Description

Wind power generation system using wind generated by moving body's running and methods for controlling the same}

The present invention relates to a wind power generation system using a driving wind of a moving object such as a car, a train, a train that runs on a track such as a road, a railroad, and a control method thereof. Specifically, the present invention can not only supply high-quality electric power and effectively utilize the driving wind generated by the moving body discontinuously traveling the track, but also by the moving bodies traveling in opposite directions on the reciprocating track. The present invention relates to a wind power generation system capable of using both forward and reverse traveling winds and minimizing turbulence effects caused by the forward and reverse traveling winds to perform efficient wind power generation, and a control method thereof.

In recent years, environmental issues have emerged as an issue worldwide, and the energy crisis such as exhaustion of fossil energy has been faced. Among the alternative energy, wind power is clean energy that is not exhausted and does not produce any environmental pollutants. It has the highest growth rate among various alternative energy, and it is relatively safe because no fire or explosion occurs in other energy generation such as nuclear power plant. After installation, the maintenance cost is low and it is attracting worldwide attention.

However, the wind power generator should be installed in a windy area, that is, at a wind speed of about 4m / s or more, and even in a windy area, the wind is not always blowing. Impossible, and if the wind direction is not constant even if the wind is blowing, there is a problem that requires a separate facility for correcting this.

Therefore, there is a need for research and development of a new type of wind power generation system that can solve the general problems of the wind power generation.

In this regard, due to the industrial development and the development of roads, bridges, underground roads, tunnels, etc., the traveling speed of vehicles driving them increases and the driving frequency increases, so that the driving of vehicles running on roads, tunnels, etc. There is a demand for wind power generation.

In general, the average traveling speed of the subway is about 25km / h, about 55 ~ 300km / h for the train, about 80km / h for the car, the air is driven by the vehicle driving at this speed The driving wind is formed while pushing in the opposite direction, and the driving wind rotates the wind turbine or the rotor, and the rotational energy is converted into electrical energy by the generator to generate electricity.

However, vehicles traveling on roads, railroads, tunnels, etc., run discontinuously, and wind turbines installed on the roads, railroads, etc. should be adopted because of small wind turbines due to their narrow installation space and safety issues. Wind power generation using the driving wind of the small amount of discontinuous power is produced, there is a limit of low utilization. In addition, the wind power generator using the driving wind of the vehicle has a problem in that the turbulence effect caused by the driving wind of the vehicles traveling in opposite directions when the track on which the vehicle runs is a reciprocating track reduces the efficiency of the wind power generation.

There are some prior art related to wind power generation using the running wind of the vehicle, but it is not presenting a feasible means to solve the problems of wind power generation using the driving wind of the vehicle, or the presented means sufficiently solves the problems. It is not solved or is causing other problems.

It is difficult or impossible to realize the technical means in terms of cost or process, such as the construction of an exhaust outlet, and still does not solve the above problems of wind power generation using the driving wind of discontinuously traveling vehicles.

Therefore, it is possible to supply high-quality electric power by using the driving wind by the discontinuously running vehicle and to effectively utilize it, and to minimize the turbulence effect caused by the vehicles traveling in opposite directions on the reciprocating track, thereby effectively generating wind power.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. Like numbers refer to like elements throughout.

1 attached to the present specification shows an example of a track that can use the wind power generation system according to the present invention. Here, the "track" refers to a line that travels by train, tram, or car. Specifically, FIG. 1A illustrates a reciprocating road in which cars, motorcycles, and the like travel in opposite directions with different lanes. Preferably for wind power, the road may be a highway. Wind generators 10 may be installed on each outside of the reciprocating road. In addition, in the reciprocating road, the wind turbine 10 may be installed at a center line that divides lanes having different driving directions, and in this case, the wind turbine 10 may be integrally installed with the central separation structure.

FIG. 1B illustrates a reciprocating road in which vehicles, motorcycles, and the like travel in opposite directions with different lanes in a ground or underground tunnel structure. Since the upper part of the tunnel structure has a low driving wind speed by securing a space according to installation of a different height and an exhaust port for each vehicle, it is preferable to install the wind power generator 10 on the inner surface of the tunnel structure having a relatively high driving wind speed.

1C and 1D illustrate a reciprocating railway in which trains, trains, and the like travel in opposite directions with different lanes in a ground or underground tunnel structure. It is preferable to install the wind turbine 10 on the inner surface of the tunnel structure for the same reason as the reciprocating railway in the tunnel structure. In particular, in FIG. 1C, the wind power generator 10 may be installed in the lower space of the platform of the station where the train or the train stops.

2 is a configuration chart of a wind power generation system according to an embodiment of the present invention. As shown in FIG. 2, the wind power generation system according to the present invention may include one or more wind turbines 10 on each outside of the track, and the wind turbines 10 may be arranged at regular intervals along the track. have.

Power generated by the wind turbine 10 by the driving wind of a vehicle traveling on a track is stored in the energy storage device 30 electrically connected to the wind turbine 10, and then stored in the energy storage device 30. Power is supplied to the electrical installation 90 through the main switch 50 and the sub switch 80 electrically connected thereto.

On the other hand, the alternating current power produced by the wind turbine 10 is converted into direct current power through a converter 20 that can be additionally installed between the wind turbine 10 and the energy storage device 30 to store the energy DC power stored in the device 30 and also stored in the energy storage device 30 may be converted into AC power by an inverter (not shown) which may be further installed and then transferred to the electrical installation 90. Can be supplied.

In addition, the wind power generation system according to the present invention may further include a power saver 40 between the energy storage device 30 and the main switch 50.

The power protector 40 protects the electrical installation 90 from an instantaneous overcurrent due to the opening and closing of the main switch 50 or lightning strike, and preferably, a surge protector may be used. In addition, the electrical installation 90 may be a street light, tunnel lighting, a rapid turn light, a road sign lighting, an electronic sign, and the like.

The wind power generation system according to the present invention may include an optical sensor (not shown) for measuring the amount of light around a track on which a moving object such as a vehicle travels. The optical sensor measures an amount of light around the line and transmits an electrical signal corresponding to the optical signal to the controller 90. Although there is no particular limitation on the light sensor, an illumination sensor (CDS sensor) having a simple circuit and a low cost is preferable because it is sufficient to determine the degree of "bright / dark" rather than measuring the exact amount of light.

As shown in FIG. 3, the controller 70 receives an electrical signal corresponding to the amount of light measured by the light sensor to determine whether power is supplied to a lighting device such as a street lamp, a road sign lighting, and the like that are the electrical installation 90. And control the opening and closing of the main switch 50 accordingly.

That is, when the amount of light measured by the optical sensor indicates that the lighting of the electrical equipment 90 such as a street lamp on the track is not necessary for driving of the vehicle, the controller 70 controls the main switch to control the electrical equipment 90. It cuts off the power supply to the energy storage device 30 to charge the power. On the other hand, when the amount of light measured by the optical sensor indicates that the electric equipment 90 on the track needs to be turned on in order to drive the vehicle, the controller 70 controls the main switch to control the respective switches through the sub-switch 80. Supply electric power to the electrical installation (90).

In addition, the wind power generation system according to the present invention may include a moving sensor 60 that can detect the speed of the moving object traveling on the track. The moving object sensor 60 may generally use a speed sensor using a Doppler effect such as ultrasonic waves, lasers, microwaves, etc., and there is no particular limitation as long as it can measure a vehicle traveling speed in a range of 400 km / h or less. In addition, the movable body sensor 60 may be provided with a plurality of movable body sensors 60 at regular intervals along the track. The electrical signal corresponding to the speed of the moving object measured by the moving object sensor 60 is transmitted to the controller 70 electrically connected thereto.

The controller 70 receives an electrical signal corresponding to the speed of the moving object measured by the moving object sensor 60 to predict the position of the moving object on the track as shown in FIG. 3 and based on the plurality of sub-switches ( 80 is selectively supplied to only the electrical equipment 90 of a specific section.

That is, the control unit 70 should be secured to predict the position of the moving object over time on the track based on the speed of the moving object measured by the moving object sensor 60 and to allow the driver who drives the moving object to perform safe driving. The sub-switch 80 is selectively controlled to supply electric power only to the electrical installation 90 such as a street lamp, a tunnel light, a road sign lighting, and the like installed on a specific section on the track corresponding to the viewing range. The faster the speed of the moving body, the farther the field of view for the safe driving of the driver driving the moving body should be secured to a farther distance, so that the length of the specific section on the track also increases in proportion to the speed of the moving body. Preferably, the specific section may be longer than the braking distance of the moving object. For example, when the speed of the moving object is 100km / h, the specific section may be about 40m. Such a control system can reduce the power consumption caused by unnecessary lighting of the electrical installation 90, thereby effectively utilizing the limited power produced by the wind power generation system, and is particularly effective on a low-frequency track of a traveling vehicle. .

In addition, the wind power generation system according to the present invention is an auxiliary power supply 100 for supplying auxiliary power to the energy storage device 30 and the auxiliary switch 110 located between the energy storage device 30 and the auxiliary power supply (100). ) May be further included. The controller 70 calculates the driving wind power and the amount of power generated based on the speed of the moving body detected by the moving object sensor 60 and the shape of the moving body additionally detected, that is, the height and length of the moving body affecting the driving wind power. And a power monitoring device (not shown) for monitoring the amount of remaining power stored in the energy storage device 30 in real time.

By controlling the main switch 50 and the auxiliary switch 110 according to the amount of power secured by the power monitoring device, the surplus power is supplied from the energy storage device 30 to another power system through a grid connection, The auxiliary power is supplied from the auxiliary power source 100 to the energy storage device 30.

As a result, even when the amount of power charged in the energy storage device 30 is insufficient, the electric equipment 90 on the track can be continuously operated to ensure safe driving of the vehicle and at the same time, the surplus power can be used in another power system. .

4 is a control flowchart of a wind power generation system according to an embodiment of the present invention.

The wind power generation system according to the present invention measures the amount of light around the line by the optical sensor, and if the lighting of the electrical equipment 90 around the line is determined according to the measured light amount, the control unit 70 switches the main switch. The controller 50 controls power 50 to supply power from the energy storage device 30, and detects the speed of the moving object by the moving object sensor 60. The control unit 70 controls the respective sub-switches 80 based on the moving object sensor 60. By controlling the power supply of the control unit 70, while selectively supplying power only to the electrical equipment 90 installed in a specific section corresponding to the viewing range to be secured so that the driver driving the mobile device can safely drive Is calculated based on the speed and shape of the moving object detected by the moving object sensor 60 (height, length, etc.) and the energy storage device 3 By monitoring the amount of remaining power charged in the real time in real time and controlling the main switch 50 and the auxiliary switch 110 based on this, the surplus power is supplied to the other power system from the energy storage device 30 or the auxiliary power It is controlled by supplying the energy from the auxiliary power source 100 to the energy storage device 30.

Figure 5 shows an example of a wind generator constituting a wind power generation system according to the present invention. The wind generator 10 includes a rotary shaft 11 and a rotary blade 12 which is fixed to the rotary shaft 11 and extends in an outward direction of the rotary shaft radius to rotate by a traveling wind. As the rotary blade 12 rotates due to the running wind, the rotary shaft 11 wound around the coil rotates together in the magnetic field, thereby generating induced electromotive force due to electromagnetic induction.

Wind turbines are classified into vertical shaft wind turbines and horizontal shaft wind turbines according to their structure. That is, the axis of rotation is formed vertically with one surface of the ground or the structure on which the wind turbine is installed, that is, the axis of rotation is formed vertically with the wind direction is a vertical axis wind power generator, on the contrary, the axis of rotation is formed horizontally with one surface of the ground or structure It is a horizontal axis wind power generator.

The wind turbines shown in FIG. 5 are all vertical axis wind turbines. Specifically, FIG. 5A is a darrieus type wind power generator, and in theory, if the wind speed is constant, the wind turbine can produce an efficiency similar to that of a horizontal axis wind power generator, and it is economical because it can reduce the material cost of expensive rotary blades when manufacturing the wind power generator. . In addition, Figure 5b is a savonious (savonious) wind power generator, it can be said to be the simplest type of vertical axis wind power generator, the power production efficiency is relatively low, but has the advantage of low price. And, Figure 5c is a wind power generator named eddy (eddy), there is an advantage that can minimize the effect of the turbulent effect without causing a loud noise. Finally, Figure 5d is a combined wind turbine of Darius type and Savonius type.

The vertical axis wind power generator can be manufactured in a small size so that it can be installed in a narrow space on the outside of a road, and can generate power regardless of the change in driving wind direction caused by vehicles traveling in opposite directions on a reciprocating road, and minimizes the turbulence effect. Since there is an advantage that the design of the structure can be possible, it is preferable that the wind power generation system according to the present invention adopt the vertical axis wind power generator.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims. .
