Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wind-driven generator and a wind-

The present invention relates to a wind turbine generator and a wind turbine generator.

Recently, renewable energy is attracting attention for reducing greenhouse gas due to global warming, securing energy resources for depletion of oil, and sustainable economic growth while preserving the global environment.

The international community sympathizes with the need for a radical change in the existing economic system based on fossil fuels and is making efforts to transform it into a new paradigm of 'low carbon society'.

Particularly, in Korea, since more than 90% of energy resources are imported and 60% of electric energy is used as fossil fuel, the seriousness is more serious.

In order to solve these problems, researches on alternative energy using solar heat, tidal power, geothermal power, etc. have been conducted. Recently, wind power generating electric energy by driving a generator using wind power has attracted much attention.

Domestic wind power research began as an independent power source for the islands after the oil shock in the 1970s. Since the 1990s, the 160kW pilot complex has been established, and the groundwork for the empirical study and localization of the wind power generation system has resumed, and active research has been conducted recently.

Until the mid-2000s, the overseas wind market was concentrated in a few countries, mainly in Europe such as the US, Germany and Spain. Recently, emerging Asian markets such as China and India have become more prominent.

The primary goal of the global wind turbine system makers is to reduce the cost of energy. The most interesting item for wind power generators, which are the main demand group, is wind power generators with economical efficiency based on high technology and long-term durability.

In recent years, various attempts have been made to satisfy market demands, such as diversification of models, adoption of permanent magnet generators, and development of new concept generators.

In a conventional wind power generator, a rotary shaft of a windmill rotating by a wind speed is directly connected to a speed increasing gear, and a generator is operated by regenerating the rotational force at a speed of about 20 times and transmitting the rotation force to a generator connecting shaft.

However, in such a wind turbine generator, there is a problem in that the gear ratio of the gearbox is fixed and the operation mode is simple, so that it can not cope with changes in wind speed depending on time or season.

In addition, since the resistance of the circuit is matched to the load of the customer connected to the wind power generator, the wind power generator is operated in a state where the brake is applied, which lowers the operation efficiency.

The first generator 120 may include a rotor 121 and a stator 122 that are integrally formed with the wind fan connection shaft 110 and rotate. The electricity generated by the first generator 120 may be supplied to the first battery 191 and charged. The electricity charged in the first battery 191 can be provided for the operation of the electromagnetic clutch 160 and the first to third subordinate electromagnetic clutches 151, 154, 155 that require a relatively large amount of electricity. Here, the cooling fans 111 and 141 may be provided for cooling the inside of the main body 101.

The first gear 125 is integrally formed with the wind power coupling shaft 110 and rotates together with the rotation of the wind power coupling shaft 110.

The second generator 140 receives power from the first gear 125 to produce electricity. The electricity generated by the second generator 140 can be supplied to the second battery 192 and charged. The electricity charged in the second battery 192 is supplied to the controller 180 so that the controller 180 can be operated.

To this end, the first power transmission unit 130 is connected to the first gear 125 to transmit power to the second generator 140. The first power transmission unit 130 may include a driven gear 126 directly connected to the first gear 125 and various gears 131 132 and 133 connected to the driven gear 126. The driven gear 126 is also connected to the second gear 171 through the second power transmitting portion 150 so as to transmit the power to the second gear 171 while allowing power transmission to the second generator 140 .

The generator connection shaft 170 is connected to the wind turbine generator 220 (see FIG. 5) at the rear end of the booster 100. The generator connection shaft 170 may extend outwardly from the inside of the main body 101.

The wind turbine fan connecting shaft 110 and the generator connecting shaft 170 can be connected and disconnected by the electromagnetic clutch 160. The electromagnetic clutch 160 includes a first disk 161 connected to the wind fan connection shaft 110 and a second disk 162 connected to the generator connection shaft 170. The electromagnetic clutch 160 can be operated by receiving electricity from the first battery 191. When the first disk 161 and the second disk 162 are connected to each other, the wind fan connecting shaft 110 and the generator connecting shaft 170 rotate together.

The second gear 171 is integrally formed with the generator connecting shaft 170 and is rotated together with the rotation of the generator connecting shaft 170.

The second power transmission unit 150 is connected to the first gear 125 to transmit power to the second gear 171. The second power transmitting portion 150 includes a driven gear 126 and a first sub-electromagnetic clutch 151 and a second sub-electromagnetic clutch 154 disposed between the driven gear 126 and the second gear 171, A third-portion electromagnetic clutch 155, and a plurality of transmission gears 152, 153, 156, and 157.

The number of revolutions (or speed increasing ratio) of the second gear 171 with respect to the first gear 125 can be adjusted in a plurality of steps by connecting and disconnecting the sub-electromagnetic clutches 151, 154, do.

The second speed sensing sensor 172 senses the rotational speed of the generator connecting shaft 170. For example, the second speed sensing sensor 172 may be an encoder that senses the rotational speed of the generator connecting shaft 170.

The control unit 180 controls the operation of various components such as an electromagnetic clutch. The electromagnetic clutches are normally released. It is important to supply the electric power stably for the operation of the control unit 180. An electromagnetic clutch such as the electromagnetic clutch 160, the first sub-electromagnetic clutch 151, the second sub-electromagnetic clutch 154 and the third sub- When connected, a lot of electricity may be consumed temporarily. In this case, the electricity supplied to the control unit 180 temporarily becomes insufficient, so that an operation error of the control unit 180 may occur.

To this end, the booster 100 of the present embodiment includes two generators of the first generator 120 and the second generator 140, and the electricity generated by the first generator 120 is supplied to the first battery 191, And electricity generated by the second generator 140 is stored in the second battery 192. [ Electricity for operation of the electromagnetic clutches 160, 151, 154 and 155 is supplied from the first battery 191 and electricity for operation of the control unit 180 is supplied from the second battery 192, So that stable operation of the control unit 180 is enabled.

Hereinafter, the operation of the booster 100 of the present invention will be described in detail with reference to FIGS. 1 to 5. FIG. Figs. 2 to 4 are views showing various embodiments in which the wind turbine generator 100 of Fig. 1 is operated. 5 is a diagram showing a configuration of a wind power generator 200 according to an embodiment of the present invention.

When the wind force fan (or the fan) 212 is rotated by wind outside the booster 100, the wind force fan rotation axis 211 rotates accordingly. When the wind turbine fan rotary shaft 211 rotates, the wind fan connecting shaft 110 of the speed changer 100 rotates.

Referring to FIG. 1, as the wind-turbine fan connecting shaft 110 rotates, the first generator 120 rotates to generate electric power. The electricity produced by the first generator 120 is stored in the first battery 191.

The rotation of the first gear 125 is transmitted to the second generator 140 through the first power transmission unit 130. The rotation of the first gear 125 is transmitted to the second generator 140 So that the power can be generated. The electricity produced by the second generator 140 is stored in the second battery 192.

At this time, the first sub-electromagnetic clutch 151 directly connected to the driven gear 126 is in the released state. Accordingly, even if the first gear 125 and the driven gear 126 rotate, this rotational force is not transmitted to the transmission gears 152, 153, 156, 157, 158 and the second gear 171, 170 are not rotated.

The embodiment shown in Fig. 1 is intended to be applied to a state in which the wind velocity is weak and it is difficult to generate substantial wind power. Here, the actual wind power generation refers to a state in which the generator connecting shaft 170 is rotated. In this case, since the first generator 120 and the second generator 140 rotate, the first battery 191 and the second battery 192 can be charged with electricity.

Although the present embodiment is not capable of generating substantial wind power at a first wind speed at which the external wind speed is weak, it is possible to generate electricity required for the operation of the electromagnetic clutch or the control unit 180 of the booster 100, .

2, the first sub-electromagnetic clutch 151 and the third sub-electromagnetic clutch 155 are connected so that the rotational force of the first gear 125 is transmitted to the plurality of transmission gears 152, 157, 158, To the second gear 171 so that the generator connecting shaft 170 can be rotated. In this case, the second sub-electromagnetic clutch 154 is in the released state. Here, the operation of the accelerator (100) such as the connection of the first sub-electromagnetic clutch (151) may be performed according to the measured value by the first speed sensing sensor (115) or the second speed sensing sensor (172). When the first speed sensing sensor 115 senses an increase in the wind speed, the first sub-electromagnetic clutch 151 and the third sub-electromagnetic clutch 155 are connected to allow the generator connection shaft 170 to rotate.

This embodiment corresponds to a case where substantial wind power can be generated at a second wind velocity having a stronger external wind velocity than the case of FIG. In order to generate wind power through the wind power generator 220 connected to the generator connection shaft 170, the number of revolutions of the generator connection shaft 170 must be within a predetermined range due to the rated capacity of each wind power generator 220.

For example, it is assumed that power generation through the wind power generator 220 is possible in the range of 20 to 100 rpm of the generator connecting shaft 170. If the actual wind speed is weak and the number of revolutions of the first gear 125 does not reach 20 rpm, it is necessary to increase the number of revolutions by the gearbox 100. The speed ratio of the second gear 171 to the first gear 125 becomes larger as the external wind speed becomes weaker and the rotational speed of the generator connecting shaft 170 having the same rotational speed as that of the second gear 171 increases It is necessary to bring the number within a certain range. In this embodiment, the speed increasing ratio of the second gear 171 with respect to the first gear 125 can be 20 times, for example, the first step.

3, the first sub-electromagnetic clutch 151 and the second sub-electromagnetic clutch 154 are connected so that the rotational force of the first gear 125 is transmitted to the plurality of transmission gears 152, 153, 156, 157 and 158 to the second gear 171 so that the generator connecting shaft 170 can rotate. In this case, the third subordinate electromagnetic clutch 155 is in the released state.

This embodiment shows the operation of the gearbox 100 at a third wind speed which is higher than that of FIG. 2 in the wind speed of the outside wind. In this case, even if the wind speed of the wind is stronger than that of FIG. 2 and the speed ratio of the second gear 171 to the first gear 125 is made smaller, the number of revolutions of the generator connecting shaft 170 can fall within the rated number of revolutions have. In this embodiment, the speed increasing ratio of the second gear 171 to the first gear 125 can be, for example, ten times as large as the second step.

2 and 3, the second power transmitting portion 150 includes a driven gear 126 and a plurality of sub-electromagnetic clutches 126 disposed between the driven gear 126 and the second gear 171. In this embodiment, (151, 154, 155) and a plurality of transmission gears (152, 153, 156, 157). Accordingly, the number of rotations of the second gear 171 with respect to the first gear 125 can be adjusted in a plurality of steps by connecting and disconnecting the sub-electromagnetic clutches 151, 154, and 155, respectively.

In this way, in the booster 100 of the present embodiment, it is possible to adjust the speed increasing ratio in various stages according to the wind speed of the wind, so that the speed increasing ratio optimized to the wind speed can be realized. Although the present embodiment has exemplarily shown only the incremental increments of the first stage and the second stage, those skilled in the art can easily construct the accelerator having the third incremental speed ratio by arranging various power transmission mechanisms, Such extensions are within the scope of the present invention.

4, the first sub-electromagnetic clutch 151 is released and the electromagnetic clutch 160 is connected so that the first gear 125 and the second gear 171 can rotate at the same rotational speed have.

This embodiment shows the operation of the retainer 100 at the fourth wind speed, in which the wind speed is higher than in the case of FIG. In this case, even if the speed ratio of the second gear 171 to the first gear 125 is set to 1: 1, this corresponds to the case where the rotational speed of the generator connecting shaft 170 falls within the rated rotational speed range.

The first speed sensing sensor 115 senses the rotational speed of the wind turbine connecting shaft 110 and the second speed sensing sensor 172 senses the rotational speed of the generator connecting shaft 170. In the present invention, Speed is detected. The rotational speed ratio measured by the first speed sensing sensor 115 and the second speed sensing sensor 172 is determined by the ratio of the rotational speed of the second gear 171 to the first gear 125 It should match the speed ratio.

However, when the various gears are broken or the slip occurs in the electromagnetic clutches, the rotational speed ratio measured by the first speed sensing sensor 115 and the second speed sensing sensor 172 is different from the rotational speed ratio measured by the first gear 125 The speed ratio of the second gear 171 is different. As described above, when the speed ratio and the speed increasing ratio do not match in the speed changer 100, it is determined that various gears are broken or slip occurs in the electromagnetic clutches, and necessary measures can be taken.

Since the first speed sensing sensor 115 is primarily an indicator of the external wind speed, the speed control device 100 is initially controlled according to the measured value of the first speed sensing sensor 115. When the speed ratio of the gear is adjusted according to the measured value of the first speed sensing sensor 115 and the measured value of the first speed sensing sensor 115 is decreased as the speed increasing ratio of the gear is adjusted, So that it is possible to appropriately cope with the change of the situation.

According to the above-described embodiment, it is possible to provide the booster 100 capable of generating the optimized state according to the wind speed by adjusting the operation of the booster 100 in various stages according to the wind speed of the wind. In this case, the electricity for operating the electromagnetic clutches is supplied from the first battery 191, and the electricity for the operation of the controller 180 is supplied from the second battery 192, 180 and prevents the control unit 180 from operating stably.

Hereinafter, the configuration of the wind power generator 200 of the present invention will be described in detail with reference to FIGS. 1 to 5. FIG.

The wind turbine generator 200 of the present embodiment includes a wind turbine rotation unit 210, a speed reducer 100, a wind turbine 220, a switching unit 230, a resistance control unit 240, a converter 250, 260, and an inverter 270.

The wind fan rotation section 210 includes a fan 212 rotated by the wind and a wind fan rotation axis 211 rotating together with the fan 212 as the fan 212 rotates.

The construction of the booster 100 is as described above with reference to Figs.

The wind turbine generator 220 is connected to the generator connecting shaft 170 of the speed changer 100 to generate electricity by the rotational force of the wind fan rotation section 210.

The converter 250 converts DC energy generated by the wind power generator 220 into DC energy.

The charging device 260 can receive power from the converter 250 and supply the charged electricity to the inverter 270.

The inverter 270 converts the direct current energy stored in the charging device 260 into alternating current energy and supplies it to the power transmission device 280 so that the power transmission device 280 supplies the electric energy to the consumer 290 .

The switching unit 230 may connect (short-circuit) and release (open) the wind power generator 220 and the converter 250 in response to the control signal.

The resistance adjustment unit 240 is disposed between the wind power generator 220 and the converter 250 and adjusts the resistance value in response to the control signal.

The resistance adjusting unit 240 may include a plurality of resistance control units 241, 242, and 243 connected in series to each other and each of which can adjust a resistance value in response to a control signal. For example, each of the resistance control units 241, 242, and 243 includes resistors 241a, 242a, and 243a having a predetermined resistance value, and a switching device (not shown) connected in parallel with the resistors 241a, 242a, and 243a 242b and 243b may be comprised of a relay or a semiconductor power device SSR. Each of the resistance control units 241, 242 and 243 may be a 3-phase And can be operated at the same time.

The operation of the switching unit 230 and the resistance adjusting unit 240 may be performed by the control unit 180 disposed in the booster 100 or may be performed by a separate control unit disposed in the inverter 270. [ For example, the control unit 180 of the speed changer 100 directly outputs a control signal for controlling the operation of the switching unit 230 and the resistance control unit 240 according to the measured value of the second speed sensing sensor 172 Or through another control unit. The arrangement of the control unit for controlling the switching unit 230 and the resistance adjusting unit 240 does not limit the present invention.

The switching unit 230 is in a released state when substantial wind power is not generated, and is connected when substantial power generation is started. When the switching unit 230 is connected, electricity can be supplied to the customer 290.

As the usage load of the customer 290 increases, the rotational speed measured by the second speed sensing sensor 170 decreases. The control unit 180 of the speed controller 100 performs control such as adjusting the speed ratio according to the measured value of the second speed sensor 170. If the control unit 180 determines that the actual speed is difficult to be generated by the control, ) Is released to stop the power generation. When the measured value of the second speed sensing sensor 170 is increased to an appropriate speed at which the electric power can be generated by the disconnection of the switching unit 230, the switching unit 230 is connected again to generate electric power.

The resistance adjusting unit 240 may adjust the resistance value between the wind power generator 220 and the converter 250. Since the resistance control unit 240 is composed of a plurality of resistance control units 241, 242 and 243, the resistance values of the respective resistance control units 241, 242 and 243 are controlled according to the situation, Thereby enabling efficient operation.

For example, in a general situation, each of the resistance control units 241, 242 and 243 is connected to resistors 241a, 242a and 243a by the switching elements 241b, 242b and 243b being opened. The total resistance value of the resistance adjusting unit 240 may be reduced step by step if the resistance value of the resistance adjusting unit 240 is shortened. A large amount of electricity can be supplied. When a large amount of electricity is supplied to the customer 290, the effect of suppressing the rotation of the wind power generator 220 is generated.

For example, when the measured value of the second speed sensing sensor 172 is increased to a predetermined value or more due to an increase in the external wind speed or the like, various problems occur, such as the parts of the wind power generator 200 being damaged. In this case, it is necessary to suppress the rotation of the generator and to keep the measured value of the second speed sensing sensor 172 below a predetermined value. To this end, the resistance regulator 240 controls the switching elements 241b, 242b, and 243b Short circuiting step by step.

When the switching elements 241b, 242b and 243b are short-circuited and the resistance value of the resistance regulating part 240 is reduced, a large amount of electricity is supplied to the customer 290 to cause a brake effect to suppress the rotation of the wind power generator 220 . Accordingly, it is possible to prevent the components of the wind power generator 200 from being damaged. This problem can also be achieved by adjusting the speed ratio of the speed reducer 100.

According to the wind turbine generator 200 of the present invention, it is possible to control the rate of increase of the speed ratio, the control of the resistance controller 240 and the switching unit 230 according to external variables such as the external wind speed and the usage load of the customer 290, It is possible to artificially and intelligently maintain the optimum operation mode.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
