Description
本発明は、渦電流ブレーキ（リニア誘導モータ、誘導機等を含む）の制御装置に係り、特に、鉄道車両に装備される渦電流ブレーキ装置に関するものである。 The present invention relates to a control device for an eddy current brake (including a linear induction motor, an induction machine, and the like), and more particularly to an eddy current brake device installed in a railway vehicle.
従来、鉄道車両用渦電流ブレーキは、電磁力を利用して台車とレールとの間に非接触で制動力を作用させる。しかし、従来の渦電流ブレーキでは、所定の制動力を得るために比較的大きな励磁電力が必要であり、そのため、電源として主回路を使用したり、大規模補助電源の利用が検討されたりしていた（下記特許文献１，非特許文献１参照）。
また、初期励磁に小容量の補助回路電源を用い、その後の励磁に必要な電力を発電制動時の運動エネルギーから得る発電電力制御と、ブレーキの制動力の制御が可能な渦電流ブレーキの制御装置を、本願発明者らが提案している（下記特許文献２参照）。
Conventionally, an eddy current brake for a railway vehicle uses an electromagnetic force to apply a braking force between the carriage and the rail in a non-contact manner. However, the conventional eddy current brake requires a relatively large excitation power in order to obtain a predetermined braking force. For this reason, the main circuit is used as a power source, or the use of a large-scale auxiliary power source is being studied. (See Patent Document 1 and Non-Patent Document 1 below).
Also, a control device for an eddy current brake that uses a small-capacity auxiliary circuit power source for initial excitation and that can generate electric power necessary for the subsequent excitation from kinetic energy during dynamic braking and control of the braking force of the brake. Have been proposed by the present inventors (see Patent Document 2 below).
図４は従来の鉄道車両用渦電流レールブレーキ装置及びその周辺部分を示す図、図５は従来の渦電流レールブレーキ装置の基本構成を示すブロック図、図６はその渦電流レールブレーキ装置の基本的な原理を示す模式図である。
図４に示すように、鉄道車両用渦電流レールブレーキ装置は、励磁極としてリニア誘導モータの電機子を適用しており、一方のレール１２１に対向するように第１の電機子１１１が配置され、他方のレール１２２に対向するように第２の電機子１１１′が配置される。これらの電機子１１１，１１１′は、コア（磁芯）に形成された複数の溝に巻線を巻いて構成される直線状の電磁石であり、車輪１１３を回転可能に支持する台車１１４または車輪支持点である軸箱に固定されている。
FIG. 4 is a view showing a conventional eddy current rail brake device for a railway vehicle and its peripheral portion, FIG. 5 is a block diagram showing a basic configuration of the conventional eddy current rail brake device, and FIG. 6 is a basic view of the eddy current rail brake device. It is a schematic diagram which shows a general principle.
As shown in FIG. 4, the eddy current rail brake device for a railway vehicle uses a linear induction motor armature as an excitation pole, and a first armature 111 is arranged so as to face one rail 121. The second armature 111 ′ is arranged so as to face the other rail 122. These armatures 111 and 111 ′ are linear electromagnets configured by winding a plurality of grooves formed in a core (magnetic core), and a carriage 114 or a wheel that rotatably supports the wheel 113. It is fixed to the axle box which is a support point.
図５に示すように、電源回路とその制御方法としては、ＶＶＶＦインバータを使用した発電制動を用いている。１台の台車１１４に電機子１１１，１１１′が、もう１台の台車（図示なし）に電機子１１２，１１２′が装備されている。
なお、図５において、１１１，１１１′，１１２，１１２′は電機子、１２１はＰＷＭインバータ、１２２は補助電源装置、１２３はスイッチ、１２４はダイオード、１２５はＰＷＭインバータの接地、１２６はＰＷＭインバータ１２１からの出力電流の電流検出器、Ｉｕ，Ｉｖ，Ｉｗは電流検出器１２６からの３相出力電流値、１２７は制御回路、Ｔｕ，Ｔｖ，Ｔｗは制御回路１２７からの３相出力電圧パターン、Ｖdc refは制御回路１２７へ入力される直流電圧設定値、Ｉref 2 は制御回路１２７へ入力される制動力指令値、Ｖelは制御回路１２７へ入力される実速度である。
As shown in FIG. 5, power generation braking using a VVVF inverter is used as a power supply circuit and its control method. One carriage 114 is equipped with armatures 111 and 111 ', and the other carriage (not shown) is equipped with armatures 112 and 112'.
5, 111, 111 ′, 112, 112 ′ are armatures, 121 is a PWM inverter, 122 is an auxiliary power supply device, 123 is a switch, 124 is a diode, 125 is a ground of the PWM inverter, and 126 is a PWM inverter 121. Current detector of output current from Iu, Iv, Iw are three-phase output current values from current detector 126, 127 is a control circuit, Tu, Tv, Tw are three-phase output voltage patterns from control circuit 127, V dc ref is a DC voltage set value input to the control circuit 127, I ref 2 is a braking force command value input to the control circuit 127, and V el is an actual speed input to the control circuit 127.
図６においては、説明を簡単にするために、片側の電機子１１１及び片側のレール１２１のみを示して、渦電流ブレーキ装置の基本的な原理について説明する。鉄道車両は、レール１２１上を走行することにより、運動エネルギーを蓄積している。そこで、鉄道車両の走行速度を減少させたい場合に、電機子１１１の巻線に交流電流を流すことにより交流磁界を発生させる。この磁界により、電機子１１１の一端からレール１２１内を貫通して電機子１１１の他端に戻る磁束が発生し、レール１２１内に渦電流が生じる。鉄道車両の移動と共に磁束もレール１２１内を移動するが、レール１２１内の渦電流は磁束の変化を妨げようとするので、電機子１１１とレール１２１との間にブレーキ力が発生する。 In FIG. 6, for simplicity of explanation, only the armature 111 on one side and the rail 121 on one side are shown, and the basic principle of the eddy current brake device will be described. The railway vehicle accumulates kinetic energy by traveling on the rail 121. Therefore, when it is desired to reduce the traveling speed of the railway vehicle, an AC magnetic field is generated by passing an AC current through the windings of the armature 111. This magnetic field generates a magnetic flux that passes through the rail 121 from one end of the armature 111 and returns to the other end of the armature 111, and an eddy current is generated in the rail 121. As the railcar moves, the magnetic flux also moves in the rail 121. However, since the eddy current in the rail 121 tries to prevent the magnetic flux from changing, a braking force is generated between the armature 111 and the rail 121.
ここでは、渦電流ブレーキ装置は、図５に示すように、き電系の主回路とは切り離され、例えば、直流１００Ｖの補助電源装置１２２からの電源が供給される。これにより、き電系や主回路に故障が生じた場合であっても、ブレーキシステムに影響が及ばないようにしている。 Here, as shown in FIG. 5, the eddy current brake device is separated from the main circuit of the feeder system, and is supplied with power from, for example, the auxiliary power device 122 of DC 100V. This prevents the brake system from being affected even when a failure occurs in the feeder system or main circuit.
しかしながら、上記した渦電流ブレーキの制御装置では、小容量とはいえ、車上の補助電源回路に接続することが必要であり、配線その他、艤装上の制約を受ける。
本発明は、上記状況に鑑みて、蓄電池を搭載するのみでその他の電源を要しない鉄道車両用渦電流ブレーキ装置を提供することを目的とする。
However, although the eddy current brake control device described above has a small capacity, it needs to be connected to an auxiliary power circuit on the vehicle and is subject to restrictions on wiring and other equipment.
In view of the above situation, an object of the present invention is to provide an eddy current brake device for a railway vehicle that only includes a storage battery and does not require any other power source.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a diagram showing an eddy current rail brake device and its peripheral portion according to the present invention, and FIG. 2 is a block diagram showing a basic configuration of the eddy current rail brake device according to a first embodiment of the present invention.
In FIG. 1, 1 is a small capacity storage battery, 2 is a PWM inverter, 3 is a current detector for output current from the PWM inverter, 4, 4 'is a first armature, and 5 and 5' are second armatures. , Iu, Iv, Iw are three-phase output current values from the current detector 3, 6 is a control circuit, Tu, Tv, Tw are three-phase output voltage patterns input from the control circuit 7 to the PWM inverter 3, and 7 is a storage battery. 1 is a remaining power storage value (SOC), 11 is a rail, 12 is a carriage, 13 is a wheel, V dc ref is a DC voltage setting value input to the control circuit 6, and I ref 2 is a control voltage input to the control circuit 6. This is a power command signal.
図２に示すように、渦電流式レールブレーキ装置は、従来のようなき電系の主回路や、補助電源装置からの電源に代えて小容量の蓄電池１が搭載される。つまり、系からは独立した小容量の蓄電池１からＰＷＭインバータ２に電力が供給される。これにより、き電系の主回路や、補助電源装置に故障が生じてもブレーキシステムとしての信頼性を損なうことはない。 As shown in FIG. 2, the eddy current type rail brake device is equipped with a storage battery 1 having a small capacity in place of a conventional main circuit of a feeding system and a power source from an auxiliary power supply device. That is, electric power is supplied to the PWM inverter 2 from the small-capacity storage battery 1 independent of the system. As a result, even if a failure occurs in the main circuit of the feeder system or the auxiliary power supply device, the reliability as a brake system is not impaired.
ＰＷＭインバータ２は、図示しないが、車輪１３を介してレール１１に接地されており、蓄電池１の直流電圧に基づいて、第１の電機子４、４′及び第２の電機子５，５′に交流電流を流し、第１の電機子４、４′及び第２の電機子５，５′を励磁してブレーキ力を発生させる。
第１の電機子４、４′及び第２の電機子５，５′の巻線に流れる電流を検出するためにＰＷＭインバータ２の出力側に電流検出器３が配置され、検出された３相出力電流値Ｉｕ，Ｉｖ，Ｉｗが制御回路６へ入力される。制御回路６は電流検出器３により検出された３相出力電流値Ｉｕ，Ｉｖ，Ｉｗに基づいて、第１の電機子４、４′及び第２の電機子５，５′に流れる電流ベクトルを検出し、制動力指令信号Ｉref 2 と直流電圧設定値Ｖdc refに従って、第１の電機子４、４′及び第２の電機子５，５′に供給する３相出力電圧パターンＴｕ，Ｔｖ，Ｔｗを算出し、ＰＷＭインバータ２に出力する。
Although not shown, the PWM inverter 2 is grounded to the rail 11 via the wheel 13, and based on the DC voltage of the storage battery 1, the first armature 4, 4 ′ and the second armature 5, 5 ′. An alternating current is applied to the first armature 4 to excite the first armature 4, 4 ′ and the second armature 5, 5 ′ to generate a braking force.
A current detector 3 is arranged on the output side of the PWM inverter 2 to detect the current flowing through the windings of the first armature 4, 4 ′ and the second armature 5, 5 ′. Output current values Iu, Iv, and Iw are input to the control circuit 6. Based on the three-phase output current values Iu, Iv, Iw detected by the current detector 3, the control circuit 6 determines the current vectors flowing through the first armatures 4, 4 'and the second armatures 5, 5'. Three-phase output voltage patterns Tu and Tv that are detected and supplied to the first armatures 4, 4 ′ and the second armatures 5, 5 ′ in accordance with the braking force command signal I ref 2 and the DC voltage set value V dc ref , Tw are calculated and output to the PWM inverter 2.

さらに、蓄電池１の放電に備えて蓄電池１の蓄電残量値７をモニタし、その蓄電残量値７が予め設定された一定値を下回った場合、鉄道車両の走行中に渦電流ブレーキを動作させ、自車の蓄電池１に充電するように構成している。
In this way, the small-capacity storage battery 1 is mounted on the control device for the eddy current rail brake, and the storage battery 1 is configured to operate completely independently as a power supply circuit.
Further, in preparation for the discharge of the storage battery 1, the remaining power level 7 of the storage battery 1 is monitored, and when the remaining power level 7 falls below a preset constant value, the eddy current brake is operated while the railway vehicle is running. The storage battery 1 of the own vehicle is charged.

Furthermore, in preparation for the discharge of the storage battery 1, the remaining battery charge value 7 of the storage battery is monitored, and when the remaining battery charge value 7 falls below a certain value, the eddy current disk brake is operated while the railway vehicle is running, The vehicle storage battery 1 is configured to be charged.
According to this embodiment, it can be mounted on a vehicle without a motor, and since it is a non-contact type brake, the brake disk is not consumed and a brake pad is not necessary.
上記したように、本発明によれば、図２に示す通り、従来の補助回路に置き換えて、蓄電池１を搭載する。また、蓄電池１から蓄電残量値７が出力されており、予め設定された一定値を下回った場合、走行時又はブレーキ時に渦電流ブレーキ装置により発電された電力の一部を蓄電池１への充電にあてる。
なお、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づいて種々の変形が可能であり、これらを本発明の範囲から排除するものではない。
As described above, according to the present invention, as shown in FIG. 2, the storage battery 1 is mounted in place of the conventional auxiliary circuit. In addition, when the remaining battery charge value 7 is output from the storage battery 1 and falls below a preset constant value, a part of the electric power generated by the eddy current brake device during running or braking is charged to the storage battery 1. Hit it.
In addition, this invention is not limited to the said Example, A various deformation | transformation is possible based on the meaning of this invention, and these are not excluded from the scope of the present invention.
