Description

Technical Field

[0001] The present invention relates to the technical field of offshore devices, and in particular to a wind-solar-wave coordinated dispatching power generation device and method. Background Art

[0002] With the continuous development of the global economy and the continuous growth of population, energy demand has shown an unprecedented growth trend. At the same time, the awakening of environmental protection awareness has made people's demand for clean energy increasingly urgent. In this context, the development and utilization of renewable energy has become a common goal pursued by countries around the world. Wind energy, solar energy and wave energy, as three highly potential renewable energy sources, have shown broad application prospects in the energy field due to their large reserves, wide distribution and clean and pollution-free characteristics.

[0003] However, despite the many advantages of these renewable energy sources, their development and utilization also face many challenges. Single renewable energy generation methods are often strictly restricted by natural environmental conditions. For example, although wind power generation is mature and widely used, its power generation efficiency is easily affected by meteorological factors such as wind speed and wind direction. Similarly, although solar power generation is inexhaustible, its power generation capacity is severely restricted by weather conditions such as sunshine time, cloud cover, and season. As for wave power generation, although it has great development potential in areas rich in marine resources, its power generation efficiency and stability are complexly affected by multiple factors such as marine environment, wave size, and water depth.

[0004] These limiting factors not only affect the stability and reliability of single energy power generation systems, but also make it difficult for these systems to meet large-scale, continuous and stable energy needs. Therefore, how to overcome these limiting factors and achieve efficient, stable and sustainable use of renewable energy has become an important issue that needs to be solved in the current energy field. Summary of the invention

[0103] like Figure 1 As shown, a wind-solar-wave coordinated dispatching power generation device comprises a housing 1 and a sensor module 2, a floating and sinking module 3, a photovoltaic power generation module 4, a wind power generation module 5, a wave power generation module 6 and an intelligent dispatching module 7 installed in the housing 1;

[0104] The sensor module 2 includes a variety of sensors, and the multiple sensors are used to collect environmental data in real time;

[0105] A water storage tank is provided inside the shell 1, and an anchor chain is connected to the outside of the shell 1. The floating module 3 is used to automatically fill or drain water into the water storage tank according to the opening and closing state of the protection mode, and adjust the tension of the anchor chain, thereby adjusting the floating state of the shell 1;

[0106] The photovoltaic power generation module 4 includes a plurality of solar panels whose opening and closing states, azimuth angles and elevation angles are controlled by a control motor, and the plurality of solar panels are used to generate photovoltaic power to obtain solar energy;

[0107] The wind power generation module 5 includes a vertical spiral wind turbine generator, which is used to generate wind power to obtain wind energy;

[0108] The wave energy power generation module 6 comprises a steel disc and two annular permanent magnets connected by a spring telescopic rod and a central rigid shaft. The relative movement of the steel disc between the two annular permanent magnets is used to float up and down with the rise and fall of waves, convert the kinetic energy of the waves into mechanical energy, and generate current through the principle of electromagnetic induction to obtain wave energy;

[0109] The energy storage module 8 is used to store the solar energy, wind energy and wave energy;

[0110] The intelligent scheduling module 7 is used to control whether the floating and sinking module 3 starts the protection mode according to the real-time monitored environmental data, and to switch or coordinate the photovoltaic power generation module 4, wind power generation module 5 and wave energy power generation module 6 according to the protection mode of the floating and sinking module 3.

[0111] The present invention is a wind-solar-wave coordinated dispatching power generation device, the core of which is to maximize the utilization of environmental resources by integrating multiple renewable energy power generation modules and an intelligent dispatching module 7.

These data are transmitted to the intelligent dispatching module 7 for subsequent analysis and decision-making.

[0112] Inside the housing 1, there is a water storage tank, and outside is connected to an anchor chain. The floating module 3 controls the floating state of the housing 1 by automatically filling or draining water into the water storage tank and adjusting the tension of the anchor chain according to the instructions of the intelligent scheduling module 7. This function is particularly important in extreme weather conditions, which can protect the device from damage by natural forces such as wind and waves.

[0113] The photovoltaic power generation module 4 uses a plurality of solar panels to generate photovoltaic power. The opening and closing states, azimuth angles and elevation angles of these solar panels are controlled by a control motor to ensure that they receive solar radiation at the best angle, thereby improving power generation efficiency.

[0114] The wind power generation module 5 adopts a vertical spiral wind turbine generator, which is designed to generate electricity effectively even at lower wind speeds. This generator generates electricity through rotation, converting wind energy into electrical energy.

[0115] The wave energy power generation module 6 uses the relative movement of the steel disc between two annular permanent magnets to capture the kinetic energy of the waves. As the waves rise and fall, the steel disc floats up and down, transferring energy through the spring telescopic rod and the central rigid shaft. In this process, the steel disc cuts the magnetic flux lines to generate current, thereby converting wave energy into electrical energy.

[0116] The energy storage module 8 is responsible for storing the electric energy generated by the photovoltaic power generation module 4, the wind power generation module 5 and the wave power generation module 6.

[0121] 4. Reduce the cost per kilowatt-hour: By optimizing energy configuration and scheduling strategies, the device can reduce the cost per kilowatt-hour and improve economic benefits.

[0122] To further illustrate, the sensor module 2 specifically includes:

[0123] Wave height meter, used to monitor wave information including wave height and wave frequency;

[0129] An acceleration sensor, used to measure the acceleration change of the housing 1 to obtain a vertical displacement;

[0130] The depth sensor is used to monitor the depth of the housing 1 in real time.

[0131] Specifically, the sensor module 2 serves as the "eyes" of the entire system, responsible for collecting marine environmental data in real time and comprehensively, and providing a decision-making basis for the intelligent scheduling module 7.

[0132] The sensor module 2 specifically includes:

[0133] Wave height meter: monitors the height and frequency of waves through high-precision sensors, providing key parameters for the wave energy generation module 6, and also helping the intelligent scheduling module 7 to predict and respond to changes in wave energy.

[0134] Light sensor: installed above the sea level or on the top of the housing 1, used to monitor light intensity and guide the opening and closing state, azimuth and elevation adjustment of the photovoltaic power generation module 4 to maximize the capture efficiency of solar energy.

[0142] A method for dispatching power generation by wind, solar and wave coordination is applied to a dispatching power generation device by wind, solar and wave coordination as described above, comprising the following steps:

[0143] Step A, collecting environmental data in real time through the sensor module 2;

[0144] Step B, judging the current sea condition level according to the environmental data collected in real time, the intelligent scheduling module 7 intelligently switches or coordinates the photovoltaic power generation module 4, the wind power generation module 5 and the wave power generation module 6 to work, and stores the generated solar energy, wind energy and wave energy in the energy storage module 8;

[0145] Step C: When the real-time monitored sea condition data reaches the preset extreme sea condition, the intelligent scheduling module 7 controls the floating and sinking module 3 to start the protection mode, turns off the photovoltaic power generation module 4 and the wind power generation module 5, adjusts the shell 1 to sink to a safe depth, and switches to the wave power generation module 6 to perform independent power generation;

[0146] Step D: During the gradual release of extreme sea conditions, the environmental data is continuously monitored by the sensor module 2. When the real-time monitored environmental data meets the threshold conditions for releasing the extreme sea conditions, the buoyancy module 3 releases the protection mode, adjusts the shell 1 to float to the sea level, and the intelligent scheduling module 7 resumes normal scheduling and power generation functions.

[0147] The present invention provides a wind-solar-wave coordinated dispatching power generation method, which is specially designed and applied to a wind-solar-wave coordinated power generation device that integrates multiple renewable energy power generation modules and an intelligent dispatching module 7. The core of the method is to intelligently switch or coordinate the working states of different power generation modules according to real-time collected marine environmental data to maximize energy utilization efficiency and ensure safe operation of the device.

[0148] The specific steps are as follows:

[0149] Step A: The sensor module 2 in the device collects comprehensive environmental data in real time, including wave height, wave frequency, light intensity, wind speed, wind direction, temperature, humidity, precipitation, shell 1 posture, depth and acceleration, etc. These data provide key basis for subsequent intelligent scheduling.

[0150] Step B: The intelligent scheduling module 7 determines the current sea condition level based on the environmental data collected in real time. According to the sea condition level, the intelligent scheduling module 7 will intelligently switch or coordinate the working states of the photovoltaic power generation module 4, the wind power generation module 5 and the wave power generation module 6. For example, when the sunlight is sufficient and the wind speed is moderate, the photovoltaic power generation module 4 and the wind power generation module 5 may be started first; and in the case of abundant wave energy, the input of the wave power generation module 6 will be increased. The generated solar energy, wind energy and wave energy are stored in the energy storage module 8 for subsequent use.

[0151] Step C: When the real-time monitored sea condition data reaches the preset extreme sea condition, such as storms, huge waves, etc., the intelligent scheduling module 7 will immediately control the floating and sinking module 3 to start the protection mode. In this mode, the photovoltaic power generation module 4 and the wind power generation module 5 will be turned off to avoid damage caused by extreme weather. At the same time, the floating and sinking module 3 will adjust the shell 1 to sink to a safe depth to reduce the impact of waves on the device. During this period, the wave energy power generation module 6 may be switched to a separate power generation mode to use wave energy to replenish energy for the energy storage module 8.

[0152] Step D: As the extreme sea conditions gradually ease, the sensor module 2 will continue to monitor environmental data. When the real-time monitored environmental data meets the preset threshold conditions for easing extreme sea conditions, such as reduced wave height, reduced wind speed, etc., the floating module 3 will release the protection mode and adjust the shell 1 to float to the sea level. At this time, the intelligent scheduling module 7 will resume the normal scheduling power generation function and readjust the working status of each power generation module according to the new environmental data.

[0153] In summary, the beneficial effects of the method of the present invention include:

[0154] 1. Intelligent scheduling and efficient use of energy: Through real-time collection of environmental data and intelligent scheduling strategies, it is possible to intelligently switch or coordinate the working status of each power generation module according to different sea conditions to maximize the use of energy.

[0155] 2. Safety protection and improved device life: Under extreme sea conditions, by starting the protection mode and adjusting the shell depth, the power generation device can be effectively protected from damage and the service life of the device can be extended.

[0156] 3. High degree of automation, reducing operation and maintenance costs: The entire dispatching and power generation process is highly automated, reducing manual intervention and operation and maintenance costs, and improving the economy and sustainability of the system.

[0157] 4. Strong environmental adaptability and wide application range: It is suitable for a variety of marine environmental conditions, can flexibly adjust the working state according to actual conditions, and has strong environmental adaptability.

[0158] Further explanation, in step B, the current sea condition level is determined according to the real-time collected environmental data, and the intelligent scheduling module 7 intelligently switches or coordinates the photovoltaic power generation module 4, the wind power generation module 5 and the wave power generation module 6 to work, as shown in the following table:

[0159]

[0160] Among them, wave height is monitored by a wave height meter; wind speed is monitored by a wind speed and wind direction sensor; and light intensity is monitored by a light sensor.

[0161] Based on the real-time monitored sea condition data, the intelligent scheduling module 7 will determine the current sea condition level and select the appropriate power generation mode to ensure power generation efficiency and equipment safety.

[0162] ① Stable sea conditions (sea state levels 1 and 2, suitable for solar and wind power generation)

[0163] Photovoltaic power generation: When the light intensity reaches the set threshold, the light sensor sends a signal to control multiple solar panels to turn on and capture solar energy.

[0164] Wind power generation: If the wind speed is moderate (within a safe range), the wind speed and direction sensors send a signal and the vertical spiral wind turbine starts generating electricity.

[0165] At this time, photovoltaic power generation and wind power generation can operate simultaneously to increase power output.

[0166] ② Moderate sea conditions (sea condition level 3, suitable for wind and wave power generation)

[0167] Wind power generation: Based on the wind speed data, if the wind speed is suitable and stable, start the vertical spiral wind turbine.

[0168] Wave power generation starts: The wave power generation system starts working according to the height and frequency of the waves. The up and down movement of the waves converts the kinetic energy of the waves into electrical energy through the wave power generation module 6, which is suitable for this type of sea conditions.

[0169] ③ Extreme sea conditions (sea condition levels 4 and 5, suitable for wave energy generation and equipment protection)

[0170] Photovoltaic power generation and wind power generation stop: When the sea conditions reach extreme levels (such as strong winds, heavy rains, typhoons, etc.), the solar panels will be automatically retracted and the vertical spiral wind turbine will be stopped to avoid damage. At this time, the wave power generation module 6 is mainly used for power generation.

[0171] In extreme sea conditions, wave power generation becomes the main source of energy. The wind-light-wave synergistic power generation device will enter a semi-submerged state, and the buoyancy module 3 will adjust the buoyancy of the wind-light-wave synergistic power generation device, so that it sinks to a safe depth, reducing the impact of wind and waves on the wind-light-wave synergistic power generation device. The wave power generation module 6 floats up and down with the rise and fall of waves through the relative movement of two annular permanent magnets, converts the kinetic energy of the waves into mechanical energy, and generates current through the principle of electromagnetic induction to obtain wave energy.

[0172] To further illustrate, in step B, the working process of the photovoltaic power generation module 4 specifically includes the following steps:

[0173] Step B1: collecting light intensity data in real time through the light sensor, comparing it with a set threshold, and adjusting the opening and closing states of the plurality of solar panels by controlling the motor according to the comparison result;

[0174] When the light intensity reaches a set threshold, the motor drives the solar panel to open for photovoltaic power generation;

[0175] When the light intensity does not reach the set threshold, the motor drives the solar panel to close to protect the solar panel;

[0176] Step B2: When the solar panel is turned on, the light sensor continuously monitors the surrounding light intensity and uses the sun position algorithm to calculate the optimal azimuth and elevation angle of the solar panel:

[0177] θ=arcsin(sin(δ)·sin(φ)+cos(δ)·cos(φ)·cos(H))

[0178]

[0179] Among them, θ represents the elevation angle of the sun, that is, the angle between the sun and the horizon; A represents the azimuth angle of the sun, that is, the angle of the sun relative to the north direction; φ is the latitude of the observation point; δ is the declination of the sun; H is the hour angle, which represents the angle difference between the current time and the solar noon time;

[0180] Step B3: According to the optimal azimuth and elevation angles, the motor drives the horizontal axis and the vertical axis of the solar panel to adjust the azimuth and elevation angles of the solar panel to align with the incident direction of sunlight, and the power generation of the solar panel is transmitted to the energy storage module 8;

[0181] The power generation of the solar panel is calculated by radiation:

[0182] P(t)=A·η·G(t)

[0183]

[0184] Where P(t) represents the instantaneous power generation, in W; η represents the comprehensive efficiency of the solar panel, including the panel conversion efficiency, inverter efficiency, temperature effect and dust factor, with a value range of 0.15 to 0.22; A represents the area of ​​the solar panel, in m 2 ; G(t) represents solar irradiance, unit is W / m 2 ; E represents continuous power generation.

[0185] When the solar irradiance G(t) is relatively stable within a certain period of time T, it is approximately a constant G avg :

[0186] E=A·η·G avg ·T.

[0187] In one photovoltaic capacity case, the photovoltaic power generation module (4) uses three solar panels to form an openable and closable state. The area A of a single solar panel is 2.496 m2, the conversion efficiency η of a single solar panel is 15%, and the average solar radiation intensity G of a single solar panel is 600 W / m2. With reference to the normal sunshine time on the sea surface of 8.5 hours, the total daily offshore capacity of the photovoltaic power generation module (4) is expected to reach 5.75 kWh.

[0188] To further illustrate, in step B, the working process of the wind power generation module 5 specifically includes the following steps:

[0189] Step B4: The blades of the vertical spiral wind turbine rotate with the wind, and the blades are connected to the rotor of the vertical spiral wind turbine through the main shaft, driving the rotor to rotate while generating mechanical energy, which is converted into electrical energy and transmitted to the energy storage module 8;

[0190] The power generation of the wind power generation module 5 is calculated as follows:

[0191] P(t)=0.5·ρ·A·v(t) 3 ·C p ·η

[0192] In a period of time, the power generation E is expressed as:

[0193]

[0194] When the wind speed ν(t) remains constant for a period of time T avg , which can be simplified to:

[0195] E=0.5·ρ·A·v avg 3 ·C p ·η·T

[0196] Where P(t) represents the instantaneous power generation, in W; ρ represents the air density, in kg / m 3 ; A represents the swept area of ​​the blade, in m 2 ; A = H·D, where H represents the height of the fan and D represents the diameter of the fan; ν(t) represents the instantaneous wind speed in m / s; C p It represents the power coefficient of converting wind energy into mechanical energy, and its value range is between 0.3 and 0.4; η represents the comprehensive efficiency of the wind power generation system, including the generator efficiency and transmission efficiency, and its value range is between 0.8 and 0.9.

[0197] Specifically, the working process of the wind power generation module 5 mainly depends on the efficient operation of the vertical spiral wind turbine. When natural wind acts on the blades of the generator, the blades will rotate with the wind. These blades are closely connected to the rotor of the generator through the main shaft, so the rotation of the blades will drive the rotor to rotate together. During this rotation process, mechanical energy is generated and then converted into electrical energy. The converted electrical energy will be transmitted to the energy storage module 8 for subsequent use or distribution to the power grid.

[0198] To further illustrate, in step B, the working process of the wave energy power generation module 6 specifically includes the following steps:

[0199] Step B5: Under the continuous action of waves, the steel disc drives the central rigid shaft and the coils at both ends thereof to move up and down. The coils cut the magnetic flux lines and induce current under the action of the magnetic field changes of the two annular permanent magnets. The power generation of the wave energy power generation module 6 is transmitted to the energy storage module 8.

[0200] The power generation of the wave energy power generation module 6 is calculated as follows:

[0201] Define wave motion as simple harmonic motion, the relative velocity v(t) changes with time, and obtain the wave height H s and the fluctuation frequency period T, the relative speed of simple harmonic motion is:

[0202] v(t)=A·ω·cos(ωt)

[0203] in, Indicates the wave amplitude, in m; represents the angular frequency in rad / s; T represents the wave period in s; H s Indicates the wave height in m;

[0204] The average speed is calculated using the maximum value of the wave motion:

[0205]

[0206] According to Faraday's law of electromagnetic induction, the instantaneous value of the induced electromotive force is:

[0207]

[0208] The total electromotive force of the coil is:

[0209]

[0210] The instantaneous power is:

[0211]

[0212] Since the instantaneous power varies with time, its average value P needs to be calculated. avg :

[0213]

[0214] P avg =N·B·L·v avg I

[0215] Substitute v avg , and finally obtain:

[0216]

[0217] Among them, B represents the magnetic induction intensity, the unit is T; N represents the number of coil turns; L represents the effective length of the coil, the unit is m; I represents the current, the unit is A.

[0218] Specifically, the wave energy power generation module 6 can efficiently capture and utilize wave energy through a carefully designed mechanical structure and electromagnetic conversion principle. In terms of the structural design of offshore devices, compared with photovoltaic power generation and wind power generation, wave energy power generation has a higher energy density and a more stable energy output.

[0219] To further illustrate, in step C, the intelligent scheduling module 7 controls the floating and sinking module 3 to start the protection mode and adjusts the housing 1 to sink to a safe depth, which specifically includes the following steps:

[0220] Step C1: monitoring the depth of the housing 1 in real time by means of the depth sensor;

[0221] Step C2: The intelligent scheduling module 7 automatically adjusts the water volume V of the water storage tank according to the depth data. water , so that the buoyancy of the shell 1 is balanced with the gravity to maintain a safe depth;

[0222] The buoyancy of the shell 1 is controlled by the buoyancy formula:

[0223] F b =ρ sea ·V water ·g

[0224] Among them, F b represents buoyancy; ρ sea Indicates the density of seawater; V water It indicates the amount of water in the water storage tank; g indicates the acceleration due to gravity;

[0225] The depth of the housing 1 is adjusted by the gravity formula:

[0226] T hinge =F b ·d

[0227] F b =F g +T hinge

[0228] ρ sea ·V water g = m device ·g

[0229]

[0230] Among them, T hinge represents the tension of the hinge, d represents the lever arm between the center of buoyancy and the hinge point; F g represents the gravity of the housing 1 .

[0231] The core idea of ​​the floating and sinking module 3 is to stabilize the wind-solar-wave synergistic power generation device at a preset depth by adjusting the balance between buoyancy and gravity, and to cope with the interference of external waves and water currents.

[0232] To further explain, in S4, the threshold conditions for relieving the extreme sea condition include a swing amplitude threshold value of less than 0.5 m, a swing time threshold value of more than 18 s, and a swing frequency threshold value of less than 0.15 Hz.

[0233] It should be noted that the swing amplitude threshold refers to the vertical or horizontal displacement amplitude of the wind-solar-wave synergistic power generation device during the wave fluctuations. Setting it to 0.5 meters means that when the maximum displacement of the wind-solar-wave synergistic power generation device (from the water surface to the highest or lowest point of the device) exceeds 0.5 meters, the wave fluctuation amplitude will be considered large and the protection mode needs to be activated.

[0234] The swing time threshold refers to the duration of the periodic fluctuation of the waves. If the vibration or swing of the wind-solar-wave power generation device lasts for more than 18 seconds, it means that the wave period may be long or the fluctuation is large, which may have a lasting impact on the wind-solar-wave power generation device, so the protection mode needs to be activated.

[0235] The oscillation frequency refers to the number of times the vibration or oscillation caused by the waves occurs per second, and the unit is Hertz (Hz). 0.15Hz means that the wave period is longer, which may have a more sustained impact on the wind-solar-wave synergistic power generation device. Therefore, when the frequency value is exceeded, it will be identified as a more extreme sea condition and the protection mode needs to be activated.

[0236] Specifically, firstly, based on the physical characteristics and the characteristics of the actual environment, the threshold conditions of the swing amplitude, time, and frequency are set. Then, in combination with the corresponding sensor signal in the sensor module 2, the frequency and amplitude characteristics are extracted by Kalman filtering or Fourier transform. The multi-source data of the three conditions are comprehensively analyzed using the machine learning algorithm SVM. When the threshold conditions for lifting the extreme sea conditions are met, the protection mode is automatically lifted, and the power generation of solar energy and wind energy is gradually restored to ensure the normal operation of the wind-solar-wave coordinated power generation device.

[0237] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific embodiments of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
