[0002]

2. Description of the Related Art Conventionally, a wind turbine generator has a rotating shaft, a brake, a speed increaser, a generator, etc. in a nacelle or a supporting column, so that heat is easily generated and a fire may occur. Many measures are taken to prevent the occurrence of fire. For example, a speed reducer is provided or the angle of the blade is changed to prevent overload. Also,
Using a flame-retardant material such as Teflon (registered trademark),
It is equipped with a lightning rod to prevent ignition due to vibration heat and to prevent a fire due to a lightning strike.

[0003]

However, in the conventional wind turbine generator, despite the measures as described above, it is caused by abnormal weather or when abnormal weather overlaps with other adverse conditions. With respect to the fires, no one has an effective means for extinguishing the fire once it occurs.

In addition, installing a new fire extinguishing facility
There is a problem in that the cost of the entire wind turbine generator is increased. In particular, the nacelle portion, which may cause a fire, is several tens of meters above the ground, and there is a problem in that it costs a great deal to install a fire extinguishing facility at that height. Wind power generators will continue to grow in size, and the above problems will become more prominent.

Usually, the wind power generator is often installed in an area away from a private house, which not only delays the discovery of a fire but also cannot promptly perform a fire extinguishing operation that requires manpower for the fire extinguishing operation. There was a problem.

In order to solve the above-mentioned problems of the prior art, the present invention is capable of promptly and surely extinguishing a fire when a fire occurs and preventing a secondary disaster due to the fire. The purpose is to provide a driving method.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a method for operating a wind turbine generator according to the present invention will be described in detail below with reference to the accompanying drawings.

(Structure of Wind Power Generator) Wind power generators are roughly classified into two types: a horizontal axis wind turbine whose rotation axis is horizontal to the ground and a vertical axis wind turbine whose rotation axis is vertical to the ground. 1 and 2 are a front view and a side view showing the appearance of a wind turbine generator of a propeller type wind turbine as an example of a horizontal axis wind turbine.
As shown in FIGS. 1 and 2, in a wind turbine generator of a propeller type wind turbine as an example of a horizontal axis wind turbine, 1 is a blade that constitutes the wind turbine, 2 is a nacelle, and 3 is a blade 1 and a nacelle 2. It is a pillar for supporting.

FIG. 3 is an explanatory view showing the internal arrangement of the nacelle 2. In FIG. 3, 10 is a main shaft, 11 is a main bearing for receiving the main shaft 10, 12 is a speed increaser (gearbox) for changing the rotation speed of the main shaft 10, and
3 is a brake that stops the rotation of the second shaft 20 connected to the speed increaser 12, 14 is a generator that generates electrical energy by the rotation of the second shaft 20, and 15 is for opening and closing the nacelle. A nacelle opening / closing unit, 16 is a maintenance crane, 17 is a cooler (radiator) for cooling the entire nacelle 2 or the generator 14, and 18
Is a flame generation detection unit that detects when a flame is generated in the nacelle 2, and 19 is a fire extinguishing unit that extinguishes the flame generated in the nacelle 2.

Although not shown in the figure, a notification unit for notifying the flame occurrence information to a predetermined contact, such as a management center, a fire station or the police, based on the detection by the flame occurrence detection unit 18, is provided. The notification unit is configured by, for example, a wireless transmission device or the like, and automatically transmits a signal indicating the occurrence of flame. Similarly, although not shown, the flame occurrence detection unit 1
A warning sound (siren) or warning sound (for example, "Since it is dangerous, please evacuate quickly from this area."
The alarm output unit (speaker) that outputs the voice) is installed. The location where the alarm output section is installed is, for example, column 3.
It is recommended to install it at either height.

In such a structure, the rotation of the blade 1 is transmitted to the main shaft 10, and the speed of the rotation is changed (accelerated) by the speed increaser 12. The generator 14 generates power by the accelerated rotation. Further, the brake 13 adopts a disc type brake and stops the rotation of the second shaft 20 as necessary. This also stops the rotation of the main shaft 10,
Therefore, the rotation of the blade 1 is stopped.

The flame generation detector 18 is arranged in the nacelle 2 and is composed of a temperature sensor, a smoke sensor, an ultraviolet sensor and the like. In any case, it can be judged that a flame has occurred when the value exceeds a predetermined value. In addition, the current or voltage value measuring device of the generator 14, the wind speed measuring device, the spindle 10
Alternatively, the second shaft 20 may be configured by a rotation speed measuring device or the like. In this case, although the occurrence of the flame is not directly detected, it is preferable to start the fire extinguishing or the stopping operation after determining that the abnormal situation in which the flame is likely to occur has occurred.
Further, when the flame occurrence detection unit 18 is each of the above-mentioned measuring instruments, it is not necessarily required to be arranged in the nacelle 2. Furthermore, the flame occurrence detection unit 18 may be a combination of the above-mentioned sensors or a combination of any of the above-mentioned sensors and the above-mentioned respective measuring instruments. This makes it possible to detect the occurrence of flame more accurately.

Similarly, the fire extinguishing unit 19 is also arranged in the nacelle 2 and executes the fire extinguishing process based on the detection by the flame occurrence detecting unit 18. Therefore, it is not necessary for the administrator to remotely operate the fire extinguishing unit 19 in order to operate the fire extinguishing unit 19, so that the fire can be extinguished quickly. A detailed description of the extinguishing method will be described later.

In FIG. 3, the fire extinguishing section 19 is provided in only one place in the nacelle 2, but it is not limited to this and may be provided in a plurality of places. At this time, it is preferable to separately provide the components (the speed increasing gear 12, the brake 13, the generator 14) so as to correspond to the respective components. Furthermore, it is more effective to make the extinguishing method of the fire extinguishing section 19 different according to the characteristics of each component (for example, the gearbox that is the speed increaser 12 uses a lot of oil).

FIG. 4 is an external view showing the appearance of a Darrieus-type wind turbine wind power generator as an example of a vertical axis wind turbine. As shown in FIG. 4, in a Darrieus-type wind turbine wind power generator as an example of a vertical axis wind turbine, 31 is a blade that constitutes the wind turbine, and 32 is a support for supporting the blade 31.

FIG. 5 is an explanatory view showing the internal arrangement of the support column 32. In FIG. 5, 33 is a main shaft, 34 is a main bearing that receives the main shaft 33, and 3
5 is a generator that generates electric energy by the rotation of the main shaft 33, 36 is a brake that stops the rotation of the main shaft 33, 37 is a flame generation detection unit, and 38 is a fire extinguishing unit.

Further, similar to the wind turbine generator of the propeller type wind turbine shown in FIGS. 1 to 3, a predetermined contact point, such as a management center or a fire station, is detected based on the detection by the flame generation detecting section 37.
A notification unit for notifying the police of the flame occurrence information, and an alarm output unit (speaker) for outputting an alarm sound (siren) or an alarm sound indicating the flame occurrence to the area around the own device based on the detection by the flame occurrence detection unit 37. Is equipped with. The above-mentioned components are the same as those of the wind turbine generator of the propeller type wind turbine shown in FIGS.

(Details of Fire Extinguishing Method) Next, a fire extinguishing method by the fire extinguishing units 19 and 38 will be described. Generally, there are the following three methods for extinguishing a flame, and it is possible to extinguish a flame if one of the following is achieved. First, the flame and the burning combustible material are separated from each other. Second, the combustibles around the fire point liquefy when receiving energy from the flame.
Prevents vaporization and phase change to flammable gas (cooling effect). Third, it blocks oxygen around the fire point (suffocation effect).

Generally, in the case of a fire, the combustible material around the flame receives energy from the flame and is liquefied / vaporized to become a combustible gas, which ignites / burns and the flame continues. The combustibles at this time are liquefied
The energy required to vaporize and become flammable gas is called activation energy. At the time of fire, it is attempted to extinguish the fire by spraying water on the flame by evaporating water around the fire point, depriving the heat energy of the flame by latent heat of vaporization of water, reducing the energy below the activation energy, and burning combustible materials around the flame. This is aimed at the effect of preventing the gasification of (cooling effect).

In consideration of this effect, normally, the explosives are safely held, and when a fire occurs, the explosives are exploded in a fire extinguisher near the fire point, so that a fire is caused by expansion of gas after the explosion reaction. Effective in a wide range by moving the flame away from combustibles around the point and causing local suffocation around the fire point and at the same time making the extinguishing agent around the explosive material atomize to reach the fire point by the explosion reaction. The fire extinguishing agent is sprayed in a very short time to extinguish the heat energy of the flame to extinguish the fire, and the suffocating effect of water vapor is expected. .

Further, the fire extinguishing agent can be atomized and reach in a wide range near the fire point, and the fire can be extinguished with a very small amount, and the amount of explosives is small compared to the method of extinguishing only with the blast. The fire extinguishing method is applicable to various kinds of fires, and there is little risk that the nacelle 2 or the column 32 is damaged by explosion.

FIG. 6 is an explanatory view showing the structure of an explosion extinguisher as the fire extinguishing section 19 or 38. In FIG. 6, 40
Is a ball-shaped soft plastic container, and a nonflammable liquid 41 such as a digestive agent is filled in the container 40. A ball-shaped hard plastic container 42 is arranged in the layer of the nonflammable liquid 41, and the explosives 4 are placed inside the container 42.
3, the explosive material 43 is filled with the ignition powder 44 in the central portion thereof.

The ignition pipe 44 is made of a plastic pipe 4
One end of a high-speed squib 46 that penetrates 5 is connected, and the other end of the high-speed squib 46 is connected to an ignition charge 47 mounted on the outer surface of the container 40. This plastic pipe 4
Reference numeral 5 is for shutting off the high-speed squib 46 from the incombustible liquid 41. In order to guide the fire ignited by the ignition powder 47 to the explosive material 43 by the high-speed squib 46, the pipe 4 made of plastic is used.
The inner diameter of 5 must be 1 mm or more.

In the fire extinguishing section 19, 38 (explosion extinguisher) having the above structure, the ignition powder 47 is ignited, so that the fire propagates through the high-speed squib 46 and is placed in the central portion of the explosive material 43. By igniting 44, explosives 4
3 explodes. The generation / diffusion of the inert gas generated by this explosion and the blast explode the container 42 made of hard plastic into fine pieces and diffused to destroy the container 40 made of soft plastic. Container 4 due to the diffusion and blast of this gas
The non-flammable liquid 41 filled inside 0 is instantly atomized and diffused.

Therefore, by detonating the explosion extinguisher having the above structure in the vicinity of the fire point when a fire occurs, the flame is extinguished by the diffusion of the inert gas and the blast generated at that time, and at the same time, the above-mentioned finely divided incombustibility is produced. The liquid will cover the combustibles that remain after the blown flame. As a result, not only is the flame blown out by the explosion of the explosive material 43, but even if fresh air containing sufficient oxygen is blown into the vicinity of the original fire point again, it will be burned by the atomized non-combustible liquid, so there is a risk of re-combustion. Disappears.

The explosive material 43 is, for example, an explosive material such as "nitrocellulose" or "sodium azide + CuO", and the igniting agent 44 and the igniting agent 47 are, for example, "boron + lead peroxide" and " Tricinate "
And so on. To ignite and explode the explosive, an amount of 1 to 10% of the weight of the ignition charge 44 is required. Further, when the explosive material 43 explodes, the container of the hard plastic container 42 is destroyed. However, if a crack is first formed by the explosion, the gas generated by the explosion easily advances in that direction, so Since the action of forming fine particles is less likely to occur, in order to prevent this, the container 42 is provided with a number of uniform grooves so that the container 42 can be broken into uniform fine pieces.

As described above, by providing the ignition powder 47 on the outer surface of the container 40, the fire extinguishing unit 19,
When 38 (explosion extinguisher) is in the flame, the ignition powder 47 is ignited by the flame and propagates through the high-speed fuse 46, and the explosive material 43 is ignited and explodes. The explosives 43 will automatically explode simply by installing them, blow off the flame, and atomize the non-combustible liquid 41,
The combustible material remaining after the flame is blown out with the atomized non-combustible liquid 41 is covered. So in this case,
Since the igniting agent 47 acts as the flame generation detection units 18 and 37, it is not necessary to newly provide the flame generation detection unit. Of course, the ignition powder 4 is generated by the detection signal from the flame occurrence detection unit.
7 may be ignited.

The extinguishing sections 19 and 38 (explosion extinguisher) having the structure shown in FIG. 6 are merely examples, and the present invention is not limited to these.
For example, a structure may be used in which capsules such as thin latex are filled with a liquid fire extinguishing agent such as water, and explosives are suspended at the center thereof. That is, any structure may be used as long as an explosive is placed in the nonflammable liquid layer and the explosive is exploded to instantly make the nonflammable liquid into fine particles.
The layer is not limited to the non-combustible liquid layer, and may be a non-combustible powder layer.

Further, the water or non-combustible liquid used in the explosion-extinguishing method of the present invention may be in the form of jelly made by absorbing water with a super absorbent polymer. In this case, the explosive material is insulated with a non-combustible liquid fire extinguisher and can be safely stored. Explosives can also be made to explode electrically in a non-flammable liquid using an igniter. When an explosive is used as an explosive, it can be used indoors by adjusting the amount of the explosive. The direction and power of the blast may be adjusted depending on the position and shape of the installation location.

With the above structure, when an explosion occurs near the fire point when a fire occurs, non-combustible liquid such as water is instantly atomized by the impact. At this time, the amount of heat generated at the time of explosion does not cause much evaporation in the case of water, so it is not the suffocation effect of the generated vapor, but the suffocation effect due to the expansion of the reaction gas of the explosion and the persistence of the generated fine-particle noncombustible liquid. Achieves reliable fire extinguishing by the effective cooling effect.

As another method of extinguishing the fire extinguishing parts 19 and 38, the flame is generated in the nacelle 2 or the column 32 by filling the nacelle 2 or the column 32 with an inert gas. The fire may be extinguished. Specifically, as the fire extinguishing section 19, 38,
A cylinder filled with compressed inert gas is arranged in the nacelle 2 or the column 32, and an electromagnetic valve (not shown) is attached to the cylinder.

When the flame generation detectors 18, 37 detect a flame, the electromagnetic valve is opened. By releasing the electromagnetic valve, the inert gas compressed in the cylinder is blown out, and the inert gas in the nacelle 2 or the column 32 is filled. As a result, the fire is extinguished by the suffocation effect of blocking oxygen around the fire point. Here, in order to make the choking effect more effective, a lid member or the like for sealing the nacelle 2 or the support column 32 is provided when the electromagnetic valve is released, and the airtightness is enhanced by closing the lid member. Good to do.

Further, in order to prevent the inside of the nacelle 2 from becoming excessively high in pressure due to the inert gas, a relief valve or the like may be provided at a predetermined position of the nacelle 2 to adjust the air pressure inside the nacelle 2.
It should be noted that no person is present inside the nacelle 2 or the pillar 32 during operation of the wind turbine, and human damage is not caused by filling the nacelle 2 or the pillar 32 with an inert gas.

(Details of Fire Extinguishing Process) Next, the contents of the fire extinguishing process according to the present embodiment of the present invention will be described.
FIG. 7 is a flowchart showing the procedure of the fire extinguishing process according to the present embodiment. In the flowchart of FIG.
First, it is determined whether or not a specified value (for example, temperature) has been exceeded (step S1). Here, after waiting for the specified value to be exceeded, if the specified value is exceeded (step S1: Yes),
Next, the power supply system is cut off (step S2). This is to prevent secondary disasters such as short circuits.

Next, the rotation of the wind turbine is stopped (step S3). Even if a fire occurs while the windmill is rotating, the windmill will continue to rotate. Due to this, it is expected that the connection between the blade 1 or 31 and the main shaft 10 or 33 will be lost due to the loss, and the wind turbine itself will pop out vigorously. In addition, the continued rotation of the wind turbine promotes a fire in the generators 14 and 35. Therefore, in order to avoid such a dangerous state, it is extremely important to stop the rotation of the wind turbine quickly and reliably.

Specifically, it is performed by stopping the rotation of the second shaft 20 or the main shaft 33 by the brakes 13 and 36. Alternatively, the rotation of the second shaft 20 or the main shaft 33 may be stopped by passing a current in the opposite direction to the generator 14 or 35.
It may be stopped in combination with 3, 36.
Further, it is preferable to reduce the rotation speed by adjusting the angle of the entire blade 1 or a part of the tip. In any case, it suffices if the rotation of the wind turbine can be stopped more quickly and safely.

Next, it is judged whether or not the rotation speed of the wind turbine is below the specified value (step S).
4). Then, it does not become less than the specified value (step S4 ::
No) If the predetermined time has elapsed in that state (step S5: Yes), the fire extinguishing process is executed (step S6), and an alarm is sent to the management center or the like (step S7), and the alarm is issued using the speaker. Output (step S8).

The first reason for carrying out the fire extinguishing process after stopping the rotation of the wind turbine is that, for example, the brakes 13 and 36 do not operate normally due to the diffusion of the extinguishing agent. . Therefore, priority is given to stopping the rotation of the wind turbine. However,
When the extinguishing agent has little influence on the brakes 13 and 16, it is not always necessary to give priority to the rotation stop of the wind turbine.

As a second reason for carrying out the fire extinguishing process after stopping the rotation of the wind turbine, it is considered that the temperature rise is lowered by stopping the rotation of the wind turbine. In this case, it is considered that there was no fire from the beginning, or the fire was extinguished immediately. Even in such a case, if the fire extinguishing process is carried out, useless extinguishing agents or the like will cause unnecessary damage to the equipment, and the repair cost of the wind turbine generator will be unnecessarily high.

Therefore, when the value becomes equal to or less than the specified value within the predetermined time (step S4: Yes), the control center is notified only of the disconnection of the power supply system and the stop of the rotation of the wind turbine without performing the fire extinguishing process. (Step S9),
The series of processes may be ended.

As described above, according to the present embodiment, the wind turbine that rotates by wind power, the support pillar that supports the wind turbine, the generator that converts rotational energy into electric energy, and the rotation by the wind turbine are provided in the generator. In a driving method for driving a wind turbine generator including a rotating shaft for transmitting and a rotation stopping means for stopping rotation of the rotating shaft, a flame generation detecting step (step S1) for detecting generation of flame in the wind turbine generator, A fire extinguishing step (step S6) of extinguishing the flame based on detection by the flame occurrence detecting step,
Therefore, it is possible to detect the occurrence of the fire by itself and perform the fire extinguishing process, and to extinguish the fire in the wind turbine generator quickly and reliably.

Further, according to the present embodiment, a wind turbine that rotates by wind power, a pillar that supports the wind turbine, a generator that converts rotational energy into electric energy, and a rotating shaft that transmits rotation by the wind turbine to the generator, In a driving method for driving a wind turbine generator equipped with a rotation stopping means for stopping rotation of a rotary shaft, a flame generation detecting step (step S1) for detecting flame generation in the wind turbine and a flame generation detecting step. Since the rotation stop step (step S3) of stopping the rotation of the rotating shaft based on the detection is included, the rotation of the wind turbine can be stopped quickly and surely, and the wind turbine may continue to rotate even after a fire occurs. You can avoid dangerous situations.

Further, according to the present embodiment, a wind turbine that rotates by wind power, a pillar that supports the wind turbine, a generator that converts rotational energy into electric energy, and a rotating shaft that transmits rotation by the wind turbine to the generator.

The rotation of the rotating shaft can be surely stopped without the function being hindered by the extinguishing agent or the like.

Further, according to the present embodiment, the notification step (step S7) of notifying the flame generation information to a predetermined contact based on the detection by the flame generation detection step further includes the person in charge of the fire. The occurrence can be dealt with quickly.

Further, according to the present embodiment, an alarm output step of outputting an alarm sound or an alarm sound indicating the occurrence of flame to the surrounding area of the own apparatus based on the detection by the flame occurrence detection step (step S8).
