Abstract

(57) [Abstract] [Purpose] A hybrid (composite) power generator using wind power and solar power is installed on the steel tower of the power transmission line to supply low-cost electric power from infinite natural energy. [Structure] A horizontal-blade wind turbine generator is installed on the top of the steel tower at a location suitable for the wind conditions, such as the ridge of a mountainous area, where the power transmission line is located (where wind blows at a wind speed of 5 to 20 m / s). At the same time, a solar power generation panel (solar cell module) is installed on the upper inclined surface of the arm to combine and store electricity, and the combined electric power (wind power and solar power) generated at each steel tower is installed on the overhead ground wire. Connect the cables in parallel to supply the power to the nearest load or substation.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention installs both wind power generation and solar power generation devices on the support of an existing transmission line, combines and accumulates the power generated by this, and the combined power is installed in the ground. It relates to a hybrid power generation system that uses lines to connect and transport.

[0002]

[Prior art]

 For wind power generation equipment, a wind turbine (horizontal axis type), which generally has a power generation function, and an independent support (steel pipe, steel pillar or tower) are used to mount the generator at a high place. It is erected in a place (where the wind is constantly blowing) and close to the place of demand, and the generated power is supplied to the nearest substation through buried cables. For low-voltage, direct-current photovoltaic power generation equipment, generally, a solar cell panel is installed on the roof of a building or on a flat pedestal according to the demand, and the generated power is converted according to the working load ( In addition to voltage and frequency, it is directly supplied to the load by an insulated cable. In addition, since the power generation efficiency of wind power and solar power generation is due to irregular weather conditions and intermittent energy, in general, the equipment is usually small-scale and independent type. There is no power generation system that aggregates the equipment, combines both large-scaled equipment, and grid-combines the combined power with a commercial power grid, and also installs both wind and solar power generation equipment on the support of the existing transmission line. There is no example in which a large number of electric power lines are installed and used to supply the combined and accumulated electric power through the transmission line.

[0003]

[Problems to be solved by the device]

 Regarding the former among the conventional techniques mentioned in the previous section, generally speaking, the rotor blades (hereinafter referred to as rotors) of wind turbine power generation equipment are of the same horizontal axis type as the fan, and the rotating surface of the rotor is vertical, and the rotating shaft also depends on the wind direction. Because of the horizontally rotating operation mechanism, this mechanism could not be applied on the support of the transmission line where the wire was stretched.

Regarding the latter, there was no outdoor storage battery (non-inspection) suitable for accumulating the electric power generated by the solar cell in the mountainous remote area, and the generated electric power was effectively remote from the small electric power (low voltage). There was a problem that it was difficult to transport to the demand point.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to use a steel tower of a power transmission line as a support and utilize the top space thereof. A vertical axis wind turbine generator with horizontal rotors was installed, a solar panel was installed using the upper slope of each arm, and both wind and solar power generators were installed using the main landing. It will combine and store the generated power, and will also connect the power generators of each tower to increase the output due to the assembly and always deliver stable power remotely.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the wind turbine generator of the present invention adopts a vertical axis type wind turbine in which the rotor or the cup rotates horizontally, and installs it in the space at the top of the tower with excellent wind conditions. This enables wind turbine power generation day and night regardless of wind direction. (The conventional wind direction tracking mechanism is unnecessary)

[0007] Further, by installing a solar panel on the upper slope of the steel tower armband with good solar radiation efficiency, solar power generation during the day becomes possible. (The panel is installed horizontally and the effect of wind pressure is small)

[0008] In order to combine and interchange the electric power generated by wind power and sunlight in each steel tower, a power storage / conversion device (battery, inverter, etc.) is installed in each main tower at the main landing, and the generated power is stored. In order to perform conversion and supply to remote areas due to an increase in combined electric energy, each tower will be interconnected by a connecting line attached to an overhead ground line.

[0009]

[Action]

 The rotor of the vertical axis type wind turbine that rotates horizontally is not a lift type but a drag type as with the Robinson anemometer, and its structure consists of four "scattered lotus" type cups arranged in a cross shape as shown in Fig. 2. , It is pushed by the wind and rotates in one direction. The material of the air cup is lightweight and tough FRP, etc., and the vertical axis of rotation is set so that the rotor can be installed at a position higher than 1 m above the tower top. The connecting portion of the rotating shaft of the wind turbine and the generator has a structure in which both rotating shafts are separated by the levitation force when the wind speed is 20 m or more.

A wind turbine generator (AC or DC) is installed at the landing of the first section of the main body, and the rotor and the generator installed at the top of the tower are connected by a vertical rotating shaft, and the inclination of the wind turbine at the top of the tower is fixed. Hold the rotating shaft at the top of the tower to prevent it.

The solar panel is attached by using the parts of the upper inclined surface (suspension structure plane) of each arm (upper, middle, lower, 2 lines, 6 places), and the lead wire of FIG. Connect in parallel to the controller installed at the landing of the 3rd section of the main body.

An inverter (DC to AC conversion) and a converter or a charger (AC to DC conversion) are installed at the landing of the second section of the main body, and a battery for storage (outdoor, non-inspection type) is installed at the landing of the third section. As shown in Fig. 4, connect each with an insulated cable and connect the generator and the inverter, the converter, and the controller and the battery with the insulated cable.

[0013] In order to enable long-distance transportation due to the composite increase of the combined electric power generated in each tower, a connecting wire is separately attached (wound in a spiral shape) using the overhead ground wire installed between the towers. Then, this connecting line interconnects the inverters of each tower.

[0018]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

Since the towers that run on the twill line in the mountainous area have high altitudes and have location conditions that excel in wind conditions, a wind turbine generator is installed at the top of each successive tower. Wind (natural) energy can be effectively used by connecting (aggregating).

Generally, the structure of the support of the power transmission line (steel tower, etc.) is simple and high, and the standing condition with good solar radiation efficiency is provided, so solar power generators are installed on the upper slopes of the arms of each successive steel tower. However, by interconnecting (aggregating) this, sunlight (natural) energy can be effectively used.

Increased output of combined power generated by connecting and interconnecting both wind power and solar power generators installed using the space on each tower as described above using existing cabling lines At the same time, it is possible to reduce the cost of power transportation equipment.

Since existing supports such as steel towers can be used, land costs are unnecessary and construction costs are low.

Since the energy resources are clean and unlimited, the long-term power generation cost is low.

It has a wide range of uses such as aviation obstruction lights, power supply for on-board work, and power supply to electric facilities in remote areas, and has a high general-purpose value.
