Exemplary embodiments of a wind turbine generator operating method and a wind turbine generator according to the present invention will be explained below in detail with reference to the accompanying drawings.
[0013]
(Configuration of wind power generator)
There are two types of wind turbine generators: a horizontal axis wind turbine whose rotation axis is horizontal to the ground and a vertical axis wind turbine whose rotation axis is perpendicular to the ground. FIG. 1 and FIG. 2 are a front view and a side view showing an external 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 constituting the wind turbine, 2 is a nacelle, 3 is a blade 1 and a nacelle 2 It is a support for supporting.
[0014]

In FIG. 3, 10 is a main shaft, 11 is a main bearing that receives the main shaft 10, 12 is a speed increaser (gear box) that changes the rotational speed of the main shaft 10, and 13 is connected to the speed increaser 12. The brake for stopping the rotation of the second shaft 20 is performed, 14 is a generator for generating electric energy by the rotation of the second shaft 20, 15 is a nacelle opening / closing portion for opening and closing the nacelle, and 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. Yes, 19 is a fire extinguishing unit that extinguishes the flame generated in the nacelle 2.
[0015]
Further, although not shown in the figure, a notification unit for notifying the generation of flame information to a predetermined contact, for example, a management center, a fire department, the police, or the like based on detection by the flame generation detection unit 18 is provided. The notification unit is configured by, for example, a wireless transmission device, and automatically transmits a signal indicating the occurrence of a flame. Similarly, although not shown in the figure, an alarm sound (siren) or an alarm sound (for example, “evacuate quickly from this area because it is dangerous.” Alarm output unit (speaker) is installed. For example, the alarm output unit may be installed at any height of the column 3.
[0016]
In such a configuration, 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 electricity by the accelerated rotation. Further, the brake 13 employs a disk-type brake and stops the rotation of the second shaft 20 as necessary. Thereby, the rotation of the main shaft 10 is also stopped, and thus the rotation of the blade 1 is stopped.
[0017]
Moreover, the flame generation detection part 18 is arrange | positioned in the nacelle 2, and is comprised by a temperature sensor, a smoke sensor, an ultraviolet sensor, etc. In any case, it can be determined that a flame has occurred when the predetermined value is exceeded. Moreover, you may be comprised by the electric current or voltage value measuring device of the generator 14, a wind speed measuring device, the rotation speed measuring device of the main axis | shaft 10 or the 2nd axis | shaft 20, etc. In this case, the occurrence of a flame is not directly detected, but it may be determined that an abnormal situation in which a flame is likely to occur has occurred, and a fire extinguishing or stopping operation is started. Moreover, when the flame generation detection part 18 is each said measuring device, it does not necessarily need to be arrange | positioned in the nacelle 2. FIG. Further, the flame generation detection unit 18 may be a combination of the above sensors or a combination of any of the above sensors and the above measuring devices. As a result, the occurrence of a flame can be detected more accurately.
[0018]
Similarly, the fire extinguishing unit 19 is also arranged in the nacelle 2 and executes a fire extinguishing process based on detection by the flame occurrence detection unit 18. Therefore, in order to operate the fire extinguishing part 19, it is not necessary for the administrator to operate the fire extinguishing part 19 remotely, and thus the fire extinguishing is performed quickly. A detailed description of the fire extinguishing method will be described later.
[0019]
In FIG. 3, the fire extinguishing unit 19 is provided only at one place in the nacelle 2. However, the present invention is not limited to this and may be provided at a plurality of places. In that case, it is good to provide separately so that it may correspond to each of each structure part (speed increaser 12, brake 13, generator 14). Furthermore, it is more effective if the fire extinguishing method of the fire extinguishing unit 19 is made different depending on the characteristics of each component (for example, the gearbox that is the gearbox 12 uses a lot of oil).
[0020]
FIG. 4 is an external view showing an appearance of a wind power generator of a Darrieus type windmill as an example of a vertical axis windmill. As shown in FIG. 4, in a wind power generator of a Darrieus type windmill as an example of a vertical axis windmill, 31 is a blade constituting the windmill, and 32 is a support for supporting the blade 31.

Each of the above-described components is the same as that of the wind turbine generator of the propeller type windmill shown in FIGS.
[0023]
(Contents 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. If any one of the following is achieved, extinguishing is possible. First, keep the flame away from the combustible material that is burning. Secondly, combustibles around the fire point are prevented from liquefying and vaporizing energy from the flame and changing into a combustible gas (cooling effect). Third, it blocks oxygen around the fire point (suffocation effect).
[0024]
In general, in the event of a fire, combustibles around the flame receive energy from the flame, become liquefied and vaporized, become flammable gas, and ignite / combust. The energy required when the combustible material at this time is liquefied and vaporized to become a combustible gas is called activation energy. In the event of a fire, water is discharged to the flame and attempts to extinguish the water by evaporating the water around the fire point, taking away the thermal energy of the flame by the latent heat of evaporation of the water, making the energy less than the activation energy, and combustible materials around the flame This is intended to prevent the gasification of gas (cooling effect).
[0025]
Considering this effect, the explosives can be safely held under normal conditions, and in the event of a fire, the explosives are exploded in a fire extinguisher near the fire point. It is very effective in a wide range by keeping the flame away from combustible materials, causing a local suffocation effect around the fire point, and at the same time making the fire extinguisher around the explosive material atomized by the explosion reaction and reaching the fire point A fire extinguishing agent is sprayed in a short time to take out the heat energy of the flame and extinguish the fire. In addition, a suffocating effect by water vapor is expected, and the extinguishing agent covers the combustible material after the fire extinguishing, thereby preventing the possibility of relapse.
[0026]
In addition, the extinguishing agent can be atomized in a wide range near the fire point, reach it, and can be extinguished in a very small amount, and the amount of explosives can be reduced compared to the method of extinguishing only with the blast, nacelle This is a fire extinguishing method that can be applied to various types of fires with little risk of the 2 or the support 32 being damaged by an explosion.
[0027]
FIG. 6 is an explanatory diagram showing the structure of an explosion digester as the fire extinguishing section 19 or 38. In FIG. 6, reference numeral 40 denotes a ball-shaped soft plastic container, and the inside of the container 40 is filled with an incombustible liquid 41 such as a digestive agent. A ball-shaped hard plastic container 42 is disposed in the layer of the incombustible liquid 41, the inside of the container 42 is filled with an explosive 43, and the center of the explosive 43 is filled with an ignition agent 44. Yes.
[0028]
One end of a high speed lead wire 46 penetrating the plastic pipe 45 is connected to the ignition powder 44, and the other end of the high speed lead wire 46 is connected to an ignition powder 47 mounted on the outer surface of the container 40. This plastic pipe 45 is used to shut off the high-speed conduit 46 from the incombustible liquid 41. In order to guide the fire igniting the ignition powder 47 to the explosive 43 using the high-speed conduit 46, the plastic pipe 45 The inner diameter needs to be 1 mm or more.
[0029]
In the fire extinguishing sections 19 and 38 (explosion extinguisher) having the above-described structure, the ignition propellant 47 is ignited, so that the fire propagates through the high-speed lead wire 46 and ignites the ignition propellant 44 disposed at the center of the explosive 43. By doing so, the explosive 43 explodes. Due to the generation / diffusion of the inert gas generated by the explosion and the blast, the hard plastic container 42 ruptures into fine pieces and diffuses, and the soft plastic container 40 is destroyed. The incombustible liquid 41 filled in the container 40 by the diffusion of the gas or the blast is instantly atomized and diffused.
[0030]
Therefore, by exploding an explosion-extinguisher having the above structure near the fire point at the time of the fire, the flame is blown out by the diffusion of the inert gas generated at that time and the blast. You will get the combustibles left after the blown-out flame. As a result, not only the flame is blown out by the explosion of the explosive 43, but even if fresh air sufficiently containing oxygen is blown again in the vicinity of the original fire point, it is burned by the incombustible liquid that has been atomized, so that there is a concern that it will relapse. Disappears.
[0031]
As the explosive 43, for example, an explosive such as “nitrocellulose” or “sodium azide + CuO” is used, and as the igniting agent 44 and the igniting agent 47, for example, “boron + lead peroxide” and “tricinate”, etc. Is used. In order to ignite and explode the explosive material, an igniting agent 44 in an amount of 1 to 10% of its weight is required. Moreover, when the explosive 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 proceeds in that direction. Since the effect of making fine particles is difficult to occur, in order to prevent this, the container 42 is provided with many uniform grooves so that the container 42 is crushed into uniform fine fragments.
[0032]
As described above, by providing the igniting agent 47 on the outer surface of the container 40, when the fire extinguishing unit 19, 38 (explosion extinguisher) is in the flame in the event of a fire, the igniting agent 47 is ignited by the flame. Since the explosive 43 is ignited and explodes through the high-speed lead 46, simply installing a fire extinguisher at the place where the fire occurred will cause the explosive 43 to automatically explode, blow out the flame, and not burn The combustible liquid 41 is made into fine particles, and the combustible material remaining after the flame is blown out with the finely divided incombustible liquid 41 is scooped. Therefore, 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 a flame generation detection unit. Of course, you may make it ignite the ignition agent 47 with the detection signal by a flame generation | occurrence | production detection part.
[0033]
The fire extinguishing units 19 and 38 (explosion extinguishers) having the structure shown in FIG. 6 are merely examples, and the present invention is not limited thereto. For example, a structure in which a capsule such as a thin latex is filled with a liquid fire extinguisher such as water and an explosive is suspended at the center thereof. That is, any structure may be used as long as explosives are arranged in the incombustible liquid layer and the explosives are exploded to instantly make the incombustible liquid fine particles. Moreover, it is not limited to a nonflammable liquid layer, A nonflammable powder layer may be sufficient.
[0034]
In addition, the water or incombustible liquid used in the explosion-extinguishing method of the present invention may be in the form of a jelly absorbed by a highly water-absorbing polymer. In this way, the explosives are insulated with a nonflammable liquid fire extinguisher and can be stored safely. Explosives can also be made to explode in an incombustible liquid using an igniter. When explosives are used for explosives, they can be used indoors by adjusting the amount of explosives. The direction and power of the blast should be adjusted according to the position and shape of the installation location.
[0035]
With the above structure, when an explosion occurs in the vicinity of a fire point at the time of fire, 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 evaporate much in the case of water, so it is not the suffocation effect of the generated steam, but the suffocation effect associated with the expansion of the reaction gas of the explosion and the sustainability of the generated particulate incombustible liquid Reliable fire suppression is achieved by the effective cooling effect.
[0036]
In addition, as another fire extinguishing method for the fire extinguishing units 19 and 38, the flame is extinguished by filling the nacelle 2 or the support column 32 with an inert gas in response to the occurrence of a flame in the nacelle 2 or the support column 32. You may do it. Specifically, as the fire extinguishing units 19 and 38, a cylinder filled with compressed inert gas is disposed in the nacelle 2 or the support column 32, and an electromagnetic valve (not shown) is attached to the cylinder.
[0037]
When a flame is detected by the flame generation detection units 18 and 37, the electromagnetic valve is released. 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 support column 32 is filled. This achieves quenching by the suffocation effect that blocks oxygen around the fire point. Here, in order to make the suffocation effect more effective, when the electromagnetic valve is released, a lid member for sealing the nacelle 2 or the support column 32 is provided and the lid member is closed to enhance the sealing performance. Good.
[0038]
Further, in order to prevent the inside of the nacelle 2 from becoming an excessively high pressure with an inert gas, it is preferable to provide a relief valve or the like at a predetermined location of the nacelle 2 to adjust the atmospheric pressure in the nacelle 2. In the nacelle 2 or the support column 32, no person is present during the operation of the windmill, and no personal damage is caused by filling the nacelle 2 or the support column 32 with an inert gas.
[0039]
(Contents of fire fighting treatment)
Next, the contents of the fire extinguishing process according to this 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. 7, first, it is determined whether or not a specified value (for example, temperature) has been exceeded (step S1). Here, after exceeding the specified value, if the specified value is exceeded (step S1: Yes), the power supply system is then disconnected (step S2). This is to prevent secondary disasters such as short circuits.
[0040]
Next, the rotation of the windmill is stopped (step S3). Even if a fire breaks out with the windmill rotating, the windmill will continue to rotate. As a result, it is expected that the connection between the blade 1 or 31 and the main shaft 10 or 33 is lost due to disappearance and the windmill itself jumps out vigorously. Moreover, a fire in the generators 14 and 35 will be promoted because a windmill continues rotating. Therefore, in order to avoid such a dangerous state, it is extremely important to stop the rotation of the windmill quickly and reliably.
[0041]
Specifically, it is performed by stopping the rotation of the second shaft 20 or the main shaft 33 by the brakes 13 and 36. Further, the rotation of the second shaft 20 or the main shaft 33 may be stopped by supplying a current in the opposite direction to the generator 14 or 35, or may be stopped by using the brakes 13 and 36 together. . Furthermore, it is preferable to reduce the rotational speed by adjusting the angle of the entire blade 1 or a part of the tip. In any case, it is sufficient that the rotation of the windmill can be stopped more quickly and safely.
[0042]
Next, it is determined whether or not the value has become equal to or less than the specified value due to the stop of the rotation of the windmill (step S4). If the predetermined time has not passed (Step S4 :: No) in that state (Step S5: Yes), a fire extinguishing process is executed (Step S6) and an alarm is transmitted to the management center or the like. (Step S7), and further an alarm is output using a speaker (Step S8).
[0043]
The first reason why the fire extinguishing process is performed after the rotation of the windmill is stopped is because, for example, the brakes 13 and 36 may not operate normally due to diffusion of the digestive agent. Therefore, priority is given first to stopping the rotation of the windmill. However, when the extinguishing agent has little influence on the brakes 13 and 16, it is not always necessary to give priority to stopping the rotation of the windmill.
[0044]
As a second reason for performing the fire extinguishing process after stopping the rotation of the windmill, a case where the temperature rise is lowered by stopping the rotation of the windmill can be considered. In this case, it is possible that it was not a fire from the beginning or was extinguished immediately. Even in such a case, if the fire extinguishing process is performed, the digestive agent or the like may cause unnecessary damage to the equipment, and the repair cost of the wind power generation apparatus will be unnecessarily high.
[0045]
Therefore, when it becomes less than or equal to the specified value within a predetermined time (step S4: Yes), the management center or the like is notified only about the disconnection of the power system and the stoppage of the windmill without performing the fire extinguishing process (step S9). ), A series of processes may be terminated.
[0046]
As described above, according to the present embodiment, the wind turbine rotated by wind power, the support supporting the wind turbine, the generator for converting rotational energy into electric energy, and the rotating shaft that transmits the rotation by the wind turbine to the generator. A flame generation detecting step (step S1) for detecting the occurrence of a flame in the wind power generator, and a flame occurrence detection. A fire extinguishing process (step S6) that extinguishes the flame based on detection by the process, so that the fire can be detected by itself and fire extinguishing treatment can be performed quickly and reliably in the wind power generator Can be extinguished.
[0047]
In addition, according to the present embodiment, a windmill that is rotated by wind power, a support that supports the windmill, a generator that converts rotational energy into electrical energy, a rotary shaft that transmits rotation by the windmill to the generator, and the rotational shaft In a driving method for operating a wind turbine generator having a rotation stop means for stopping rotation, a flame generation detection step (step S1) for detecting the occurrence of flame in the wind turbine generator and detection by the flame generation detection step A rotation stopping step (step S3) for stopping the rotation of the rotating shaft, and therefore, a dangerous state that may occur by stopping the rotation of the windmill quickly and reliably and continuing the rotation of the windmill even after the occurrence of a fire. Can be avoided.
[0048]
In addition, according to the present embodiment, a windmill that is rotated by wind power, a support that supports the windmill, a generator that converts rotational energy into electrical energy, a rotary shaft that transmits rotation by the windmill to the generator, and the rotational shaft In a driving method for operating a wind turbine generator having a rotation stop means for stopping rotation, a flame generation detection step (step S1) for detecting the occurrence of flame in the wind turbine generator and detection by the flame generation detection step A rotation stopping step (step S3) for stopping the rotation of the rotating shaft, and a fire extinguishing step (step S6) for extinguishing the flame after stopping the rotation of the rotating shaft by the rotation stopping step. Thus, the rotation of the rotating shaft can be reliably stopped without hindering the function.
[0049]
In addition, according to the present embodiment, since it includes the notification step (step S7) for notifying the predetermined contact address of the flame occurrence information based on the detection by the flame occurrence detection step, Can be dealt with quickly.
[0050]
In addition, according to the present embodiment, since an alarm output step (step S8) for outputting an alarm sound or an alarm sound indicating the occurrence of a flame to the surrounding area of the device itself is further included based on the detection by the flame occurrence detection step. By calling attention, secondary disasters due to fire can be prevented.
[0051]
