] Embodiment 2

[0049] Figure 2 It is a flow chart of a substation abnormality analysis method provided in Embodiment 2 of the present invention. This embodiment is a further optimization of any of the above embodiments and can be applied to situations where secondary circuit analysis of a substation is performed to achieve abnormal diagnosis and positioning. The method can be executed by an abnormality analysis device of a substation, and the abnormality analysis device of the substation can be implemented in the form of hardware and / or software.

[0050] like Figure 2As shown, the method includes:

[0051] S201. When an abnormal alarm signal is generated in a substation, device parameter information of a target device corresponding to the abnormal alarm signal is determined from a substation configuration description file.

[0052] S202: Acquire a universal diagnosis template corresponding to the device type of the target device and a secondary circuit model file of the substation.

[0053] In this embodiment, the secondary circuit model file SPD is used to describe the physical circuit connection relationship of the secondary circuit in the substation.

[0054] Specifically, each device type has its corresponding universal diagnosis template, the device type of the target device is determined, and the universal diagnosis template corresponding to the device type of the target device is further determined. An SPD secondary circuit model file representing the circuit connection relationship within the substation is obtained.

[0055] S203: Instantiate and map the device attribute information in the device parameter information with the device attribute items in the universal diagnosis template to obtain an intermediate diagnosis template.

[0056] In this embodiment, the device parameter information is derived from the substation configuration description file SCD, and the device attribute information can be understood as the attribute information of the target device, including the voltage level, wiring mode, bay type and device type of the target device. The device attribute information is the actual specific information, and the device attribute item is a general description of the device attribute information. The intermediate diagnostic template can be understood as a generalized diagnostic template that has not been fully instantiated and mapped.

[0057] Specifically, there is a one-to-one mapping relationship between the device attribute information in the device parameter information and the device attribute items in the universal diagnostic template. Based on the mapping relationship between the two, instantiation mapping is performed. After mapping, an instantiation abnormal diagnosis template is generated with the IED device in the SCD file as the unit. The device name (IEDname) of the target device is added to the device attribute item of the signal template in the diagnostic template, and the SCD signal reference (instantiated signal reference) of each signal point is added to the signal point information item. The logical template remains unchanged. It can be understood that the template formed by the mapping at this time is only an instantiation mapping based on SCD, and does not involve an instantiation mapping based on SPD. Therefore, the diagnostic template formed by the mapping at this time is an intermediate diagnostic template that has not fully completed the instantiation mapping.

[0058] Optionally, the device attribute information in the device parameter information is instantiated and mapped with the device attribute items in the universal diagnosis template to obtain an intermediate diagnosis template, including:

[0059] S2031. Based on the correspondence between the device attribute information in the device parameter information and the device attribute items in the universal diagnosis template, map the universal diagnosis template to an intermediate diagnosis template corresponding to the target device.

[0060] In this embodiment, the device attribute information such as voltage level, wiring method, interval type and device type in the device parameter information is matched with the device attribute items such as voltage level, wiring method, interval type and device type in the universal diagnostic template to achieve mapping between the SCD file and the universal diagnostic template and form an intermediate diagnostic template.

[0061] S2032. Determine the device name and instantiation signal reference of the target device from the substation configuration description file, add the device name and instantiation signal reference to the intermediate diagnosis template, and improve the intermediate diagnosis template.

[0062] In this embodiment, the instantiated signal reference can be understood as a unique identifier of the signal, which is recorded in the SCD file. The reference information is written into the diagnosis template only after instantiation.

[0063] Specifically, the device name (IEDname) of the target device and the signal point reference (scdRef) of each signal point (contact) are obtained from the substation configuration description file SCD, that is, the instantiated signal reference, the device name attribute item is added to the device attribute item in the signal template, and the device name obtained from the SCD file is filled into the attribute item, and the instantiated signal reference information item is added to each signal point information item in the signal point group information item in the signal template, and the signal point reference obtained from the SCD file is filled into the information item. By filling in the signal template in the diagnostic template, the intermediate diagnostic template is improved.

[0064] It is understandable that this embodiment can also be to directly instantiate the SCD file and the universal diagnostic template for a certain device type to form an instantiated intermediate diagnostic template corresponding to the device type, and then further instantiate the intermediate diagnostic template based on the specific target device through the above steps S2031 and S2032 to improve the intermediate diagnostic template. After completing the SCD instantiation mapping corresponding to the universal diagnostic template and the target device, the corresponding IED device in the SCD file is found according to the IED association type and IED device type of the associated device of the target device, and the instantiation mapping of the subordinate signals of the associated device is completed based on the signal name.

[0065] S204. Add loop analysis guidance information to the intermediate diagnosis template through the secondary loop model file to form an instantiated diagnosis template corresponding to the target device.

[0066] In this embodiment, the loop analysis guidance information can be understood as information used to guide abnormal loop analysis, including at least loop contact information and loop element information, and may also include loop starting point information.

[0067] Specifically, through the secondary loop model file SPD, the component information in the loop is added under the loop element search template (loop element) in the logical template of the intermediate diagnosis template. The component types include circuit breakers, pressure plates and handles, etc. The information content includes the room number to which the component belongs, the room name, the panel number, the panel name, the equipment number, the equipment name, the component number and the component name; the loop starting point information and loop contact information are added under the loop contact search template (loop contact), and the information content includes the room number, room name, panel number, the panel name, the equipment number, the equipment name and the contact number to which the loop contact belongs, to realize the instantiation mapping based on SPD and generate a complete instantiation diagnosis template corresponding to the target device.

[0068] Optionally, loop analysis guidance information is added to the intermediate diagnosis template through the secondary loop model file to form an instantiated diagnosis template corresponding to the target device, including:

[0069] S2041. Determine the loop starting point information of the target device from the secondary loop model file through the associated device name and instantiated signal reference in the intermediate diagnosis model.

[0070] In this embodiment, the loop starting point information can be understood as relevant information of the starting point of the signal loop of the target device.

[0071] Specifically, the open-in contact of the signal loop on the backplane of the target device is defined as the starting point of the loop, and the starting point of the loop is matched with the signal point corresponding to the diagnostic result in the logical template (Logical library), and the corresponding "equipment name (IEDname) + signal reference (instantiated signal reference)" is found in the signal template, and the corresponding functional logic element (Component) is found in the SPD secondary loop model file according to the "IEDname + signal reference", and the corresponding contact element (pin) under the device element (device) is found according to the contact element (PinRef) contained in the subordinate template of the functional logic element, and this contact element (Pin) information is determined as the starting point information of the loop.

[0072] S2042: Determine loop contact information and loop element information corresponding to the loop starting point information, fill the loop contact information and loop element information into the intermediate diagnosis model, and form an instantiated diagnosis template corresponding to the target device.

[0073] In this embodiment, the loop point information can be understood as the relevant information of each point (signal point) in the signal loop of the target device. The loop component information can be understood as the relevant information of each component used in the signal loop of the target device.

[0074] Specifically, after finding the information of the starting point of the loop, find the corresponding full signal loop according to the contact element. The full signal loop includes the signal loop (open-in signal loop) and the voltage loop (voltage signal loop). By searching in the direction of the power supply through the signal loop and in the direction of the capacitor voltage transformer (CVT) terminal box through the voltage loop, interference from other loops can be removed, and only the full signal loop that needs to be found is retained. List the interface elements (Interface) involved in the full signal loop and their subordinate interface connection point elements (Point), and determine the information of the interface connection point elements as loop contact information.

[0075] Among them, the automatically generated loop contact information will be arranged in order from the loop starting point along the interface connection point element (loop contact) to the loop terminal, and the contact order will be automatically solidified. And the loop contact related information will display different attribute information according to the loop type (looptype) in the contact search template (loop contact). When the loop type is a voltage loop, the contact information will include a group of voltage measurement contacts, including input contacts (PinnameA) and common contacts (PinnameN). When the loop type is a signal loop, the contact information will be divided into two groups, searching in the positive power supply direction and the negative power supply direction respectively. The information only includes the input contact (PinnameA), and the single contact to ground potential is used as the contact potential information.

[0076] After finding the full signal loop to be searched, the circuit breakers and pressure plate devices involved in the full signal loop are listed, and the information of the circuit breakers and pressure plate devices is determined as loop device information.

[0077] After the loop contact information and loop element information of the target device are determined, the loop contact information and loop element information are filled into the intermediate diagnosis model to form an instantiated diagnosis template corresponding to the target device.

[0078] S205: Acquire device message data of the target device, input the device message data into the instantiated diagnosis template, and determine the abnormal circuit of the target device.

[0079] In this embodiment, the MMS, SV, and GOOSE message data of the target equipment in the substation are obtained, and these message data are brought into the instantiated diagnostic file to obtain the actual value of the signal point information. These values ​​can be brought into the trigger source logic and the diagnostic logic. When it is judged that the trigger source logic is satisfied, the abnormal diagnosis function is triggered. When it is judged that a certain diagnostic logic is satisfied, the abnormal point can be pointed to the fault circuit (abnormal circuit) in the diagnosis result in the diagnostic logic, and the circuit and component search function in the logic is triggered to search for the circuit starting point information, circuit contact information and circuit component information as a troubleshooting guide to instruct the staff to collect information through the troubleshooting guide.

[0080] S206, obtaining the component states of multiple target components and the contact potentials of multiple target contacts in the abnormal circuit, inputting each component state and contact potential into the instantiated diagnosis template, and determining the abnormal analysis results of the target device, wherein the abnormal analysis results include abnormal components and / or abnormal contacts.

[0081] In this embodiment, the target component can be understood as a key component in the circuit, such as a circuit breaker, a pressure plate, and a handle. The component state can be understood as a circuit component information value. The target contact can be understood as each contact in the circuit. The contact potential can be understood as a circuit contact information value.

[0082] Specifically, obtain the component status of multiple target components and the contact potential of multiple target contacts collected by the staff through the troubleshooting guidance, input the component status and contact potential into the instantiated diagnosis template, perform abnormal diagnosis through the logic template in the instantiated diagnosis template, obtain the number and name of the specific abnormal component such as circuit breaker or pressure plate, and the panel cabinet and terminal number information on both sides of the specific abnormal circuit segment, form the abnormal analysis result of the target equipment, and display it on the full signal circuit through the full circuit visualization display technology. Figure 3 is an example display diagram of an abnormal analysis result provided by the second embodiment of the present invention, such as Figure 3 As shown, the abnormal analysis result includes an abnormal component (circuit breaker), two abnormal contacts and a cable connection between the two abnormal contacts.

[0083] Among them, the logic template in the instantiated diagnosis template is based on certain specific principles in the circuit. It uses the characteristics that each contact voltage in the voltage circuit is the same, each contact potential in the signal circuit is the same, and the disconnection of the air switch pressure plate will cause the circuit to be disconnected. The relevant diagnostic logic is formulated so that the instantiated signal abnormality diagnosis file can complete the component-level and cable-level abnormality diagnosis and positioning functions. The specific contents of abnormality diagnosis through the logic template in the instantiated diagnosis template include:

[0084] Determine whether the component state is within the range of the component information value corresponding to the circuit component search template (usually the input signal circuit is set to 1, the voltage circuit is set to 58, the voltage circuit sets the threshold of error 2, and the actual representation of the component information value range in the voltage circuit is between 56-60). If the component state is not within the range of the component information value corresponding to the circuit component search template, it indicates that the component state does not match the expected state of the entire circuit, and the component is determined to be an abnormal component;

[0085] When the potential of the first contact inputted in sequence meets the condition of the information value in the loop contact search template (the potential of the contact is equal to the information value or within the threshold range of the information value), it is determined that the loop connection between the contact and the loop start point is abnormal; it can be understood that the first contact needs to have an information value (potential), if the first contact 1 has no value, then the second contact 2 with a value is determined as the first contact;

[0086] When the potential of one of the contacts does not satisfy the information value in the loop contact search template, but the condition of the next contact satisfies the information value in the loop contact search template, it is determined that there is a potential difference between the two contacts, and it is determined that the loop wiring between the two contacts is abnormal;
