Description

A wind-solar-wave coordinated dispatching power generation device and method Technical Field

[0001] This invention relates to the field of marine equipment technology, and in particular to a wind-solar-wave coordinated dispatching power generation device and method. Background Technology

[0002] With the continuous development of the global economy and the constant growth of the population, energy demand is showing unprecedented growth. At the same time, the awakening of environmental awareness has made the demand for clean energy increasingly urgent. Against this backdrop, the development and utilization of renewable energy has become a common goal pursued by countries around the world. Wind, solar, and wave energy, as three highly promising renewable energy sources, have shown broad application prospects in the energy sector due to their large reserves, wide distribution, and clean, pollution-free characteristics.

[0003] However, despite the numerous advantages of these renewable energy sources, their development and utilization also face many challenges. Single renewable energy power generation methods are often severely limited by natural environmental conditions. For example, while wind power is technologically mature and widely used, its power generation efficiency is highly susceptible to meteorological factors such as wind speed and direction. Similarly, although solar power is inexhaustible, its power generation capacity is significantly constrained by weather conditions such as sunshine duration, cloud cover, and season. Wave power, while possessing enormous development potential in areas rich in marine resources, is subject to complex influences on its power generation efficiency and stability from various factors including the 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 demands. Therefore, overcoming these limiting factors and achieving the efficient, stable, and sustainable utilization of renewable energy has become a crucial issue that urgently needs to be addressed in the energy sector. Summary of the Invention

[0005] One objective of this invention is to propose a wind-solar-wave coordinated dispatching power generation device that combines three renewable energy power generation methods: wind power generation, solar power generation, and wave power generation, in order to solve the problem of the single power generation device in the existing technology.

[0006] Another objective of this invention is to propose a wind-solar-wave coordinated power generation method that achieves complementarity and optimized scheduling among the three renewable energy sources through an advanced control module, and to solve the problems of complementarity and coordination in existing power generation methods.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0009] The sensor module includes multiple sensors, which are used to collect environmental data in real time.

[0010] The shell has a water storage tank inside and an anchor chain connected to the outside. The buoyancy module is used to automatically fill or drain water into the water storage tank according to the opening and closing status of the protection mode, and to adjust the tension of the anchor chain, thereby adjusting the buoyancy of the shell.

[0011] The photovoltaic power generation module includes multiple solar panels whose opening and closing states, azimuth angles, and elevation angles are controlled by a control motor. These multiple solar panels are used to generate solar energy through photovoltaic power generation.

[0012] The wind power generation module includes a vertical spiral wind turbine, which is used to generate wind power and obtain wind energy.

[0013] The wave energy generation module includes 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 the waves, converting the kinetic energy of the waves into mechanical energy, and generating current through the principle of electromagnetic induction to obtain wave energy.

[0014] The energy storage module is used to store the solar energy, wind energy, and wave energy.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0102] As shown in Figure 1, a wind-solar-wave coordinated dispatching and power generation device includes 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 energy power generation module 6, and an intelligent dispatching module 7 installed inside the housing 1.

[0103] The sensor module 2 includes multiple sensors, which are used to collect environmental data in real time.

[0104] The shell 1 has a water storage tank inside, and the shell 1 is connected to an anchor chain on the outside. The buoyancy module 3 is used to automatically fill or drain water into the water storage tank according to the opening and closing status of the protection mode, and to adjust the tension of the anchor chain, thereby adjusting the buoyancy state of the shell 1.

[0105] The photovoltaic power generation module 4 includes multiple solar panels whose opening and closing states, azimuth angles, and elevation angles are controlled by a control motor. These multiple solar panels are used to generate solar energy through photovoltaic power generation.

[0106] The wind power generation module 5 includes a vertical spiral wind turbine generator, which is used to generate wind power and obtain wind energy.

[0107] The wave energy generation module 6 includes 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 undulation of the waves, converting the kinetic energy of the waves into mechanical energy, and generating current through the principle of electromagnetic induction to obtain wave energy.

[0108] The energy storage module 8 is used to store the solar energy, wind energy and wave energy;

[0109] The intelligent scheduling module 7 is used to control whether the buoyancy module 3 starts the protection mode according to the real-time monitored environmental data, and to switch or coordinate the operation of the photovoltaic power generation module 4, wind power generation module 5 and wave power generation module 6 according to the protection mode of the buoyancy module 3.

[0110] This invention discloses a wind-solar-wave coordinated power generation device, the core of which lies in maximizing the utilization of environmental resources by integrating multiple renewable energy power generation modules and an intelligent dispatch module 7. The device first collects environmental data in real time through a sensor module 2, including key information such as wind speed, wind direction, solar radiation intensity, wave height, and wave period. This data is transmitted to the intelligent dispatch module 7 for subsequent analysis and decision-making.

[0111] Inside the shell 1 is a water storage tank, and externally connected to an anchor chain. The buoyancy module 3, according to instructions from the intelligent scheduling module 7, controls the buoyancy of the shell 1 by automatically adding or removing water from the storage tank and adjusting the tension of the anchor chain. This function is particularly important under extreme weather conditions, protecting the device from damage caused by natural forces such as wind and waves.

[0112] Photovoltaic power generation module 4 utilizes multiple solar panels for photovoltaic power generation. These solar panels are controlled by a control motor to regulate their opening and closing states, azimuth angle, and elevation angle, ensuring they receive solar radiation at the optimal angle, thereby improving power generation efficiency.

[0113] Wind power generation module 5 uses a vertical spiral wind turbine, designed to generate electricity effectively even at low wind speeds. This generator produces electrical energy through rotation, converting wind energy into electrical energy.

[0114] The wave energy generation module 6 utilizes the relative motion of a steel disc between two ring-shaped permanent magnets to capture the kinetic energy of waves. As the waves rise and fall, the steel disc floats up and down, transmitting energy through a spring-loaded telescopic rod and a central rigid shaft. During this process, the steel disc cuts magnetic field lines to generate an electric current, thus converting wave energy into electrical energy.

[0115] Energy storage module 8 is responsible for storing the electrical energy generated by photovoltaic power generation module 4, wind power generation module 5, and wave power generation module 6. When the grid demand or energy storage reaches a set threshold, the intelligent scheduling module 7 will automatically switch or coordinate the working status of each power generation module based on real-time monitored environmental data and energy storage status, so as to maximize energy utilization and ensure stable system operation.

[0116] Therefore, the beneficial effects of the device of the present invention include:

[0120] 4. Reduce the cost per kilowatt-hour: By optimizing energy allocation and dispatch strategies, this device can reduce the cost per kilowatt-hour and improve economic efficiency.

[0121] To further explain, the sensor module 2 specifically includes:

[0122] A wave height meter is used to monitor wave information, including wave height and wave frequency.

[0123] Light sensor used to monitor the intensity of light above sea level;

[0126] An attitude sensor is used to collect the tilt angle and depth of the housing 1;

[0127] A posture sensor is used to collect the range of motion, yaw angle and pitch angle of the housing 1 at the diving position;

[0128] An accelerometer is used to measure the acceleration change of the housing 1 to obtain vertical displacement;

[0129] A depth sensor is used to monitor the depth of the housing 1 in real time.

[0130] Specifically, sensor module 2 acts as the "eyes" of the entire system, responsible for collecting marine environmental data in real time and comprehensively, providing decision-making basis for intelligent scheduling module 7.

[0131] Sensor module 2 specifically includes:

[0132] Wave height meter: By monitoring the height and frequency of waves through high-precision sensors, it provides key parameters for the wave energy generation module 6, and also helps the intelligent scheduling module 7 to predict and respond to changes in wave energy.

[0133] Light sensor: Installed above sea level or on top of housing 1, it is used to monitor light intensity and guide the opening and closing status, azimuth angle and elevation angle adjustment of photovoltaic power generation module 4 to maximize solar energy capture efficiency.

[0134] Wind speed and direction sensor: Wind speed and direction data are acquired through rotary or ultrasonic sensors to provide real-time wind condition information for wind power generation module 5, and also to help intelligent scheduling module 7 optimize wind energy utilization strategies.

[0135] Meteorological sensors: These sensors collect meteorological data such as temperature, humidity, and precipitation. This data not only affects the efficiency of photovoltaic and wind power generation, but also serves as an important basis for the intelligent dispatch module 7 to formulate protection modes and adjust power generation strategies.

[0136] Attitude sensor: By collecting tilt angle and depth information of the shell 1 through sensors such as gyroscopes or accelerometers, it helps the intelligent scheduling module 7 monitor the status of the device and ensure its safe operation in complex marine environments.

[0137] Position and attitude sensor: Specifically used to collect the range of motion, yaw angle and pitch angle of the shell 1 in the submerged position, providing accurate position and attitude information for the intelligent scheduling module 7 to optimize power generation efficiency and protect device safety.

[0138] Accelerometer: By measuring the acceleration change of housing 1, vertical displacement information is indirectly obtained, which helps the intelligent scheduling module 7 to activate the protection mode in time under extreme weather conditions and avoid damage to the device.

[0139] Depth sensor: monitors the depth of the housing 1 in real time to ensure that the device operates within the set safe depth range. It can also be used to guide the adjustment of the buoyancy module 3 to adapt to different marine environments.

[0140] Based on the data collected by the sensor module 2, the intelligent scheduling module 7 comprehensively assesses the current environmental conditions and energy demand, and automatically switches or coordinates the working status of the photovoltaic power generation module 4, the wind power generation module 5, and the wave power generation module 6 to maximize energy utilization and ensure stable system operation.

[0141] A wind-solar-wave coordinated power generation method, applied to a wind-solar-wave coordinated power generation device as described above, includes the following steps:

[0142] Step A: Collect environmental data in real time using the sensor module 2;

[0143] Step B: Based on the real-time collected environmental data, determine the current sea state level. The intelligent scheduling module 7 intelligently switches or coordinates the operation of the photovoltaic power generation module 4, wind power generation module 5, and wave power generation module 6, and stores the generated solar energy, wind energy, and wave energy into the energy storage module 8.

[0144] Step C: When the real-time monitored sea state data reaches the preset extreme sea state conditions, the intelligent scheduling module 7 controls the buoyancy module 3 to start the protection mode, shuts down 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 energy power generation module 6 to generate electricity independently.

[0145] Step D: During the gradual relief of extreme sea conditions, the sensor module 2 continuously monitors environmental data. When the real-time monitored environmental data meets the threshold conditions for relieving extreme sea conditions, the buoyancy module 3 deactivates 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.

[0146] This invention discloses a wind-solar-wave coordinated power generation method, specifically designed for use in wind-solar-wave coordinated power generation devices integrating multiple renewable energy power generation modules and an intelligent dispatch module 7. The core of this method lies in intelligently switching or coordinating the operating states of different power generation modules based on real-time collected marine environmental data, thereby maximizing energy utilization efficiency and ensuring the safe operation of the device.

[0147] The specific steps are as follows:

[0148] Step A: The sensor module 2 within 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 attitude, depth, and acceleration. This data provides crucial information for subsequent intelligent scheduling.

[0149] Step B: The intelligent scheduling module 7 determines the current sea state level based on real-time collected environmental data. Depending on the sea state level, the intelligent scheduling module 7 intelligently switches or coordinates the operating states of the photovoltaic power generation module 4, wind power generation module 5, and wave energy generation module 6. For example, under conditions of sufficient sunlight and moderate wind speed, the photovoltaic power generation module 4 and wind power generation module 5 may be activated first; while under sea conditions with abundant wave energy, the operation of the wave energy generation module 6 will be increased. The generated solar, wind, and wave energy is stored in the energy storage module 8 for subsequent use.

[0150] Step C: When the real-time monitored sea state data reaches preset extreme sea state conditions, such as storms or giant waves, the intelligent scheduling module 7 will immediately control the buoyancy module 3 to activate the protection mode. In this mode, the photovoltaic power generation module 4 and the wind power generation module 5 will be shut down to avoid damage caused by extreme weather. At the same time, the buoyancy 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 generation module 6 may be switched to a standalone power generation mode to utilize wave energy to supplement the energy storage module 8.

[0151] Step D: As the extreme sea conditions gradually subside, sensor module 2 will continuously monitor environmental data. When the real-time monitored environmental data meets the preset threshold conditions for resolving extreme sea conditions, such as a decrease in wave height and a reduction in wind speed, buoyancy module 3 will deactivate its protection mode and adjust the hull 1 to float to the sea level. At this time, intelligent scheduling module 7 will resume normal power generation scheduling functions and readjust the operating status of each power generation module according to the new environmental data.

[0152] In summary, the beneficial effects of the method of the present invention include:

[0153] 1. Intelligent scheduling and efficient energy utilization: By collecting environmental data in real time and using intelligent scheduling strategies, the working status of each power generation module can be intelligently switched or coordinated according to different sea conditions to maximize energy utilization.

[0154] 2. Safety protection and extended device lifespan: Under extreme sea conditions, by activating the protection mode and adjusting the shell depth, the power generation device can be effectively protected from damage, extending the device's service life.

[0155] 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.

[0156] 4. Strong environmental adaptability and wide range of applications: It is suitable for various marine environmental conditions and can flexibly adjust its working status according to actual conditions, thus having strong environmental adaptability.

[0157] To further explain, in step B, the intelligent scheduling module 7 intelligently switches or coordinates the operation of the photovoltaic power generation module 4, wind power generation module 5, and wave energy power generation module 6 based on the real-time collected environmental data to determine the current sea state level, as shown in the table below:

[0158]

[0159] Among them, wave height is monitored by a wave height meter; wind speed is monitored by a wind speed and direction sensor; and light intensity is monitored by a light sensor.

[0160] Based on real-time monitored sea state data, the intelligent scheduling module 7 will determine the current sea state level and select an appropriate power generation mode to ensure power generation efficiency and equipment safety.

[0161] ① Stable sea conditions (sea state 1 and 2, suitable for solar and wind power generation)

[0162] 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.

[0163] Wind power generation: If the wind speed is moderate (within a safe range), the wind speed and wind direction sensors will send signals, and the vertical spiral wind turbine will start generating electricity.

[0164] At this time, photovoltaic power generation and wind power generation can operate simultaneously, increasing power output.

[0165] ②Medium sea state conditions (sea state level 3, suitable for wind and wave power generation)

[0166] Wind power generation: Based on wind speed data, if the wind speed is suitable and stable, start the vertical spiral wind turbine.

[0167] Wave power generation startup: The wave power generation system starts working based on the height and frequency of the waves. The up-and-down motion of the waves converts the kinetic energy of the waves into electrical energy through the wave power generation module 6, making it suitable for this type of sea condition.

[0168] ③ Extreme sea state conditions (sea state levels 4 and 5, suitable for wave energy power generation and equipment protection)

[0169] Photovoltaic and wind power generation shutdown: When sea conditions reach extreme levels (such as strong winds, heavy rain, typhoons, etc.), the solar panels will automatically retract and the vertical spiral wind turbine will stop operating to avoid damage. At this time, power generation will mainly rely on wave energy generation module 6.

[0170] In extreme sea conditions, wave energy becomes a primary energy source. The wind-solar-wave co-generation device enters a semi-submersible state, adjusting its buoyancy via the buoyancy module 3 to reach a safe depth and reduce the impact of wind and waves. The wave energy generation module 6 uses the relative motion of two annular permanent magnets to float up and down with the waves, converting the kinetic energy of the waves into mechanical energy, and generating current through electromagnetic induction to obtain wave energy.

[0171] To further explain, in step B, the operation of the photovoltaic power generation module 4 specifically includes the following steps:

[0172] Step B1: The light intensity data is collected in real time by the light sensor and compared with the set threshold. Based on the comparison result, the opening and closing state of the multiple solar panels is adjusted by controlling the motor.

[0173] When the light intensity reaches a set threshold, the motor drives the solar panel to open and generate photovoltaic power.

[0174] When the light intensity does not reach the set threshold, the motor drives the solar panel to close to protect the solar panel;

[0175] Step B2: During the solar panel opening process, the light sensor continuously monitors the surrounding light intensity and uses a solar position algorithm to calculate the optimal azimuth and elevation angles of the solar panel.

[0176]

[0178] in, This indicates the angle of elevation of the sun, that is, the angle between the sun and the horizon; It indicates the azimuth of the sun, that is, the angle of the sun relative to due north; It is the latitude of the observation point; It is the declination of the sun; It is the hour angle, representing the angular difference between the current time and the solar noon time;

[0179] Step B3: Based on the optimal azimuth and elevation angles, the motor drives the horizontal and vertical axes of the solar panel to adjust the azimuth and elevation angles of the solar panel so that it is aligned with the incident direction of sunlight, and the power generated by the solar panel is transmitted to the energy storage module 8.

[0180] The power generation of the solar panel is calculated using radiation.

[0181]

[0182]

[0183] in, Instantaneous power generation, in units of ; This represents the overall efficiency of the solar panel, which includes the panel conversion efficiency, inverter efficiency, and the combined efficiency of temperature and dust factors, with a value ranging from 0.15 to 0.22. The area of ​​the solar panel is expressed in units of 1000 square meters. ; Represents solar irradiance, in units of ; This indicates the continuous power generation.

[0184] When solar irradiance During a certain period of time The internal stability is relatively high, and the constant value is approximately constant. :

[0185] .

[0186] In one of its photovoltaic production capacity cases, the photovoltaic power generation module (4) uses three solar panels to form an openable and closable state, and the area of ​​a single solar panel is... The conversion efficiency of a single solar panel is 2.496㎡. The average solar radiation intensity of a single solar panel is 15%. Given a capacity of 600W / ㎡ and a typical daily sunshine duration of 8.5 hours on the sea surface, the near-shore total production capacity of the photovoltaic power generation module (4) is expected to reach 5.75kWh.

[0187] To further explain, in step B, the operation of the wind power generation module 5 specifically includes the following steps:

[0188] Step B4: The blades of the vertical spiral wind turbine rotate with the wind. The blades are connected to the rotor of the vertical spiral wind turbine through the main shaft, which drives the rotor to rotate and generates mechanical energy, which is then converted into electrical energy and transmitted to the energy storage module 8.

[0189] The power generation of the wind power generation module 5 is calculated as follows:

[0190]

[0191] Over a period of time, power generation Represented as:

[0192]

[0193] When wind speed During a certain period of time Internally remain constant It can be simplified to:

[0194]

[0195] in, Instantaneous power generation, in units of ; This represents air density, with units of 1. ; This indicates the swept area of ​​the blades, in units of... ; ,in Indicates the height of the wind turbine. Indicates the diameter of the fan; Indicates instantaneous wind speed, unit: ; This represents the power coefficient of wind energy converted into mechanical energy, with a value ranging from 0.3 to 0.4. This represents the overall efficiency of a wind power generation system, including generator efficiency and transmission efficiency, with a value ranging from 0.8 to 0.9.

[0196] Specifically, the operation of wind power generation module 5 mainly relies on the efficient operation of the vertical helical wind turbine. When natural wind acts on the turbine blades, the blades rotate with the wind. These blades are closely connected to the turbine rotor via the main shaft, so the rotation of the blades drives the rotor to rotate as well. During this rotation, mechanical energy is generated and subsequently converted into electrical energy. The converted electrical energy is then transmitted to energy storage module 8 for subsequent use or distribution to the power grid.

[0197] To further explain, in step B, the operation of the wave energy generation module 6 specifically includes the following steps:

[0198] Step B5: Under the continuous action of the waves, the steel disc drives the central rigid shaft and the coils at both ends to move up and down. The coils cut magnetic field lines and induce current under the action of the changing magnetic field of the two annular permanent magnets. The power generated by the wave energy generation module 6 is transmitted to the energy storage module 8.

[0199] The power generation of the wave energy generation module 6 is calculated as follows:

[0200] Wave motion is defined as simple harmonic motion, with relative velocity... It changes over time to obtain wave height. and fluctuation frequency period Then the relative velocity of simple harmonic motion is:

[0201]

[0202] in, , representing wave amplitude, in units of ; , represents angular frequency, with units of rad / s; Indicates the wave period, measured in seconds (s). Indicates wave height, in meters (m).

[0203] Average velocity is calculated using the maximum value of the wave motion:

[0204]

[0205] According to Faraday's law of electromagnetic induction, the instantaneous value of the induced electromotive force is:

[0206]

[0207] The total electromotive force of the coil is:

[0208]

[0209] Instantaneous power is:

[0210]

[0211] Since instantaneous power varies with time, its average value needs to be calculated. :

[0212]

[0213]

[0214] Substitution Ultimately, the following was obtained:

[0215]

[0216] in, This represents magnetic flux density, measured in tons (T). Indicates the number of coil turns; This indicates the effective length of the coil, in meters (m). This represents electric current, measured in amperes (A).

[0217] Specifically, the wave energy generation module 6, through its carefully designed mechanical structure and electromagnetic conversion principle, can efficiently capture and utilize wave energy. In terms of the structural design of the offshore device, compared with photovoltaic power generation and wind power generation, wave energy generation has higher energy density and more stable energy output.

[0218] To further explain, in step C, the intelligent scheduling module 7 controls the buoyancy module 3 to activate the protection mode, adjusting the shell 1 to sink to a safe depth, specifically including the following steps:

[0219] Step C1: Monitor the depth of the housing 1 in real time using the depth sensor;

[0220] Step C2: The intelligent scheduling module 7 automatically adjusts the water volume of the water storage tank based on the depth data. This balances the buoyancy and gravity of the shell 1, maintaining a safe depth.

[0221] The hull 1 is buoyant controlled by a buoyancy formula:

[0222]

[0223] in, Indicates buoyancy; Indicates the density of seawater; This indicates the amount of water in the water storage tank; Represents gravitational acceleration;

[0224] The depth of the shell 1 is adjusted using a gravity formula:

[0225]

[0226]

[0227]

[0228]

[0229] in, Indicates the tension of the hinge. This refers to the lever arm between the center of buoyancy and the hinge point; This represents the weight of the shell 1.

[0230] The core idea of ​​the buoyancy module 3 is to stabilize the wind-solar-wave co-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 flow.

[0231] To further explain, in S4, the threshold conditions for relieving extreme sea states include an oscillation amplitude threshold of <0.5m, an oscillation time threshold of >18s, and an oscillation frequency threshold of <0.15Hz.

[0232] It should be noted that the sway amplitude threshold refers to the vertical or horizontal displacement amplitude of the wind-solar-wave cogeneration device during wave fluctuations. Setting it to 0.5 meters means that when the maximum displacement of the wind-solar-wave cogeneration 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 will need to be activated.

[0233] The oscillation time threshold refers to the duration of the periodic fluctuations of the wave. If the vibration or oscillation of the wind-solar-wave cogeneration unit lasts for more than 18 seconds, it indicates that the wave period may be long or the fluctuations may be large, which may have a continuous impact on the wind-solar-wave cogeneration unit, thus requiring the activation of the protection mode.

[0234] Oscillation frequency refers to the number of vibrations or oscillations caused by waves per second, measured in Hertz (Hz). 0.15Hz indicates a relatively long wave period, which may have a more sustained impact on wind-solar-wave co-generation devices. Therefore, exceeding this frequency value is identified as a relatively extreme sea state, requiring the activation of protection mode.

[0235] Specifically, firstly, based on physical characteristics and the features of the actual environment, threshold conditions for swing amplitude, time, and frequency are set. Then, combined with the corresponding sensor signals in sensor module 2, Kalman filtering or Fourier transform is used to extract frequency and amplitude features. The machine learning algorithm SVM is used to comprehensively analyze the multi-source data under the three conditions. When the above threshold conditions for relieving extreme sea conditions are met, the protection mode is automatically deactivated, and solar and wind power generation is gradually restored to ensure the normal operation of the wind-solar-wave co-generation device.

[0236] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
