Description

전압 안정화 모듈이 구비된 철도 무선 급전장치{WIRELESS POWER TRANSMISSION APPARATUS WITH A VOLTAGE STABILIZER MODULE FOR RAILWAY VEHICLE}TECHNICAL FIELD [0001] The present invention relates to a railroad wireless power supply apparatus having a voltage stabilization module,

본 발명은 전압 안정화 모듈이 구비된 철도 무선 급전장치에 관한 것으로, 보다 상세하게 차상 설비부의 전력저장부에 추가로, 전압 안정화 모듈을 연계되게 구비하여 에어갭으로 인한 전압 변동을 방지하고, 회생 제동과 연동하여 전력 발생부에 대한 추가 저장이 이루어지게 함으로써 급전선로의 길이가 짧아질 수 있도록 한 전압 안정화 모듈이 구비된 철도 무선 급전장치에 관한 것이다.More particularly, the present invention relates to a railway wireless power feeding device provided with a voltage stabilization module, and more particularly, to a power supply unit of a vehicle equipped with a voltage stabilization module to prevent voltage fluctuation due to an air gap, And a voltage stabilizing module for shortening the length of the feeder line by making additional storage of the power generating unit in cooperation with the railroad feeder.

주지된 바와 같이, 철도차량에 의한 수송 의존도가 높아짐에 따라 날이 갈수록 철도차량의 수송 수요가 증가하고 있으며, 증가하는 수송 수요를 충족하기 위해서는 철도차량의 운행속도를 증가시킴과 동시에 운행횟수를 증가시켜야만 한다.As is well known, the demand for transportation of railway vehicles is increasing with the increasing dependence on the transportation by the railway vehicle. In order to meet the increasing transportation demand, the traveling speed of the railway vehicle is increased, .

이와 더불어, 교통수단을 이용하는 수요자들은 더욱더 빠른 교통수단을 요구하고 있고, 이에 따른 운행 속도의 향상은 고객에 대한 서비스의 향상으로 인식됨에 따라 다른 교통수단과의 서비스(속도) 경쟁에서 뒤떨어지지 않기 위해서도 필연적으로 철도차량의 운행속도를 향상시킬 필요가 있다.In addition, consumers who use transportation need more and more rapid transportation, and as a result, the improvement of the service speed is perceived as an improvement of the service to the customer, so that it does not fall behind in the service (speed) Inevitably, it is necessary to improve the running speed of the railway vehicle.

한편, 종래의 철도차량 급전시스템의 경우, 급전장치와 집전장치의 물리적 접촉이 전제되기 때문에 장기적으로 보았을 때 유지보수에 드는 시간과 비용이 상당할 수 있다.On the other hand, in the case of the conventional railway vehicle feed system, since the physical contact between the feeder and the current collector is assumed, time and cost for maintenance can be considerable in the long term.

이와 같은 문제점을 해결하고자 비접촉 방식에 의한 급전시스템, 즉 무선급전시스템이 개발되었다. 무선급전시스템은 철도차량 측에 제공되는 집전장치와 선로 상에 제공되는 급전장치 사이에 일정 크기의 공극, 즉 에어갭(air gap)을 두고 공진 방식으로 자기장을 유도하여 철도차량 측에 전력을 공급하는 것을 말한다.In order to solve such a problem, a non-contact type power supply system, that is, a wireless power supply system has been developed. In the wireless power supply system, a magnetic field is induced by a resonance method with a gap of a certain size, that is, an air gap, between a current collector provided on the railway vehicle side and a power feeder provided on the railway, .

더 나아가, 최근에는 철도차량에 전력을 효율적으로 공급하기 위하여, 급전장치를 선로 상에 연속적으로 제공하는 것이 아니라, 선로 상에 단속적인 복수의 급전 세그먼트를 배치하고 있다. 즉, 복수의 급전 세그먼트는 선로 상에 철도차량의 주행 방향을 따라 제공되되, 서로 일정 간격 이격된다. 이러한 복수의 급전 세그먼트 각각에 전력을 공급하고, 복수의 급전 세그먼트 각각에 공급된 전력이 철도차량에 유도되는 것이다.Furthermore, in recent years, in order to efficiently supply electric power to a railway vehicle, a plurality of intermittent power supply segments are disposed on the line, rather than continuously supplying the power supply device on the line. That is, the plurality of power supply segments are provided along the running direction of the railway car on the track, and are spaced apart from each other by a certain distance. Power is supplied to each of the plurality of power supply segments, and power supplied to each of the plurality of power supply segments is induced in the railroad car.

도 1은 종래의 실시예에 따른 철도 무선 급전장치의 구성을 도시한 블록도이다.1 is a block diagram showing a configuration of a railway wireless power feeding apparatus according to a conventional example.

이를 참조하면, 종래의 실시예에 따른 철도 무선 급전장치(2)는 지상에 설치되어 전력을 공급하는 지상 설비부(4)와, 철도 차량상에 설치되어 차량에 추진력을 발생시키기 위해 상기 지상 설비부(4)로부터 전력을 공급받는 차상 설비부(20)로 이루어진다.Referring to FIG. 1, a railway wireless power feeding device 2 according to a related art includes a ground equipment 4 installed on the ground to supply electric power, a ground equipment 4 installed on the railway vehicle, And an on-board equipment part 20 supplied with power from the on-board equipment part 4.

The inverter 8 applies the converted AC power to the feed line 10 installed on the line can do.

급전선로(10)는 급전코어(미도시) 및 급전코어에 수용되는 급전코일(12)을 포함한다. 인버터(8)로부터 공급받은 교류전력에 의해 급전코일(12)에는 전류가 흐르게 되고, 이러한 전류에 의해 급전선로(10)의 주변, 더 구체적으로는 급전선로(10)와 차상 설비부(20) 사이의 에어갭에는 차상 설비부(20) 방향으로의 자기장이 형성되고, 이러한 자기장에 의하여 급전선로(10)에 공급된 교류전력이 차상으로 유도되게 된다.The feeding line 10 includes a feeding core (not shown) and a feeding coil 12 accommodated in the feeding core. Current is supplied to the power supply coil 12 by the AC power supplied from the inverter 8 and the current is supplied to the periphery of the feed line 10 and more specifically between the feed line 10 and the secondary equipment 20 A magnetic field in the direction of the on-board equipment part 20 is formed in the air gap of the power supply line 10, and the AC power supplied to the feed line 10 is induced in the vehicle by the magnetic field.

상기 차상 설비부(20)는 철도차량 측에 제공되는 바, 상기 차상 설비부(20)는 픽업코일(24)을 포함한 픽업모듈(22)이 구성된다. 그 픽업모듈(22)은 상기 급전코일(12)에 유기된 교류전력을 차상으로 집전하는 구성으로, 급전코일(12)로부터 유도된 교류전력이 픽업코일(24)에 흐르게 된다.The on-board equipment part 20 is provided on the railway vehicle side, and the on-board equipment part 20 is constituted by a pickup module 22 including a pickup coil 24. The pick-up module 22 is configured to collect alternating-current power induced in the power-feeding coil 12 in the form of a current, so that alternating-current power derived from the power-feeding coil 12 flows to the pickup coil 24.

이때, 상기 픽업코일(24)에 공급된 교류전력은 바로 철도차량의 추진부(28)로 공급되는 것이 아니라, 레귤레이터(26)를 거치는 바, 레귤레이터(26)는 픽업코일(24)에 공급된 교류전력을 철도차량의 운전에 알맞은 직류전력으로 변환한 후 변환된 직류전력을 차량 추진부(28)로 공급되어 그 차량 추친부(28)에 구성된 공지의 전력 저장부(30)에 전력을 저장하고, 그 전력 저장부(30)에 저장된 전력을 VVVF(32)를 거쳐서 추진력을 발생시키는 모터(34)로 제공하게 된다.The AC power supplied to the pick-up coil 24 is not directly supplied to the propulsion unit 28 of the railway vehicle but passes through the regulator 26. The regulator 26 is supplied to the pickup coil 24 Converts the AC power into DC power suitable for operation of the railway vehicle and then supplies the converted DC power to the vehicle propulsion unit 28 to store power in a known power storage unit 30 configured in the vehicle power unit 28 And supplies the power stored in the power storage unit 30 to the motor 34 that generates the propulsion force via the VVVF 32. [

그러나, 상기한 구성으로 이루어진 종래의 실시예에 따른 철도 무선 급전장치(2)는 상기 급전코일(12)과, 픽업코일(24)간의 에어갭으로 인해 전력 유도시 전압이 불안정해지는 경우가 있다는 문제가 있었다.However, in the railway wireless power feeding device 2 according to the above-described conventional example, the voltage is unstable due to the air gap between the power feeding coil 12 and the pickup coil 24 .

또한, 종래의 실시예에 따른 철도 무선 급전장치(2)는 급전으로 인해 전력저장부(30)가 충전되면 추가로 회생 제동 등을 통한 발전 전력을 저장할 수 없다는 문제가 있었다. 이는 결과적으로 기존에 설치된 급전선로의 길이를 더 줄일 수 없게 되므로 경제적으로 불리하다는 문제가 있었다.In addition, the railroad wireless power supply apparatus 2 according to the related art has a problem that when the power storage unit 30 is charged due to the power supply, the generated power through the regenerative braking or the like can not be further stored. As a result, the length of the existing feeder line can not be further reduced, which is economically disadvantageous.
