As shown in FIG. 1, a wind power generator (a tower-shaped building) 1 includes a cylindrical tower 3 installed on a foundation 2 provided on the ground or the ocean, and an axial center of the tower 3 at the top 3 a of the tower 3. (Axis) A nacelle (wind turbine main body) 4 supported so as to be turnable around the axis C and a rotor head 5 supported on the front side of the nacelle 4 are provided. The nacelle 4 accommodates a speed increaser 6 and a generator (upper electrical equipment) 7. The rotor head 5 has a plurality of wind turbine blades 9 on the outer periphery of the hub 8. A main shaft 5 a extending from the hub 8 into the nacelle 4 is connected to the speed increaser 6, and an output shaft 6 a extending from the speed increaser 6 is connected to the generator 7.

ロータヘッド５の回転動力は、増速機６を介して発電機７に入力されて、この発電機７に電力を発生させる。発電機７が発生した電力は、タワー３の下部内で基礎２上に設置された発電制御盤（下段電気設備）１１に送られる。タワー３内には、発電機７から発電制御盤１１に向けて延びる高圧ケーブル（送電ケーブル）１２が挿通される。タワー３の上部内（あるいはナセル４内）には、マスダンパー型の制振装置１３が設置される。   The rotational power of the rotor head 5 is input to the generator 7 via the speed increaser 6 and causes the generator 7 to generate electric power. The electric power generated by the generator 7 is sent to a power generation control panel (lower electrical equipment) 11 installed on the foundation 2 in the lower part of the tower 3. A high voltage cable (power transmission cable) 12 extending from the generator 7 toward the power generation control panel 11 is inserted into the tower 3. A mass damper type damping device 13 is installed in the upper part of the tower 3 (or in the nacelle 4).

以下、図２〜４を参照して制振装置１３について説明する。なお、図中矢印ＵＰが上方、矢印ＦＲが前方、矢印ＬＨが左方を示すものとする。
制振装置１３は、タワー３の頂部内フレーム３ｂの下面側に固定される円盤状の上段支持板１４と、上段支持板１４の下面側に固定される前後一対のＸ軸直動レール１５と、前後Ｘ軸直動レール１５にそれぞれ左右移動可能に支持される左右一対のＸ軸移動脚１６と、上段支持板１４の下面側に固定的に支持されるＸ軸サーボモータ１７と、Ｘ軸サーボモータ１７によりカップリング１７ａを介して駆動されるＸ軸ボールネジ機構１８と、Ｘ軸ボールネジ機構１８の可動子（ボールナット１８ａ）が固定されると共に各Ｘ軸移動脚１６がそれぞれ固定される円盤状の中段支持板２１とを有する。 Hereinafter, the vibration damping device 13 will be described with reference to FIGS. In the figure, an arrow UP indicates an upward direction, an arrow FR indicates a front direction, and an arrow LH indicates a left direction.
The vibration damping device 13 includes a disk-shaped upper support plate 14 fixed to the lower surface side of the top inner frame 3 b of the tower 3, and a pair of front and rear X-axis linear motion rails 15 fixed to the lower surface side of the upper support plate 14. A pair of left and right X-axis moving legs 16 supported by the front and rear X-axis linear motion rails 15 so as to be movable left and right, an X-axis servomotor 17 fixedly supported on the lower surface side of the upper support plate 14, and an X-axis An X-axis ball screw mechanism 18 driven by a servo motor 17 through a coupling 17a, and a disk on which a movable element (ball nut 18a) of the X-axis ball screw mechanism 18 is fixed and each X-axis moving leg 16 is fixed. And a middle support plate 21 having a shape.

また、制振装置１３は、中段支持板２１の下面側に固定される左右一対のＹ軸直動レール２２と、左右Ｙ軸直動レール２２にそれぞれ前後移動可能に支持される前後一対のＹ軸移動脚２３と、中段支持板２１の下面側に固定的に支持されるＹ軸サーボモータ２４と、Ｙ軸サーボモータ２４によりカップリング２４ａを介して駆動されるＹ軸ボールネジ機構２５と、Ｙ軸ボールネジ機構２５の可動子（ボールナット２５ａ）が固定されると共に各Ｙ軸直動レール２２がそれぞれ固定される円盤状の下段支持板２６とを有する。   Further, the vibration damping device 13 includes a pair of left and right Y-axis linear motion rails 22 fixed to the lower surface side of the middle support plate 21 and a pair of front and rear Y supported by the left and right Y-axis linear motion rails 22 so as to be movable forward and backward. An axis moving leg 23, a Y axis servo motor 24 fixedly supported on the lower surface side of the middle support plate 21, a Y axis ball screw mechanism 25 driven by the Y axis servo motor 24 via a coupling 24a, A movable member (ball nut 25a) of the shaft ball screw mechanism 25 is fixed, and a disk-like lower support plate 26 to which the Y-axis linear motion rails 22 are fixed.

下段支持板２６の下面側には、制振装置１３のマス（質量体）たる円盤状のウェイト２７が固定支持される。このウェイト２７をＹ軸サーボモータ２４により前後に変位させると共にＸ軸サーボモータ１７により左右に変位させることで、制振装置１３のマス（質量体）の移動反力により風力発電装置１の振動を低減させる。すなわち、制振装置１３は、アクチュエータ（各サーボモータ１７，２４）から付与された外力によってマスに制振に適した動きをさせるアクティブ制振を行う。   On the lower surface side of the lower support plate 26, a disk-shaped weight 27, which is a mass of the vibration damping device 13, is fixedly supported. The weight 27 is displaced back and forth by the Y-axis servo motor 24 and left and right by the X-axis servo motor 17 so that the vibration of the wind turbine generator 1 is vibrated by the movement reaction force of the mass (mass body) of the vibration damping device 13. Reduce. That is, the vibration damping device 13 performs active vibration damping that causes the mass to make a motion suitable for vibration damping by an external force applied from the actuator (the servo motors 17 and 24).

なお、図中符号２８は上段支持板１４の下面側の左右端部で前後一対に設けられたＸ軸ストッパを、符号２８ａは上段支持板１４の下面側の左右で各Ｘ軸ストッパ２８の左右方向内方に離間して設けられたＸ軸ストッパ片をそれぞれ示す。また、図中符号２９は中段支持板２１の下面側の前後端部で左右一対に設けられたＹ軸ストッパを、符号２９ａは中段支持板２１の下面側の前後で各Ｙ軸ストッパ２９の前後方向内方に離間して設けられたＹ軸ストッパ片をそれぞれ示す。   In the figure, reference numeral 28 denotes a pair of front and rear X-axis stoppers at the left and right end portions on the lower surface side of the upper support plate 14, and reference numeral 28a denotes a left and right side of each X-axis stopper 28 on the left and right sides of the upper support plate 14. X-axis stopper pieces that are spaced apart inward in the direction are shown. Further, in the figure, reference numeral 29 denotes a pair of left and right Y-axis stoppers at the front and rear end portions on the lower surface side of the middle stage support plate 21, and reference numeral 29 a denotes the front and rear of each Y axis stopper 29 on the front and rear side of the lower stage side of the middle stage support plate 21. Y-axis stopper pieces that are spaced apart inward in the direction are shown.

ここで、ウェイト２７及び各支持板１４，２１，２６の上下方向から見た中央部分には、上下方向から見て矩形状をなす開口３１，３２，３３，３４がそれぞれ形成される。各開口３１，３２，３３，３４は、上下方向から見て各直動レール１５，２２に囲まれた範囲（前後方向では前後Ｘ軸直動レール１５に挟まれ、かつ左右方向では左右Ｙ軸直動レール２２に挟まれた範囲）に形成される。これら各開口３１，３２，３３，３４により、制振装置１３の中央部分には、前記高圧ケーブル１２を上下に挿通可能なケーブル挿通路が形成される。なお、頂部内フレーム３ｂにも上下方向から見て前記各開口３１，３２，３３，３４と重なる範囲に開口が形成されている。   Here, openings 31, 32, 33, and 34 each having a rectangular shape as viewed from the top and bottom are formed at the center portions of the weight 27 and the support plates 14, 21, and 26 as viewed from the top and bottom. Each opening 31, 32, 33, 34 is a range surrounded by the linear motion rails 15, 22 when viewed in the vertical direction (the front / rear direction is sandwiched between the front / rear X-axis linear motion rails 15 and the left / right direction is the left / right Y axis) A range sandwiched between the linear motion rails 22). By these openings 31, 32, 33, 34, a cable insertion passage through which the high-voltage cable 12 can be inserted vertically is formed in the central portion of the vibration damping device 13. Note that the top inner frame 3b is also formed with openings in a range overlapping the openings 31, 32, 33, and 34 when viewed in the vertical direction.

図５を参照し、ウェイト２７の開口３１（及び下段支持板２６の開口３４）は、ウェイト２７がＸ軸ストッパ２８により規定される左右方向の移動限界位置に達し、かつＹ軸ストッパ２９により規定される前後方向の移動限界位置に達した場合でも、上段支持板１４の開口３２及び中段支持板２１の開口３３と重なる領域Ｒを残す。この領域Ｒにより、高圧ケーブル１２を十分な間隙をもって挿通可能であり、したがって、タワー３の頂部３ａに支持した電気設備からタワー３内を下方に延びる高圧ケーブル１２を無理なく避けつつ制振装置１３を設置することができる。   Referring to FIG. 5, the opening 31 of the weight 27 (and the opening 34 of the lower support plate 26) reaches the movement limit position in the left-right direction defined by the X-axis stopper 28 and is defined by the Y-axis stopper 29. Even when the movement limit position in the front-rear direction is reached, the region R that overlaps the opening 32 of the upper support plate 14 and the opening 33 of the middle support plate 21 remains. The region R allows the high-voltage cable 12 to be inserted with a sufficient gap. Therefore, the vibration control device 13 avoids the high-voltage cable 12 extending downward in the tower 3 from the electrical equipment supported on the top 3a of the tower 3 without difficulty. Can be installed.

以上説明したように、上記実施形態における風力発電装置１は、基礎２上に設置されたタワー３と、前記タワー３の頂部３ａに支持されたナセル４と、前記ナセル４の正面に支持されたロータヘッド５と、前記タワー３の上部又は前記ナセル４に設置されたマスダンパー型の制振装置１３とを備えるものであって、前記制振装置１３が、前記タワー３の軸心Ｃを横断するように配置されたウェイト２７を有し、前記ウェイト２７に、前記ナセル４内の発電機７から前記制振装置１３よりも下方に配置された発電制御盤１１に向けて延びる高圧ケーブル１２を挿通する開口３１が形成されるものである。   As described above, the wind turbine generator 1 in the above embodiment is supported on the tower 3 installed on the foundation 2, the nacelle 4 supported on the top 3 a of the tower 3, and the front surface of the nacelle 4. A rotor head 5 and a mass damper type damping device 13 installed in the upper part of the tower 3 or the nacelle 4, wherein the damping device 13 crosses the axis C of the tower 3. A high-voltage cable 12 extending from the generator 7 in the nacelle 4 toward the power generation control panel 11 disposed below the vibration damping device 13. An opening 31 to be inserted is formed.

また、上記実施形態における制振装置１３は、基礎２上に設置されたタワー３と、前記タワー３の頂部３ａに支持された発電機７とを備える風力発電装置１の上部に設けられるマスダンパー型のものであって、前記タワー３の軸心Ｃを横断するように配置されたウェイト２７を有し、前記ウェイト２７に、前記発電機７から当該制振装置１３よりも下方に配置された発電制御盤１１に向けて延びる高圧ケーブル１２を挿通する開口３１が形成されるものである。   Further, the vibration damping device 13 in the above embodiment is a mass damper provided on the top of the wind turbine generator 1 including the tower 3 installed on the foundation 2 and the generator 7 supported on the top 3 a of the tower 3. A weight 27 disposed so as to cross the axis C of the tower 3, and disposed on the weight 27 from the generator 7 below the damping device 13. An opening 31 through which the high-voltage cable 12 extending toward the power generation control panel 11 is inserted is formed.

上記構成によれば、制振装置１３の配置スペースの少ない風力発電装置のようなタワー状建造物において、制振装置１３のウェイト２７をタワー３の軸心Ｃを横断するように配置したプレート状としてその容量を確保できると共に、タワー３の頂部３ａに支持した発電機７から制振装置１３よりも下方に配置した発電制御盤１１に向けて延びる高圧ケーブル１２を避けて前記ウェイト２７を配置でき、もってタワー状建造物にマスダンパー型の制振装置１３を効率よく設置することができる。   According to the above configuration, in a tower-like building such as a wind power generator with a small arrangement space for the vibration damping device 13, the weight 27 of the vibration damping device 13 is arranged so as to cross the axis C of the tower 3. The weight 27 can be disposed avoiding the high-voltage cable 12 extending from the generator 7 supported on the top 3a of the tower 3 toward the power generation control panel 11 disposed below the vibration damping device 13. Therefore, the mass damper type damping device 13 can be efficiently installed in the tower-like structure.

なお、本発明は上記実施形態に限られるものではなく、例えば、外力（アクチュエータ）を用いずにマスに制振に適した動きをさせるパッシブ制振を行う制振装置を採用してもよい。
これは、例えば前記上段支持板１４と中段支持板２１とを、左右に揺動自在なＸ軸振り子を介して連結すると共に、前記Ｘ軸振り子の振動周期を調節するＸ軸ダンパー手段を設け、かつ前記中段支持板２１と下段支持板２６とを、前後に揺動自在なＹ軸振り子を介して連結すると共に、前記Ｙ軸振り子の振動周期を調節するＹ軸ダンパー手段を設けたものが考えられる。
また、上記実施形態の構成から各サーボモータ１７，２４及びボールネジ機構１８，２５を無くし、各移動脚１６，２３にスプリング等による付勢手段及びダンパー手段を連結したものも考えられる。
上記構成により、ウェイトに制振対象物の制振に適した動きをさせる（制振対象物の固有振動数に振り子の振動の周期が同調するように設定する）と共に、振動エネルギを吸収する（振動を減衰する）ことが可能となる。
そして、上記実施形態における構成は本発明の一例であり、当該発明の要旨を逸脱しない範囲で種々の変更が可能である。 Note that the present invention is not limited to the above-described embodiment, and for example, a damping device that performs passive damping that causes the mass to perform a motion suitable for damping without using an external force (actuator) may be employed.
For example, the upper support plate 14 and the middle support plate 21 are connected to each other via an X-axis pendulum that can swing left and right, and an X-axis damper means that adjusts the vibration period of the X-axis pendulum is provided. The middle support plate 21 and the lower support plate 26 are connected via a Y-axis pendulum that can swing back and forth, and Y-axis damper means for adjusting the vibration period of the Y-axis pendulum is provided. It is done.
Further, it is also conceivable that the servo motors 17 and 24 and the ball screw mechanisms 18 and 25 are eliminated from the configuration of the above embodiment, and biasing means and damper means such as springs are connected to the movable legs 16 and 23.
With the above configuration, the weight is caused to move suitable for damping the damping object (set so that the oscillation frequency of the pendulum is synchronized with the natural frequency of the damping object) and vibration energy is absorbed ( Vibration can be attenuated).
And the structure in the said embodiment is an example of this invention, A various change is possible in the range which does not deviate from the summary of the said invention.
