Description

An anti-icing and de-icing system for large-scale wind power combined blades

technical field

The invention relates to an anti-icing system for large-scale wind power generation blades in a low-temperature and high-humidity freezing environment, in particular to an anti-icing system for large-scale wind power generation composite blades. the

Background technique

The shortage of traditional energy in the world has caused people's general concern about the depletion of non-renewable energy. The development and utilization of wind energy as a renewable energy has become a hot spot and an inevitable development direction in the world. As an effective way to improve wind energy utilization and power generation efficiency, the single-unit capacity of wind turbines continues to increase. In addition, in our country, the application of wind turbines is not only used in areas with more suitable climates, but also in areas with low temperature, high humidity and freezing.

In the low-temperature and high-humidity icing environment, the aerodynamic characteristics of wind turbine blades are affected by surface ice, and the presence of ice-coated ice on wind power blades will increase the mass of the blades and increase the load on the blades, thereby Changing the lift of the airfoil will significantly reduce the aerodynamic performance of the blades, which will affect the efficiency of wind power generation to a large extent. Icing will further develop under continuous low temperature and high humidity conditions, and even lead to shutdown accidents of wind turbines, resulting in huge economic losses. loss and waste of resources. It is of great significance to research and develop economical, applicable and effective methods for anti-icing and deicing the blades of large wind turbines.

Existing blade deicing technologies mainly include motion shaking deicing, hot air circulation deicing, hot air circulation plus motion shaking, microwave heating, and spraying deicing agents.

Danish Vestas Wind Power System Co., Ltd. applied for a patent with publication number 101821500A "Method for Deicing Wind Turbine Blades, Wind Turbine and Its Application", which belongs to the method of motion shaking deicing. The method described in this patent is, after the wind power generator is shut down, the blades are formed by the pitch-changing motor of the blades to shake off the icing on the blades by first accelerating the pitch-changing and then decelerating. The obvious disadvantage of this method is that due to the high stiffness of the blade root and the small vibration amplitude, the deicing effect on the root is not obvious, and the vibration deicing will cause a large impact on the mechanical system of the entire wind turbine and the structure of the wind power generation tower. , will reduce the service life of related parts and have a greater negative impact on the safety and reliability of the entire wind power generation system.

The publication number that U.S. General Electric Company applies is that the patent of 1727673 belongs to the method for hot air circulation deicing. The patent discloses "Method and Apparatus for Deicing Airfoil or Rotor Blades" by means of a blower that conveys hot air into circulation channels within the blade, the circulation of the hot air between the root and the tip of the blade The flow in the channel heats the blade skin through heat exchange. This method needs to add a hot air circulation channel in the blade cavity, which increases the difficulty and manufacturing cost of the blade manufacturing process. The existence of the circulation channel also inevitably increases the overall quality of the blade, thereby affecting the power generation efficiency. In addition, this method also needs to add an air heating system in the nacelle of the existing wind power generator, which increases cost and energy consumption. Other disadvantages of this method include that for high-power wind turbines with long blades, when the amount of ice is relatively large, since the blade skin material is generally a glass fiber reinforced plastic material formed by glass fiber through resin, it is a poor conductor of heat. To achieve the purpose of melting the ice on the surface of the blade skin, the entire blade skin must first be heated through the inner cavity of the blade. In the case of insufficient heat supply, the heat absorbed by the blade is difficult to meet the requirements of melting ice. To de-ice the blades, the overall temperature of the blade skin must be above zero, which consumes a lot of energy. If the temperature of the heating air inside the cavity is increased, the energy consumption will further increase, and it may even cause the blade to burn. Safety Low. Furthermore, due to the narrow space of the blade tip and the difficulty in reaching the hot air, it is difficult to effectively remove the icing on the blade tip which is most likely to freeze.

The authorized invention patent (authorized notification number CN102003353B) discloses a method for deicing large-scale wind turbine blades, which belongs to the method of hot air circulation and motion trembling, and is a combination of the above two types of methods. This patent first uses the air heating system to input hot air into the circulation channel in the blade, so that the hot air and the skin of the blade perform heat exchange, and the skin after heating provides heat for its surface ice, so that the ice layer absorbs heat and melts. Then use the pitch system and yaw system to accelerate and then decelerate the blades, and the blades vibrate and shake off the ice. The present invention adopts the method of first heating and then fluttering, and it is necessary to add an air heating system in the generator cabin of the existing wind power generator, and to add a hot air circulation channel in the blade, the process is complicated, the cost is increased, and the hot air circulation is added Channels also increase blade weight, affecting power generation efficiency. A more important drawback is that this method uses the pitch system and yaw system to form a motion that first accelerates and then decelerates, and the blades vibrate and shake off the ice. This movement of first acceleration and then deceleration will form a strong impact on the mechanical parts of the generator and the tower structure, posing a threat to mechanical damage.

The method disclosed in the invention patent "a large-scale fan blade deicing system and its method" with the application number 201110394097.5 also uses an exhaust fan and a heater, and the exhaust fan is used to extract the cold air, and the hot air circulates inside the blade to heat the blade skin , to achieve the effect of going out of the ice layer on the surface of the blade skin. The disadvantages of this method are similar to those of the above authorized invention patent (authorized announcement number CN102003353B).

All hot air circulation heating methods also have a common shortcoming. The circulation pipes are difficult to cover the entire blade, and the material of the blade is a poor conductor of heat, so some parts are difficult to achieve the deicing effect.

The invention patent with the application number 20100199260.8 "a wind turbine and its blade deicing system" adopts microwave heating and local excitation. The ice layer is heated by a microwave heating system arranged outside the blade, and then the blade is partially excited to remove the ice layer by using an excitation device. This method needs to arrange a movable microwave transmitting device outside the blade, which has large environmental radiation and great harm to human body. Moreover, a movable vibration excitation device needs to be provided, which is difficult to implement and high in cost. Since the external dimensions of different types of blades are different, the universality of the mobile microwave emitting device is poor.

Sany Electric Co., Ltd. authorized the use of a new type of patent (authorized announcement number CN 202326036U) "a blade deicing device and wind power generator" to spray the ice melting agent to the blade through the ice melting agent pump, delivery pipe and nozzle. deicing. This method also needs to set up an ice-melting agent delivery and injection system outside the tower of the wind power generator, which is costly, and the deicing agent will also cause certain environmental impacts. the

Fig. 9 is a flow chart of temperature control according to an embodiment of the present invention. The output signal of the temperature sensor 6 provided on the surface of the skin 8 and the fiber material layer 2 of the skin 8 is directly input to the temperature controller 7 . When the blade surface temperature is lower than the set control temperature range, the fiber heating power supply 5 keeps energizing and heating the fiber heating layer, and when the blade surface temperature reaches the set temperature control upper limit, the energizing and heating is stopped. When the temperature of the blade drops below the set temperature control range due to heat dissipation, it starts to be energized and heated again.

Figure 10 shows a dimensional plan view of an embodiment of a blade in which a continuous cloth of carbon fiber material is arranged. Figure 11 shows a schematic cross-sectional view of a blade model containing carbon fiber heating materials. The upper and lower layers of the skin are made of glass fiber three-way cloth, with a single layer thickness of 0.54 mm. The middle layer is made of rigid PVC grid with epoxy resin skeleton. The carbon fiber heating material cloth is laid along the length of the model blade along the grain, and copper sheets are used as electrodes at both ends.

The technical principle of the anti-icing and de-icing method for large-scale wind blades in the present invention: Lay fiber heating materials and temperature sensors in the blades. The controller sends out a control command to energize the fiber heating material, and the fiber heating material directly heats the blade, so that the temperature of the blade is kept in the temperature range without freezing or within the set temperature control range. The temperature control range is preferably 3 degrees to 10 degrees above zero. . When the blade has stopped due to icing, the fiber heating material layer is energized and heated to melt the ice first, and then the temperature of the blade is controlled within the non-freezing range to ensure the normal operation of the blade in a low-temperature and high-humidity icing environment. The wind turbine generates electricity normally.

The manufacturing process and deicing process of the system of the present invention are as follows:

1. Before the resin is poured into the skin of the blade, a fiber heating material layer is pre-laid inside the fiber base material near the outer surface, or a fiber heating material layer is directly laid on the outermost or inner surface of the blade, and the outer surface of the skin is pre-laid. Buried temperature sensor, fiber heating material layer and blade fiber base material layer are vacuum infused and cured together;

2. Connect both ends of the fiber heating material layer to the fiber heating power supply and power on, the fiber heating material layer will generate heat and directly heat the blade skin;

3. Use the temperature sensor to measure the surface temperature of the blade, and input the measurement signal into the temperature controller. The temperature controller sends a control signal according to the temperature measured by the blade to control the output power of the fiber heating power supply, and then controls the heating power of the fiber heating material layer;

4. The blades are heated by the heat generated by energizing the fiber heating material layer to keep the temperature of the blades in the range of non-freezing, prevent the blades from freezing, and keep the temperature of the blades within a certain temperature range. In the case that the blade has been frozen, the fiber heating material layer in the blade is energized and heated to melt the ice, and then the above method is used for anti-icing. the
