[0084] Example 1

[0085] Figure 1 This is a flowchart of a substation transformation method provided in Embodiment 1 of the present invention. The method can be executed by a substation transformation device, which can be implemented in hardware and / or software and can be configured in an edge computing gateway.

[0086] The development of power grids has brought about requirements for datafication, networking, intelligence, and integration. As one of the core components of power transmission and transformation, substations are undergoing intelligent development. This intelligence is reflected in the coordinated, unified, and centralized management of video surveillance systems, fire protection systems, and perimeter alarm systems within substations. It also enables remote monitoring of the status of high-voltage operating equipment and remote monitoring of air conditioning, heating systems, lighting systems, and centralized drainage systems.

[0087] The growth of various devices in substations is very rapid, generating a large amount of data. Therefore, edge computing gateways are deployed in locations that are physically close to the substation.

[0088] Edge computing refers to processing information at the edge of a substation, close to the substation itself. It reduces the distance between equipment and operations (such as monitoring) within the substation by distributing processes. Data storage and computation are closer to the devices that create the data within the substation, rather than transmitting data to a distant central location. Storing and computing data on the devices that collect it addresses latency issues that can negatively impact application performance, especially in real-time data processing applications. By performing these processes locally, the amount of data processed in cloud-based location-based computing is significantly reduced, thus lowering costs.

[0089] An edge computing gateway (also known as an edge gateway) extends cloud functionality to local edge devices, enabling edge devices to respond quickly and autonomously to local events and provide low-latency, low-cost, privacy-preserving, and locally autonomous local computing services.

[0090] For example, an edge computing gateway can be deployed near a substation in the power grid. This edge computing gateway supports the following functions:

[0091] Dual-wide voltage (DC / AC 85V~265V) reverse connection protection;

[0092] Supports 2G / 3G / 4G / 5G mobile communication technologies;

[0093] Supports local and remote configuration maintenance and real-time data monitoring;

[0094] Data acquisition from up to 64 devices, supporting MODBUS-RTU or MODBUS-TCP protocols;

[0095] It supports data transmission via breakpoint resume, XML (eXtensible Markup Language), and JSON (JavaScript Object Notation).

[0096] Supports standard 8GB SD (Secure Digital) cards;

[0097] Multiple alarm settings for each device;

[0098] Kernel optimization enables industrial-grade chips;

[0099] The entire machine passed the Level 4 electromagnetic compatibility test.

[0100] All communication terminals have undergone a 2KV power frequency withstand voltage test;

[0101] Instrument information points can be automatically generated with one click;

[0102] Supports optional and full-selection single-table structure for forwarding datasets;

[0103] It supports batch operations and can be configured with efficient step size filling and other efficient configuration methods.

[0104] like Figure 1 As shown, the method includes:

[0105] Step 101: Send the transformer path in the substation and the transformer standard of each transformer point on the transformer path to the management terminal to notify the substation administrator to perform transformer operation on the transformer points along the transformer path according to the transformer standard.

[0106] In practice, substation administrators log in to the management terminal using information such as account and password, for example, mobile phones, smart wearable devices (such as watches), etc.

[0107] When performing a transformer operation, the edge computing gateway can generate a valid transformer path according to the transformer specification. The transformer path contains multiple transformer points (such as electrical devices like disconnectors).

[0108] For each transformer point, a voltage transformer can be pre-set. The function of the voltage transformer is to transform the high voltage into a standard secondary voltage of 100V or lower according to a proportional relationship, so that it can be used by protection, metering and instrumentation devices.

[0109] At the same time, voltage transformers can isolate high voltage from electrical workers. Although voltage transformers also operate on the principle of electromagnetic induction, their electromagnetic structure is exactly the opposite of that of current transformers.

[0110] The primary coil of a current transformer is wound with thick wire, with only one or a few turns, resulting in extremely low impedance. When the primary coil is connected in series in the circuit under test, the voltage drop across it is minimal. Although the secondary coil has more turns, its electromotive force E2 is not high under normal conditions, only a few volts.

[0111] Therefore, the current through the load is equal to the product of the current measured by the secondary coil and the current conversion ratio Ki. If the ammeter is used with a dedicated current transformer, the scale of the ammeter can be marked according to the current value in a high-current circuit.

[0112] The maximum secondary current of a current transformer is typically designed to be a standard value of 5A. Different current transformers are used for circuits with different currents, and their transformation ratios include 10 / 5, 20 / 5, 30 / 5, 50 / 5, 75 / 5, 100 / 5, etc.

[0113] In general, there is an execution sequence among multiple transformer points to ensure the safety of transformer operation.

[0114] In addition, each transformer point is configured with a valid transformer standard according to the transformer specification, that is, the standard action for performing transformer operation at that transformer point.

[0115] At this time, the edge computing gateway can send the transformer path in the substation and the transformer standard of each transformer point on the transformer path to the management terminal, thereby notifying the substation administrator to perform transformer operation on each transformer point in sequence according to the transformer standard along the transformer path.

[0116] In one embodiment of the present invention, step 101 may include the following steps:

[0117] Step 1011: Send multiple substations to the management terminal.

[0118] In this embodiment, the edge computing gateway can manage the terminal to send multiple substations managed by the edge computing gateway. The management terminal can display multiple substations on the interface for the administrator to browse and select.

[0119] Step 1012: When a selection operation triggered by the management terminal for a certain substation is received, the transformer points of the substation are planned to form a transformer path.

[0120] The administrator can trigger a selection operation on a substation by clicking on the interface, thereby selecting the substation waiting for transformation and entering the transformation operation parameters (such as bus ID, transformation rate, etc.). At this time, the management terminal sends the selection operation (including the transformation operation parameters) to the edge computing gateway. The edge computing gateway plans the path for each transformation point in the substation selected by the administrator according to the transformation operation parameters. The transformation points are arranged in sequence to form the transformation path.

[0121] Furthermore, in enclosed substations, edge computing gateways use satellite positioning components to locate parameters such as the substation's extent, the position of each transformer point within the substation, and the distance between transformer points. Based on these parameters, the substation can be flexibly divided into multiple transformer zones. Different types of voltage transformers can be assigned to different transformer zones according to the substation's needs, allowing the same type of voltage transformer to be configured at transformer points within the same transformer zone. This facilitates substation management. Moreover, voltage transformers can be guided to sensors at specific transformer points as needed, improving transformer service quality and intelligent management levels.

[0122] Therefore, the edge computing gateway can plan multiple transformer points to form a transformer path in the transformer area.

[0123] Step 1013: Query the transformer standard for each transformer point.

[0124] In this embodiment, transformer standards can be pre-configured for each transformer point according to the transformer specifications, and the transformer standards can be stored in a database.

[0125] The transformer standard can be a general standard set for different types of transformer operations, or it can be a personalized standard set for specific transformer operations. This embodiment does not impose any restrictions on this.

[0126] For common standards, the edge computing gateway can search for transformer standards in the database based on the transformer point ID.

[0127] For specific standards, the edge computing gateway can search for transformer standards in the database based on the transformer point ID and the type of transformer operation.

[0128] Step 1014: Send the transformer path and transformer standards of each transformer point to the management terminal to notify the substation administrator to perform transformer operations on the transformer points along the transformer path and according to the transformer standards.

[0129] The edge computing gateway sends the transformer path and the transformer standards of each transformer point to the management terminal. The management terminal displays the transformer path and the transformer standards of each transformer point on the interface, thereby notifying the substation administrator to perform transformer operations on each transformer point in sequence according to the transformer standards along the transformer path.

[0130] Step 102: Receive the first sensing data collected by the data acquisition device.

[0131] Data acquisition devices have been deployed at the transformer points within the substation. These data acquisition devices are sensors that sense the transformer points. They can be configured according to the actual situation of the transformer points. They can be a single device or a sensor composed of multiple independent devices. This embodiment does not impose any restrictions on this.

[0132] In one example, the type of data acquisition device is a road high-position video surveillance device.

[0133] In another example, the data acquisition devices are disconnect switches and high-position video monitoring terminals.

[0134] Among them, a disconnecting switch is a switching device used to isolate power supply, perform switching operations, and connect and disconnect small current circuits.

[0135] A disconnecting switch is a switching device without arc extinguishing function. It opens and closes circuits when there is no load current. Its main functions are to isolate the electrical equipment to be maintained from the live parts of the power grid, so that the electrical equipment under maintenance has a clear disconnection point from the power supply to ensure the safety of maintenance work; to change the operating mode for switching operations; and to connect and disconnect small current circuits.

[0136] In practical applications, the data acquisition device can collect first sensing data at the transformer point and send the first sensing data to the edge computing gateway wirelessly (such as via 5G). Correspondingly, the edge computing gateway can receive the first sensing data collected by the data acquisition device at the transformer point wirelessly.

[0137] The first sensing data includes voltage data when the voltage transformer at the transformer point changes.

[0138] Generally, this voltage data indicates whether the voltage transformer at the transformer point is in use, and does not necessarily need to be a specific parameter such as the voltage value.

[0139] Of course, in addition to voltage data, the first sensing data may also include other data, such as coordinate data when detecting voltage data, first time information, video data, etc. This embodiment does not limit this.

[0140] Step 103: Receive the second sensing data collected by the management terminal.

[0141] The management terminal has a satellite positioning component. During the transformer operation, it can call the satellite positioning component in real time to locate the current location data, encapsulate the location data into the second sensing data, and send the second sensing data to the edge computing gateway. Correspondingly, the edge computing gateway can receive the second sensing data collected by the management terminal wirelessly.

[0142] The second sensing data includes location data.

[0143] Of course, in addition to location data, the second sensing data may also include other data, such as second time information, etc., and this embodiment does not limit this.

[0144] Step 104: Calibrate the voltage and position data.

[0145] The edge computing gateway can calibrate the voltage data collected by the data acquisition device with the location data collected by the management terminal to determine whether the voltage data collected by the data acquisition device and the location data collected by the management terminal are consistent with the transformer operation.

[0146] In the specific implementation, the coordinate data and first time information when detecting voltage data are queried from the first sensing data. Since the voltage transformation operation is a continuous operation, the first time information can be the start time of the voltage transformer starting to generate voltage data, the stop time of the voltage transformer ending to generate voltage data, and the duration of the voltage transformer continuously generating voltage data.

[0147] Second time information when querying detection location data from second sensing data.

[0148] The first difference between coordinate data and location data is calculated using methods such as Euclidean distance.

[0149] Calculate the second difference between the first time information and the second time information.

[0150] If the first difference is less than or equal to a preset first threshold and the second difference is less than or equal to a preset second threshold, it indicates that the data acquisition device and the management terminal are relatively close within a short period of time, and it can be determined that the voltage data and the location data match.

[0151] If the first difference is greater than the preset first threshold, or the second difference is greater than the preset second threshold, it indicates that the data acquisition device and the management terminal have not been in close proximity in a short period of time, and it can be determined that the voltage data and the location data do not match.

[0152] In cases of mismatch, it could be that the management terminal has disabled the satellite positioning component or has not authorized the satellite positioning component, resulting in empty location data collected by the management terminal. It could also be that personnel other than the substation administrator have entered the substation and performed unauthorized operations on the transformer points, and so on.

[0153] Step 105: If the calibration voltage data matches the location data, it is determined that the substation administrator has performed the transformation operation on the transformation point in accordance with the transformation standard.

[0154] If the data acquisition device and the management terminal are close to each other within a short period of time, it can be assumed that the data acquisition device and the substation administrator are close to each other within a short period of time. Under normal circumstances, the substation administrator performs legal transformation operations on the transformation point in accordance with the transformation standard. Therefore, it can be assumed that the substation administrator has performed transformation operations on the transformation point in accordance with the transformation standard.

[0155] In this embodiment, the edge computing gateway sends the transformer path in the substation and the transformer standards of each transformer point along the transformer path to the management terminal. This notifies the substation administrator to perform transformer operations at the transformer points along the transformer path according to the transformer standards. Data acquisition devices have been deployed at the transformer points within the substation. The gateway receives first sensing data collected by the data acquisition devices, which includes voltage data when voltage transformers at the transformer points change. It also receives second sensing data collected by the management terminal, which includes location data. The voltage data and location data are calibrated. If the calibrated voltage data matches the location data, it is determined that the substation administrator has performed transformer operations at the transformer points according to the transformer standards. Considering the independence of the substation and its minimal external interference, this embodiment utilizes the matching of voltage data from voltage transformers at the transformer points with location data from the management terminal to achieve reasonable monitoring of the substation. This ensures the accuracy of identifying transformer operations, thereby guaranteeing the safe and efficient operation of the substation. This process does not rely on high-definition video data, consumes less bandwidth, has lower transmission latency, and can expand the monitoring area.

[0156] Example 2

[0157] Figure 2 This is a flowchart of a substation transformation method provided in Embodiment 2 of the present invention. This embodiment adds an error message operation based on the previous embodiment. Figure 2 As shown, the method includes:

[0158] Step 201: Send the transformer path in the substation and the transformer standard of each transformer point on the transformer path to the management terminal to notify the substation administrator to perform transformer operation on the transformer points along the transformer path according to the transformer standard.

[0159] Data acquisition devices have been deployed at the transformer points within the substation.

[0160] Step 202: Receive the first sensing data collected by the data acquisition device.

[0161] The first sensing data includes voltage data when the voltage transformer at the transformer point changes.

[0162] Step 203: Receive the second sensing data collected by the management terminal.

[0163] The second sensing data includes location data.

[0164] Step 204: Calibrate the voltage and position data.

[0165] Step 205: If the calibration voltage data does not match the location data, it is determined that the substation administrator did not perform the transformation operation on the transformation point in accordance with the transformation standard.

[0166] If the data acquisition device and the management terminal are not close together in a short period of time, it can be assumed that the data acquisition device and the substation administrator are not close together in a short period of time. There is a certain probability that the substation administrator will not perform the transformation operation on the transformation point according to the transformation standard.

[0167] Step 206: Generate an error message.

[0168] Step 207: Send the abnormality message to the quality inspection terminal to inform the substation quality inspector that the substation administrator did not perform the transformation operation at the transformation point in accordance with the transformation standard.

[0169] In practice, substation quality inspectors log in to the quality inspection terminal using information such as account and password, for example, mobile phones, smart wearable devices (such as watches), etc.

[0170] The edge computing gateway can generate anomaly alerts when a substation administrator fails to perform transformer operations according to transformer standards. These alerts are then sent wirelessly (e.g., via 5G) to a quality inspection terminal, which displays the alerts on its interface. The alerts inform the substation quality inspector that the administrator has not performed the transformer operations according to standards. Upon viewing the alerts, the quality inspector will then check the administrator's procedures for performing the transformer operations.

[0173] Step 301: Send the transformer path in the substation and the transformer standard of each transformer point on the transformer path to the management terminal to notify the substation administrator to perform transformer operation on the transformer points along the transformer path according to the transformer standard.

[0174] Data acquisition devices have been deployed at the transformer points within the substation.

[0175] Step 302: Receive the first sensing data collected by the data acquisition device.

[0176] The first sensing data includes voltage data when the voltage transformer at the transformer point changes.

[0177] Step 303: Receive the second sensing data collected by the management terminal.

[0178] The second sensing data includes location data.

[0179] Step 304: Calibrate the voltage and position data.

[0180] Step 305: If the calibration voltage data matches the location data, it is determined that the substation administrator has performed the transformation operation on the transformation point in accordance with the transformation standard.

[0181] Step 306: When the substation administrator has performed the transformation operation on the transformation point in accordance with the transformation standard, the transformation time of the transformation point is recorded.

[0182] In this embodiment, when it is determined that the substation administrator has performed the transformation operation on the transformation point in accordance with the transformation standard, a timer can be started and used to count the duration of the transformation operation on the transformation point, which is recorded as the transformation duration.

[0183] Step 307: Generate cost information for transformer operation based on transformer duration.

[0184] Step 308: Send the fee information to the management terminal for display.

[0185] In this embodiment, the edge computing gateway can generate cost information for the voltage transformation operation based on the voltage transformation duration.

[0186] In an example of cost information, the transformation time can be multiplied by the unit price corresponding to the transformation operation to obtain the total price. Discount information can then be generated based on the total price, and so on.

[0187] In another example of cost information, the duration of the pressure change can be divided into multiple gradient periods. The gradient is positively correlated with the unit price corresponding to the pressure change operation. That is, the higher the gradient, the higher the unit price corresponding to the pressure change operation, and the lower the gradient, the lower the unit price corresponding to the pressure change operation. Multiply the period by the unit price corresponding to the pressure change operation to obtain the stage price, and sum the stage prices to obtain the total price.

[0188] The edge computing gateway wirelessly sends the cost information to the management terminal, which displays the cost information in real time on the interface for the substation administrator to view and refer to.

[0189] Step 309: Read the transformer data collected from the transformer point from the first sensing data.

[0190] Step 310: Send the transformer data to the management terminal for diagnosis.

[0191] In this embodiment, the edge computing gateway can read the transformer data collected from the transformer point from the first sensing data, such as transformer path, sensor operating status, voltage value, etc., encapsulate the transformer data into a data packet, and send the data packet to the management terminal wirelessly.

[0192] When the management terminal receives a data packet, it reads the transformer data from the data packet and uses the transformer data to diagnose the transformer operation.

[0193] The diagnosis includes self-diagnosis and manual diagnosis. Taking self-diagnosis as an example, a self-diagnosis applet can be written in advance using a combination of HTML5 (HyperText Markup Language 5), CSS (Cascading Style Sheets), Java, etc. The management terminal inputs the transformer data into the self-diagnosis applet to diagnose the transformer operation and detect whether there are any abnormalities in the transformer operation, thereby ensuring the safe execution of the transformer operation.
