[0039] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, but not all embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0040] The core of the present application is to provide a water reservoir evaporation change measurement system, method, device and medium.

[0041] In order to enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Figure 1 The structural diagram of the water reservoir evaporation change measurement system provided by the embodiment of the present application is shown in Figure 1 The water reservoir evaporation change measurement system includes water inflow measurement device 1 and water outflow measurement device 2. Figure 2 The structural diagram of another water reservoir evaporation change measurement system provided by the embodiment of the present application is shown in Figure 2 The water reservoir evaporation change measurement system includes water inflow measurement device 1, water outflow measurement device 2, hydropower station reservoir 3, floating photovoltaic power station 4, water level measurement device 5, flood discharge valve 6, ambient temperature measurement device 7, irradiance measurement device 8 and wind measurement device 9.

[0043] As shown in Figure 1 The water reservoir evaporation change measurement system of the embodiment of the present application includes water inflow measurement device 1 and water outflow measurement device 2; the water inflow measurement device 1 is arranged at the water inlet of the hydropower station reservoir 3, and is used to measure the first water inflow before the construction of the floating photovoltaic power station 4 in the hydropower station reservoir 3 and the second water inflow after the construction of the floating photovoltaic power station 4; the water outflow measurement device 2 is arranged at the water outlet of the hydropower station reservoir 3, and is used to measure the first water outflow before the construction of the floating photovoltaic power station 4 in the hydropower station reservoir 3 and the second water outflow after the construction of the floating photovoltaic power station 4; the first water inflow, the second water inflow, the first water outflow and the second water outflow are used to calculate the change of the evaporation amount of the hydropower station reservoir 3 before and after the construction of the floating photovoltaic power station 4.

[0044] The change in the evaporation amount in the embodiments of the present application can be the difference between the first water inflow and the first water outflow minus the difference between the second water inflow and the second water outflow. It can be calculated by the staff according to the first water inflow, the second water inflow, the first water outflow and the second water outflow. It can also be that the water inflow measuring device 1 and the water outflow measuring device 2 are both connected to the terminal, and the terminal calculates the change in the evaporation amount according to a pre-set formula after obtaining the first water inflow, the second water inflow, the first water outflow and the second water outflow. The terminal can be a computer or a mobile phone, etc.

[0045] The change in the evaporation amount of the reservoir provided in the embodiments of the present application is measured by a system, which comprises a water inflow measuring device and a water outflow measuring device. The water inflow measuring device is arranged at the water inlet of the reservoir of the hydropower station, and is used to measure the first water inflow before the construction of the floating photovoltaic power station and the second water inflow after the construction of the floating photovoltaic power station. The water outflow measuring device is arranged at the water outlet of the reservoir of the hydropower station, and is used to measure the first water outflow before the construction of the floating photovoltaic power station and the second water outflow after the construction of the floating photovoltaic power station. The first water inflow, the second water inflow, the first water outflow and the second water outflow are used to calculate the change in the evaporation amount of the reservoir of the hydropower station before and after the construction of the floating photovoltaic power station. The change in the evaporation amount of the reservoir of the hydropower station before and after the construction of the floating photovoltaic power station is calculated by measuring the water inflow and the water outflow. The calculated change in the evaporation amount is relatively accurate, and can provide technical support for formulating a coupled power generation strategy that meets the load curve.

[0046] In order to make the calculated change in the evaporation amount more accurate, the influence of the change in the volume of the reservoir, the environmental temperature, the irradiance, the wind force and the like needs to be excluded. The embodiments of the present application further comprise a water level measuring device 5, an environmental temperature measuring device 7, an irradiance measuring device 8 and a wind force measuring device 9. The water level measuring device 5, the environmental temperature measuring device 7, the irradiance measuring device 8 and the wind force measuring device 9 are respectively used to measure the water level, the temperature, the irradiance and the wind force of the reservoir 3 of the hydropower station.

[0047] Before measuring the inflow and outflow, the staff keeps the measured value of the water level measuring device 5 of the reservoir 3 of the hydropower station constant by adjusting the inlet guide vanes of each water turbine of the hydropower station (communicate with the power grid in advance, and the power generation of the hydropower station is freely adjusted during the test period). The flood discharge valve 6 of the hydropower station is closed during the test period. That is, the first inflow and the first outflow are measured before the floating photovoltaic power station 4 is constructed in the reservoir 3 of the hydropower station, and the second inflow and the second outflow are measured after the floating photovoltaic power station 4 is constructed in the reservoir 3 of the hydropower station. The value of the water level measuring device 5 of the reservoir 3 of the hydropower station is kept the same during the two measurements. Of course, the two measurements are carried out on sunny days, and the environmental temperature, irradiance and wind force are as same as possible. Thus, the influence of other factors on the evaporation amount is excluded.

[0048] The specific experimental process is as follows:

[0049] 1) Test once before the construction of the floating photovoltaic power station 4 in the reservoir 3 of the hydropower station, the measured value Q11 of the inflow measuring device 1 of the reservoir 3 of the hydropower station, and the measured value Q12 of the outflow measuring device 2 of the reservoir 3 of the hydropower station.

[0050] 2) Test once after the construction of the floating photovoltaic power station 4 in the reservoir 3 of the hydropower station, the measured value Q21 of the inflow measuring device 1 of the reservoir 3 of the hydropower station, and the measured value Q22 of the outflow measuring device 2 of the reservoir 3 of the hydropower station.

[0051] 3) The value of the water level measuring device 5 of the reservoir 3 of the hydropower station is kept unchanged during the test process, and the influence of the change in the volume of the reservoir is excluded; the two tests are carried out on sunny days, and the environmental temperature, irradiance and wind force are the same, and the influence of precipitation in the reservoir area and the influence of the evaporation coefficient are excluded; the experimental process is the difference between the two measurements, and the influence of other factors is excluded.

[0052] 4) ΔQ = (Q11-Q12)-(Q21-Q22), ΔQ is the change in the evaporation amount of the reservoir before and after the construction of the floating photovoltaic power station 4 in the reservoir 3 of the hydropower station.

[0053] The reservoir evaporation change measurement system provided by the embodiment of the application has reasonable structure design, strong practicability, is suitable for use in the photovoltaic power generation industry, and has operability. The system has scientificity and can meet the requirements of measuring the change in the evaporation amount of the reservoir before and after the construction of the floating photovoltaic power station in the reservoir of the hydropower station. The system measures the evaporation data before and after the construction of the floating photovoltaic power station in the reservoir of the hydropower station, provides technical support for formulating a coupled power generation strategy that meets the load curve, and improves the intelligent operation and maintenance level of the hydropower station.

[0054] Figure 3 The flowchart of the reservoir evaporation change measurement method provided by the embodiment of the application is applied to the reservoir evaporation change measurement system in the above embodiment, like Figure 3The reservoir evaporation amount change measurement method shown includes:

[0055] S10: Before the floating photovoltaic power station is constructed in the reservoir of the hydropower station, a first inflow flow rate measured by the inflow flow rate measuring device and a first outflow flow rate measured by the outflow flow rate measuring device are obtained.

[0056] S11: After the floating photovoltaic power station is constructed in the reservoir of the hydropower station, a second inflow flow rate measured by the inflow flow rate measuring device and a second outflow flow rate measured by the outflow flow rate measuring device are obtained.

[0057] S12: The change amount of the evaporation amount of the reservoir of the hydropower station before and after the floating photovoltaic power station is constructed is calculated according to the first inflow flow rate, the second inflow flow rate, the first outflow flow rate and the second outflow flow rate.

[0058] Specifically, when the first inflow flow rate measured by the inflow flow rate measuring device 1 and the first outflow flow rate measured by the outflow flow rate measuring device 2 are obtained before the floating photovoltaic power station 4 is constructed in the reservoir 3 of the hydropower station 3, the first temperature measured by the environmental temperature measuring device 7, the first irradiance measured by the irradiance measuring device 8 and the first wind force measured by the wind force measuring device 9 are also recorded; correspondingly, when the second inflow flow rate measured by the inflow flow rate measuring device 1 and the second outflow flow rate measured by the outflow flow rate measuring device 2 are obtained after the floating photovoltaic power station 4 is constructed in the reservoir 3 of the hydropower station 3, the second temperature measured by the environmental temperature measuring device 7, the second irradiance measured by the irradiance measuring device 8 and the second wind force measured by the wind force measuring device 9 are recorded after the floating photovoltaic power station 4 is constructed in the reservoir 3 of the hydropower station 3; it is judged whether the difference between the first temperature and the second temperature, the difference between the first irradiance and the second irradiance and the difference between the first wind force and the second wind force satisfy the respective corresponding threshold values; if yes, the second inflow flow rate and the second outflow flow rate are obtained; the difference between the first inflow flow rate and the first outflow flow rate is calculated as a first measurement value, and the difference between the second inflow flow rate and the second outflow flow rate is calculated as a second measurement value; the difference between the first measurement value and the second measurement value is calculated as the change amount of the evaporation amount.

[0059] For the convenience of understanding, an example is given. During the measurement process, the staff adjusts the inlet guide vanes of each water turbine of the hydropower station (the test period is free to adjust the power generation of the hydropower station after communicating with the power grid in advance) to keep the measurement value of the water level measuring device 5 of the reservoir 3 of the hydropower station constant, and the flood discharge valve 6 of the hydropower station is closed during the test period. Test conditions before the construction of the floating photovoltaic power station 4 in the reservoir 3 of the hydropower station: sunny weather, environmental temperature 19.3 degrees Celsius, total irradiance 4938.84 MJ / m 2a, wind force 1.4 m / s; the measured value Q11 of the water inflow measuring device 1 of the hydropower reservoir 3 is 3500 cubic meters per second, and the measured value Q12 of the water outflow measuring device 2 of the hydropower reservoir 3 is 3499.988 cubic meters per second. After the construction of the floating photovoltaic power station 4 of the hydropower reservoir 3, the test conditions are: sunny weather, ambient temperature 20.1 degrees Celsius, total irradiance 4952.52 MJ / m 2 a, wind force 1.5 m / s; the measured value Q21 of the water inflow measuring device 1 of the hydropower reservoir 3 is 3500 cubic meters per second, and the measured value Q22 of the water outflow measuring device 2 of the hydropower reservoir 3 is 3499.998 cubic meters per second. The value of the water level measuring device 5 of the hydropower reservoir 3 remains unchanged during the test process, which eliminates the influence of the change of the reservoir volume; both tests are carried out on sunny days, and the ambient temperature, irradiance and wind force are similar, which eliminates the influence of precipitation in the reservoir area and the influence of evaporation coefficient; according to the above data, the change value ΔQ of the reservoir evaporation before and after the construction of the floating photovoltaic power station 4 of the hydropower reservoir 3 is calculated as follows: ΔQ = (3500-3499.988)-(3500-3499.998) = 0.01 cubic meters per second.

[0060] The water reservoir evaporation change measurement method provided by the embodiment of the present application is applied to a water reservoir evaporation change measurement system. Before the construction of the floating photovoltaic power station of the hydropower reservoir, the first water inflow measured by the water inflow measuring device and the first water outflow measured by the water outflow measuring device are obtained. After the construction of the floating photovoltaic power station of the hydropower reservoir, the second water inflow measured by the water inflow measuring device and the second water outflow measured by the water outflow measuring device are obtained. The change of the evaporation of the hydropower reservoir before and after the construction of the floating photovoltaic power station is calculated according to the first water inflow, the second water inflow, the first water outflow and the second water outflow. The change of the evaporation of the hydropower reservoir before and after the construction of the floating photovoltaic power station is calculated by measuring the water inflow and the water outflow.
