The present invention relates to an adjustable wall-mounted power generation device and a control method thereof, and more particularly to a power generation device having an adjustment function for causing a wind power generator to generate power at a matched wind speed and a control method thereof.

Wind energy is an available energy generated by the flow of air. The kinetic energy of air flow is called wind energy. The higher the air flow rate, the greater its kinetic energy. Windmills can be used to convert the kinetic energy of wind into useful mechanical energy; wind turbines can convert the kinetic energy of wind into useful power by transmitting the rotational power of the rotor to the generator through the drive shaft. As of 2008, wind power generated by the world is about 94.1 million kilowatts, and the power supplied has exceeded 1% of the world's consumption. Although wind energy is not the main source of energy for most countries, it has grown more than four times between 1999 and 2005.

For example, the patent law of the Republic of China, No. M415984, "The blade expansion device for wind turbines", especially a blade expansion device that adjusts the expansion of the blade to achieve the expansion and contraction effect, mainly by the shaft. The rod, the fixed frame base, the movable frame base, the bracket group and the blade are formed, wherein the shaft rod is fixed on the main seat of the wind power generator; and the fixed frame base is a hollow block and is fixed to the gear block, A bracket group joint block is fixed on the periphery thereof for jointing with the bracket group; and the movable frame base is also a hollow block body, and a plurality of bracket group joint blocks are fixed on the periphery thereof for engaging with the bracket group The bracket set is composed of a plurality of brackets by means of riveting, so that the bracket group can be changed by the expansion and contraction; and the inner side of the blade is fixed with a joint block for engaging with the bracket group; The design is such that when the movable frame is moved upward, one end of the bracket group is also pulled up, so that one end of the bracket group moves downward, and the blade is inwardly contracted; otherwise, if the movable frame is moved downward, one end of the bracket group It also moves down, causing the other end of the stent to rise and the blade to expand outward.

Generally, wind turbines need to be equipped with a brake system to reduce the speed of the brakes when the wind speed is too high, so as to avoid immediate damage to the blades or generator sets by strong winds. Although the wind turbines generally have a brake system, they are often unable to withstand the multiple blows of strong winds due to direct exposure to the open space and no wind-shielding structure. After a period of use, the blades or generator sets will still be damaged. . Although the conventional technique adjusts the expansion of the blade depending on the wind speed, the wind speed of the blade is still unchanged, and the blade is still damaged due to the high rotation speed. Further, although the conventional technique can take up the blade to avoid damage when the wind speed is too large, the power generation cannot be continued when the blade is retracted, and thus the prior art is inconvenient in use.

Please refer to the tenth and eleventh figures. The tenth figure is a schematic diagram of the wind blowing toward the block and away from the block. The eleventh figure shows an example of a wind speed of 8.8 m/s. When the wind speed is reduced near the outer wall, the wind speed is maintained at 8.8 m/s when the outer wall is 300 cm away. When the distance from the outer wall is 100 cm, the wind speed drops to 8 m/s, which is 90% of the original wind speed. When the distance from the outer wall is 44 cm, the wind speed drops to 4.4 m/s, which is 50% of the original wind speed. The curve is extended according to the graph, and it is estimated that the wind speed drops by about 30% of the original wind speed when the distance is 25 cm from the outer wall. The following table shows the relationship between the reduced wind speed and the percentage of the original wind speed when the specified distance from the external wall is shown in Figure 11:

Usually, the maximum wind energy probability occurs at about 10~12 m/s, and the wind speed range also happens to be the wind speed when the general small wind turbine starts to output the maximum power. The wind speed is called the rated wind speed. Speed); When the wind speed is higher than 25~30 m/s, the wind turbine rotor (brake) must be locked and the motor running should be suspended to avoid over-speed operation and damage. The wind speed at this time is called shutdown wind speed (shut-down) Wind speed), but the rated wind speed of the wind turbine is not exactly the same as the wind speed of the shutdown. Depending on the generator specifications and the type and size of the wind turbine, the actual application must be based on the operating characteristics of different wind turbines. By matching the characteristics of the above-mentioned wind speed reduction (Table 1), the distance between the wind power generation unit and the external wall is appropriately controlled to obtain the required windward speed, so that the wind power generation unit can generate electricity at the matched wind speed. And can protect the wind power unit from strong winds.

Referring to FIG. 12, the present invention further provides a control method for an adjustable wall-mounted power generation device according to the present invention, comprising: selecting a shutdown wind speed corresponding to the wind power generation unit; and using an ambient wind speed toward the foregoing block When the body blows, there is a wind speed reduction ratio near the block; when the ambient wind speed is greater than or equal to the shutdown wind speed, the adjustable wall-mounted power generating device is controlled to move the wind power generating unit along the adjusting direction; , causing the wind power unit to match the ambient wind Power generation at a speed. The implementation can be further divided into two modes: a general control mode and a segmentation control mode.

a general control mode: wherein when the ambient wind speed is less than the shutdown wind speed, the adjustable wall-mounted power generating device is controlled, the wind power generating unit is away from the blocking body along the adjusting direction, so that the wind power generating unit generates electricity at the ambient wind speed Controlling the adjustable wall-mounted power generating device when the ambient wind speed is greater than or equal to the shutdown wind speed, the wind power generating unit is close to the blocking body along the adjusting direction, and the distance between the wind power generating unit and the blocking body is the minimum The wind power generation unit is placed at a reduced ambient wind speed. In actual implementation, the wind power generation unit can operate normally at the ambient wind speed, and it can be prevented from being damaged by strong winds as the main control consideration. The method is as follows: when the ambient wind speed is less than the shutdown wind speed, the distance between the pivot center of the wind power generation unit and the outer wall is about 100-150 cm, or the wind power generation unit and the outer wall are the most accessible under the limitation of the unit structure size. At a long distance, it can still draw more than 90% of the wind energy in the original environment and operate normally, and this distance is also the starting position when the wind power unit generally starts to operate. However, when the ambient wind speed is greater than or equal to the shutdown wind speed of the wind turbine, the wind power generation unit is controlled to move and approach the outer wall, so that the distance between the pivot center and the outer wall is within 25 cm, or under the limitation of the unit structure size. The wind power unit and the outer wall can reach the closest distance to reduce the windward speed of the wind power unit, and ensure that the wind power unit does not damage or even operate normally under the strong wind.

a segmentation control mode: wherein the wind power generation unit corresponds to one of the rated wind speeds of the preferred power generation, and the adjustable wall-mounted power generation device is controlled by the wind speed reduction ratio, and the wind power generation unit is away from the adjustment direction Or, by entering the foregoing blocking body, the wind power generation unit generates electricity under the condition that the reduced ambient wind speed matches the rated wind speed. In actual implementation, the wind power generation unit can operate normally under normal ambient wind speed, and can still stably operate at maximum output power without damage due to strong wind speed attack. The method is that when the ambient wind speed is less than the shutdown wind speed, the distance between the pivot center of the wind power generation unit and the outer wall is about 100-150 cm, or Under the structural size limitation, the wind power unit can reach the farthest distance from the external wall, so that it can still capture more than 90% of the wind energy in the original environment and operate normally, and this distance is also the time when the wind power unit generally starts to operate. When the ambient wind speed is greater than or equal to the shutdown wind speed of the wind power generation unit, the wind power generation unit is controlled to gradually move toward the outer wall in stages according to the current wind speed, so that the distance between the pivot center and the outer wall is The change was adjusted according to the size of the ambient wind speed at that time. When the ambient wind speed is equal to the shutdown wind speed, the first stage first controls the wind power generation unit to move and approach the outer wall, so that the distance between the pivot center and the outer wall is about 56 cm, so that the windward speed of the wind power generation unit is first reduced. It is 60% of the original wind speed and continuously monitors the wind speed; when the ambient wind speed is equal to 1.5 times the shutdown wind speed, the second stage control is performed to make the wind power unit continue to move and approach the outer wall, so that the pivot center and the outer wall The distance is about 36 cm, firstly reducing the windward speed of the wind power unit to 40% of the original wind speed, and continuously monitoring the wind speed; when the ambient wind speed is greater than or equal to twice the shutdown wind speed, the third stage control is performed to make the wind The power generation unit continues to move and approach the outer wall, and the distance between the pivot center of the wind wheel and the outer wall is less than 25 cm, or the wind power unit can reach the closest distance to the outer wall under the structural size limit of the unit, so as to The windward speed of the wind power unit is reduced to less than 30% of the original wind speed to ensure that the wind turbine can continue to operate without being damaged by strong winds; and when the ambient wind speed is small When the wind speed of the wind turbine is turned off, the wind power generation unit is controlled to be away from the outer wall and returned to the starting position, and the distance is also the starting position when the wind power generating unit generally starts to operate. If the wind power generation unit with the shutdown wind speed of 25~30 m/s and the rated wind speed of 12-18 m/s is taken as an example, and calculated in the above embodiment, the ambient wind speed is equal to the shutdown wind speed. At time (30 m / s), the wind speed is reduced to 30 × 60% = 18 m / s (rated wind speed) after the external wall is reduced (the first stage control); when the ambient wind speed is equal to 1.5 times the shutdown wind speed ( 45 m / s), after the wind speed is reduced by the external wall (second stage control) is reduced to 45 × 40% = 18 m / s (rated wind speed); when the ambient wind speed is equal to twice the shutdown wind speed (60 m / s), the wind speed is reduced to 60 × 30% = 18 m / s (rated wind speed) after the external wall is reduced (third stage control). It can be confirmed from the above calculation results that the segmentation control mode can make the wind power generation unit stably stable even in a strong wind environment exceeding the shutdown wind speed. The large output power mode works normally and is not damaged. Although the embodiment is divided into three-stage control, in actual application, the number of stages can be changed according to the demand at the time.
