Description

Technical Field

[0001] This invention relates to the field of monitoring new energy power plants, specifically to a centralized monitoring method and system for new energy power plants utilizing multi-source heterogeneous analysis. Background Technology

[0002] A renewable energy power station encompasses all equipment below the grid connection point of a hydroelectric power plant, wind farm, or solar power station that is centrally connected to the power system. This includes equipment such as transformers, busbars, transmission lines, converters, energy storage, hydroelectric generators, wind turbines, photovoltaic power generation equipment, reactive power regulation equipment, and auxiliary equipment. In a renewable energy power station, hydroelectric generators, wind turbines, and photovoltaic power generation equipment are the main energy conversion devices, converting natural energy sources such as hydropower, wind power, and solar energy into electrical energy for the power system. Transformers, busbars, and transmission lines are responsible for transmitting electrical energy from the generators to the power system, ensuring a stable power supply. Reactive power regulation equipment and auxiliary equipment are used to regulate the stability of the power system and improve power quality.

[0003] The existing centralized monitoring systems for new energy power plants mainly suffer from the following problems: First, new energy power plants are characterized by large areas, numerous and dispersed equipment, and complex environments. While automated inspection equipment, such as drones and robots, provides a new option for centralized monitoring, it is difficult to achieve truly fully automated inspections in practice. Manual intervention, operation, or on-site inspection by inspection personnel is often still required. This necessitates that inspection personnel possess solid professional knowledge of new energy power generation and be proficient in operating automated inspection equipment to complete various complex inspection tasks. Therefore, the company needs to organize multiple theoretical and operational training sessions in advance, assisting them in obtaining relevant qualification certificates, such as "civilian drone pilots," through specialized examinations. This not only incurs high training costs but also raises the issue of frequent inspection accidents even after passing the exams. Second, to achieve accurate monitoring of new energy power plants, it is necessary to acquire various information from different equipment nodes, including current, voltage, power, images, videos, temperature, humidity, wind speed, etc. Different equipment... Backup nodes have different locations and are subject to external interference. Relying solely on automatic inspection equipment is insufficient to achieve accurate positioning and secure information collection of equipment nodes. In most cases, manual intervention is still required to prevent safety accidents. How to ensure that automatic inspection equipment can quickly and safely reach the equipment nodes to be inspected is also a technical problem that urgently needs to be solved in this field. Third, automatic inspection equipment often collects a large amount of data, especially image and video information. If data transmission relies solely on its own communication module, issues such as lag and data congestion often occur, making it difficult for the back-end site monitoring personnel to quickly and accurately obtain the equipment's operating status information. Fourth, new energy power plants sometimes include multiple power generation types such as wind power, hydropower, and photovoltaic power. Different power generation types have different characteristics. For example, wind power generation has strong volatility, and weather events such as typhoons and cold waves can affect the output power of wind power generation. How to ensure the stability of power supply in new energy power plants with multi-energy coordinated operation is of great significance for improving the power generation efficiency of the power plant and ensuring the power safety of users.

[0017] Figure 1 A flowchart for a centralized monitoring method for new energy power plants utilizing multi-source heterogeneity analysis; Figure 2 This is a schematic diagram of data transmission for different inspection devices. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0019] In order to at least partially solve the technical problems raised in the background section, the present invention proposes the following technical solutions: A centralized monitoring method for new energy power plants utilizing multi-source heterogeneous analysis, such as Figure 1 As shown, it includes the following steps: Step 1: Use the first inspection equipment to obtain the identity information of the inspection personnel, and provide a set of operating modes that match the first inspection equipment and the identity information of the inspection personnel. Step 2: Select the first target operating mode from the set of operating modes, so that the first inspection equipment enters the first target operating module; Step 3: Verify the identity information of the inspection personnel and the operating mode of the first target. If the verification is correct, determine the data transmission and control relationship between the first and second inspection equipment. Step 4: Control the first inspection device to enter the first target operation mode, generate the corresponding monitoring interface, and adjust its control parameters for the second inspection device. Step 5: Instruct the inspection personnel to control the second inspection equipment to conduct inspections of the new energy power station based on the first inspection equipment which is in the first target operation mode.

[0020] In this embodiment of the invention, the first inspection device in step 1 above includes a smart wearable device and a virtual driving module.

[0021] Specifically, the identity information of inspection personnel includes: beginners, inspection instructors, actual inspection personnel, and remote inspection business guidance experts. Beginners refer to personnel with insufficient inspection experience, who have not obtained inspection qualification certificates, and who are unable to carry out inspection operations independently. Inspection instructors refer to personnel with rich inspection experience and inspection instruction qualifications who can provide operation demonstrations, practical guidance, and monitoring to beginners. Actual inspection personnel refer to personnel with certain inspection experience, who have obtained inspection qualification certificates, and who are able to carry out independent inspection operations. Remote inspection business guidance experts refer to personnel with extremely rich inspection experience who can provide remote inspection business guidance to actual inspection personnel. Optionally, the identity information of inspection personnel can be obtained based on account and password login, identity card, fingerprint, facial recognition, or other methods.

[0022] Step 1 above provides a set of operating modes that match the first inspection device and identity information, including: When the first inspection device is a virtual driving module, its operating modes include: virtual practice mode, practical demonstration and learning mode, practical remote guidance mode, remote inspection mode, and remote inspection business guidance mode. Different identity information is matched with different operating modes. When the first inspection device is a smart wearable device, its operating modes include: near-end practical practice mode, near-end practical teaching mode, and near-end actual inspection mode. Different identity information is matched with different operating modes.

[0023] Specifically: when the first inspection device is a virtual driving module and the inspection personnel are beginners, the corresponding set of operating modes can be virtual practice mode and practical demonstration learning mode; when the first inspection device is a smart wearable device and the inspection personnel are beginners, the corresponding set of operating modes can be near-end practical practice mode.

[0024] Beginners can use the virtual driving module to practice inspection operations virtually, and also to conduct practical demonstrations of inspection operations. During these demonstrations, the corresponding inspection instructors or remote inspection business guidance experts can use smart wearable devices for near-end practical instruction, control the second inspection equipment, and use the second inspection equipment to collect and inspect information from new energy power stations. At the same time, the smart wearable devices will acquire relevant information from the near-end practical instruction and send it to the virtual driving module for display, facilitating practical learning for beginners.

[0025] Beginners can use smart wearable devices for near-end practice. When conducting this near-end practice, beginners can use smart wearable devices to perform near-end control of the second inspection equipment. The smart wearable device will obtain relevant information about the near-end practice and send it to the virtual driving module for display. Corresponding inspection instructors or remote inspection business guidance experts can use the virtual driving module to provide remote guidance for practice.

[0026] When the first inspection device is a virtual driving module and the inspection personnel are inspection instructors, the corresponding set of operating modes can be virtual practice mode, remote practice guidance mode, and remote inspection mode; when the first inspection device is a smart wearable device and the inspection personnel are inspection instructors, the corresponding set of operating modes can be near-end practice instruction mode and near-end actual inspection mode.

[0027] Similarly, inspection instructors can use the virtual driving module to practice inspection operations virtually; provide remote guidance for beginners during near-end practice; conduct remote inspections of secondary inspection equipment using the virtual driving module; and use smart wearable devices for near-end practice instruction and actual near-end inspections. When inspection instructors conduct actual near-end inspections, corresponding remote inspection business guidance experts provide remote inspection business guidance based on the virtual driving module.

[0028] When the first inspection device is a virtual driving module and the inspection personnel are actual inspection personnel, the corresponding set of operating modes can be virtual practice mode and remote inspection mode; when the first inspection device is a smart wearable device and the inspection personnel are actual inspection personnel, the corresponding set of operating modes can be near-end actual inspection mode.

[0029] Similarly, actual inspectors can use the virtual driving module to practice inspection operations virtually; they can also use the virtual driving module to remotely inspect second inspection equipment; actual inspectors can also use smart wearable devices to conduct near-end actual inspections. When actual inspectors conduct near-end actual inspections, corresponding remote inspection business guidance experts provide remote inspection business guidance based on the virtual driving module.

[0030] When the first inspection device is a virtual driving module and the inspection personnel are remote inspection business guidance experts, the corresponding set of operating modes can be virtual practice mode, practice remote guidance mode, remote inspection mode, and remote inspection business guidance mode; when the first inspection device is a smart wearable device and the inspection personnel are remote inspection business guidance experts, the corresponding set of operating modes can be near-end practice teaching mode and near-end actual inspection mode.

[0031] Similarly, remote inspection business guidance experts can use the virtual driving module to practice inspection operations virtually; they can use the virtual driving module to remotely inspect second inspection equipment; they can provide remote practical guidance to beginners when they are practicing at close range; they can provide remote inspection business guidance to actual inspection personnel and inspection teaching personnel when they are conducting actual close range inspections; remote inspection business guidance experts can also use smart wearable devices to conduct close range practical teaching and close range actual inspections.

[0032] Given that remote inspection business guidance experts possess strong theoretical and practical inspection capabilities, they can conduct remote practical guidance, remote inspection, remote inspection business guidance, near-end practical demonstration, and near-end actual inspection.

[0033] The smart wearable device can be smart glasses or a smartwatch. It can be worn by inspection personnel with different identities and used for near-end practice, near-end practice teaching, and near-end actual inspection. The smart wearable device has a first display module, a first control module, and a first command interaction module. It can provide inspection personnel with inspection route navigation based on the first display module, and can also acquire and display the operating status and parameter information of the new energy power station in real time. It can also control the second inspection equipment near-end based on the first control module and the first command interaction module.

[0034] The virtual driving module comprises a second 3D display module, a second control module, and a second command interaction module. The second 3D display module can display the operating parameters and inspection-related information of the new energy power station in three dimensions. The second control module and the second command interaction module can modify and control the operating parameters and status of the new energy power station. The virtual driving module can be operated by inspection personnel with different identities and is used for virtual practice, practical demonstration and learning, remote practical guidance, remote inspection, and remote inspection business guidance. The second control module includes a virtual practice module that can generate virtual inspection practice scenarios where inspection personnel can practice inspection operations. The virtual driving module can remotely control the second inspection equipment.

[0035] The second inspection device can be a drone and / or a robot. The drone and / or robot has an information acquisition module, a third control module, and an automatic movement module. The information acquisition module includes at least a camera that can collect image and video information, and may also include sensors such as current, voltage, power, temperature, humidity, and wind speed. The second inspection device can collect information and inspect new energy power stations when conducting near-end practical exercises, near-end practical teaching, near-end actual inspection, practical demonstration and learning, practical remote guidance, remote inspection, and remote inspection business guidance. It can send the collected data information to the first inspection device for display, analysis, and processing. The smart wearable device can perform near-end control of the second inspection device, and the virtual driving module can perform remote control of the second inspection device.

[0036] like Figure 2 As shown, the virtual driving module, the smart wearable device, and the second inspection device are connected in communication.

[0037] In one feasible implementation, the virtual driving module can display or switch between displaying parameter information, images, and video information obtained by the second inspection equipment and the smart wearable device, which facilitates inspection and guidance by actual inspection personnel, inspection teaching personnel, and remote inspection business guidance experts.

[0038] In one feasible implementation, inspection personnel can use a smart wearable device to obtain and view inspection-related information collected by the second inspection device, and can also use the smart wearable device to remotely control the second inspection device, including: The camera focal length of the second inspection device can be remotely adjusted, making it easier for inspection personnel to view high-definition or global images of the target location.

[0039] In one feasible implementation, sensors at fixed locations can also be used to collect and acquire relevant information about new energy power station equipment.

[0040] In one feasible implementation, in an emergency, the virtual driving module can remotely take over control of the second inspection equipment and prohibit smart wearable devices from performing near-end control of the second inspection equipment.

[0041] In one feasible implementation, multiple second inspection devices can be networked to build a local area network to enhance the stability of their communication; a first QR code can be set on the equipment of the new energy power station to assist the second inspection devices in positioning, and the first QR code corresponds to the current accurate location information.

[0042] In one feasible implementation, several first and second inspection devices are set up at each power station. Considering that photovoltaic and wind power generation modules are neatly arranged, have relatively regular routes, and have definite inspection nodes, but cover a large area and are relatively dispersed, manual inspection is costly and inefficient. Inspection is carried out using a virtual driving module and the second inspection device. In remote inspection mode, the virtual driving module can control the second inspection device to inspect the new energy power station. Optionally, considering that hydropower generation covers a small area and is relatively concentrated, the virtual driving module, smart wearable devices, and the second inspection device are used together to inspect the new energy power station.

[0043] Step 2 above: Selecting the first target operating mode from the set of operating modes, so that the first inspection equipment enters the first target operating module, including: Step 21: The inspection personnel use the instruction interaction module of the first inspection equipment to select and determine the first target operating mode of the first inspection equipment under their control from the set of operating modes.

[0044] Step 22: The first inspection equipment includes a smart wearable device and a virtual driving module. Different combinations of their operating modes correspond to different inspection-related application scenarios.

[0045] The inspection-related application scenarios include: virtual practice, practical learning, remote inspection, and actual inspection providing remote business guidance.

[0046] Inspection personnel can use the virtual driving module to conduct virtual exercises related to inspections.

[0047] During practical learning, inspection and teaching personnel can wear smart wearable devices for near-field practical teaching, while beginners can enter the virtual driving module for practical demonstration and learning; alternatively, beginners can wear smart wearable devices for near-field practical practice, while inspection and teaching personnel can enter the virtual driving module for remote practical guidance.

[0048] During actual inspections, the virtual driving module can be used to remotely control the second inspection equipment for remote inspections. During actual inspections, the second inspection equipment can also be controlled locally using a smart wearable device. At the same time, the virtual driving module can provide remote business guidance. When providing remote business guidance, the virtual driving module can also temporarily remotely control the second inspection equipment for inspections.

[0049] Step 3 above: Re-verify the identity information of the inspection personnel and the operating mode of the first target. If there are no errors, determine the data transmission and control relationship between the first and second inspection devices, including: Step 31: When the first inspection device only includes the virtual driving module and the first target operation mode is virtual practice mode, directly enter the virtual practice.

[0050] Step 32: When the first inspection device only includes the virtual driving module and the first target operation mode is the remote inspection mode, verify whether the identity information of the inspection personnel matches the first target operation mode they selected. If they match, enter the remote inspection mode and use the virtual driving module to control the second inspection device to perform remote inspection. The second inspection device will send the collected data information to the virtual driving module.

[0051] Step 33: When the first inspection device includes a smart wearable device and a virtual driving module, verify whether the first target operating mode of the smart wearable device and the virtual driving module corresponds to the target inspection related application scenario.

[0052] The target inspection-related application scenarios include practical learning and actual inspections that provide remote business guidance; Step 34: Determine whether the identity information of the inspection personnel matches the target inspection-related application scenario. If there is a conflict, issue an alarm and ask them to make a new selection.

[0053] Step 35: Enter the relevant application scenario for the target inspection and determine the data transmission and control relationship between the first and second inspection devices.

[0054] Specifically, this includes steps 351 to 354.

[0055] Step 351: When the target inspection-related application scenario is practical learning, determine the inspection personnel identity information corresponding to the smart wearable device and the virtual driving module.

[0056] Step 352: Beginners can use the virtual driving module for practical demonstration and learning of inspection operations. During this demonstration and learning, the corresponding inspection instructor or remote inspection business guidance expert uses a smart wearable device for near-end practical instruction and near-end control of the second inspection equipment. The smart wearable device will obtain relevant information from the near-end practical instruction and send it to the virtual driving module for demonstration. Beginners can also use the smart wearable device for near-end practical practice and near-end control of the second inspection equipment. The smart wearable device will obtain relevant information from the near-end practical practice and send it to the virtual driving module for demonstration. The corresponding inspection instructor or remote inspection business guidance expert can then use the virtual driving module for remote practical guidance.

[0057] In one feasible implementation, after the near-end practical exercise is completed, the inspection instructor or the remote inspection business guidance expert can give a corresponding evaluation.

[0058] Step 353: When the target inspection-related application scenario is an actual inspection that provides remote business guidance, determine the identity information of the inspection personnel corresponding to the smart wearable device and the virtual driving module.

[0059] Step 354: The actual inspection personnel can use smart wearable devices to conduct near-end actual inspections. When the actual inspection personnel conduct near-end actual inspections, the smart wearable devices will obtain relevant information about the near-end actual inspections and send it to the virtual driving module for display. In case of emergency, the corresponding remote inspection business guidance expert will provide remote inspection business guidance based on the virtual driving module.

[0060] During inspection, the virtual driving module, smart wearable device and second inspection device have corresponding connection and control relationships, which are generally one-to-one connections and controls.

[0061] Step 4 above: The first inspection device enters the first target operation mode, generates the corresponding monitoring interface, and adjusts its control parameters for the second inspection device, including: Step 41: The first inspection equipment has different monitoring interfaces in different operating modes.

[0062] For example, in virtual practice mode, the monitoring interface of the virtual driving module mainly displays virtual practice scenarios related to inspection; in practice demonstration and learning mode and practice remote guidance mode, the monitoring interface of the virtual driving module mainly displays inspection-related parameter information and control information related to near-end practice teaching and near-end practice; in remote inspection mode and remote inspection business guidance mode, the monitoring interface of the virtual driving module mainly displays inspection-related parameter information and control information related to remote inspection and remote inspection business guidance; regarding the specific inspection-related parameter information and control information, no specific limitations are made here, and those skilled in the art can set them according to actual needs.

[0063] In the near-end practice training mode, near-end practice teaching mode, and near-end actual inspection mode, the monitoring interface of the smart wearable device mainly displays parameter information and control information related to the near-end control of the second inspection device and the operation parameters and status display of the station equipment.

[0064] Step 42: Adjust the control parameters of the second inspection equipment based on the identity information of the inspection personnel. The control parameters of the second inspection equipment include: the speed limit of the second inspection equipment, the priority of the control command to the second inspection equipment, and the size of the obstacle avoidance safety range of the second inspection equipment.

[0065] The speed limit of the second inspection equipment and the priority of their respective control commands to the second inspection equipment increase sequentially for beginners, actual inspectors, inspection instructors, and remote inspection business guidance experts; the obstacle avoidance safety range of their respective second inspection equipment decreases sequentially under the same conditions.

[0066] The same conditions can be the same speed and the same external environment.

[0067] In one feasible implementation, the second inspection device has an obstacle avoidance safety range, which can be spherical. The size of the obstacle avoidance safety range can be adjusted based on the speed of the second inspection device; the greater the speed, the larger the obstacle avoidance safety range. When an object is detected entering the obstacle avoidance safety range, the speed is reduced to avoid collision.

[0068] Step 5 above: The inspection personnel control the second inspection equipment to conduct inspections of the new energy power station based on the first inspection equipment operating in the first target mode, including: Step 51: When the first inspection equipment only includes a virtual driving module and it is running in remote inspection mode, the inspection personnel can use the virtual driving module to remotely control the second inspection equipment to inspect the new energy power station.

[0069] Step 52: When the first inspection equipment includes a virtual driving module and a smart wearable device, determine the target inspection-related application scenarios.

[0070] Step 53: When the target inspection-related application scenario is practical learning, beginners and inspection instructors can control the virtual driving module and smart wearable device respectively to jointly complete the practical learning task.

[0071] Step 54: When the target inspection application scenario is an actual inspection that provides remote business guidance, the actual inspection personnel and the remote inspection business guidance experts can complete the actual inspection task of providing remote business guidance by controlling the smart wearable device and the virtual driving module respectively.

[0072] In one feasible implementation, during the controlled execution of the inspection task of the new energy power station by the second inspection equipment, the external situation is monitored in real time. When encountering severe weather such as rain, snow, hail, or strong winds, considering that the on-site inspection personnel have more information about the surrounding environment, the remote inspection mode can be exited and the second inspection equipment can be controlled locally using only smart wearable devices, or the second inspection equipment can be commanded to perform automatic return.

[0073] In one feasible implementation, a second QR code can be set on some equipment in the new energy power station to obtain the inspection operation information of the key inspection nodes corresponding to the key equipment, including the inspection node type, actual location, optimal collection point, optimal collection sequence and operation process; the location and data collection requirements of the key inspection nodes of different equipment are different, and the camera module of the second inspection equipment can be used to scan the QR code with pre-set related information to obtain the inspection information.

[0074] In one feasible implementation, when the second inspection device is a drone and it has moved to the vicinity of a key inspection node, specifically when the straight-line distance is less than a preset value, a high-precision control mode can be activated. The drone can adjust its flight direction, pitch angle, and flight speed based on the pitch and rotation angles of the smart wearable device and the forward, backward, and speed adjustment buttons set on the smart wearable device. Its flight speed is very slow to avoid collisions and missing key inspection nodes. After the position is qualified, inspection information is collected and transmitted.

[0075] Smart wearable devices are equipped with gyroscopes that can detect their own rotation and pitch angles. The flight direction and pitch angle of a drone can be controlled based on the rotation and pitch angles detected by the gyroscope.

[0076] In one feasible implementation, the centralized monitoring method for new energy power stations using multi-source heterogeneous analysis further includes: Step 6: Setting a third QR code on some new energy power station equipment, and smart wearable devices and automatic inspection devices can scan the third QR code and establish a connection with the local fast communication module of the new energy power station equipment to transmit data.

[0077] The local high-speed communication module is specifically a wireless WLAN module for new energy power station equipment; by scanning the third QR code, smart wearable devices and automatic inspection equipment can automatically connect to and utilize the wireless WLAN module for high-speed data transmission, avoiding the loss of massive amounts of data and transmission lag.

[0078] The automatic inspection equipment can use the local high-speed communication module to quickly send the collected data to the smart wearable device and the virtual driving module. The transmission path is as follows: automatic inspection equipment - local high-speed communication module - network cable - virtual driving module, or automatic inspection equipment - local high-speed communication module - smart wearable device. Data transmission between the smart wearable device and the virtual driving module can also use the local high-speed communication module. The transmission path is as follows: smart wearable device - local high-speed communication module - network cable - virtual driving module. By reusing the communication module of the station equipment, the data transmission speed can be improved.

[0079] In one feasible implementation, after the key inspection node information of the device is collected, the obtained inspection node information can be quickly uploaded and sent through a local fast communication module.

[0080] In one feasible implementation, the local fast communication module can also be other communication modules capable of building a local area network.

[0081] In one feasible implementation, the centralized monitoring method for new energy power plants utilizing multi-source heterogeneous analysis further includes: Step 7: When a new energy power station operates based on the coordinated operation of different energy sources, these different energy sources may include wind power, hydropower, and photovoltaic power generation. The output characteristics of each energy source are utilized to complement each other, and energy storage devices are used for peak shaving and valley filling to improve the stability of power generation. Specifically, this includes: Step 71: Periodically acquire information on wind direction, wind speed, temperature, and humidity of the wind power generation operating environment to determine the current output power of the wind power generation and its change value.
