Description

vertical axis wind turbine

technical field

The utility model relates to the technical field of generator equipment, in particular to a vertical axis wind power generator.

Background technique

Wind energy is a clean, environmentally friendly and renewable resource. Compared with new energy sources such as solar energy, geothermal energy, ocean energy, hydrogen energy, and combustible ice, wind energy power generation is a mature technology, and it does not produce carbon emissions at all. It is the most ideal green energy in the contemporary era.

A wind turbine is a wind powered machine. The wind acts on the blades at a certain speed and angle of attack, causing the blades to generate rotational torque, and through the low-speed shaft, speed-up box, high-speed shaft and other components, the wind energy is converted into mechanical energy, and finally the high-speed generator is driven to generate electricity. It can be used by off-grid users, and can also be fed into the grid through inverters.

A certain type of vertical axis wind power generator in the prior art is a self-developed medium-sized lift-type wind turbine, and its blade rotation centerline is perpendicular to the local geographical horizontal plane. It is suitable for inland areas with rich wind resources (the annual average wind speed is above 5.8m/s, and the equivalent annual utilization hours are not less than 2000 hours). In farms, pastures, mountainous areas and other areas where it is difficult to obtain continuous and stable power supply from the grid, users can choose this product according to their own power needs. At the same time, in calm weather, qualified users can cut into the mains. In the case that the grid can supply power but the voltage is unstable, the unit inverter can stabilize the voltage and filter to protect the user's electrical equipment.

During the period of rapid development of wind turbines in the 1990s and the beginning of this century, the development speed of vertical axis wind turbines was far behind that of horizontal axis wind turbines. Based on the complex hydrodynamic design level at that time (for example, the airfoil is flat, and the traditional blades are heavy, easily corroded, and susceptible to lightning strikes), the wind energy utilization efficiency of the vertical axis fan is not as good as that of the horizontal axis. The traditional vertical axis fan has low fan efficiency, large starting resistance and starting torque, and serious mechanical loss of the system (for example: serious blade air friction, etc.).

Based on the above reasons, vertical axis fans often have low fan efficiency and unstable applications. Therefore, how to overcome the above-mentioned technical defects of the vertical axis fan in the conventional technology is an urgent problem to be solved by those skilled in the art.

The following is a detailed description of the specific design requirements and design principles of the vertical axis wind power generator provided by the embodiment of the present invention:

In the design process of the vertical axis wind turbine, the airfoil design takes into account the efficiency of the fan and the aerodynamic resistance, reduces the starting torque of the motor, and reduces the mechanical loss of the system. According to the GB/T17646-2013 standard, the vertical axis wind turbine belongs to the type of wind turbine. At the same time, in terms of electronic control design, the electronic control system can tolerate 50% (min) of excess power generation by wind turbines.

From the point of view of the entire fan system, there are the following technical characteristics:

1. Easy maintenance:

The blades of the vertical axis wind turbine have a constant inertial force and gravity during rotation, so the fatigue life is higher than that of the horizontal axis; the vertical axis wind turbine has a compact structure, fewer moving parts, and high reliability; generators, The gear box and electric control components are all placed on the ground for easy maintenance.

2. High utilization rate of wind energy:

The wind turbine impeller has high efficiency and good performance. The blade profile adopts the self-developed high-performance profile airfoil FGF1500, which increases the starting bending moment by 10% compared with the traditional airfoil. The curved and twisted blade technology can effectively reduce the range of power variation at various wind speeds. The rated wind speed impeller power coefficient is as high as 0.45, which is 10% to 30% more efficient than similar domestic products.

3. Advanced design:

The design optimization of the vertical axis wind turbine adopts mature aerodynamics and digital grid analysis methods, and has a solid technical foundation. The strength calculation adopts the finite element analysis method to calculate and verify the load under static, dynamic mechanics and stress environment. Under extreme conditions that cannot be verified, simulation calculations show that the survival requirements of the vertical axis wind turbine system are still met. The electronic control system adopts the PWM rectification and inverter scheme, which improves the efficiency and power factor compared with the traditional bridge rectification scheme.

4. High reliability:

Vertical axis wind turbines do not require expensive, failure-prone yaw and pitch systems, reducing costs while increasing reliability. Considering the characteristics of the northern alpine region, the unit adopts low temperature resistance, low air density and anti-wind and sand design to ensure that the unit can adapt to extreme environmental conditions and operate effectively. The tower height of the wind turbine can be configured according to the specific conditions of the wind resources of the wind farm to meet the requirements of various wind farms.

5. Low noise, more beautiful:

The vertical axis wind turbine has a low tip speed ratio, low aerodynamic noise at various speeds, and even achieves a quiet effect at low speeds. It is suitable for installation in residential areas with high noise requirements and densely populated areas.

Basic principles of fan design:

When designing a wind turbine, the parameters adopted will directly affect the utilization rate of the wind turbine, the manufacturing cost of the enterprise and the user's use cost, and also directly affect the development and occupation of the wind turbine market. The basic principles of wind turbine design are as follows:

(1) The design principle of important parts is that the failure of a single part will not lead to the destruction of the whole device;

(2) All important components can withstand all foreseeable loads;

(3) During the equipment inspection and maintenance time interval, the wind power generation device will not experience serious deterioration, taking into account the feasibility of inspection of related parts;

(4) For those parts that cannot be inspected in the fan, it should be ensured that these parts have sufficient durability during the entire service life.

External conditions of wind turbine design: Usually, when designing wind turbines, the influence of external conditions and wind conditions of the built wind farm on wind turbines should be considered.

Wind turbines are subject to environmental (wind and other environmental) and electrical (grid) conditions that can affect the load, durability and operation of the wind turbine. To ensure an appropriate level of safety and reliability, environmental and electrical parameters should be considered in the design.

External conditions can be divided into normal and extreme conditions. Normal external conditions are generally related to long-term structural loads and operating conditions, while extreme external conditions represent rare but possibly critical external design conditions. The design load conditions of wind turbines are determined by these external conditions. conditions combined with wind turbine operating modes.

Wind Turbine Rating Requirements: The external conditions that need to be considered in the design depend on the intended location and type of location where the wind turbine will be installed. Wind turbine classes are defined in terms of wind speed and turbulence. The reference wind speed is the environmental condition that can withstand the average extreme wind speed within 10 minutes at the hub height once in 50 years. The average wind speed is the statistical average of the instantaneous value of the wind speed, and generally refers to the annual average of the wind speed over many years. The designed service life of wind turbines is 20 years.

Other environmental influences: Climatic factors will affect the overall performance and safety of wind turbines. The following environmental conditions should be considered during design: normal and extreme temperature ranges, humidity, air density, solar radiation and rain, hail, snow, icing , lightning and salt spray and other factors.

The influence of load: the following loads should be considered in the design of wind turbines: (1) inertial force and gravity load, which are generated by vibration, rotation, gravity, etc.; (2) aerodynamic load, which is caused by air Various static and dynamic loads resulting from the interaction of flows with fixed and moving parts on wind turbines. (3) Operating load, which is generated by the operation and control of the wind turbine, including mechanical braking and transient loads for the start and stop of the wind turbine. (4) Other loads, such as wake load, impact load, icing load, etc.

It should be noted that the rotor blades of the fan are the most important components for receiving wind energy. The design of the blade requires an airfoil that can better accept wind energy, a reasonable installation angle, a scientific lift-to-drag ratio, a tip speed ratio and a blade profile twist. Because the blades directly face the wind and obtain wind energy, the blades are required to have a reasonable structure, advanced materials and scientific processes, so that the blades can reliably bear various bending moments and tensions acting on the blades, such as wind force, blade weight, centrifugal force, etc. Moreover, the blades are required to be light in weight, high in structural strength and fatigue strength, safe and reliable in operation, easy to install and maintain, simple to manufacture, and low in manufacturing and use costs. In addition, the surface of the blade should be smooth to reduce the frictional resistance with the air when the blade rotates.

The impeller is a unit that absorbs wind energy. It is used to convert the kinetic energy of the air into the mechanical energy of the impeller rotation. The rotation of the impeller is caused by the lift generated by the wind acting on the blades. Reliable lightning protection measures are required.

The overall requirements of fan blades: good aerodynamic shape, which can make full use of the wind energy resources of the wind farm and obtain as much wind energy as possible; reliable structural strength, with sufficient ability to withstand extreme loads and fatigue strength; good aerodynamics Mechanical properties, aerodynamic stability, avoiding resonance and flutter; it has the characteristics of corrosion resistance, lightning protection and convenient maintenance; the optimized structural design reduces the weight of the blade as much as possible and reduces the manufacturing cost.

Main points of blade structure design: blades are the most critical components of wind turbines, and the design of blade shape involves whether the turbine can obtain the designed power. The fatigue strength of the blade is very prominent, because it has to bear large wind load and gravity load. The first thing to consider is the force and moment on the blade and the load situation under specific operating conditions, and the second is to consider the maximum force of the blade, where the load can easily reach the limit of the material.

Blade design parameters: A series of design calculations show that the starting moment of the FGF2-1500 airfoil is about 15% higher than that of the common NACA airfoil, and the rated state power is about 12% higher.

To sum up, the vertical axis wind power generator provided by the embodiment of the utility model overcomes many technical defects of the traditional technology, and has many technical advantages and progress; therefore.
