Description

Technical Field

[0001] The present invention relates to a lightning-based information providing system that can provide various types of information according to lightning conditions.

Background Art

[0002] As a technology for estimating the lightning charge amount and position at the time of lightning strike, a lightning location evaluation system (Lightning Location Systems: LLS) is used. LLS is a technology that measures the temporal changes in the electric field and magnetic field associated with lightning strikes and extracts the position and time of lightning strikes.

[0003] LLS is composed of, for example, measuring means for detecting electromagnetic waves generated by lightning strikes with a loop antenna and measuring the azimuth of lightning strikes and the peak value of the magnetic field (peak value of current), and analysis means for obtaining the lightning strike position and lightning current value based on the data observed by the measuring means.

[0004] By using LLS, it is possible to accurately identify towers, transmission lines, etc. that are at risk of damage due to lightning strikes, and quickly and appropriately perform maintenance, repair, etc. of equipment owned by power companies, etc., and restoration of infrastructure damage due to lightning strikes.

[0005] In recent years, in LLS, it has become possible to grasp lightning parameters (lightning properties) such as lightning strike position evaluation, charge amount, current peak value, and current steepness in a wide area and in detail. Therefore, in addition to performing maintenance of transmission facilities of power companies, etc. based on the lightning information obtained by LLS, it is considered possible to grasp the influence of lightning on the construction and maintenance of various equipment.

Brief Description of the Drawings

[0024] [Figure 1]This is a block diagram of a system for providing information based on lightning. [Figure 2] This graph illustrates the conditions of lightning strikes. [Figure 3] This is a block diagram illustrating the means for providing lightning information. [Figure 4] This is a schematic diagram of the business establishment. [Figure 5] This is a schematic diagram of another example of a business establishment. [Modes for carrying out the invention]

[0025] Figure 1 shows the block configuration of a lightning-based information provision system according to one embodiment of the present invention, Figure 2 shows an explanation of current waves illustrating the situation of a lightning strike, Figure 3 shows an explanation of the lightning information provision means, and Figure 4 shows a schematic configuration illustrating the effects of lightning on signal and communication lines in a business establishment and the effects of lightning on equipment connected to signal and communication lines.

[0026] As shown in Figure 1, the lightning-based information provision system includes a lightning parameter derivation means 1 that receives lightning conditions (including location and position) obtained from a Lightning Location Systems (LLS) and derives lightning parameters based on the input conditions. The lightning parameters derived by the lightning parameter derivation means 1 are sent to the lightning information provision means 2, and information on the impact corresponding to the lightning parameters is provided to an external business establishment 3 (for example, a power plant).

[0027] Furthermore, information on the effects according to the lightning parameters will be provided as needed to locations other than Business Site 3.

[0028] In the current wave shown in Figure 2, the charge amount B, which is the inner region of the waveform; the current peak value I, which is the maximum value of the current wave; the current steepness S, which is the slope of the change in the rising current; the current duration T, which is the current generation time; and the incident angle θ of the lightning strike are derived as lightning parameters by the lightning parameter derivation means 1 and are provided as information by the lightning information provision means 2.

[0029] Lightning parameters include the angle of incidence θ of the lightning strike and may include at least one of the following: charge amount B, current peak value I, current gradient S, and current duration T. The lightning strike location is determined as information from the lightning information provision means 2, and the lightning parameters, including the lightning strike location, are sent to the equipment information function 4.

[0030] As shown in Figure 3, the equipment information function 4 stores information about the equipment at each business site 3, including the status of the equipment at each business site 3, the history of lightning strikes at each business site 3, and the history of damage caused by lightning strikes. When lightning parameters, including the location of the lightning strike, are sent to the equipment information function 4, the business site 3 corresponding to the location of the lightning strike is identified.

[0031] The information (lightning parameters) of the identified business establishment 3 is sent to the impact assessment function 5, which determines the impact of lightning on the equipment at the identified business establishment 3. The information on the impact of lightning on the equipment at business establishment 3, as determined by the impact assessment function 5, is provided to the identified business establishment 3.

[0032] The Impact Assessment Function 5 receives information on the frequency of past lightning strikes (frequency information), and the Impact Assessment Function 5 takes this history of lightning strikes into account to determine the impact on the equipment. In other words, based on the history of damage from past lightning strikes, the impact of the current lightning strike on the equipment is determined, the extent of the damage to the equipment is derived, and information on the extent of the damage is provided. Furthermore, maintenance information appropriate to the impact of the lightning strike is provided for the damaged equipment.

[0033] Based on the information provided, facility 3 will assess the extent of damage to the equipment according to the standards, as well as the degree of damage to the equipment.

[0034] Specifically, the impact determination function 5 of the lightning information provision means 2 provides information regarding the impact of lightning parameters, including the impact of lightning on signal and communication lines 11 at the business premises 3 where the lightning struck, and the impact of lightning on equipment 12 such as control equipment connected to the signal and communication lines.

[0035] In other words, as shown in Figure 4, based on the location of the lightning strike, the charge amount B, current peak value I, current intensity S, current duration T, and lightning incident angle θ are derived, and the effects of the lightning on signal / communication lines 11a, 11b, 11c, and 11d (effects of disconnection / damage) are determined according to the lightning parameters and the specifications of the signal / communication lines 11. Then, based on the effects of the lightning on signal / communication lines 11a, 11b, 11c, and 11d, the effects of the lightning on equipment 12A, 12B, 12C, and 12D connected to signal / communication lines 11 (presence or absence of damage, and the extent of damage) are determined.

[0036] Specifically, the magnitude of the impact on the signal / communication line 11 can be determined by the amount of charge B, the peak current value I, the current gradient S, and the current duration T, and the location where the signal / communication line 11 and the equipment 12 are most affected can be determined by the angle of incidence of the lightning strike θ.

[0037] For example, if the lightning strike incidence angle θ is less than 90 degrees, the effect of the radiated electromagnetic field will be greater on signal / communication lines 11a and 11b, and the effects of disconnection or damage to signal / communication lines 11a and 11b can be determined, as can the presence or absence of damage to equipment 12A and 12B (12C) and the extent of the damage.

[0038] Based on the effects of lightning on signal and communication lines 11a, 11b, 11c, and 11d (effects of disconnection and damage), this provides information on disconnections and damage to signal and communication lines 11a, 11b, 11c, and 11d, as well as maintenance information related to these effects.

[0039] For example, based on the effects of lightning on equipment 12A, 12B, 12C, and 12D connected to signal / communication lines 11a, 11b, 11c, and 11d (presence or absence of damage, and the extent of the damage), information on whether equipment 12A, 12B, 12C, and 12D is damaged, information on the damage, and maintenance information related to the damage are provided. Specifically, in response to disconnections or damage to signal / communication lines 11a, 11b, 11c, and 11d, maintenance information such as replacement, overhaul, and operational checks for equipment 12A, 12B, 12C, and 12D is provided.

[0040] The lightning-based information provision system is linked to multiple business sites 3. Based on the impact of lightning strikes on a specific business site 3, it can provide information on the risk of damage to any business site 3 (for example, a power plant with the same configuration) assuming a similar lightning strike occurs. In this case, frequency information can be taken into account, so the extent of damage to equipment can be evaluated in relation to the frequency of lightning strikes.

[0041] Furthermore, by using frequency information, it is possible to understand the impact of lightning strikes on the new business site 3, assuming similar lightning strikes occur at the planned construction site for business site 3, and provide this information to the business operator.

[0042] Based on Figure 5, another example of a business establishment will be explained. An example of providing information to a business establishment (operator) 21 that manages multiple fuel supply facilities (for example, electric vehicle charging stations: EV stations) will be given.

[0043] As shown in the figure, the business establishment 21 manages multiple EV stations 22A, 22B, 22C, 22D, 22E, 22F, etc., over a wide area (for example, at the prefectural or regional level). For example, if EV station 22A is struck by lightning, the lightning-based information provision system of the present invention (this system) will, similar to the case of the power plant described above, determine whether or not there is damage to the equipment and provide information about any damage. The information on the impact of the lightning strike on EV station 22A, as determined by this system, is managed by the lightning information provision means 2 (see Figures 1 and 3).

[0044] This system allows for the assessment of similar lightning strikes affecting other EV stations 22 (such as the extent of equipment damage and the types of damaged equipment), and the assessed information is provided to the business office 21.

[0045] By incorporating frequency information, this system can evaluate the extent of equipment damage caused by lightning strikes, etc., assuming that other EV stations 22 with the same configuration are struck by lightning under the same conditions at the frequency indicated by the frequency information.

[0046] Furthermore, when constructing similar EV stations in the future, this system can be used to evaluate the risk of lightning strikes, assuming that lightning strikes occur at the same frequency as indicated by the frequency information, and provide this information to the business 21.

[0047] The above-described embodiment illustrates the application of this system to a business establishment (operator) 21 that manages an EV station 22, which is an electric vehicle charging station. However, this system can also be applied to business establishments that manage facilities that supply other fuels, such as hydrogen supply stations and gas stations. Furthermore, it is possible to apply this system to a business establishment that manages multiple identical types of business facilities.

[0048] Furthermore, this system can be applied to businesses that manage individual home meters, such as gas and water companies, to provide them with information on the impact of lightning on each individual meter. When installing similar individual home meters, this system can be used to evaluate and provide information to businesses about the risk of lightning strikes, assuming that lightning strikes occur at the same frequency and under the same conditions as indicated by the frequency information. Based on this information, businesses can select the specifications of meter equipment when building new houses in residential developments, etc.

[0049] In addition to the above, it is possible to provide information on lightning parameters obtained by the lightning information provision means 2 to various businesses, etc., in areas prone to lightning strikes, taking frequency information into account. In this case, based on the provided information, businesses can take into account the effects of lightning when developing infrastructure or managing business risks. For example, it is also possible to provide information on the effects of lightning on alarms in individual homes to businesses that operate disaster prevention systems.

[0050] The aforementioned lightning-based information provision system can provide external information on lightning obtained from Lightning Location Systems (LLS). Specifically, it can provide information on the impact of lightning, such as the impact on equipment or lightning information for a specific area. [Industrial applicability]

[0051] This invention can be used in industrial fields for systems that provide information based on lightning. [Explanation of symbols]
