Description

本発明は、鉄道車両の駆動制御装置に関し、特に発電手段と電力蓄積手段を備え、この両手段の発生する電力を利用して鉄道車両を駆動する制御装置に関する。   The present invention relates to a drive control device for a railway vehicle, and more particularly to a control device that includes a power generation means and a power storage means, and drives the railway vehicle using electric power generated by both means.

運行本数の少ない地方の鉄道路線では非電化路線が多く、ディーゼルエンジンを動力とする気動車による旅客輸送が一般的である。近年では、エンジンにより駆動する発電設備に、電力蓄電手段を併用して、メンテナンスを抑制し、さらに排気ガスの減少効果も期待できる、いわゆるハイブリッド鉄道車両が開発され、非電化路線への適用も考えられている。   There are many non-electrified routes on local railway lines with a small number of operations, and passenger transportation by diesel powered by diesel engines is common. In recent years, so-called hybrid railway vehicles have been developed, which can reduce power consumption by using power storage means in combination with power generation equipment driven by an engine, and can also be expected to reduce exhaust gas. It has been.

例えば、特許文献１には、ハイブリッド鉄道車両が記載されている。
図５は、ハイブリッド鉄道車両の構成例を示す図である。車両２０１には、エンジンにより駆動され交流電力を発生する発電手段２０２と、この交流電力を直流電力に変換し、さらに電動機に直結された車輪２０６を駆動するため再度交流電力に変換する電力変換手段２０５と、電力変換手段２０５の直流電力を充電及び放電する機能を持つ電力蓄積手段２０４が備えられている。これらの発電手段２０２、電力変換手段２０５、電力蓄積手段２０４は、制御手段２０３によって、最適な電力の管理が行われている。 For example, Patent Document 1 describes a hybrid railway vehicle.
FIG. 5 is a diagram illustrating a configuration example of a hybrid railway vehicle. The vehicle 201 includes a power generation unit 202 that is driven by an engine and generates AC power, and a power conversion unit that converts the AC power into DC power and converts the AC power into AC power again to drive the wheels 206 directly connected to the motor. 205 and a power storage unit 204 having a function of charging and discharging DC power of the power conversion unit 205. The power generation means 202, power conversion means 205, and power storage means 204 are optimally managed by the control means 203.

鉄道車両は、当然寒冷地においても使用されるが、電力蓄電手段に電池を用いると、低温状態では電池の内部抵抗が増加し、放電可能な出力が低下してしまう性質がある。そこで、低温時には発電手段２０２と電力変換手段２０５とを動作させて、暖気運転を行い電池の昇温を図る方法が考えられている。   The railcar is naturally used even in a cold region, but if a battery is used as the power storage means, the internal resistance of the battery increases at a low temperature, and the dischargeable output decreases. In view of this, a method has been considered in which the power generation means 202 and the power conversion means 205 are operated at a low temperature to perform a warm-up operation to increase the temperature of the battery.

しかしながら、発電手段２０２と電力変換手段２０５の両手段とも動作させると、交流電力を直流電力に変換する手段と、直流電力を交流電力に変換する手段の間で、主な電力のやり取りが行われ、車両の運転に必要な電力の供給が不足する状態が発生するなど、暖機運転が車両の運転状況を制約するという問題点があった。
特開２００５−２７４４７号公報 However, when both the power generation means 202 and the power conversion means 205 are operated, main power is exchanged between the means for converting AC power into DC power and the means for converting DC power into AC power. There is a problem that the warm-up operation restricts the driving state of the vehicle, such as a state where the supply of electric power necessary for driving the vehicle is insufficient.
JP 2005-27447 A

本発明は、上記事情に鑑み、低温時において電力変換手段の動作を最小限にして、省エネルギ効果の大きい鉄道車両の駆動制御装置を提供することを目的とする。   In view of the above circumstances, an object of the present invention is to provide a drive control device for a railway vehicle having a large energy saving effect by minimizing the operation of power conversion means at low temperatures.

本発明は、電源投入時、及び低温時において、電力変換手段の直流電力を交流電力に変換する手段を動作させることなく、エンジンにより駆動される発電手段の交流電力を、直流電力に変換する手段を介して、蓄電手段に充電させる処理と、蓄電手段の放電電力を上記の交流電力を直流電力に変換する手段を介して、発電手段側で負荷吸収する処理とを、１回以上交互に繰り返すことを特徴とする。   The present invention provides means for converting the AC power of the power generation means driven by the engine into DC power without operating the means for converting the DC power of the power conversion means into AC power when the power is turned on and at a low temperature. The process of charging the power storage means via the power supply and the process of absorbing the load on the power generation means side through the means for converting the discharge power of the power storage means to the DC power are alternately repeated one or more times. It is characterized by that.

本発明によれば、インバータを動作させずに、エンジンと発電機を駆動させて蓄電池の充放電処理を行うことで、蓄電池の劣化を抑制ができ、また蓄電池の性能低下に伴う鉄道車両の性能低下も抑制可能で、さらにエンジンと蓄電池双方を同時に暖機運転できる。   According to the present invention, the deterioration of the storage battery can be suppressed by driving the engine and the generator without operating the inverter and performing the charge / discharge process of the storage battery, and the performance of the railway vehicle accompanying the performance deterioration of the storage battery. The decrease can be suppressed, and furthermore, both the engine and the storage battery can be warmed up simultaneously.

以下に、本発明の実施の形態について図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明の実施例１の鉄道車両の駆動制御装置を示す。図１において、エンジン２には発電機３が直結され、エンジン２を駆動することにより発電機３は交流電力を発生する。交流電力はコンバータ４に送られ直流電力に変換される。コンバータ４の出力には蓄電池１とインバータ５が接続され、直流電力を再度交流電力に変換しこの交流電力で電動機６と電動機７を駆動する。   FIG. 1 shows a drive control apparatus for a railway vehicle according to a first embodiment of the present invention. In FIG. 1, a generator 3 is directly connected to the engine 2, and the generator 3 generates AC power by driving the engine 2. The AC power is sent to the converter 4 and converted into DC power. The storage battery 1 and the inverter 5 are connected to the output of the converter 4, and the DC power is again converted into AC power, and the motor 6 and the motor 7 are driven by this AC power.

エンジン２、コンバータ４、蓄電池１、インバータ５のそれぞれは、エンジン制御装置４２、コンバータ制御装置４３、蓄電池制御装置１１、インバータ制御装置４４によって、出力電力の制御が行われるが、これらの制御装置は統括制御装置８によって適正な電力管理が実施される。また、これらの制御装置周辺の温度を検出する温度検出器２１の出力２２も統括制御装置８に入力される。   Each of the engine 2, the converter 4, the storage battery 1, and the inverter 5 is controlled in output power by the engine control device 42, the converter control device 43, the storage battery control device 11, and the inverter control device 44. Appropriate power management is performed by the overall control device 8. The output 22 of the temperature detector 21 that detects the temperature around these control devices is also input to the overall control device 8.

図１に示す構成の駆動制御装置を備えた鉄道車両は、いわゆるハイブリッド型鉄道車両と呼ばれ、蓄電池１は蓄電池１自身の放電可能電力や車両の走行条件による充電や放電を統括制御装置８によって管理されるが、例えば周囲温度が低い場合には、蓄電池１の内部抵抗が増加して、蓄電池１の持っている性能の最大電流を充放電に使用できないという不具合が発生し、蓄電池１の性能の劣化や、ひいては低温時のハイブリッド型鉄道車両の性能低下にもなってしまう怖れがある。   The railway vehicle provided with the drive control device having the configuration shown in FIG. 1 is called a so-called hybrid railway vehicle, and the storage battery 1 is charged by the storage battery 1 itself with dischargeable power and charging and discharging according to the running conditions of the vehicle by the overall control device 8. However, when the ambient temperature is low, for example, the internal resistance of the storage battery 1 increases, and the malfunction that the maximum current of the performance of the storage battery 1 cannot be used for charging / discharging occurs. There is a fear that it may deteriorate, and as a result, the performance of the hybrid railway vehicle at a low temperature may deteriorate.

そこで、低温時には暖機運転を採用することになるが、エンジン、発電機、コンバータ、インバータを全て動作させて蓄電池の充放電処理を行うことは、前述したように暖機運転が車両の運転状況を制約することから、有効な手段とはいえない。   Therefore, warm-up operation is adopted at low temperatures, but the charging / discharging process of the storage battery by operating all of the engine, generator, converter, and inverter is performed as described above. Therefore, it is not an effective means.

以下、本発明の実施例１の駆動制御装置の動作を図２の動作フローチャートを用いて説明する。本発明の実施例１では、インバータを動作させることなく、エンジンと発電機とコンバータの動作により、エンジン発電による蓄電池への充電と、蓄電池放電により発電機を駆動しエンジンブレーキでの負荷吸収とを繰り返すことで蓄電池の温度上昇を促進するものである。   The operation of the drive control apparatus according to the first embodiment of the present invention will be described below with reference to the operation flowchart of FIG. In the first embodiment of the present invention, the operation of the engine, the generator, and the converter without operating the inverter allows the storage battery to be charged by engine power generation, and the generator is driven by the storage battery discharge to absorb the load at the engine brake. By repeating, the temperature rise of the storage battery is promoted.

すなわち、運転日の最初の電源投入では充放電の繰り返し処理を行う（１０１）。最初の電源投入でない時でも、周囲温度２２や蓄電池１の温度を測定し（１０２）、その値が設定値以下の場合でも充放電の繰り返し処理を行う（１０３）。充放電の繰り返し処理の先頭で蓄電池１の温度を測定する（１０４）。蓄電池１の温度が充分に上昇しているならば充放電の繰り返し処理を終了する（１１１）が、最初の電源投入時や周囲温度２２が低ければ、蓄電池１の温度も設定値以下のため、１回目の充電処理の判定を行い（１０６）、１回目の充電処理を行い（１０７）、その後充放電の繰り返し処理の先頭１０４へ戻る。   That is, when the power is turned on for the first time on the operation day, charge / discharge is repeatedly performed (101). Even when the power is not turned on for the first time, the ambient temperature 22 and the temperature of the storage battery 1 are measured (102), and even when the value is equal to or less than the set value, the charge / discharge process is repeated (103). The temperature of the storage battery 1 is measured at the head of the repeated charging / discharging process (104). If the temperature of the storage battery 1 has risen sufficiently, the charging / discharging process is terminated (111). However, when the power is turned on for the first time or the ambient temperature 22 is low, the temperature of the storage battery 1 is also below the set value. The first charging process is determined (106), the first charging process is performed (107), and then the process returns to the top 104 of the charge / discharge repetition process.

ここで、再度蓄電池１の温度を測定し、蓄電池１の温度が設定値以下であれば、１回目の充電処理は終了しているので、電池の残容量ＳＯＣを測定し（１０８）、残容量ＳＯＣが基準値以上であれば、蓄電池１の放電処理（１０９）を行い、残容量ＳＯＣが基準値以下であれば蓄電池１の充電処理を行うように動作させる（１１０）。その後、充放電の繰り返し処理の先頭に戻る（１０４）。   Here, the temperature of the storage battery 1 is measured again. If the temperature of the storage battery 1 is equal to or lower than the set value, the first charging process is completed, so the remaining capacity SOC of the battery is measured (108), and the remaining capacity is determined. If the SOC is equal to or higher than the reference value, the storage battery 1 is discharged (109), and if the remaining capacity SOC is equal to or lower than the reference value, the storage battery 1 is charged (110). Thereafter, the process returns to the beginning of the repeated charge / discharge process (104).

以降は蓄電池１の温度が設定値以上になるまで、１０４→１０５→１０６→１０８の処理を行い、その後は条件によって１０９または１１０の処理を繰り返す。   Thereafter, the process of 104 → 105 → 106 → 108 is performed until the temperature of the storage battery 1 becomes equal to or higher than the set value, and thereafter the process of 109 or 110 is repeated depending on conditions.

図３、図４は上記の蓄電池１への充放電処理での電力の流れを説明する図であり、図３は充電処理、図４は放電処理を示す。すなわち、図３の充電処理では、エンジン２を起動し、発電機３で発生させた交流電力１５１を、コンバータ４を介して直流電力１５２に変換し、蓄電池１への充電を行う。   3 and 4 are diagrams for explaining the flow of power in the charge / discharge process for the storage battery 1, FIG. 3 shows the charge process, and FIG. 4 shows the discharge process. That is, in the charging process of FIG. 3, the engine 2 is started, AC power 151 generated by the generator 3 is converted into DC power 152 through the converter 4, and the storage battery 1 is charged.

図４の放電処理では、蓄電池１からの放電電力１６２を、コンバータ４を介して交流電力１６１へ逆変換し、発電機３を駆動してエンジンブレーキによる負荷吸収を行わせる。   In the discharge process of FIG. 4, the discharge power 162 from the storage battery 1 is reversely converted to the AC power 161 via the converter 4, and the generator 3 is driven to absorb the load by the engine brake.

このように、本発明の実施例１では、インバータを駆動させることなく、蓄電池の充放電処理を行うことが可能となる。また、充放電処理の停止条件を蓄電池温度の設定値で判定しているが、充放電の処理回数で判定してもよい。   Thus, in Example 1 of this invention, it becomes possible to perform the charging / discharging process of a storage battery, without driving an inverter. Moreover, although the stop condition of the charging / discharging process is determined by the set value of the storage battery temperature, it may be determined by the number of charging / discharging processes.

なお、本発明の実施例１では、駆動制御装置のハイブリッド鉄道車両用への適用について説明されているが、インバータを動作させることなくエンジンと発電機とコンバータの動作により、エンジン発電による蓄電池への充電と蓄電池放電により発電機を駆動しエンジンブレーキでの負荷吸収とを繰り返すことで蓄電池の温度上昇を促進する技術を、鉄道車両に限らず、寒冷地での車両の暖機運転にも適用することが可能である。   In the first embodiment of the present invention, the application of the drive control device to the hybrid railway vehicle is described. However, the operation of the engine, the generator, and the converter without operating the inverter allows the storage to the storage battery by the engine power generation. The technology that promotes the temperature rise of the storage battery by driving the generator by charging and discharging the storage battery and absorbing the load by the engine brake is applied not only to railway vehicles but also to warming up the vehicle in cold regions It is possible.
