Description

자기부상열차의 보조전원장치{AUXILIARY POWER SUPPLY OF MAGNETICALLY LEVITATED VEHICLE}AUXILIARY POWER SUPPLY OF MAGNETICALLY LEVITATED VEHICLE BACKGROUND OF THE INVENTION [0001]

본 발명은 자기부상열차(MAGLEV)의 보조전원장치에 관한 것으로, 특히, 지상전원공급장치의 고장 시 또는 차 내 전원 계통의 고장 시에도 부상용 전원을 정상적으로 제공하여, 지상전원공급장치의 고장 시 또는 차 내 전원 계통의 고장 시에도 차량이 안정적으로 부상을 유지하도록 하는 보조전원장치에 관한 것이다.The present invention relates to an auxiliary power supply for a magnetic levitation train (MAGLEV), and more particularly to an auxiliary power supply for a magnetic levitation train (MAGLEV), particularly when a ground power supply fails or when a power supply system in a car fails, Or an auxiliary power source device that allows the vehicle to stably maintain a floating state even in the event of a failure of the power source system in the car.

일반적으로 자기부상열차는 자기력을 이용해 차량을 선로 위에 부상시켜 움직이는 열차로, 선로와의 접촉이 없어 소음과 진동이 매우 적고 고속도를 유지할 수 있다.Generally, a magnetic levitation train is a train that moves by moving a vehicle on a track by using magnetic force. It does not come into contact with a track, so noise and vibration are very few and high speed can be maintained.

이와 같은 자기부상열차는 차 내에 3상 교류 380/220V, 직류 100V 등의 일반 전원 및 열차를 부상시키는데 필요한 직류 300V 전원이 필요하다.Such magnetic levitation trains require a 300 V AC power source such as three-phase alternating current 380 / 220V, DC 100V, and a DC power source for raising a train.

이와 관련하여, 도 1은 종래의 기술에 따른 자기부상열차의 전원장치의 일 실시 예를 나타낸 블록도로, 메인 3상 인버터(main 3-phase inverter)(10), 변압기(12), 필터(filter)(14), 밧데리 충전기(16), 밧데리(18), 및 교류/직류 변환기(20)로 구성된다.In this regard, FIG. 1 is a block diagram showing an embodiment of a power supply device for a magnetic levitation train according to the prior art, and includes a main three-phase inverter 10, a transformer 12, a filter A battery 14, a battery charger 16, a battery 18, and an AC / DC converter 20.

동 도면에 있어서, 메인 3상 인버터(10)는 직류 1500V의 가선전압을 받아 변환하여 150kW의 3상 교류를 출력해서 변압기(12)에 공급한다.In the figure, the main three-phase inverter 10 receives a line voltage of 1500 V DC and outputs a three-phase alternating current of 150 kW to the transformer 12.

변압기(12)는 메인 3상 인버터(10)로부터 제공되는 3상 교류를 두 가지의 3상 교류로 변압하여 필터(14) 및 교류/직류 변환기(20)로 각기 공급한다.The transformer 12 transforms the three-phase alternating current provided from the main three-phase inverter 10 into two three-phase alternating currents and supplies them to the filter 14 and the AC / DC converter 20, respectively.

필터(14)는 변압기(12)로부터 공급되는 3상 교류에서 고조파 성분을 제거하고, 일반 전원 380/220V의 3상 교류(U, V, W)를 출력한다.The filter 14 removes the harmonic components from the three-phase alternating current supplied from the transformer 12 and outputs the three-phase alternating current (U, V, W) of the general power supply 380/220 volts.

밧데리 충전기(16)는 필터(14)로부터 제공되는 380/220V의 3상 교류를 변환하여 직류 100V를 출력해서 밧데리(18)로 공급한다.The battery charger 16 converts the three-phase alternating current of 380/220 volts supplied from the filter 14, and outputs a DC voltage of 100 V to the battery 18.

밧데리(18)는 밧데리 충전기(16)로부터 공급되는 직류 100V를 사용해서 충전했다가 직류 100V의 일반 전원을 출력한다.The battery 18 is charged using the direct current 100 V supplied from the battery charger 16, and then outputs a general power of 100 V DC.

교류/직류 변환기(20)는 변압기(12)로부터 공급되는 3상 교류를 변환하여 100kW 직류 300V를 출력해서 병렬연결된 복수의 부상용 전력 예로, 제 1 내지 제 8 부상용 전력으로 공급한다. 이때 제 1 내지 제 8 부상용 전력은 열차를 부상시키기 위한 구동전력으로 사용된다.The AC / DC converter 20 converts the three-phase AC supplied from the transformer 12 and supplies 100 kW DC 300 V to the first to eighth levitation powers, for example, a plurality of parallel-connected floating powers. At this time, the first to eighth floating powers are used as driving power for raising the train.

그러나 이와 같은 종래의 기술에 있어서는 지상전원공급장치의 고장 시 또는 차내 직류 300V 계통의 고장 시 부상용 전력이 공급되지 못하기 때문에 차량의 부 상을 유지시키지 못하는 결점이 있다.However, in such a conventional technique, there is a drawback that when the ground power supply device fails, or when a 300V DC system failure occurs, the floating power can not be supplied and the vehicle can not be maintained.

또한, 교류/직류 변환기(20)가 복수의 부상용 전력을 출력해야 하기 때문에 교류/직류 변환기(20)는 물론, 이와 관련된 메인 3상 인버터(10) 및 변압기(12)의 용량도 과도할 수밖에 없다. 따라서 메인 3상 인버터(10), 변압기(12), 및 교류/직류 변환기(20)의 부피와 중량이 클 수밖에 없는 문제점이 있다.In addition, since the AC / DC converter 20 must output a plurality of floating powers, the capacity of the main three-phase inverter 10 and the transformer 12 related to the AC / DC converter 20 as well as the AC / none. Therefore, the volume and weight of the main three-phase inverter 10, the transformer 12, and the AC / DC converter 20 are inevitably large.

본 발명은 전술한 과제를 해결하기 위하여 안출한 것으로, 지상전원공급장치의 고장 시 또는 차 내 전원 계통의 고장 시에도 부상용 전원을 정상적으로 제공하여, 지상전원공급장치의 고장 시 또는 차 내 전원 계통의 고장 시에도 차량이 안정적으로 부상을 유지하도록 하는 자기부상열차의 보조전원장치를 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a floating power supply normally in case of failure of a ground power supply or failure of a power supply system in a car, And to provide an auxiliary power unit for a magnetic levitation train which allows a vehicle to stably maintain a floating state even in the event of a failure of the vehicle.

이와 같은 목적을 달성하기 위하여,In order to achieve this object,

본 발명의 일 형태에 따르면, 직류 가선전압을 사용하는 자기부상열차의 전원장치로서, 상기 직류 가선전압을 변환하여 밧데리 충전용 직류를 출력하는 밧데리 충전기; 상기 밧데리 충전기로부터 제공되는 밧데리 충전용 직류를 사용해서 부상용 전력을 충전하는 밧데리; 상기 직류 가선전압을 각기 변환하여 각 부상용 전 력을 각각 출력하는 복수의 직류/직류 변환기; 상기 밧데리의 출력단과 상기 복수의 직류/직류 변환기의 각 출력단 사이에 각기 접속되고, 상기 밧데리의 출력이 상기 복수의 직류/직류 변환기의 각 출력에 대해 보조전원으로 각기 제공되도록 하는 복수의 다이오드를 포함하는 것을 특징으로 한다.According to an aspect of the present invention, there is provided a power supply device for a magnetic levitation train using a direct current line voltage, the device comprising: a battery charger for converting a direct current voltage to output a direct current for charging the battery; A battery for charging the floating electric power using the battery charging DC supplied from the battery charger; A plurality of DC / DC converters for respectively converting the DC line voltage and outputting respective floating powers; And a plurality of diodes connected between an output terminal of the battery and each output terminal of the plurality of DC / DC converters, wherein the output of the battery is provided as an auxiliary power source for each output of the plurality of DC / DC converters .

본 발명에서 상기 복수의 다이오드는 상기 밧데리의 출력단에서 상기 복수의 직류/직류 변환기의 각 출력단으로 각기 순방향 접속된 것을 특징으로 하는 자기부상열차의 보조전원장치.Wherein the plurality of diodes are forward-connected to the output terminals of the battery and to the output terminals of the plurality of DC / DC converters, respectively.

본 발명은, 지상전원공급장치의 고장 시 또는 차 내 전원 계통의 고장 시에도 부상용 전원을 정상적으로 제공하기 때문에, 지상전원공급장치의 고장 시 또는 차 내 전원 계통의 고장 시에도 차량이 안정적으로 부상이 유지되는 효과가 있다.The present invention provides a floating power supply normally in the event of a failure of the ground power supply or failure of the power supply system in the vehicle so that the vehicle can be stably wound up even when the ground power supply fails, Is maintained.

또한, 복수의 직류/직류 변환기가 직류 가선전압을 직접 각기 변환하여 몇 개의 부상용 전력을 각각 출력하기 때문에, 별도의 교류용 변압기가 필요 없고 복수의 직류/직류 변환기의 용량이 작아도 되므로 전체적인 부피와 중량을 줄일 수 있는 장점이 있다.In addition, since a plurality of DC / DC converters directly convert DC direct-current voltages and output a few floating powers, respectively, there is no need for a separate AC transformer and the capacity of a plurality of DC / DC converters may be small, It has the advantage of reducing weight.

이하, 첨부된 도면을 참조하여 본 발명에 따른 실시 예를 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 자기부상열차의 보조전원장치의 일 실시 예를 나타낸 블록도로, 교류 전원용 직류/직류 변환기(30), 3상 인버터(32), 필터(34), 밧데리 충전기(36), 밧데리(38), 제 1 내지 제 4 직류/직류 변횐기(40 내지 46), 및 제 1 내지 제 4 다이오드(D1 내지 D4)로 구성된다.FIG. 2 is a block diagram illustrating an embodiment of an auxiliary power source for a magnetic levitation train according to the present invention. The AC / DC converter 30, the three-phase inverter 32, the filter 34, the battery charger 36, A battery 38, first to fourth DC / DC converters 40 to 46, and first to fourth diodes D1 to D4.

동 도면에 있어서, 교류 전원용 직류/직류 변환기(30)는 직류 가선전압을 변환하여 교류 전원 발생을 위한 25kW의 직류를 출력해서 3상 인버터(32)로 제공한다.In the figure, an AC power supply DC / DC converter 30 converts a DC line voltage and outputs a DC power of 25 kW for generation of AC power, and provides it to the three-phase inverter 32.

3상 인버터(32)는 교류 전원용 직류/직류 변환기(30)로부터 공급되는 직류를 변환하여 3상 교류를 출력해서 필터(34)로 공급한다.The three-phase inverter 32 converts the direct current supplied from the alternating-current power supply direct-current / direct current converter 30 and outputs the three-phase alternating current to the filter 34.

필터(34)는 3상 인버터(32)로부터 제공되는 3상 교류에서 고조파 성분을 제거하고, 일반 전원 380/220V의 3상 교류(U, V, W)를 출력한다.The filter 34 removes the harmonic components from the three-phase alternating current provided from the three-phase inverter 32 and outputs three-phase alternating current (U, V, W) of a general power source of 380/220 volts.

밧데리 충전기(36)는 직류 가선전압을 변환하여 25kW의 밧데리 충전용 직류를 출력해서 밧데리(38)로 공급한다.The battery charger 36 converts the direct current voltage to output a 25 kW direct current for battery charging and supplies it to the battery 38.

밧데리(38)는 밧데리 충전기(36)로부터 제공되는 밧데리 충전용 직류를 사용해서 충전하고, 100V의 일반 전원인 제 1 직류 및 300V의 부상용 전력인 제 2 직류를 각기 출력한다. 상기 제 2 직류는 각각의 제 1 내지 제 4 다이오드(D1 내지 D4)를 통해 제 1 내지 제 4 직류/직류 변환기(40 내지 46)의 각 출력단에 각기 제공된다. 이때 각각의 제 1 내지 제 4 다이오드(D1 내지 D4)는 밧데리(38)의 출력단에서 제 1 내지 제 4 직류/직류 변환기(40 내지 46)의 각 출력단으로 각기 순방향 접속되어, 제 1 내지 제 4 직류/직류 변환기(40 내지 46)의 출력단에서 밧데리(38)의 출력단으로 전류가 흐르는 것 즉, 역전류를 방지한다.The battery 38 is charged using the battery charging DC supplied from the battery charger 36 and outputs the first DC which is the normal power of 100V and the second DC which is the floating power of 300V. The second direct current is supplied to each output terminal of the first to fourth direct current / direct current converters 40 to 46 through the respective first to fourth diodes D1 to D4. At this time, the first to fourth diodes D1 to D4 are respectively forward-connected to the output terminals of the first to fourth DC / DC converters 40 to 46 at the output terminal of the battery 38, Current flows from the output terminal of the DC / DC converters 40 to 46 to the output terminal of the battery 38, that is, the reverse current is prevented.

제 1 내지 제 4 직류/직류 변환기(40 내지 46)는 직류 가선전압을 각기 변환하여 각 부상용 전력을 각각 출력한다.The first to fourth DC / DC converters 40 to 46 convert DC direct-current voltages to output respective floating powers, respectively.

예로, 제 1 직류/직류 변환기(40)는 25kW의 제 1, 제 2 부상용 전력(300V)을 출력하고, 제 2 직류/직류 변환기(42)는 25kW의 제 3, 제 4 부상용 전력(300V)을 출력하고, 제 3 직류/직류 변환기(44)는 25kW의 제 5, 제 6 부상용 전력(300V)을 출력하며, 제 4 직류/직류 변환기(46)는 25kW의 제 7, 제 8 부상용 전력(300V)을 출력한다.For example, the first DC / DC converter 40 outputs 25 kW of the first and second floating power (300 V), and the second DC / DC converter 42 outputs 25 kW of the third and fourth floating powers ( DC converter 44 outputs 25 kW of the fifth and sixth in-phase power (300 V), and the fourth DC / DC converter 46 outputs the seventh and eighth And outputs floating power (300 V).

이와 같은 본 발명에서 지상전원공급장치의 고장에 따라 가선전압이 공급되지 않을 경우, 제 1 내지 제 4 직류/직류 변환기(40 내지 46)도 부상용 전력을 출력하지 못한다. 이때 밧데리(38)에 의해 특정 시간 예로, 30초 동안 각 부상용 전원이 공급되어 열차의 부상이 유지된다. 물론, 30초 이내에 가선전압이 정상적으로 공급되어야 열차의 부상이 계속 유지된다.In the present invention, when the ground voltage is not supplied due to the failure of the ground power supply, the first to fourth DC / DC converters 40 to 46 also fail to output the floating power. At this time, each lifting power source is supplied by the battery 38 for 30 seconds at a specific time, for example, so that the lifting of the train is maintained. Of course, if the line voltage is normally supplied within 30 seconds, the train will continue to be injured.

또한, 제 1 내지 제 4 직류/직류 변환기(40 내지 46) 중 어느 하나 정도는 고장이 발생하더라도 나머지 제 4 직류/직류 변환기가 부상용 전원을 정상적으로 출력한다면, 결국 열차의 여러 곳에서 발생하는 부상력 중에 어느 한 곳에만 부상력이 상실되는 것과 같으므로 열차는 어느 정도 안정적인 부상을 유지할 수 있다.If any one of the first to fourth DC / DC converters 40 to 46 generates a fault, the remaining DC / DC converter outputs the inrush current normally. In this case, The train is able to maintain a certain degree of stable injuries because it is the same as if the levitation force is lost in any one of the forces.
