본 발명은 전력을 동력원으로 하는 전동차의 유도전력전송 급전 시스템에 관한 것으로, 보다 상세하게는 전력충전을 필요로 하는 전동차가 정차 시 또는 주행 중에 각 역사와 주행선로 상에 구비된 충전베이와 충전섹션에서 물리적 접촉 없이 급속 충전을 수행하는 전동차의 유도 급전 설비 시스템에 관한 것이다.The present invention relates to an electric power feeding system for induction power transmission of an electric vehicle using power as a power source, and more particularly, a charging bay and a charging section provided on each station and a driving track when an electric vehicle requiring electric power charging is stopped or driving. It relates to an induction feeder system of an electric vehicle that performs a quick charging without physical contact.

일반적으로 전기차량은 전기를 전력공급원으로 하여 운행하는 차량을 의미하며, 고전압 전류가 흐르고 있는 가선으로부터 전기에너지를 공급받아 운행하는 전동차(Electric Rail Car)와, 차량 자체에 전력공급원으로 충전이 가능한 배터리를 탑재하고 탑재된 배터리에서 공급되는 전력을 이용하여 운행하는 전기자동차로 구분된다.In general, an electric vehicle refers to a vehicle that operates by using electricity as a power source, an electric rail car that receives electric energy from a live wire flowing with a high voltage current, and a battery that can be charged as a power source to the vehicle itself. It is divided into an electric vehicle that runs by using the power supplied from the mounted battery.

전동차의 경우 가선에 의해 정해진 궤도를 따라 이동하게 되는데, 집전장치로 상부에 팬터그래프(Pantograph)를 구비하고 스프링 또는 압축공기의 힘으로 가선이 밀착되도록 밀어 올리는 가공전차선 방식과, 주행용 궤도의 상면 또는 측면에 설치된 독립적인 급전선으로부터 제3궤조 집전장치를 통해 수전하는 제3궤조식으로 나눌 수 있다. In the case of electric cars, they move along a track defined by the wire. A pantograph is provided on the upper part of the current collector, and the overhead train line system pushes up the wire to be in close contact with the force of a spring or compressed air, and the upper surface of the driving track or It can be divided into a third track type receiving power through the third track current collector from an independent feeder installed on the side.

이 중 가공전차선 방식은 팬터그래프와 트롤리선(Trolley Line), 이와 접촉하는 습동판과 지지하는 구조체, 복원스프링, 압상장치 등을 포함하여 구성되며, 제3궤조식은 집전자의 일정 압착력을 유지하기 위해 별도의 스프링을 필요로 하고 승강장, 터널, 상하행 주행에 따라 설비의 위치가 서로 반대가 되므로 양측으로 집 전자가 설치되어야 하는 등 설비 구성이 복잡하고 사용에 따른 소음이 발생한다.Among them, the overhead tramline method includes a pantograph, a trolley line, a sliding plate in contact with the support plate, a supporting structure, a restoring spring, and a pressing device, and the third trajectory is designed to maintain a constant pressing force of the current collector. Since a separate spring is required and the locations of the facilities are opposite to each other according to the platform, tunnel, and up and down driving, the collector configuration must be installed on both sides, resulting in complicated facility configuration and noise due to use.

또한, 이러한 종래의 전동차 시스템의 경우 집전설비의 물리적 접촉을 바탕으로 집전 및 급전시스템이 구성되기 때문에 전동차, 특히 전기철도의 경우 집전성능 확보를 위한 압상력 제어 기법, 집전장치의 복잡한 구성 및 고속화에 따라 빈발하는 이선으로 인한 전력품질의 저하, 습동판의 마모, 소음문제, 트롤리선의 변형에 따른 파손 절단의 우려 등이 있으므로 장기 사용에 따른 유지보수에 많은 시간과 비용이 소요되게 된다.In addition, in the conventional electric vehicle system, since the current collecting and feeding system is configured based on the physical contact of the current collecting facility, the rolling force control technique for securing the current collecting performance in the electric vehicle, especially the electric railway, and the complicated configuration and speeding up of the current collecting device. Accordingly, there is a risk of power quality deterioration due to frequent two wires, sliding of a sliding plate, noise problems, and a breakage of cutting due to the deformation of a trolley wire.

또한, 종래의 전동차 시스템은 전차선이 전 노선에 걸쳐 설치되고 직류급전방식은 고저항 지락에 대한 보호장치를 필요로 하며, 교류급전방식은 절연 이격거리 확보를 위해 터널 및 차량의 크기가 커지고 통신유도장해에 대한 노출영역이 확대되는 등의 문제점이 있다.In addition, in the conventional electric vehicle system, the tram line is installed all over the line, and the DC power supply method requires a protection device against a high resistance ground fault, and the AC power supply method increases the size of the tunnel and the vehicle to secure the insulation separation distance, and induces communication There are problems such as an increase in the exposure area to the solution.

상기와 같은 문제점을 해결하고자 유도전력에 의한 비접촉방식을 이용하여 전력을 공급받는 전기차량을 개발하고자 하는 시도가 있어왔다. 대한민국 특허출원 제10-2003-0072376호와 제10-2004-0014385호는 본 발명 출원인에 의해 출원된 비접촉 급전방식을 이용한 전기차량 운행시스템에 관한 것이다.

FIGS. 1 and 2 are schematic views of an entire system, and FIG. 3 is a diagram of an interior of an electric vehicle running in a power supply system. Fig. 4 is a diagram showing the configuration of Fig. 4 is a diagram showing a charging unit configured inside the electric vehicle.

도1 및 도2에 도시된 바와 같이, 본 발명 유도 급전 설비 시스템은 전동차가 정차하는 역사에 급전을 위한 역사충전베이(Station Charging Bay)(110)를 설치하고 주행선로 상에 충전섹션(Charging Zone)(120)을 구비하며, 복수의 역사충전 베이(110)와 충전섹션(120)을 연결하여 이루어진 하나의 유닛(Unit)에 전력 공급을 제어하는 전력제어장치(130)를 포함하여 구성된다. As shown in Fig. 1 and Fig. 2, the induction feeder system of the present invention installs a station charging bay 110 for feeding power in a station where the electric vehicle stops and a charging section on a driving line. (120), and includes a power control device 130 for controlling power supply to a unit (Unit) made by connecting the plurality of history charging bay 110 and the charging section 120.

여기서, 상기 역사충전베이(110)는 전동차가 역사에 정차했을 때 전력을 송전하기 위해 각 역사에 설치되며 충전섹션(120)은 주행 중인 전동차에 전력을 송전하기 위하여 주행선로의 지정된 일부 구간에 설치된다. 이로써 전동차가 역사충전베이(110)에 정차하거나 충전섹션(120)을 지나갈 때 변전소로부터 송전된 고주파 교류 전력이 전력제어장치(130)에 의해 물리적 접촉 없이 유도 작용을 통해 전동차에 전송된다. Here, the history charging bay 110 is installed in each station to transmit power when the electric vehicle stops in the history, and the charging section 120 is installed in a designated section of the running line to transmit power to the electric vehicle in operation. do. As a result, when the electric vehicle stops at the station charging bay 110 or passes the charging section 120, the high frequency AC power transmitted from the substation is transmitted to the electric vehicle through the induction action without physical contact by the power control device 130.

이때, 상기 전력제어장치(130)는 수 kHz, 수백 kW 급 규모 출력을 하나의 유닛을 구성하는 각각의 역사충전베이(110)와 충전섹션(120)에 공급하도록 이루어지되, 하나의 전력제어장치(130)로부터 전력이 공급되는 하나의 유닛은 8개의 역사충전베이(110)와 8개의 충전섹션(120)으로 구성되는 것이 바람직하다. At this time, the power control device 130 is made to supply a plurality of kHz, hundreds of kW class output to each of the history charging bay 110 and the charging section 120 constituting one unit, one power control device One unit powered from 130 is preferably composed of eight filling bays 110 and eight charging sections 120.

이렇게 구성된 본 발명 유도 급전 설비 시스템은 바람직하게는 전력제어장치(130)와 연동하면서 각 역사충전베이(110)와 충전섹션(120)에서 자동적으로 위치를 감지하여 전동차의 진입여부를 판단하는 차량감지수단(140)과, 진입한 전동차의 요구에 따라 전력급전을 선택적으로 제어하는 전력공급제어수단(150)을 더 포함할 수 있다. 즉, 역사충전베이(110)와 충전섹션(120)에는 차량감지수단(140)으로 위치감지 센서가 구비되어, 상기 역사충전베이(110) 또는 충전섹션(120)으로 전동차가 진입하는 경우 전력공급제어수단(150)은 전동차에 충전이 필요한지 여부를 판단하여 충전이 필요한 경우에만 정차 또는 주행 중인 전동차에 급전이 실행된다. 또한, 역사충전베이(110)나 충전섹션(120)으로 전동차가 진입하더라도 전동차에 충전이 필요하지 않은 경우, 전력공급제어수단(150)은 역사충전베이(110)나 충전섹션(120)으로부터 발생하는 자기 유도에너지가 전동차로 전송되지 않도록 제어한다. 따라서 충전이 수행되지 않는 상태에서 불필요하게 전력이 공급되는 전력소모를 감소시킬 수 있다. The present invention induction feed facility system configured as described above is preferably connected to the power control device 130, the vehicle sensing to determine whether the entrance of the electric vehicle by automatically detecting the position in each history charging bay 110 and the charging section 120. Means 140 and the power supply control means 150 for selectively controlling the power supply in accordance with the request of the entered electric vehicle may be further included. That is, the history charging bay 110 and the charging section 120 is provided with a position detection sensor as the vehicle detecting means 140, the power supply when the electric vehicle enters the history charging bay 110 or the charging section 120. The control means 150 determines whether the electric vehicle needs to be charged, and the electric power is supplied to the stationary or driving electric vehicle only when the electric vehicle is required to be charged. In addition, even when the electric vehicle enters the history charging bay 110 or the charging section 120, when the electric vehicle does not need charging, the power supply control means 150 is generated from the history charging bay 110 or the charging section 120. The magnetic induction energy is controlled so as not to be transmitted to the electric vehicle. Therefore, it is possible to reduce power consumption in which power is unnecessarily supplied in a state where charging is not performed.

위와 같이 이루어진 본 발명 실시예에서는 유도전력방식에 의해 전동차로 전력이 전달되므로 가공전차선이나 3궤조식에서와 같이 주행궤도를 따라 노선 내에 연속적으로 설치되어야 하는 급전선 및 노출된 전기장치 요소가 제거되어, 물리적 접촉에 의한 단락사고의 위험이 제거될 뿐 아니라 환경과 미관적 측면에서도 장점을 가지게 된다.In the embodiment of the present invention made as described above, the electric power is transmitted to the electric vehicle by the induction electric power method, so that the feeder line and the exposed electric device element which are to be continuously installed in the line along the traveling trajectory as in the overhead train line or the three-track type are removed, thereby physically Not only does the risk of short-circuit accidents caused by contact eliminate, but it also has advantages in terms of environment and aesthetics.

또한, 주행 중에 급전을 지속적으로 받게 되면 대전력 시스템에서는 설비의 규모가 너무 커지게 되지만, 본 발명 실시예에서는 충전섹션(120)이 주행선로의 일부구간에만 설치되므로 터널 등의 절연이격거리를 최소화하여 시스템 설비를 축소하고 운행시스템을 적절하게 운영할 수 있게 된다.In addition, if the power supply is continuously received while driving, the size of the facility becomes too large in the large power system, but in the embodiment of the present invention, since the charging section 120 is installed only in a section of the driving line, the insulation distance such as a tunnel is minimized. In this way, the system equipment can be reduced and the operation system can be properly operated.

상기와 같이 구성된 유도 급전 설비 시스템에서 전력을 공급받아 운행하는 전동차는 도3과 같이 역사충전베이(110)나 충전섹션(120)에 흐르는 고주파 교류전압과의 전자기 유도 작용에 의해 발생된 교류전압을 발생시키는 전력집전부(210), 전력집전부(210)로부터 발생된 교류전압을 직류전압으로 정류시키고 평활시켜 후술하는 충전부(230)와 전력변환부(240)로 공급하는 정류평활부(220), 직류전압을 저장하였다가 전동차가 작동하는데 있어 전력을 공급하는 충전부(230) 및 공급되는 직류전압을 부하의 동작전압에 맞게 변환하여 전동기(250)에 공급하는 전력변환부(240)를 포함하여 구성된다.The electric vehicle that is supplied with power in the induction feed facility system configured as described above is configured to generate an AC voltage generated by an electromagnetic induction action with the high frequency AC voltage flowing in the history charging bay 110 or the charging section 120 as shown in FIG. 3. The rectifier smoothing unit 220 rectifies and smoothes the AC voltage generated from the power collector 210 and the power collector 210 to the DC voltage to supply the charging unit 230 and the power converter 240 to be described later. In addition, the charging unit 230 stores the DC voltage and supplies electric power to operate the vehicle, and the power conversion unit 240 converts the supplied DC voltage according to the operating voltage of the load and supplies the motor 250 to the motor 250. It is composed.

전력집전부(210)는 역사나 주행선로에 설치된 역사충전베이(110)와 충전섹션(120)과의 거리를 고려하여 전동차의 저면에 구성되어, 역사충전베이(110)나 충 전섹션(120)을 지날 때 전자유도작용에 의해 발생되는 교류전압을 이용하여 전동차의 운행 및 탑재된 충전부(230)에 충전이 이루어지고, 그 이외의 주행선로를 운행할 때는 저장되어 있는 충전부(230)의 전력을 이용하여 전동차가 운행되도록 한다.The electric power collector 210 is configured on the bottom of the electric vehicle in consideration of the distance between the history charging bay 110 and the charging section 120 installed in the history or the driving line, the history charging bay 110 or the charging section 120. Charging is performed on the running and mounted charging unit 230 of the electric vehicle by using the AC voltage generated by the electromagnetic induction when passing, and when driving the other running line, the stored power of the charging unit 230 is stored. To make the electric car run.

정류평활부(220)는 전력집전부(210)에서 발생된 교류전압을 직류전압으로 정류하고, 평활하는 것으로 브리지 다이오드, 코일, 콘덴서 등으로 이루어진 공지의 정류회로와 평활회로를 이용한다. 또한, 상기 정류평활부(220)는 바람직하게는 유도된 전력의 누설 및 무효전력분을 보상하기 위한 공진형 보상회로(Resonant Compensation Circuit)를 더 포함할 수 있다.The rectifying smoother 220 rectifies and smoothes the AC voltage generated by the power collector 210 to a DC voltage, and uses a known rectifying circuit and a smoothing circuit including a bridge diode, a coil, a capacitor, and the like. In addition, the rectifying smoother 220 may further include a resonant compensation circuit for compensating leakage of reactive power and reactive power.

이처럼 전자유도작용에 의해 발생하여 정류 평활된 직류전압은 전력변환부(240)에서 전동기(250)의 구동전원으로 변환되어 전동차를 운행시키면서, 이와 동시에 충전부(230)를 충전시켜 주행 중 충전이 이루어지도록 한다.The DC voltage generated and rectified and smoothed by the electromagnetic induction effect is converted from the power conversion unit 240 to the driving power of the electric motor 250 to drive the electric vehicle, while simultaneously charging the charging unit 230 to perform charging while driving. To lose.

이를 위해 충전부(230)는 전력을 저장하는 배터리(231), 충전시간과 방전시간을 단축하는 버퍼용 캐패시터(232) 및 충전부의 안정된 동작을 수행하는 EMS 컨트롤러(233)를 포함하여 이루어진다. To this end, the charging unit 230 includes a battery 231 for storing electric power, a buffer capacitor 232 for shortening a charging time and a discharging time, and an EMS controller 233 performing a stable operation of the charging unit.

여기서, 상기 버퍼용 캐패시터(232)는 전동차가 역사충전베이(110)에 정차하거나 충전섹션(120)을 통과하는 소정시간 동안 공급되는 전력을 일시 저장했다가, 충전섹션(120)이 설치되지 않은 구간을 주행할 때에도 전동차를 정상적으로 운행시키는 역할을 한다. 이를 위해 상기 버퍼용 캐패시터(232)는 일반 캐패시터에 비해 충전효율이 높은 울트라 캐패시터(Ultra Capacitor)로 이루어진다. 울트라 캐패시터, 혹은 슈퍼 캐패시터는 일반 재래식 캐패시터에 비해 정전용량이 300배 이상인 캐패시터로, 짧은 시간 동안 순시 첨두 전력을 공급할 수 있는 능력이 배터리의 10배 ~ 100배 이상이므로, 정전과 같은 비상시에 대비한 전력 공급수단으로 사용된다. Here, the buffer capacitor 232 temporarily stores the power supplied for a predetermined time when the electric vehicle stops in the stationary charging bay 110 or passes through the charging section 120, and the charging section 120 is not installed. Even when driving the section, it serves to operate the electric vehicle normally. To this end, the buffer capacitor 232 is formed of an ultracapacitor having a higher charging efficiency than a general capacitor. Ultracapacitors, or supercapacitors, have a capacity of 300 times more than conventional capacitors, and have the ability to supply instantaneous peak power for a short time because they are 10 to 100 times faster than batteries. Used as a power supply.

따라서 울트라 캐패시터는 급속 충방전이 가능하고 에너지 효율이 높을 뿐 아니라, 화학반응을 이용하는 배터리와는 달리 전해질의 계면에 형성되는 전기 이온층에 전하를 저장하는 방식을 사용하기 때문에 열화현상으로 인한 사이클 수명의 제한이 없으므로 반영구적 수명을 가진다. 또한, 작동 온도가 넓고, 환경 친화적이며, 극성이 바뀌어도 파괴되지 않는 안정적인 제품이기 때문에 그 활용이 점차 확대되고 있다. Therefore, ultracapacitors are not only capable of rapid charge and discharge and high energy efficiency, but also use a method of storing electric charges in an electric ion layer formed at the interface of an electrolyte, unlike a battery using a chemical reaction. Since there is no limit, it has a semi-permanent lifespan. In addition, its utilization is being gradually expanded because it is a stable product which has a wide operating temperature, is environmentally friendly, and which is not destroyed even when the polarity is changed.

이로써 전동차가 역사충전베이(110)에 정차하거나 충전섹션(120)을 통과하는 때에는 정류평활부(220)로부터 공급되는 직류전원이 전력변환부(240)를 통해 전동기(250)를 동작하여 전동차가 운행함과 동시에, 충전부(230)에서는 충전 동작을 수행하게 된다. 이때, 충전 동작의 수행 시 전력은 버퍼용 캐패시터(232)를 통과하여 배터리(231)에 저장되게 된다. Thus, when the electric vehicle stops in the stationary charging bay 110 or passes through the charging section 120, the DC power supplied from the rectification smoothing unit 220 operates the electric motor 250 through the power conversion unit 240 so that the electric vehicle is operated. Simultaneously with operation, the charging unit 230 performs a charging operation. At this time, the power is stored in the battery 231 through the buffer capacitor 232 when performing the charging operation.

또한, 전동차가 충전섹션(120)이 설치되지 않은 노선을 통과하는 때에는 배터리(231)에 저장된 전력이 버퍼용 캐패시터(232)를 통해 방전되어 전력변환부(240)로 전달되고, 이 전력이 전동기(250)를 동작시켜 전동차가 정상적으로 운행 된다.In addition, when the electric vehicle passes through the line where the charging section 120 is not installed, the electric power stored in the battery 231 is discharged through the buffer capacitor 232 and transferred to the power converter 240, and the electric power is transmitted to the electric motor. By operating the 250, the electric vehicle operates normally.

따라서 충전 시간과 방전 시간의 단축을 전력은 버퍼용 캐패시터(232)를 통과하게 되므로, 이때 배터리(231)와 버퍼용 캐패시터(232) 사이에 에너지의 흐름이 바뀌기 때문에 동작을 원활하게 하기 위한 양방향 DC/DC 컨버터(234)가 구비된다. Therefore, since the power passes through the buffer capacitor 232 to shorten the charging time and the discharge time, the bidirectional DC for smooth operation because energy flow is changed between the battery 231 and the buffer capacitor 232 at this time. / DC converter 234 is provided.

이러한 충전부(230)의 모든 충방전 동작은 EMS 컨트롤러(233)에 의해 제어된다. 또한, 상기 EMS 컨트롤러(233)는 차량감지수단(140)과 전력공급제어수단(150)을 컨트롤하는 전력제어장치(130)와 연동되므로, 전동차가 충전을 필요로 하지 않는 경우에는 역사충전베이(110)나 충전섹션(120)을 통과하더라도 불필요한 충전으로 전력이 낭비되고 배터리의 수명이 감소하는 것을 방지할 수 있다.All charging and discharging operations of the charging unit 230 are controlled by the EMS controller 233. In addition, since the EMS controller 233 is interlocked with the power control device 130 for controlling the vehicle detecting means 140 and the power supply control means 150, when the electric vehicle does not require charging, the history charging bay ( Even if it passes through the 110 or the charging section 120, it is possible to prevent unnecessary waste of power and waste of the battery.

또한, 급전선로에 유도전력 방식을 채용하여 급전선을 제거함으로써, 물리적 접촉으로 인한 전력 손실과 사고 위험을 제거할 뿐만 아니라 환경 및 미관적 측면에도 장점을 가진다.In addition, by eliminating the feeder by adopting the induction power system to the feeder line, it not only eliminates power loss and accident risk due to physical contact, but also has advantages in terms of environment and aesthetics.

또한, 충전부에 충전 및 방전시간의 단축을 위한 버퍼용 캐패시터를 구비하여 충전설비의 크기와 용량을 줄임으로써, 동작에 필요한 시간을 감소시켜 급전의 효율을 최대화하는 효과가 있다.In addition, the charging unit includes a buffer capacitor for shortening the charging and discharging time, thereby reducing the size and capacity of the charging facility, thereby reducing the time required for operation and maximizing the efficiency of feeding.
