Description

{TWO-STAGE OUTPUT GENERATOR}

The present invention relates to a two-stage output type generator, and more particularly, to a two-stage output type generator for converting a rotational force applied from the outside into electric energy.

In general, a generator is configured to generate a designed capacity using a power generation source. Therefore, when the generator is powered by a given power source, it is necessary to use a proper torque or other power generation driving force. If the power generation driving force is not below the standard due to an external factor, the power generation is stopped or the power generation efficiency is lowered. Particularly, such a problem can be remarkably exhibited in the renewable energy field where power generation driving force is easily changed due to external environment factors such as hydroelectric power, wind power, and tidal power. Therefore, in many cases, a method of responding to changes in external environmental factors and improving power generation efficiency through the control of the number of revolutions or torque is adopted. In some cases, a method of allowing a plurality of generators having different design capacities to operate irregularly .

However, in the case of the former, there is a limitation in improvement of the power generation efficiency because it follows the design reference value indirectly through the number of revolutions or torque control within the specification of the limited generator. Therefore, in the latter case, It is not a viable alternative because of rising costs. Therefore, along with the rapid growth of the renewable energy field, there is a demand for a power generation means capable of flexibly coping with varying external factors and capable of generating electricity in response to a power source of a larger capacity.

3, the two-stage output type generator G according to the present embodiment may further include a gear assembly 30. As shown in FIG. The gear assembly 30 transmits the rotational driving force applied to the input shaft R to the first power generation module 10 or the second power generation module 20 to generate the power of the first power generation module 10 or the second power generation module 20 Thereby enabling selective driving.

6 is an enlarged perspective view showing the gear assembly 30 shown in Fig.

6, the gear assembly 30 includes a sun gear 31 provided on the first rotor shaft 12a, a plurality of planetary gears 32 engaged with the sun gear 31, and a carrier 33 Lt; / RTI >

The sun gear 31 can be rotated together with the first rotor shaft 12a. Therefore, while the rotational driving force is applied to the input shaft R, the sun gear 31 can be driven to rotate continuously. The plurality of planetary gears 32 are engaged with the sun gear 31 and can be revolved around the outer periphery of the sun gear 31 or rotated in place. The plurality of planetary gears 32 can be engaged with the ring gear 12d by inserting into the ring gear 12d on the inner circumferential surface of the first rotor bracket 12b. Therefore, when the first power generation module 10 is selectively driven, the rotational driving force applied through the input shaft R is transmitted to the first rotor shaft 12a, the sun gear 31, the plurality of planetary gears 32 and the ring gear 12d To the first rotor bracket 12b and the first winding block 12c.

The carrier 33 is coupled to the plurality of planetary gears 32 to provide rotation shafts to the planetary gears 32 for rotation and to transmit rotational driving force to the second power generation modules 20 at the rear And a carrier shaft 33a.

The gear assembly 30 selectively drives the first power generation module 10 or the second power generation module 20 through the revolution or rotation of the planetary gear 32. That is, the gear assembly 30 rotates or rotates the planetary gear 32 in accordance with the operating conditions and the electrical load applied to the power generation modules 10 and 20, whereby the first rotor assembly 12 or The second rotor assembly 22 to be described later is selectively rotated to generate electricity in the first power generation module 10 or the second power generation module 20. Therefore, the two-stage output type generator G according to the present embodiment selectively drives the first power generation module 10 or the second power generation module 20 according to the operating conditions through the gear assembly 30 while minimizing the structural complexity So that the power generation efficiency can be improved.

In addition, since the gear assembly 30 includes a planetary gear structure capable of increasing and decreasing speed, there is no need for a separate accelerator and decelerator outside the apparatus. Therefore, the two-stage output type generator G according to the present embodiment is advantageous in that the acceleration and deceleration means are integrated inside the device, and the entire system and the configuration of the external device can be simplified.

7 is a perspective view showing a state in which the outer housing is removed from the two-stage output type generator G shown in Fig. 8 is a side view of the two-stage output type generator G shown in Fig. 9 is an enlarged perspective view of the second power generation module 20 shown in FIG. It is noted that the first power generation module 10 is omitted in FIG. 8 for convenience of explanation.

Referring to FIGS. 7 to 9, the two-stage output type generator G according to the present embodiment may include a second power generation module 20. The second power generation module 20 may be configured as one independent power generation unit that is different from the first power generation module 10 and may be configured such that the first power generation module 10 and the power generation capacity are different from each other have. This is to improve the power generation efficiency by selectively driving the first power generation module 10 or the second power generation module 20 according to operating conditions.

The second power generation module 20 may include a second rotor assembly 22 and a second stator assembly 21. The second stator assembly 21 includes a second stator core 21a and a second stator coil 21b and may be formed in a hollow cylindrical shape and may be fixed to a housing or the like so as to be rotationally restrained with respect to the axial direction.

The second rotor assembly 22 may include a second rotor shaft 22a, a second rotor bracket 22b, and a plurality of second winding blocks 22c. At this time, the second rotor shaft 22a is axially coupled with the carrier shaft 33a through the coupler C or the like and can receive the rotational driving force from the carrier shaft 33a. The second rotor bracket 22b may be coupled to the second rotor shaft 22a and rotated together with the second rotor shaft 22a and the plurality of second winding blocks 22c may be coupled to the second rotor bracket 22b In the circumferential direction. A plurality of second slot grooves 22d for coupling the second winding block 22c may be provided on the outer circumferential surface of the second rotor bracket 22b as necessary.

The second power generation module 20 is configured such that the rotational driving force is transmitted to the second rotor shaft 22a by the carrier shaft 33a and the second rotor assembly 22 is rotated about the second stator assembly 21 The power generation is performed while being rotationally driven.

Fig. 10 is a conceptual diagram for explaining the operation of the two-stage output type generator G shown in Figs. 1 to 9. Fig. 10 (a) shows the operation when the first power generation module 10 is driven, and FIG. 10 (b) conceptually shows the operation when the second power generation module 20 is driven Leave.

In the meantime, as described above, the first power generation module 10 or the second power generation module 20 is selectively driven in accordance with each operating condition of the two-stage output type generator G according to the present embodiment. Hereinafter, the operating condition in which the first power generation module 10 is driven is referred to as a first operating condition, and the operating condition in which the second power generation module 20 is driven is referred to as a second operating condition. At this time, the selective drive according to each operating condition can be set in consideration of power generation efficiency under the corresponding operating condition of each power generation module 10, 20, and the like.

First, the operation when the first power generation module 10 is driven will be described with reference to FIG. 10 (a) and FIG. 7 described above. The first rotor shaft 12a and the sun gear 31 coupled to the first rotor shaft 12a are rotated. As the sun gear 31 rotates, a plurality of planetary gears 32 meshed with the sun gear 31 are driven. At this time, the respective planetary gears 32 can be rotated in a state in which idle rotation is restricted.

The operation of the planetary gear 32 as described above can be realized by applying a high power generation load to the second power generation module 20 connected to the carrier shaft 33a to generate a rotational resistance in the second rotor shaft 22a. That is, if a power generation load is electrically applied to the second power generation module 20, rotational resistance is generated (i.e., electrically braked) in the second rotor assembly 22 and the second rotor shaft 22a, The axial rotation of the carrier shaft 33a and the carrier 33 connected to the second rotor shaft 22a is restrained. Therefore, each of the planet gears 32 can be rotated only by the carrier 33 with the idle motion restricted.

On the other hand, when the respective planetary gears 32 are rotated, the first rotor bracket 12b engaged with the planetary gear 32 is driven to rotate about the sun gear 31 through the ring gear 12d on the inner peripheral surface, The first rotor assembly 12 is rotated with respect to the first stator assembly 11 in accordance with the rotation of the first rotor bracket 12b and power generation is performed in the first power generation module 10.

Next, the operation when the second power generation module 20 is driven will be described with reference to FIG. 10 (b) and FIG. 7 described above. The rotational driving force of the input shaft R is transmitted to the first rotor shaft 12a and the sun gear 31 when the operating condition is changed to the second operating condition different from the first operating condition. This is the same as the operation under the above-described first operating condition.

That is, in the two-stage output type generator G according to the present embodiment, an external rotational driving force is continuously applied to the input shaft R. The first rotor shaft 12a and the sun gear 31 are connected to the first power generation It can be continuously rotated during operation regardless of the selective drive of the module 10 or the second power generation module 20. [ Therefore, the two-stage output type generator G according to the present embodiment is not required to stop the operation of the apparatus or to change the connection relationship for switching to the power generation modules 10 and 20, The switching to the power generation modules 10 and 20 and the selective driving can be performed.

Meanwhile, when the second power generation module 20 is driven, as the sun gear 31 rotates, the plurality of planetary gears 32 can be idly rotated. At this time, the revolution of the planetary gear 32 can be induced by applying a high power generation load to the first power generation module 10 to generate a rotational resistance in the first rotor bracket 12b. That is, in this operation example, in contrast to the above-described first operating condition, the electric power generation load may be applied to the first power generation module 10, thereby causing a rotational resistance to be generated in the first rotor bracket 12b And the planetary gears 32 revolve about the sun gear 31 with the ring gear 12d being restricted in rotation. As the planetary gear 32 revolves, the carrier 33 and the carrier shaft 33a are rotationally driven about the axial direction of the input shaft R. The rotation of the carrier shaft 33a is transmitted to the second rotor shaft 22a to the second power generation module 20 so that the second power generation module 20 generates power.

As described above, the two-stage power generator (G) according to the present embodiment is provided with the first and second power generation modules (10, 20) having different power generation capacities and rated speeds and are suitable for power generation efficiency The power generation modules 10 and 20 are selected and driven. Particularly, the switching between the first and second power generation modules 10 and 20 is performed by applying an electrical load to the first power generation module 10 or the second power generation module 20 in a state in which the rotational driving force is continuously applied to the input shaft R And can be switched during operation without stopping the operation of the apparatus. In addition, although the plurality of power generation modules 10 and 20 and the switching means (i.e., the gear assembly 30) are integrated to improve the power generation efficiency, in order to minimize the structural complexity, , Durability, maintenance, and parts replacement.

On the other hand, in the case of this embodiment, the case where the switching between the first and second power generation modules 10 and 20 or the selective driving is performed by the electrical braking through the power generation load is exemplified. However, It can be said that.

In addition, the two-stage output type generator G according to the present embodiment may further include a control unit. The control unit can control the switching between the first and second power generation modules 10 and 20 and the selective driving according to each operating condition set by the user.

Fig. 11 is a block diagram showing a schematic control process of the two-stage output type generator G shown in Figs. 1 to 9. Fig.

Referring to FIG. 11, when the rotational driving force is applied to the input shaft R, the controller may check the generator state whether the load control power is equal to or greater than a reference value. As a result of the check, if the load control electric power is lower than the reference value, the controller can receive the load control electric power through the uninterruptible power supply (UPS).

If the load control power is equal to or greater than the reference value, the control unit may analyze at least one of the rotational speed, the rotational speed, and the rotational torque of the input shaft R to match the predetermined operating condition. At this time, the respective operating conditions can be set in consideration of the power generation capacity, rated speed, torque, etc. of the first and second power generation modules 10 and 20, and the first operating condition in which the first power generation module 10 is driven, 2 power generation module 20 is driven.

When the first operation condition is matched (the first power generation requirement is satisfied), the control unit applies a power generation load to the second power generation module 20 through the load control power and electrically brakes the second power generation module 20. [ In this case, the rotation of the carrier 33 is restricted so that the rotational driving force applied to the input shaft R rotates the respective planetary gears 32, and correspondingly, the first rotor assembly 12 is driven to rotate 1 power generation module 10 (Fig. 7 (a)). In addition, the control unit analyzes the power generation amount and transmits the generated power to the UPS or the power grid (transmission tower).

On the other hand, when the rotational speed of the input shaft R is analyzed to find that it matches the second operating condition (satisfying the second-stage power generation requirement), the control unit applies a power generation load to the first power generation module 10 via the load control power Thereby electrically braking the first power generation module 10. The rotation of the first rotor bracket 12b can be restricted and the rotational driving force of the input shaft R is transmitted to the carrier shaft 33a through the idle motion of the respective planetary gears 32 b)). Accordingly, the second rotor shaft 22a and the second rotor assembly 22 are rotationally driven to generate electric power from the second power generation module 20.

As described above, the two-stage output type generator G according to the embodiments of the present invention includes the first and second power generation modules 10 and 20 having different power generation capacities and the like, So that the module 10 or the second power generation module 20 can be appropriately selectively driven. Therefore, the two-stage output type generator G according to the embodiments of the present invention can cope more flexibly with operating conditions and external environment changes, and can contribute to enhancement of the overall power generation efficiency of the system. In addition, the drive switching between the power generation modules 10 and 20 can be performed easily through the electric load control, and it is advantageous in that switching between the power generation modules 10 and 20 in the operating state and switching of continuous driving are very easy.

The two-stage output type generator G according to the embodiments of the present invention has a structure in which the first and second power generation modules 10 and 20 of mutually separated form are sequentially coupled in the axial direction of the input shaft R, And the switching between the first and second power generation modules 10 and 20 and the selective driving can be accomplished through the gear assembly 30 disposed inside the apparatus rather than a complicated link structure or control mechanism, The efficiency can be maximized while the structural complexity can be minimized.

Furthermore, the two-stage output type generator G according to the embodiments of the present invention can omit the additional acceleration and deceleration means by the gear assembly 30 including the planetary gear structure, and the rotor brackets 12b, 22b are modularly shaped and the winding blocks 12c, 22c are assembled and assembled. It is also easy to change the power generation capacity or the like by replacing the winding blocks 12c, 22c.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, many modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
