Technical Field

[0001] The present application relates to the technical field of water conservancy engineering, and in particular to a hydropower station safety monitoring method and related equipment. Background Art

[0002] As an important clean energy power generation method, hydropower station occupies a key position in the global energy structure. It uses the energy of water flow to convert into electrical energy, and has significant advantages such as clean, renewable, and relatively low operating costs. With the increasing attention paid to environmental protection and sustainable development around the world, the construction and operation of hydropower stations have received widespread attention and development.

[0003] In order to improve the safety of hydropower stations, more and more hydropower stations have begun to conduct real-time monitoring of relevant equipment, water volume and dam conditions, which has played an important role in reducing the safety risks of hydropower stations. However, most hydropower stations only focus on monitoring factors that directly affect the safety of hydropower stations, such as hydropower station equipment, dams and water volume, while ignoring the impact of other potential factors on the safety of hydropower stations. This makes the accuracy of hydropower station safety monitoring fail to meet user needs, which in turn leads to higher safety risks in hydropower stations. Summary of the invention

[0090] In a first aspect, the present application discloses a method for safety monitoring of a hydropower station.

[0091] Reference Figure 1 , a hydropower station safety monitoring method, comprising steps S101 to S107:

[0092] Step S101: Acquire water quality information of the water body where the target hydropower station is located.

[0093] Specifically, the target hydropower station is a hydropower station that needs to be monitored for safety; water quality information includes physical information, chemical information, biological information, etc. In this embodiment, a large number of different types of sensors and cameras are installed in the water body where the target hydropower station is located to collect water quality information.

[0094] Step S102: Determine whether the water quality information meets the preset water quality requirements.

[0095] Specifically, the preset water quality requirements are pre-set criteria for determining whether there are safety risks based on water quality information. In this embodiment, the preset water quality requirements vary depending on the water quality information, including preset physical requirements, preset chemical requirements, and preset biological requirements.

[0096] Step S103: If the water quality information does not meet the preset water quality requirements, abnormal information is obtained.

[0097] Specifically, in this embodiment, if the water quality information does not meet the preset water quality requirements, it indicates that there is a problem with the water quality. In order to further deal with the water quality problem, abnormal information is obtained, where the abnormal information is the water quality information with problems. For example, if there is a problem with the physical information in the water quality information, the corresponding physical information is marked as abnormal information.

[0098] Step S104: Based on the abnormal information, the water body in the water area where the target hydropower station is located is processed.

[0099] Specifically, in this embodiment, the water body in the water area where the target hydropower station is located is processed according to the specific circumstances of the abnormal information; for example, when the water turbidity in the water quality information is too high and does not meet the preset water quality requirements, the corresponding water turbidity in the water quality information is marked as abnormal information, and the water body in the water area is processed according to the water turbidity.

[0100] Step S105: If the water quality information meets the preset water quality requirements, the change of the water quality information is obtained.

[0101] Specifically, in this embodiment, when the water quality information meets the preset water quality requirements, it indicates that there is no problem with the water quality at the current time node. Based on the water quality information in the recent period, the changes in the water quality information are analyzed, and the changes include the change amplitude and change rate of the water quality information within a certain time interval.

[0102] Step S106: Based on the changes, determine whether the target hydropower station has potential risks.

[0103] Specifically, in this embodiment, a potential risk is a risk that does not exist currently but can be inferred to have a high probability of occurring based on changes.

[0104] Step S107: If there is a potential risk in the target hydropower station, the potential risk is processed.

[0105] Specifically, in this embodiment, when there is a potential risk, a corresponding treatment plan is generated for the potential risk to reduce the probability of the potential risk becoming an actual risk, thereby reducing the safety risk of the hydropower station.

[0106] The hydropower station safety monitoring method provided in this embodiment first obtains water quality information and determines whether the water quality information meets the preset water quality requirements. If not, it indicates that there is a water quality problem in the water body in the water area where the target hydropower station is located. If it is not handled in time, it will also have an adverse impact on the safety of the hydropower station. In order to solve the safety hazard, further abnormal information is obtained, and the water body in the water area where the target hydropower station is located is handled according to the abnormal information.

[0107] If it is satisfied, it indicates that there is no water quality problem in the water body where the target hydropower station is located. In order to further increase the accuracy of safety monitoring of the hydropower station, further obtain the changes in water quality information, and judge whether there is potential risk in the target hydropower station based on the changes. If so, deal with the potential risk.

[0108] By using the water quality information of the water body in the water area where the target hydropower station is located as one of the monitoring information to determine whether the target hydropower station has safety risks, it helps to make the monitoring objects of the hydropower station safety monitoring more comprehensive, thereby helping to improve the accuracy of the hydropower station safety monitoring, and further helping to reduce the safety risks of the hydropower station; in addition, when the water body in the water area where the target hydropower station is located has a potential risk of deterioration in water quality in the future, the potential risk can be dealt with in advance, which helps to reduce the probability of potential risks turning into actual risks, thereby helping to further reduce the safety risks of the hydropower station caused by water quality problems.

[0109] Reference Figure 2 In one implementation of this embodiment, step S102 determines whether the water quality information meets the preset water quality requirements, including steps S201 to S204:

[0110] Step S201: Obtain physical indicators, chemical indicators and biological indicators of water bodies in the water area.

[0111] Specifically, in this embodiment, physical indicators are indicators related to the physical properties of water bodies in water areas, including water turbidity, water chromaticity, and water temperature; chemical indicators are indicators related to the chemical properties of water bodies in water areas, including water pH, water conductivity, and water substance content; biological indicators are indicators related to the biological properties of water bodies in water areas, including algae coverage, unit bacterial count, and biodiversity.

[0112] Step S202: respectively judging whether the physical index meets the preset physical requirements, whether the chemical index meets the preset chemical requirements, and whether the biological index meets the preset biological requirements, and generating corresponding first judgment results, second judgment results, and third judgment results.

[0113] Specifically, the preset physical requirement is a preset judgment standard for judging whether the physical index meets the preset water quality requirement; the preset chemical requirement is a preset judgment standard for judging whether the chemical index meets the preset water quality requirement; the preset biological requirement is a preset judgment standard for judging whether the biological index meets the preset water quality requirement; the first judgment result is the judgment result of judging whether the physical index meets the preset physical requirement, the second judgment result is the judgment result of judging whether the chemical index meets the preset chemical requirement, and the third judgment result is the judgment result of judging whether the biological index meets the preset biological requirement. In this embodiment, the judgment results include yes and no.

[0114] Step S203: Determine whether at least one of the first judgment result, the second judgment result, and the third judgment result does not meet the corresponding result requirement.

[0115] Specifically, the result requirement is a specified judgment result. In this embodiment, the result requirement is set to the judgment result being yes.

[0116] Step S204: If there is at least one result that does not meet the corresponding requirement, it is determined that the water quality information does not meet the preset water quality requirement.

[0117] Specifically, in this embodiment, as long as any one or more judgment results do not meet the corresponding result requirements, it indicates that there is a problem with the water quality, and therefore it is determined that the water quality information does not meet the preset water quality requirements. Only when all judgment results meet the corresponding result requirements, it is indicated that there is no problem with the water quality, and therefore it is determined that the water quality information meets the preset water quality requirements.

[0118] The hydropower station safety monitoring method provided in this embodiment obtains the physical indicators, chemical indicators and biological indicators of the water body in the water area, and compares them with the corresponding preset physical requirements, preset chemical requirements and preset biological requirements to generate corresponding first judgment results, second judgment results and third judgment results. When at least one of the three judgment results does not meet the corresponding result requirements, that is, when at least one of the three judgment results is no, it indicates that there is a problem with the water quality of the water body in the water area, and therefore it is determined that the water quality information does not meet the preset water quality requirements; by analyzing the physical indicators, chemical indicators and biological indicators in multiple dimensions, the judgment factors are more comprehensive and the judgment results are therefore more accurate.

[0119] Reference Figure 3 In one implementation of this embodiment, determining whether the physical indicator does not meet the preset physical requirements includes steps S301 to S307:

[0120] Step S301: Determine whether the turbidity of the water body meets the turbidity requirement.

[0121] Specifically, water turbidity refers to the degree to which water becomes turbid due to the presence of suspended particles in the water, such as silt, clay, organic matter, microorganisms, etc. The higher the water turbidity, the more suspended particles are contained in the water and the more turbid the water is. The more silt there is, the greater the wear on the turbine and the greater the water flow resistance, so the power generation efficiency is lower. It is also easy to reduce the effective storage capacity of the reservoir, causing the water to overflow easily, posing a higher risk to the hydropower station. Therefore, it is prioritized to determine whether the water turbidity meets the turbidity requirements.

[0122] In this embodiment, a plurality of collection points are distributed in the waters where the target hydropower station is located for collecting water samples. The collected water samples can be compared with standard turbidity solutions to obtain the water turbidity of the water samples. Alternatively, a drone equipped with a high-resolution camera or a multi-spectral sensor can fly at a low altitude to photograph and collect data on the water in the collection point area. The color, texture and other features of the water can be extracted through image processing and analysis techniques to estimate the water turbidity in the sampling point area. The turbidity requirement is a pre-set judgment standard for determining whether the water turbidity meets the preset physical requirements. In this embodiment, the turbidity requirement can be that the water turbidity is less than 10NTU.

[0123] Step S302: If the turbidity of the water body does not meet the turbidity requirement, it is determined that the physical index does not meet the preset physical requirement.

[0124] Step S303: If the turbidity of the water body meets the turbidity requirement, determine whether the chromaticity of the water body meets the chromaticity requirement.

[0125] Specifically, the chromaticity of water mainly reflects the color characteristics of colored substances present in water, such as dissolved organic matter, suspended particles, algae, etc. In this embodiment, standard solutions with different chromaticities (0-500 degrees) can be prepared first, and the collected water samples are compared with standard solutions with different chromaticities to finally match the standard solution closest to the color of the water sample. The chromaticity of the standard solution is the chromaticity of the water sample to be tested. The chromaticity of water can also be determined by spectrophotometry or other methods; the chromaticity requirement can be that the chromaticity of the water is less than 15 degrees.

[0126] Step S304: If the chromaticity of the water body does not meet the chromaticity requirement, it is determined that the physical index does not meet the preset physical requirement.

[0127] Step S305: If the chromaticity of the water body meets the chromaticity requirement, determine whether the temperature of the water body meets the temperature requirement.

[0128] Specifically, in this embodiment, the water body temperature, that is, the water temperature of the water body in the water area, can be obtained by a temperature sensor. The temperature requirement varies according to the location of the hydropower station. In this embodiment, the temperature requirement is set to a water body temperature between 15°C and 25°C.

[0129] Step S306: If the water temperature does not meet the temperature requirement, it is determined that the physical index does not meet the preset physical requirement.

[0130] Step S307: If the water temperature meets the temperature requirement, it is determined that the physical index meets the preset physical requirement.

[0131] It is worth noting that, in this embodiment, when multiple groups of data are collected at multiple collection points, the average data of the multiple groups of data can be compared with the corresponding requirements, or the data of each collection point can be compared with the corresponding requirements respectively, and then the corresponding ratio can be set according to the number of collection points. For example, when the data collected by more than 80% of the collection points meet the corresponding requirements, the data is considered to meet the corresponding requirements.

[0132] The hydropower station safety monitoring method provided in this embodiment first determines whether the turbidity of the water body meets the turbidity requirements. If not, it indicates that the turbidity of the water body is high and there are many suspended particles in the water body, so it is determined that the physical indicators do not meet the preset physical requirements; if it is satisfied, it is further determined whether the chromaticity of the water body meets the chromaticity requirements. If not, it indicates that the chromaticity of the water body is too high, so it is determined that the physical indicators do not meet the preset physical requirements; if it is satisfied, it is further determined whether the temperature of the water body meets the temperature requirements. If not, it indicates that the water temperature is not within the normal temperature range, so it is determined that the physical indicators do not meet the preset physical requirements; if it is satisfied, it indicates that the turbidity of the water body, the chromaticity of the water and soil, and the water and soil temperature all meet the corresponding requirements, so it is determined that the physical indicators meet the preset physical requirements; by analyzing and judging different physical indicators, it is determined whether the physical indicators of the water body in the water area meet the preset physical requirements.

[0133] Reference Figure 4 In one implementation of this embodiment, determining whether the chemical index does not meet the preset chemical requirements includes steps S401 to S407:

[0134] Step S401: Determine whether the pH of the water body meets the pH requirement.

[0135] Specifically, the pH value of water is an indicator to measure the strength of the acidity and alkalinity of water. pH detectors can be set at multiple collection points to monitor the pH value of water. In this embodiment, the pH value requirement can be set to a pH value between 6.5 and 8.0.

[0136] Step S402: If the pH of the water body does not meet the pH requirement, it is determined that the chemical index does not meet the preset chemical requirement.

[0137] Step S403: If the pH of the water body meets the pH requirement, determine whether the conductivity of the water body meets the conductivity requirement.

[0138] Specifically, the water body conductivity, that is, the ability of the water body in the water area where the target hydropower station is located to conduct current, can be measured by a conductivity test instrument; in this embodiment, the conductivity requirement can be set to be between 100-300 μS / cm.

[0139] Step S404: If the water body conductivity does not meet the conductivity requirement, it is determined that the chemical index does not meet the preset chemical requirement.

[0140] Step S405: If the conductivity of the water body meets the conductivity requirement, it is determined whether the substance content of the water body meets the substance content requirement.

[0141] Specifically, the water body substance content, that is, the content of heavy metal substances contained in the water body of the water area, can be obtained by collecting water samples at multiple sampling points and then testing the water samples to obtain the heavy metal content of the corresponding area; in this embodiment, the substance content requirements can be set according to the drinking water standard, for example, lead (Pb) is generally required to be no more than 0.01 mg / L, mercury (Hg) is usually required to be no more than 0.001 mg / L, cadmium (Cd): generally no more than 0.005 mg / L, chromium (Cr): hexavalent chromium is required to be no more than 0.05 mg / L, etc.

[0142] Step S406: If the substance content of the water body does not meet the substance content requirement, it is determined that the chemical index does not meet the preset chemical requirement.

[0143] Step S407: If the substance content of the water body meets the substance content requirement, it is determined that the chemical index meets the preset chemical requirement.

[0144] The hydropower station safety monitoring method provided in the present embodiment first determines whether the pH of the water body meets the pH requirement. If not, it indicates that the pH of the water body is too high or too low, so it is determined that the chemical index does not meet the preset chemical requirement; if it is satisfied, it is further determined whether the conductivity of the water body meets the conductivity requirement. If not, it indicates that the conductivity of the water body is too high or too low, so it is determined that the chemical index does not meet the preset chemical requirement; if it is satisfied, it is further determined whether the material content of the water body meets the material content requirement. If not, it indicates that the heavy metal content of the water body is too high, so it is determined that the chemical index does not meet the preset chemical requirement; if it is satisfied, it indicates that the pH of the water body, the conductivity of the water body and the material content of the water body all meet the corresponding requirements, so it is determined that the chemical index meets the preset chemical requirement; by analyzing and judging different chemical indicators, it is determined whether the chemical index of the water body in the water area meets the preset chemical requirements.

[0145] Reference Figure 5 In one implementation of this embodiment, determining whether the biological indicator does not meet the preset biological requirement includes steps S501 to S507:

[0146] Step S501: Determine whether the algae coverage rate meets the coverage rate requirement.

[0147] Specifically, in this embodiment, the algae coverage rate refers to the ratio of the area covered by algae in the water area to the total area of ​​the water area. Multiple sampling points are set in the water area where the algae coverage rate needs to be measured. Sampling tools such as water samplers, plankton nets, etc. can be used to collect water samples and algae samples. At the same time, underwater photography, video equipment or direct underwater observation can be used to record the distribution and coverage area of ​​algae in the water body; the coverage rate requirement can be set to the algae coverage rate may be below 10%.

[0148] Step S502: If the algae coverage rate does not meet the coverage rate requirement, it is determined that the biological indicator does not meet the preset biological requirement.

[0149] Step S503: If the algae coverage rate meets the coverage rate requirement, it is determined whether the unit bacteria quantity exceeds a first quantity threshold.

[0150] Specifically, in this embodiment, the unit bacterial number is the number of bacteria present in a unit water body, and the unit bacterial number can be obtained by using a plate counting method or a microscope counting method or the like; the first number threshold can be set to 20,000 / ml.

[0151] Step S504: If the unit bacteria quantity exceeds the first quantity threshold, it is determined that the biological indicator does not meet the preset biological requirement.

[0152] Step S505: If the unit bacteria quantity does not exceed the first quantity threshold, it is determined whether the biodiversity meets the diversity requirement.

[0153] Specifically, in this embodiment, biodiversity includes the number of species and the number of organisms of different species, and diversity requirements include species number requirements and organism number requirements. Unit volume of water samples can be collected from multiple sampling points, and then the number of species and the number of organisms of different species in the water samples can be measured; in this embodiment, both the species number requirements and the organism number requirements can be set according to drinking water standards.

[0154] Step S506: If the biodiversity does not meet the diversity requirement, it is determined that the biological indicator does not meet the preset biological requirement.

[0155] Step S507: If the biodiversity meets the diversity requirement, it is determined that the biological indicator meets the preset biological requirement.

[0156] The hydropower station safety monitoring method provided in this embodiment first determines whether the algae coverage rate meets the coverage rate requirement. If not, it indicates that the algae coverage rate is too high, so it is determined that the biological index does not meet the preset biological requirement; if it is satisfied, it is further determined whether the unit bacteria count exceeds the first quantity threshold. If not, it indicates that the unit bacteria count is too large, so it is determined that the biological index does not meet the preset biological requirement; if it is satisfied, it is further determined whether the biodiversity meets the preset biological requirement. If not, it indicates that the biodiversity is too low, so it is determined that the biological index does not meet the preset biological requirement; if it is satisfied, it indicates that the algae coverage rate, the unit bacteria count and the biodiversity all meet the corresponding requirements, so it is determined that the biological index meets the preset biological requirement; by analyzing and judging different biological indicators, it is determined whether the biological indicators of the water body meet the preset biological requirements.

[0157] Reference Figure 6 In one implementation of this embodiment, if the number of unit bacteria does not exceed the first number threshold in step S505, determining whether the biodiversity meets the diversity requirement includes steps S601 to S608:

[0158] Step S601: If the unit bacteria quantity does not exceed the first quantity threshold, the species quantity in multiple unit sampling areas is obtained.

[0159] Specifically, the unit sampling area can be 100 cubic meters. In this embodiment, sonar or camera devices can be used to collect animals and plants in the sampling area to obtain the number of large species in the sampling area, and then collect the number of microorganisms in 1 cubic decimeter of water. The number of microorganisms is then proportionally amplified to obtain the final number of species.

[0160] Step S602: based on the number of species in different unit sampling areas, obtain the average number of species.

[0161] Specifically, in this embodiment, the average number of species is the average value of the number of species in a plurality of unit sampling areas.

[0162] Step S603: Determine whether the average number of species exceeds a preset number threshold.

[0163] Specifically, in this embodiment, the preset quantity threshold is a pre-set judgment standard for judging whether the average number of species meets the requirements.

[0164] Step S604: If the average number of species exceeds a preset number threshold, it is determined that the biodiversity meets the diversity requirement.

[0165] Step S605: If the average number of species does not exceed the preset number threshold, a number difference is obtained based on the average number of species and the preset number threshold.

[0166] Specifically, in this embodiment, the quantity difference is the difference obtained by subtracting a preset quantity threshold from the average species quantity.

[0167] Step S606: Determine whether the quantity difference is less than the difference threshold.

[0168] Specifically, in this embodiment, the difference threshold is a criterion for determining whether the quantity difference is too large.

[0169] Step S607: If the quantity difference is less than the difference threshold, it is determined whether the target new species appears in the water body of the water area where the target hydropower station is located.

[0170] Specifically, in this embodiment, the target new species is a species that has never appeared or has become extinct in the area where the target hydropower station is located and will not cause significant harm to the biodiversity in the area.

[0171] Step S608: If a target new species appears in the water body of the water area where the target hydropower station is located, it is determined that the biodiversity meets the diversity requirements.

[0172] The hydropower station safety monitoring method provided in the present embodiment obtains the average number of species based on the number of species in different unit sampling areas, and determines whether the average number of species exceeds a preset number threshold. If it exceeds, it indicates that the number of biological species in the sampling area is large and meets the diversity requirements; if it does not exceed, it indicates that the number of biological species in the sampling area is small. In order to determine whether the biodiversity in the area meets the diversity requirements, the number difference is further obtained, and it is determined whether the number difference is less than the difference threshold. If it is less than, it indicates that the average number of species is only slightly lower than the preset number threshold. It is further determined whether the target new species appears in the water body of the water area where the target hydropower station is located. If so, it indicates that the target new species appears in the water body of the water area. Therefore, the water quality environment in the water body of the water area is good, and therefore it is determined that the biodiversity meets the diversity requirements. By judging the biodiversity from multiple aspects, it helps to improve the accuracy of the judgment results, thereby reducing the safety risks of the hydropower station.

[0173] Reference Figure 7 In one implementation of this embodiment, if the water quality information meets the preset water quality requirements in step S105, obtaining the change of the water quality information includes steps S701 to S704:

[0174] Step S701: Based on the change situation, obtain the unit change rate of different water quality information.

[0175] Specifically, in this embodiment, the unit change rate is the change rate of the water quality information within a unit time, for example, within a day.

[0176] Step S702: Determine whether there is at least one unit change rate that exceeds the corresponding preset change rate threshold.

[0177] Specifically, in this embodiment, the preset change rate threshold value varies according to different water quality information, and is used to determine whether the water quality information undergoes a significant change within a unit time.

[0178] Step S703: If all unit change rates do not exceed the corresponding preset change rate thresholds, it is determined that there is no potential risk in the target hydropower station.

[0179] Step S704: If there is at least one unit change rate that exceeds the corresponding preset change rate threshold, it is determined that the target hydropower station has a potential risk.

[0180] The hydropower station safety monitoring method provided in the present embodiment obtains the unit change rate of different water quality information based on the change situation, and determines whether there is at least one unit change rate that exceeds the corresponding preset change rate threshold. If so, it indicates that there is a unit change rate that exceeds the preset change rate threshold, and there is a potential risk in the target hydropower station; if all unit change rates do not exceed the corresponding preset change rate threshold, it indicates that there is no potential risk in the target hydropower station; by analyzing the unit change rate of water quality information, the change situation of the water body in the water area within a certain time area is obtained, and then it is predicted whether there is a potential risk in the water body in the water area within a certain time period in the future. Discovering potential risks in advance helps to deal with the risks in advance, thereby reducing the probability of potential risks turning into actual risks, and thus helping to reduce the safety risks of hydropower stations.
