Such systems are suitable for large-scale and large-scale lightning monitoring and early warning. Local thunderstorms come quickly, are sudden, and cause great harm. There is currently no means to accurately predict where and when short-term thunderstorms will occur. Such local thunderstorms are very harmful to densely populated areas and special industries, especially to flammable and explosive places, such as power substations and other power facilities.

[0003] Moreover, the existing thunderstorm warning technology applied to the electrical system is carried out at a single point, that is, an independent lightning warning device, which fails to build a wide area network lightning warning system, cannot centrally integrate all the information resources in the regional monitoring system, and the power system warning monitoring information archive is difficult to organize. In addition, the existing warning system fails to build an emergency protection module linked to the power system, and only relies on alert manpower for protection, which is too inefficient.

[0036] In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention is further described in conjunction with the accompanying drawings of the specification.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] See also Figure 1 As shown, the present invention provides a power system wide area network early warning and protection system based on quantum radar, including: a plurality of node monitoring modules 100, a remote transmission module 200 and a central processing switchboard 300. The plurality of node monitoring modules 100 are distributed around facilities that need to be monitored for lightning in the power system, such as around substations, and the remote transmission module 200 is used to transmit the detection electrical signals output by the plurality of node monitoring modules 100. The central processing switchboard 300 receives the detection electrical signals transmitted by the remote transmission module 200, and performs data processing on the detection electrical signals to perform lightning early warning.

[0039] See also Figure 2 As shown, in one embodiment of the present invention, each node monitoring module 100 uses a quantum laser radar 111 to perform lightning monitoring with high temporal and spatial resolution. Specifically, each node monitoring module 100 includes a laser module 110, a telescope transceiver module 120, and a detection processing module 130, wherein the laser module 110 includes a quantum laser radar 111 and an amplifier 112, and the detection processing module 130 includes a single photon detector 131 and a signal processor 132.

[0040] In this embodiment, the quantum laser radar 111 emits an invisible infrared laser, the amplifier 112 is used to amplify the energy of the infrared laser, and the laser sending part of the telescope transceiver module 120 emits the laser emitted by the laser module 110 into the atmosphere. The laser acts in the atmosphere to produce backscattered light, and the backscattered light returns to the scattered light receiving part of the telescope transceiver module 120 through the original path.

[0041] The single photon detector 131 is used to receive the backscattered light received by the telescope transceiver module 120 and convert it into a detection electrical signal and output it to the signal processor 132. The signal processor 132 edits and processes the electrical signal to convert it into a state that meets the transmission requirements of the remote transmission module 200 to the central processing unit 300.

[0042] In this embodiment, the 1550nm laser light source emitted by the quantum laser radar 111 is used as the transmission signal, and the 1550nm invisible infrared laser is emitted into the atmosphere, and reacts with the molecules, aerosol particles, clouds, precipitation, smoke, etc. in the atmosphere. The backscattered light generated by it is returned to the scattered light receiving part of the telescope transceiver module 120 through the original path in the reverse direction. The received backscattered light is detected by the single photon detector 131, and data analysis and processing are performed to invert the atmospheric parameter information at different positions on the atmospheric path, such as the atmospheric extinction coefficient, depolarization degree, echo intensity, etc. Compared with traditional radars, it has a higher signal-to-noise ratio when the laser energy is low, which effectively makes up for the problem that the existing system cannot quickly measure pollution sources in a large-scale area in three-dimensional space and at high altitude levels.

[0043] In this embodiment, in addition, the photoelectric detector has low detection efficiency for long-wavelength light and has large noise. For this reason, we further improve the acquisition part of the quantum laser radar. The detection processing module 130 also includes a frequency multiplier 133. The input end of the frequency multiplier 133 is connected to the scattered light receiving part of the telescope transceiver module 120, and the output end is connected to the single photon detector 131. That is, before the backscattered light enters the single photon detector 131, a wavelength conversion is performed, and the wavelength can be shortened based on the anti-Stokes effect. The backscattered light of 1550nm is changed to 775nm light through it, and then sensed by the single photon detector 131, which can improve the detection efficiency.

[0044] In this embodiment, each node monitoring module 100 further includes a pan-tilt 141 and a water cooling module 141, wherein the pan-tilt 141 is in communication with the controller in the detection processing module 130 and the telescope transceiver module 120, and the controller sends a control signal to the pan-tilt 141, and the pan-tilt 141 controls the lens rotation of the telescope transceiver module 120 for multi-angle detection. The water cooling module 141 is connected to the controller and is used to cool the laser module 110 and the telescope transceiver module 120.

[0045] See also Figure 1 As shown, in one embodiment of the present invention, the remote transmission module 200 can be wired transmission, wireless transmission, optical fiber transmission, power line communication, etc.

[0046] See also Figures 1 to 3As shown, in one embodiment of the present invention, the central processing unit 300 includes at least one lightning warning module 310. The lightning warning module 310 accurately knows the cloud information at each node monitoring module 100 according to the detected electrical signal, and gives a lightning warning signal. The lightning warning module 310 includes a lightning real-time monitoring submodule 311, a lightning approaching warning submodule 312, and a lightning historical data statistics query submodule 313.

[0047] The lightning real-time monitoring submodule 311 is used to analyze and calculate the changes in the surrounding atmospheric electric field before and after the lightning occurs, the time, location, intensity, polarity and number of return strokes of the lightning, realize the analysis and display of the spectrum and curve of the radar data, and generate the time-space analysis diagram of the radar data.

[0048] The lightning approach warning submodule 312 is used to monitor how long it will take for lightning activity to occur in the area in the future, and define the warning level and duration according to the probability of lightning activity, and generate warning information on the lightning warning level, lightning warning time, warning area, and warning cancellation.

[0049] The lightning historical data statistical query submodule 313 has the functions of querying lightning warning information and statistical analysis in the coverage area, and is used to provide data support for later lightning accident investigation and regional lightning activity characteristic analysis. Among them, the lightning historical data statistical query submodule 313 includes two subsystems: a convective weather big data sample pre-processing subsystem and an artificial intelligence algorithm extrapolation subsystem.

[0050] 1. Convective weather big data sample pre-processing subsystem

[0051] Perform quality control and preprocessing on radar data to generate valid radar data for use in building intelligent extrapolation models. Calculate the maximum and minimum echo values ​​at a single moment, and other characteristic quantities that reflect echo intensity, screen severe convective weather processes, and create corresponding convective weather data sets for use in extrapolation models.

[0052] 2. Artificial Intelligence Algorithm Extrapolation Subsystem

[0053] For a specific weather category, one or more of the most suitable extrapolation models are selected from a variety of deep learning algorithms to construct a time series change model of radar echoes, and the radar echoes at the next moment are extrapolated and predicted.

[0054] See also Figures 1 to 4As shown, in one embodiment of the present invention, each node monitoring module 100 includes a node automatic protection module 150; and the central processing switchboard 300 is connected to the node automatic protection module 150 in communication, and the node automatic protection module 150 can be remotely controlled. When the lightning warning module 310 sends a lightning warning signal, the node automatic protection module 150 receives the lightning warning signal and performs a protection operation according to the lightning warning level. Among them, the protection operation includes: according to the lightning warning level, outputting a protection instruction (I / 0 signal), the protection instruction can automatically cut off the power supply system of some equipment or switch to UPS power supply, and isolate the damage of lightning from the power line to important equipment; and using it to issue a three-level sound and light alarm function, when the lightning warning is lifted, the city power supply is automatically restored or the sound and light alarm is lifted, and the process of actively avoiding thunderstorms is completed. It can also be notified to relevant personnel in the form of text messages, and notify the management personnel to handle the emergency in time, so that the lightning protection of the electric field is more active and intelligent.

[0055] In this embodiment, a third-level warning can be issued for the approach of lightning in the area 15-30 minutes in advance. Before thunderstorm clouds appear, there is usually a period of time when the clouds gradually increase in height and the cloud shape gradually becomes more complex. At this time, quantum laser radar can be used to detect changes in cloud layer and cloud shape to predict weather changes in a short period of time. If the thunderstorm cloud moves faster, has a higher shape and has obvious downdrafts, it means that severe convective weather phenomena may occur. By identifying convective clouds where lightning may occur through atmospheric pollution monitoring radar, some macroscopic characteristics of charged particles in the cloud can be better observed, which plays a certain role in lightning warning.

[0056] In this embodiment, when the laser emitted by the quantum laser radar 111 is transmitted in the atmosphere, it is attenuated by the atmosphere on the transmission path, mainly from the extinction of atmospheric particles and air molecules. At the same time, a part of it returns along the original path and is attenuated by the atmosphere on the transmission path again, and is finally received by the single photon detector 131. On the one hand, it can be used to detect the concentration distribution and shape characteristics of aerosols on the path, and is used as a tool for semi-qualitative monitoring of pollutants. On the other hand, it can invert cloud information and determine the cloud bottom height by measuring the time required for a laser pulse to be emitted from the laser emitting part of the telescope transceiver module 120, reach the cloud bottom, and then reflect to the scattered light receiving part of the telescope transceiver module 120. The quantum laser radar 111 emits laser pulses vertically upward. If there are clouds above the transmitter, strong backscattering will occur. By measuring and calculating the signal received by the scattered light receiving part of the telescope transceiver module 120, the cloud height can be determined. By time statistics or scanning the light beam, cloud height and multi-layer cloud structure and other cloud information can be obtained.

[0057] In one embodiment of the present invention, the function of monitoring air pollution can also be added to the power system wide area network early warning and protection system. According to the daily scanning spectrum of the quantum laser radar 111, it can be used to detect the distribution of air pollutants above and around important power energy sites such as power stations and substations. The distribution of aerosol pollution within 5km around the air quality monitoring station can be quickly locked, providing a means of troubleshooting abnormal data at air quality monitoring points and guiding refined management and control.

[0058] For details, please refer to Figures 1 to 3 As shown, in one embodiment of the present invention, the central processing switchboard 300 includes an air pollution early warning module 320. The aerosol information at each node monitoring module 100 is obtained according to the detected electrical signal, and an air pollution monitoring signal is given. When the air pollution monitoring signal is at a normal level, it is transmitted to the air monitoring display device in real time or in a scheduled manner. When the air pollution monitoring signal is abnormal, an active early warning instruction is issued, such as contacting the set person in charge by SMS or telephone broadcast, so that he or she is aware of it and takes corresponding treatment measures.

[0059] See also Figures 1 to 3 As shown, the present invention also provides a power system wide area network early warning protection method based on quantum radar, including several node monitoring modules 100, a remote transmission module 200 and a central processing switchboard 300.

[0060] The remote transmission module 200 is used to transmit the detection electrical signals output by several node monitoring modules 100; the central processing unit 300 receives the detection electrical signals transmitted by the remote transmission module 200, and performs data processing on the detection electrical signals to provide lightning warning.

[0061] Each node monitoring module 100 includes: a laser module 110 , a telescope transceiver module 120 , a single photon detector 131 and a signal processor 132 .

[0062] The laser module 110 emits a laser, and the laser transmitting part of the telescope transceiver module 120 injects the laser emitted by the laser module 110 into the atmosphere. The laser acts in the atmosphere to generate backscattered light, and the backscattered light returns to the scattered light receiving part of the telescope transceiver module 120 through the original path in the reverse direction.

[0063] The single photon detector 131 is used to receive the backscattered light received by the telescope transceiver module 120 and convert it into a detection electrical signal and output it to the signal processor 132. The signal processor 132 edits and processes the electrical signal to convert it into a state that meets the transmission requirements of the remote transmission module 200 to the central processing unit 300.
