However, in the invention disclosed in Patent Document 1, the storage battery used to assist the rotation of the windmill stores the power generated by the wind power generation, and requires an inverter and a bidirectional buck-boost converter on the output side of the generator. Therefore, there is a problem that the circuit is complicated and the control is also complicated.
Further, in the invention disclosed in Patent Document 2, an auxiliary device for assisting the rotation of the wind turbine is provided separately to eliminate complication of the circuit. is rotating at a low speed or is not rotating, and the activation of the rotation assist control means is the generated power storage that controls the DC voltage after rectifying the AC voltage of the generator to be constant. It is executed when the direct current value flowing through the means is low or when the direct current is flowing from the storage battery. Therefore, there is a problem that it is unclear whether or not it is possible to supply electric power from the storage battery and generate more power than the supplied electric power by activating the rotation assist control means, that is, whether or not the power generation efficiency is improved.
Furthermore, in the invention disclosed in Patent Document 3, an invention is disclosed in which electric power obtained from solar power generation is directly supplied to a motor that assists driving a wind turbine for wind power generation or a blower that generates wind for wind power generation. Although it is possible to avoid complication of the circuit for rotation assist of , in this invention, the purpose is to rotate the wind turbine even at a wind speed at which the wind turbine does not originally rotate, and the efficiency of wind power generation cannot be improved. The problem was that it was very likely.
The present invention has been made in response to such conventional circumstances, and enables simultaneous execution of wind power generation and photovoltaic power generation, does not require a complicated circuit, improves the efficiency of wind power generation, and provides a stable supply of electric power. The object is to provide a possible hybrid power generation system.

In order to achieve the above object, a hybrid power generation system according to a first aspect of the present invention includes a solar power generation device that includes a solar panel and performs solar power generation, and a wind power generator that rotates blades with wind power to generate power. A hybrid power generation system having a power generation device, wherein the solar power generation device includes a storage battery that stores power generated by the solar panel, and the wind power generation device supplies the power stored in the storage battery to the power generator. A power supply control device is provided for controlling the power supply to drive the motor as a motor, wherein the power supply control device defines the frictional force as Fx, which is the rotational force received by the blade when the frictional force fx applied to the rotor shaft including the blades is Let Fd be the rotational force when fx is the same static friction force as the dynamic friction force fd, and let Fs be the rotational force when the friction force fx is the maximum static friction force fs. It is characterized in that the electric power capable of generating the rotational force of the difference is supplied to the generator to drive it as the motor.
In the hybrid power generation system configured as described above, the storage battery supplies electric power to produce the insufficient rotational force of the rotational force necessary for the frictional force fx applied to the rotor shaft to exceed the maximum static frictional force fs to start rotation. act to
The frictional force applied to the rotor shaft in the present application means the frictional force generated against the bearing of the rotor shaft and the magnetic field of the generator. Therefore, the start of rotation of the rotor shaft is synonymous with the start of power generation by the wind turbine generator.

A hybrid power generation system of a second invention is characterized in that in the first invention, the power supply control device does not supply the electric power to the generator when the Fx is lower than the Fd or higher than the Fs. It is something to do.
In the hybrid power generation system configured as described above, in addition to the effect of the first invention, when the rotational force Fx is lower than the rotational force Fd, even if the power supply control device supplies electric power from the storage battery to the generator, Since power cannot be generated unless power is supplied to the generator, and there is a possibility that the amount of power consumption is greater than the amount of power generated, the power supply control device is controlled so as not to supply power to the generator.
On the other hand, when the rotational force Fx exceeds the rotational force Fs, even if the power supply control device does not supply power to the generator, the blades are rotated by the wind force, so control is performed so as not to supply power.

A third invention is a hybrid power generation system according to the first or second invention, wherein the Fx, the Fd, and the Fs are obtained in advance using the wind direction and wind speed as parameters, and the The power supply control device is characterized by calculating the Fx, the Fd and the Fs using the output of the anemoscope and the output of the anemometer.

Although yaw control is not described in this application, actual calculations of Fx, Fd, and Fs are similarly possible even when yaw control is performed using a wind vane. When performing yaw control, the blades are generally always facing upwind and receive the wind from the front. Calculation is possible with the output from In addition, "computation" using the output of the anemometer and the anemometer means, of course, when obtaining the actual Fx, Fd and Fs from functions such as theoretical formulas and empirical formulas, for example, using the wind direction and wind speed as parameters in advance The concept also includes the case of extracting the actual Fx, Fd and Fs corresponding to the output values of the anemoscope and anemometer from the obtained data table of Fx, Fd and Fs.

A fourth invention is a hybrid power generation system according to any one of the first to third inventions, wherein the solar panel is installed on an outer wall of a tower that supports the generator of the wind turbine generator. It is characterized.
In the hybrid power generation system with the above configuration, in addition to the effects of any one of the first to third inventions, by installing the solar panel on the outer wall of the tower, it is also possible for the existing wind turbine generator. There is no need to secure a new solar panel installation site. Moreover, in offshore wind turbine generators, it acts to suppress salt damage and corrosion when solar panels are installed on the sea.

A fifth invention is a hybrid power generation system according to the fourth invention, wherein the solar power generation device has a light receiving surface control device capable of controlling the direction of the light receiving surface of the solar panel according to time. and
In the hybrid power generation system configured as described above, in addition to the effects of the fourth invention, the light receiving surface control device controls the direction of the light receiving surface of the solar panel so as to efficiently receive sunlight in accordance with the time.

In the hybrid power generation system of the first invention, the static friction force fx applied to the rotor shaft exceeds the maximum static friction force fs and the electric power for compensating for the insufficient rotational force of the rotational force required to start rotation is stored in the storage battery. Since the power is supplied from the blades, it is possible to generate power by rotating the stopped blades, and it is possible to save the power to be supplied to the minimum required, and to increase the power generation efficiency of the entire hybrid power generation system. is. In addition, the electric power generated by the wind power generation is not stored in the storage battery, and the electric power generated only by the solar power generation device is used to assist the rotation, so the circuit configuration is not complicated, and operation and management are easy.

In the hybrid power generation system of the second invention, in addition to the effects of the first invention, power is not supplied when Fx is less than Fd. In this case, it is possible to save the power stored in the storage battery by not supplying power, and since power is not supplied even when Fx exceeds Fs, rotation is possible without power supply from the storage battery. In some cases, it is possible to save power stored in the storage battery by not supplying power. Therefore, it is possible to increase the power generation efficiency of the entire hybrid power generation system.

In the hybrid power generation system which is the third invention, in addition to the effects of the first or second invention, Fx, Fd, and Fs are obtained in advance using the wind direction and wind speed as parameters, and the power supply control device uses the wind vane and the wind speed By calculating the actual Fx, Fd, and Fs using the output of the meter, it is possible to perform more accurate power supply control, and therefore, it is possible to stably increase the power generation efficiency of the entire hybrid power generation system. is.

In the hybrid power generation system, which is the fourth invention, in addition to the effects of any one of the first to third inventions, the installation location of the solar panel is set on the outer wall of the tower, so that the installation location of the solar panel is reduced. There is no need to provide it, and it can be easily installed to an existing wind power generator or an offshore wind power generator.

FIG. 4 is a flowchart of control by the power supply control device of the hybrid power generation system according to the embodiment of the present invention;

A hybrid power generation system according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG.
FIG. 1 is a schematic external view of a hybrid power generation system according to an embodiment of the present invention, and FIG. 2 is a system configuration diagram of the hybrid power generation system. 1 and 2, the hybrid power generation system 1 is composed of a wind power generator 2 and a solar power generator 7. The wind power generator 2 is installed at the top of a tower 6 and a nacelle 5 extending from inside the nacelle 5. and a plurality of blades 3 radially arranged around a hub 4 provided at the tip of the rotor shaft 10 .
Inside the nacelle 5, a gearbox 11 for increasing the rotational speed of the blades 3 on the rotor shaft 10, and a generator 12 for converting kinetic energy into electrical energy at a rotational speed suitable for power generation by the gearbox 11. is connected.
Electric power generated by the generator 12 is sent to the electric power system 19 through a transformer, a system stabilizer, and the like.
The wind turbine generator 2 also includes an anemometer 15 and an anemoscope 16 (neither of which is shown in FIG. 1), the outputs of which are transmitted to the generator control device 13 and the power supply control device 14. . The generator control device 13 receives the output of the anemometer 15, receives the rotation speed of the rotor shaft 10 and the output of the generator 12 from the generator 12, and further receives an output request from the electric power system 19 to generate power. It sends a control signal to the machine 12 . In addition, when a yaw control device (not shown; optional component) for directing the blades 3 to the windward direction is provided at the bottom of the nacelle 5 or the like, the generator control device 13 outputs the output from the wind vane 16 is used to transmit a control signal to the yaw control device to control the blade 3 to face upwind.

Before describing the power supply control device 14, the solar power generation device 7 will be described.
As shown in FIG. 2, the photovoltaic power generation device 7 includes a solar panel 8 that receives sunlight to generate power, a storage battery 17 that stores the generated power, and a DC power stored in the storage battery 17 that converts to AC power. An inverter 18 for conversion and a light receiving surface control device 20 (an optional component) capable of controlling the direction of the light receiving surface of the solar panel 8 according to the time are provided.
Moreover, as shown in FIGS. 1(a) and 1(b), the solar panel 8 is installed on the outer wall of the tower 6 of the wind turbine generator 2 via support arms 9. As shown in FIGS. Although the solar panels 8 are installed only on a part of the outer wall of the tower 6 in FIG. It may be installed in a small area. In addition, when installed on a part of an outer wall, a light receiving surface control device 20 that makes the support arm 9 movable is provided so that the light receiving surface of the solar panel 8 can efficiently receive sunlight depending on the time of day. It may be possible to perform control following the position and altitude of the sun.
The electric power stored in the storage battery 17 is sent to the electric power system 19 through the inverter 18 and the transformer, the system stabilizer, etc., like the electric power generated by the wind power generation.
In addition, the electric power stored in the storage battery 17 is supplied to the generator 12 as a motor through the power supply control device 14 based on certain conditions when the blades 3 are stopped. It is supplied to the generator 12 for rotation.

Next, referring back to FIG. 2, the power supply control device 14 will be described.
First, the outputs from the anemometer 15 and the anemoscope 16 are assumed in advance, and using these output values as parameters, the rotational forces Fx, Fd, and Fs that the blade 3 receives while it is stopped are obtained theoretically or from test results. back. The power supply control device 14 uses the outputs of the anemometer 15 and the anemoscope 16 and these Fx, Fd, and Fs obtained in advance to calculate the rotational forces Fx, Fd, and Fs actually received by the blades 3 .

A specific description will be given with reference to FIGS. 3 and 4. FIG.
FIG. 3 is a conceptual diagram showing the relationship between the rotational force received by the blades of the wind power generator and the static and dynamic friction forces acting on the rotor shaft of the generator. FIG. 4 is a conceptual diagram showing the relationship between the wind velocity that the blade receives and the rotational force that the blade receives.
In FIG. 3 , the horizontal axis represents the rotational force applied to the blades 3 and the vertical axis represents the frictional force applied to the rotor shaft 10 of the generator 12 . In this figure, the term "rotational force" expresses, for the sake of convenience, the force that the blades 3 are subjected to when they are not rotating, and that the blades 3 are trying to rotate.
In FIG. 3, the symbol Fx is the rotational force that the blade 3 receives from the wind force while it is stopped. is expressed as the product of The symbol Fd is a value obtained by dividing the dynamic friction force fd generated on the rotor shaft 10 when the blades 3 are rotating by the static friction coefficient μ, and when the blades 3 are stopped, the dynamic friction force fd on the rotor shaft 10 is the rotational force received by the blade 3 when generating the same static friction force fd as . Symbol Fs is the rotational force that the blades 3 receive when the maximum static friction force fs is generated on the rotor shaft 10 of the generator 12 .
The symbol Fa is the difference between the rotational force Fx that the blade 3 receives while it is stopped and the rotational force Fs that the blade 3 receives when the maximum static friction force fs is generated on the rotor shaft 10 . The rotation of the blades 3 is assisted by supplying power generated by the solar power generation device 7 to the power generator 12 via the power supply control device 14 from the storage battery 17 that stores the power generated by the photovoltaic power generation device 7 so as to compensate for this difference Fa.

Next, in FIG. 4 , the horizontal axis indicates the wind speed that the blades 3 receive, and the vertical axis indicates the rotational force that the blades 3 receive.
Since the wind pressure generated by the stopped blades 3 receiving the wind is proportional to the square of the wind speed, the rotational force that the blades 3 receive is proportional to the square of the wind speed that the blades 3 receive. In FIG. 4, the force applied to the blade 3 while it is stationary is expressed as the "rotational force" for the sake of convenience as described above. The rotational force in FIG. 4 can be calculated as a quadratic curve as shown if the wind speed received by the blade is known.
In FIG. 4, vx is the wind speed received by the blades 3, and the wind speed vd is the same static friction force fd as the dynamic friction force fd (see FIG. 3) generated on the rotor shaft 10 of the generator 12 when the blades 3 are rotating. is the wind speed required to give the blade 3 rotational force Fd (see FIG. 3) generated when the blade 3 stops, and the wind speed vs is the blade 3 rotational force Fs (see FIG. 3) required to give is the wind speed.
In the hybrid power generation system 1, the wind direction and wind speed with respect to the blades 3 are used as parameters, and the rotational force Fd of the rotor shaft 10, the rotational force Fd that provides the same static friction force as the dynamic friction force fd, and the maximum static friction The rotational force Fs that gives the force fs is obtained, and based on the outputs from the anemometer 15 and the anemoscope 16 provided in the hybrid power generation system 1, the power supply control device 14 calculates the previously obtained Fx, Fd, and Fs to calculate the actual Fx, Fd and Fs. Specifically, Fx, Fd, and Fs obtained in advance are used as functions of the wind direction and wind speed, and the actual wind direction and wind speed, which are the outputs of the anemometer 15 and the anemoscope 16, are input to the function. Compute Fx, Fd and Fs.
The previously obtained Fx, Fd and Fs may be stored in the power supply control device 14 as functions such as theoretical formulas and empirical formulas, or may be stored in the power supply control device 14 in the form of a data table. Alternatively, when wind direction data and wind speed data are determined, Fx, Fd and Fs may uniquely correspond to each other.

Furthermore, when the hybrid power generation system 1 includes a yaw control device to perform yaw control, the generator control device 13 uses the output from the anemoscope 16 to transmit a control signal to the yaw control device. Even in this case, the actual calculations of Fx, Fd and Fs are possible. When performing yaw control, the blades are generally always facing upwind and receive the wind from the front. , the output from the anemometer 15 can be used to calculate the actual Fx, Fd and Fs.
The power supply control device 14 also calculates the difference Fa between the calculated Fs and Fx, and receives from the storage battery 17 of the photovoltaic power generation device 7 power supply capable of assisting the rotational force corresponding to this difference Fa. The power supply control device 14 sends this electric power to the generator 12, and the generator 12 generates a rotational force corresponding to the difference Fa with respect to the rotor shaft 10, causing the rotor shaft 10 and the blades 3 to rotate.
By assisting the rotation of the blades 3 in this way to compensate for only the insufficient rotational force, the power generated by the solar power generation device 7 is saved while the power generation by the wind power generation device 2 is promoted. The power generation efficiency of the hybrid power generation system 1 as a whole is improved.

Next, specific control by the power supply control device 14 will be described with reference to FIG. FIG. 5 is a flowchart of control by the power supply control device of the hybrid power generation system according to the embodiment of the present invention.
In FIG. 5, from the start of control by the power supply control device 14, in step S1, if the wind speed vx as the actual output of the anemometer 15 is equal to or higher than the wind speed vd, the process proceeds to step S2. vs or less, the process proceeds to step S3, and the power supply control device 14 activates the motor drive mode.
In step S3, the power supply control device 14 calculates the rotational force Fx, the rotational force Fs, and the difference Fa in the motor drive mode, and supplies the storage battery 17 with electric power that can supplement the rotational force corresponding to Fa. to send control signals.
Then, it returns to step S1 and step S2, and when the wind speed vx exceeds the wind speed vs, it progresses to step S4 and the electric power feeding control apparatus 14 complete|finishes a motor drive mode. When vx is equal to or less than vs, the process proceeds to step S3, where the motor drive mode is maintained and a control signal is transmitted to the storage battery 17 while performing the above calculations.

If the wind speed vx is lower than the wind speed vd in step S1, the process proceeds to step S5 to stop the motor drive mode, or if it is stopped, the stop is maintained.
This is because the rotor shaft 10 will stop if there is no power assistance from the solar power generator 7 in this state, so the power generator 12 of the wind power generator 2 will not be able to generate power unless power is constantly supplemented from the storage battery 17 . This is because the power generation efficiency of the hybrid power generation system 1 as a whole is not necessarily improved. Therefore, control is performed so that the power stored in the storage battery 17 is not lost, and is preferentially conserved until the wind force recovers and vx becomes equal to or greater than vd.
After the motor drive mode is stopped in step S5, the determination of the wind speed vx is continued from step S1 in response to the input from the anemometer 15 again.
Note that FIG. 5 does not show the contents controlled by the power supply control device 14 using the output of the anemoscope 16 . This is because the power supply control device 14 obtains the output of the anemoscope 16 to determine the orientation of the blades 3 with respect to the wind direction, or if the aforementioned yaw control device is provided, the blades 3 are oriented upwind by yaw control. This is because the orientations Fx, Fd and Fs show the steps after they can be expressed as functions or data tables of vx, vd and vs considering the orientation of the blade 3 .
In the hybrid power generation system 1 described above, electric power is stored in the storage battery only to compensate for the insufficient rotational force of the rotational force required for the static friction force fx applied to the rotor shaft 10 to exceed the maximum static friction force fs to start rotation. Since the power is supplied from 17, it is possible to reduce the amount of power to be supplied to a necessary minimum and to improve the power generation efficiency of the entire hybrid power generation system.
Further, the electric power generated by the wind power generation is not stored in the storage battery 17, and the electric power generated only by the solar power generation device 7 is used to assist the rotation, so the circuit configuration is not complicated, and operation and management are easy.
Furthermore, when the rotational force Fx is lower than the rotational force Fd, electric power cannot be generated unless electric power is continuously supplied from the storage battery 17. Therefore, the power supply control device 14 is controlled so as not to supply electric power to the generator 12, and the rotational force Fx exceeds the rotational force Fs, power can be generated without supplying power. Since the generated electric power can be operated efficiently and stably, the power generation efficiency of the entire hybrid power generation system 1 can be improved.
By obtaining Fx, Fd, and Fs in advance using the wind direction and wind speed as parameters, and by calculating the actual Fx, Fd, and Fs using the output of the anemometer 16 and the anemometer 15 by the power supply control device 14, It is possible to perform power supply control with higher accuracy, and also from this, it is possible to stably increase the power generation efficiency of the entire hybrid power generation system 1 .
By setting the installation location of the solar panel 8 on the outer wall of the tower 6, there is no need to set up the installation location of the solar panel 8 in the surrounding area, which is relatively easy compared to existing wind turbines and offshore wind turbines. It is possible to install In addition, the light receiving surface control device 20 controls the direction of the solar panel 8 according to the time of day, so that the efficiency of solar power generation can be improved.
In the present invention, a power supply control device 14 is installed inside the nacelle 5 of the wind turbine generator, etc., and a solar power generator 7 is added to the existing wind turbine generator. It is also possible to Therefore, if there is an existing wind power generator with a low operating rate, it is possible to improve power generation efficiency while suppressing costs by repairing or expanding without constructing a new one.
