Description

移動体の蓄電装置管理装置及びその方法Storage device management apparatus and method for mobile body
　本発明は、鉄道車両等の移動体に搭載される蓄電装置を管理する移動体の蓄電装置管理装置及びその方法に関する。 The present invention relates to a power storage device management apparatus for a mobile body that manages a power storage device mounted on a mobile body such as a railway vehicle, and a method thereof.
　近年、原動機などで走行する鉄道車両の低燃費化を実現するために、蓄電装置を搭載し、減速エネルギの回収および加速時の駆動エネルギのアシストを行う鉄道車両が開発されている。これらの鉄道車両に搭載された蓄電装置は、使用環境に応じ経年劣化していくことが知られている。経年劣化が進行すると、蓄電装置を利用した制御が充分に機能せず、本来の走行性能を発揮出来なくなる。そのため、劣化がある程度進行した段階で蓄電装置を交換するのが一般的である。蓄電装置の交換作業は数日かかるため、交換作業中は数日運行を停止する必要がある。運行停止による経済損失は大きく、蓄電池交換作業による運行停止は鉄道事業者にとって大きな課題である。 In recent years, in order to realize low fuel consumption of a railway vehicle that is driven by a prime mover or the like, a railway vehicle that is equipped with a power storage device and collects deceleration energy and assists driving energy during acceleration has been developed. It is known that power storage devices mounted on these railway vehicles deteriorate over time according to the usage environment. As the aging progresses, the control using the power storage device does not sufficiently function, and the original traveling performance cannot be exhibited. Therefore, it is common to replace the power storage device when the deterioration has progressed to some extent. Since the replacement work of the power storage device takes several days, it is necessary to stop the operation for several days during the replacement work. Economic loss due to operation suspension is large, and operation suspension due to battery replacement work is a major issue for railway operators.
　この課題を解決する手段として、蓄電装置の交換作業を、数年に一度の定期検査に合わせて行うことが挙げられる。鉄道車両は定期検査を行う際、全ての部品を点検するため、数日間運行を停止する。そのため、この期間内に蓄電装置を交換することで、運行停止による経済損失を最低限に抑えることができる。しかし、定期検査の時期まで劣化状態を維持する方策を考え、実行することは非常に困難である。蓄電装置の劣化速度は、使用状況に応じて変化するためである。 As a means for solving this problem, it is possible to replace the power storage device in accordance with a periodic inspection once every several years. Railroad cars stop operating for several days in order to inspect all parts during periodic inspections. Therefore, by replacing the power storage device within this period, economic loss due to operation stop can be minimized. However, it is very difficult to consider and implement measures to maintain the deterioration state until the period of regular inspection. This is because the deterioration rate of the power storage device changes according to the use situation.
　これに対し、特許文献１には、時間経過に基づいた蓄電装置の劣化状態を基準劣化パターンとして予め設定しておき、車両がこれから走るルートに関する情報から推定したルート走破後の蓄電装置の劣化状態推定値が、設定した基準劣化パターンよりも悪くなることが予想された場合、蓄電装置の劣化速度を遅くするために充放電電力を制限する技術が開示されている。 On the other hand, in Patent Document 1, the deterioration state of the power storage device based on the passage of time is set in advance as a reference deterioration pattern, and the deterioration state of the power storage device after the route running estimated from information on the route on which the vehicle will run will be described. A technique is disclosed that limits charge / discharge power in order to reduce the deterioration rate of the power storage device when the estimated value is predicted to be worse than the set reference deterioration pattern.

　特許文献１に記載の従来技術において、基準劣化パターンは、蓄電装置の劣化状態を交換時期まで最低限維持できるパターンとして、時間経過に対して運行に関係なく設定されている。しかしながら、実際の鉄道車両の運行においては、時間経過に対して運行に関係なく劣化が進行することはなく、運行毎に劣化速度が異なる。このため、充放電電力が大きく基準劣化パターンよりも劣化速度が速い運行で特許文献１の制御を用いた場合、時間経過に対して一定の速度で劣化が進行する基準劣化パターンに追従するようにするために充放電電力を制限することが行われ、本来の走行性能を発揮できない可能性がある。 In the prior art described in Patent Document 1, the reference deterioration pattern is set as a pattern that can maintain the deterioration state of the power storage device at the minimum until the replacement time, regardless of the operation over time. However, in actual railway vehicle operation, deterioration does not progress regardless of operation over time, and the deterioration rate differs for each operation. For this reason, when the control of Patent Document 1 is used in operation where the charge / discharge power is large and the deterioration rate is faster than the reference deterioration pattern, it follows the reference deterioration pattern in which deterioration proceeds at a constant speed over time. Therefore, there is a possibility that the charge / discharge power is limited, and the original running performance cannot be exhibited.
　本発明は、蓄電装置の劣化状態を交換時期まで基準値を超える値に維持するための基準劣化パターンの組み合わせを移動体の運行に応じて設定することを目的とする。 An object of the present invention is to set a combination of reference deterioration patterns for maintaining the deterioration state of the power storage device at a value exceeding the reference value until the replacement time according to the operation of the moving body.
　前記課題を解決するために、本発明は、移動体に搭載された蓄電装置の劣化状態を推定し、前記蓄電装置の劣化状態を推定した劣化推定日時と当該劣化推定日時における前記蓄電装置の劣化状態推定値を含む蓄電装置劣化状態情報を出力する劣化状態推定手段と、前記移動体に割当てられる１つの運行で運転した場合の前記蓄電装置の劣化状態低下量の時間的変化を示すパターンであって、少なくとも１つ以上の劣化速度設定値と前記１つの運行に要する時間とから設定される基準劣化パターンを、前記移動体に割当てられる１つ以上の組み合わせの運行に対応づけて当該運行毎に計算して管理する基準劣化パターン計算手段と、前記基準劣化パターン計算手段の出力を基に前記蓄電装置の劣化状態を判定する劣化状態判定手段と、を備えることを特徴とする。 In order to solve the above-described problem, the present invention estimates a deterioration state of a power storage device mounted on a mobile body, a deterioration estimation date / time when the deterioration state of the power storage device is estimated, and deterioration of the power storage device at the deterioration estimation date / time. It is a pattern showing deterioration state estimation means for outputting power storage device deterioration state information including a state estimation value, and a temporal change of the deterioration state decrease amount of the power storage device when operated by one operation assigned to the moving body. The reference deterioration pattern set from at least one deterioration speed setting value and the time required for one operation is associated with one or more combinations of operations assigned to the mobile body for each operation. Reference deterioration pattern calculation means for calculating and managing, and deterioration state determination means for determining the deterioration state of the power storage device based on the output of the reference deterioration pattern calculation means. It is characterized in.

Specifically, when the operation of “1” (“operation 1”) is specified in the assigned operation 153a, the information “0.02” is recorded in the normal deterioration rate setting value 153b.

It may be output.
　蓄電装置交換計画設定手段１０６は、蓄電装置１０１の交換時期を示す蓄電装置交換日時１５６を基準劣化パターン計算手段１０７へ出力し、蓄電装置１０１の交換が必要であると判定するための基準値となる蓄電装置交換基準値１６６を基準劣化パターン再計算判定手段１０８へ出力する。蓄電装置交換日時１５６としては、定期検査が開始される日時を設定することが望ましいが、鉄道車両の管理者が、蓄電装置１０１を交換するのに最も適していると判断した日時が他にあれば、その日時としてもかまわない。蓄電装置交換基準値１６６としては、蓄電装置１０１の容量維持率や内部抵抗増加率で示すのが一般的であるが、必ずしもそれに限ったものではない。 The power storage device replacement plan setting means 106 outputs a power storage device replacement date and time 156 indicating the replacement time of the power storage device 101 to the reference deterioration pattern calculation means 107, and a reference value for determining that the power storage device 101 needs to be replaced. The power storage device replacement reference value 166 is output to the reference deterioration pattern recalculation determination means 108. As the power storage device replacement date and time 156, it is desirable to set the date and time when the periodic inspection is started, but there are other dates and times that the manager of the railway vehicle determines to be most suitable for replacing the power storage device 101. For example, the date may be used. The power storage device replacement reference value 166 is generally indicated by the capacity maintenance rate or the internal resistance increase rate of the power storage device 101, but is not necessarily limited thereto.

　基準劣化パターン再計算判定手段１０８は、基準劣化パターン計算手段１０５から出力された基準劣化パターン暫定値１５７と、蓄電装置交換計画設定手段１０６から出力された蓄電装置交換基準値１６６をそれぞれ入力し、各入力した値を基に鉄道車両に割当てられた運行で蓄電装置１０１を運転した場合に、蓄電装置１０１の交換日時（蓄電装置交換日時１５６）まで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を超える値（状態）に維持することができるか否かを判断する。基準劣化パターン再計算判定手段１０８は、維持できないと判断した場合、基準劣化パターン計算手段１０７へ、再計算指令１７８と劣化速度選択情報１６８を出力し、維持できると判断した場合、電力制御手段１０９へ基準劣化パターン確定値１５８を出力する。再計算指令１７８は、通常時（基準劣化パターン再計算判定手段１０８が蓄電装置１０１の交換日時まで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を超える値に維持できると判断した場合）は、OFFの情報として出力されるが、基準劣化パターン再計算判定手段１０８が蓄電装置１０１の交換日時まで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を超える値に維持できないと判断した場合、ONの情報として出力される。基準劣化パターン再計算判定手段１０８の処理の詳細については後述する。 The reference deterioration pattern recalculation determination unit 108 inputs the reference deterioration pattern provisional value 157 output from the reference deterioration pattern calculation unit 105 and the power storage device replacement reference value 166 output from the power storage device replacement plan setting unit 106, respectively. When the power storage device 101 is operated in an operation assigned to the railway vehicle based on each input value, the deterioration state of the power storage device 101 is replaced with the power storage device replacement until the power storage device 101 replacement date (power storage device replacement date 156). It is determined whether or not the value (state) exceeding the reference value 166 can be maintained.

[基準劣化パターン計算手段１０７]
　図５は、基準劣化パターン計算手段１０７の内部処理（予測演算処理）を示したものである。この処理は、ＣＰＵが、メモリから読み出した基準劣化パターン計算プログラムを実行することにより開始される。まず、基準劣化パターン計算手段１０７は、計算開始指令手段１０５の出力を取り込み、計算開始指令がONか否かを判定し（ステップ５０１）、計算開始指令１５５がONである場合にはステップ５０４へ進み、計算開始指令１５５がOFFである場合にはステップ５０２へ進む。ステップ５０２では、基準劣化パターン計算手段１０７は、基準劣化パターン再計算判定手段１０８の出力を取り込み、再計算指令がONか否かを判定し、再計算指令１７８がONである場合にはステップ５０３へ進み、再計算指令１７８がOFFである場合には、ステップ５０１に戻り、ステップ５０１の処理を繰り返す。 [Standard degradation pattern calculation means 107]
FIG. 5 shows the internal processing (prediction calculation processing) of the reference deterioration pattern calculation means 107. This process is started when the CPU executes the reference deterioration pattern calculation program read from the memory. First, the reference deterioration pattern calculation unit 107 takes in the output of the calculation start command unit 105 and determines whether or not the calculation start command is ON (step 501). If the calculation start command 155 is ON, the process proceeds to step 504. If the calculation start command 155 is OFF, the process proceeds to step 502. In step 502, the reference deterioration pattern calculation means 107 takes in the output of the reference deterioration pattern recalculation determination means 108, determines whether or not the recalculation instruction is ON, and if the recalculation instruction 178 is ON, step 503 If the recalculation command 178 is OFF, the process returns to step 501 and the process of step 501 is repeated.
　ステップ５０３では、基準劣化パターン計算手段１０７は、基準劣化パターン再計算判定手段１０８の出力による劣化速度選択情報１６８を基に、基準劣化パターンの計算に用いる劣化速度設定値を運行毎に設定する。劣化速度選択情報１６８は、割当てられた運行毎に、基準劣化パターンの計算に用いる劣化速度設定値を設定したものである。図６は、劣化速度選択情報１６８の例を示す構成図である。図６において、劣化速度選択情報１６８は、割当てられた運行１６８ａと、計算に用いる劣化速度設定値１６８ｂから構成される。割当てられた運行１６８ａには、割当てられた運行１５３ａと同様に、鉄道車両に割当てられた運行を特定する情報として、「１」、「２」、「３」などの情報が記録される。計算に用いる劣化速度設定値１６８ｂには、通常時の劣化速度を選択する場合の設定値として、「通常用」の情報が記録され、或いは、蓄電装置１０１の劣化状態を維持するための劣化速度を選択する場合の設定値として、「蓄電装置劣化維持用」の情報が記録される。 In step 503, the reference deterioration pattern calculation means 107 sets a deterioration speed setting value used for calculation of the reference deterioration pattern for each operation based on the deterioration speed selection information 168 output from the reference deterioration pattern recalculation determination means 108. The deterioration speed selection information 168 is set with a deterioration speed setting value used for calculating a reference deterioration pattern for each assigned operation. FIG. 6 is a configuration diagram showing an example of the degradation rate selection information 168. As shown in FIG. In FIG. 6, the deterioration speed selection information 168 is composed of an assigned operation 168a and a deterioration speed setting value 168b used for calculation. In the assigned operation 168a, as in the assigned operation 153a, information such as “1”, “2”, “3”, etc. is recorded as information specifying the operation assigned to the railway vehicle. In the deterioration rate setting value 168b used for the calculation, “normal use” information is recorded as a setting value for selecting the normal deterioration rate, or the deterioration rate for maintaining the deterioration state of the power storage device 101. As the setting value when selecting, information for “maintaining power storage device deterioration” is recorded.
　図６の例では、割当てられた運行１６８ａが「１」となる「運行１」と、割当てられた運行１６８ａが「３」となる「運行３」は、通常用（通常用の劣化速度設定値）を用いるが、割当てられた運行１６８ａが「２」となる「運行２」は、蓄電装置劣化維持用（蓄電装置劣化維持用の劣化速度設定値）を用いることを示している。これにより、基準劣化パターン計算手段１０７は、再計算の際（再計算指令１７８がONの場合）には、基準劣化パターン再計算判定手段１０８で設定した劣化速度選択情報１６８に従い、一部の運行の劣化速度設定値を変更した状態（一部の運行の劣化速度設定値を、「通常用」から「蓄電装置劣化維持用」に変更した状態）で基準劣化パターン暫定値１５７を計算することができる。基準劣化パターン計算手段１０７は、ステップ５０３での処理が終了したら、ステップ５０５へ進む。 In the example of FIG. 6, “operation 1” in which the assigned operation 168a is “1” and “operation 3” in which the assigned operation 168a is “3” are normal (deterioration speed setting values for normal use). However, “operation 2” in which the assigned operation 168a is “2” indicates that power storage device deterioration maintenance (deterioration speed setting value for power storage device deterioration maintenance) is used. As a result, the reference deterioration pattern calculation unit 107 performs some operations according to the deterioration speed selection information 168 set by the reference deterioration pattern recalculation determination unit 108 during recalculation (when the recalculation command 178 is ON). The reference deterioration pattern provisional value 157 may be calculated in a state in which the deterioration speed setting value of the vehicle is changed (the deterioration speed setting value of a part of the operation is changed from “for normal use” to “for power storage device deterioration maintenance”). it can. The reference deterioration pattern calculation unit 107 proceeds to step 505 when the processing in step 503 is completed.
　基準劣化パターン計算手段１０７は、ステップ５０１で、計算開始指令がONと判定した場合、劣化速度選択情報を初期化し（ステップ５０４）、割当てられた全ての運行で、基準劣化パターンの計算に用いる劣化速度設定値１６８ｂを「通常用」に設定し、ステップ５０５へ進む。 If it is determined in step 501 that the calculation start command is ON, the reference deterioration pattern calculation unit 107 initializes deterioration speed selection information (step 504), and deterioration used for calculation of the reference deterioration pattern in all assigned operations. The speed set value 168b is set to “normal use” and the process proceeds to step 505.
　基準劣化パターン計算手段１０７は、ステップ５０５では、蓄電装置劣化状態１５２を基に、最新の劣化状態推定日時における劣化状態を起点（基準劣化パターン計算の起点）として設定し、ステップ５０６へ進む。 In step 505, the reference deterioration pattern calculation means 107 sets the deterioration state at the latest deterioration state estimation date and time as a starting point (starting point of reference deterioration pattern calculation) based on the power storage device deterioration state 152, and proceeds to step 506.
　基準劣化パターン計算手段１０７は、ステップ５０６では、図４の運行関連情報１５４を読込み、運行関連情報１５４を基に割当てられた運行と運行日時を設定し、ステップ５０７へ進む。 In step 506, the reference deterioration pattern calculation means 107 reads the operation related information 154 in FIG. 4, sets the operation and operation date / time assigned based on the operation related information 154, and proceeds to step 507.
　基準劣化パターン計算手段１０７は、ステップ５０７では、ステップ５０８、ステップ５０９、ステップ５１０の処理を、鉄道車両に割当てられた運行数分だけ繰り返すループ処理を実施する。 In step 507, the reference deterioration pattern calculation means 107 performs a loop process that repeats the processes of step 508, step 509, and step 510 by the number of operations allocated to the railway vehicle.
　基準劣化パターン計算手段１０７は、ステップ５０８では、図２の劣化速度設定値情報１５３を基に、参照中のループの運行における劣化速度設定値（劣化速度）を参照する。なお、参照中のループの運行における劣化速度選択情報１５３が、「通常用」であれば、参照中のループの運行における劣化速度設定値として、通常用の劣化速度設定値１５３ｂを参照し、「蓄電装置劣化維持用」であれば、参照中のループの運行における劣化速度設定値として、蓄電装置劣化維持用の劣化速度設定値１５３ｃを参照する。 In step 508, the reference deterioration pattern calculation means 107 refers to the deterioration speed setting value (deterioration speed) in the operation of the loop being referred to based on the deterioration speed setting value information 153 of FIG. If the deterioration speed selection information 153 in the loop operation being referred to is “normal”, the deterioration speed setting value 153b for normal use is referred to as the deterioration speed setting value in the operation of the loop being referred to, If it is “for storage device deterioration maintenance”, the deterioration rate setting value 153c for storage device deterioration maintenance is referred to as the deterioration rate setting value in the operation of the loop being referred to.
　基準劣化パターン計算手段１０７は、ステップ５０９では、ステップ５０８で参照した劣化速度設定値１５３ｂ又は１５３ｃを用いて、起点からの劣化状態低下量を求め、起点の日時（劣化状態推定日時）と参照中のループの運行にかかる時間とから、起点から、参照中のループの運行が終了する日時（運行終了日時）まで、運転した場合（蓄電装置１０１を運転した場合）の蓄電装置１０１の劣化状態（劣化状態低下量）を示す基準劣化パターンを計算する。 In step 509, the reference deterioration pattern calculation means 107 obtains the deterioration state decrease amount from the starting point by using the deterioration speed set value 153b or 153c referred to in step 508, and is referring to the starting point date and time (deteriorating state estimation date and time). The deterioration state of the power storage device 101 when it is operated (when the power storage device 101 is operated) from the starting time to the date and time when the reference loop operation ends (operation end date and time) A reference deterioration pattern indicating the amount of deterioration state deterioration) is calculated.
　基準劣化パターン計算手段１０７は、ステップ５１０では、基準劣化パターンの最終的な劣化状態と日時を、次のループにおける起点として設定（再設定）する。この処理によって、次のループの運行における基準劣化パターンを、参照中のループの運行が終了した時点での劣化状態と日時を起点として計算することができるようになる。 In step 510, the reference deterioration pattern calculation means 107 sets (resets) the final deterioration state and date / time of the reference deterioration pattern as the starting point in the next loop. By this processing, the reference deterioration pattern in the next loop operation can be calculated from the deterioration state and the date and time when the reference loop operation ends.
　基準劣化パターン計算手段１０７は、蓄電装置交換計画設定手段１０６の出力による蓄電装置交換日時１５６と、参照中のループの運行が終了する日時（参照中のループの運行にかかる時間から算出される運行終了日時）とを比較し、参照中のループの運行が終了する日時（運行終了日時）が、蓄電装置交換日時１５６を超えているか否かを判定し（ステップ５１１）、運行終了日時が蓄電装置交換日時１５６を超えている場合は、ステップ５１３へ進み、運行終了日時が蓄電装置交換日時１５６を超えていない場合は、再びステップ５０７へ戻り、次のループの処理へ移行する。鉄道車両に割当てられた運行が全て終了した場合は、ループを抜けてステップ５１２へ進む。 The reference deterioration pattern calculation unit 107 calculates the power storage device replacement date and time 156 based on the output of the power storage device replacement plan setting unit 106 and the date and time when the reference loop operation ends (the operation calculated from the time required for the reference loop operation). End date and time), and it is determined whether or not the date and time when the operation of the loop being referred to ends (operation end date and time) exceeds the power storage device replacement date and time 156 (step 511). If the replacement date and time 156 has been exceeded, the process proceeds to step 513. If the operation end date and time has not exceeded the power storage device replacement date and time 156, the process returns to step 507 again, and the process proceeds to the next loop. If all the operations assigned to the railway vehicle have been completed, the process goes out of the loop and proceeds to step 512.
　基準劣化パターン計算手段１０７は、ステップ５１２では、基準劣化パターンの計算終了後から再び同じ運行を繰り返したと仮定して、運行日時を再計算して設定する。すなわち、これまでの基準劣化パターンの計算終了後から、再び同じ運行の組み合わせを繰り返すために、運行日時を再計算する。例えば、割当てられた運行が１０日分あった場合、１１日目から再び同じ運行を繰り返せるように、各運行日時を再計算していく。各運行日時の計算が完了したら、基準劣化パターン計算手段１０７は、再び基準劣化パターン計算ループの処理を実行するために、ステップ５０７へ進み、基準劣化パターンの計算を続ける。 In step 512, the reference deterioration pattern calculation means 107 recalculates and sets the operation date and time assuming that the same operation is repeated again after the calculation of the reference deterioration pattern. That is, after the calculation of the reference deterioration pattern so far, the operation date and time is recalculated in order to repeat the same operation combination again. For example, when there are 10 days of assigned operations, the operation dates and times are recalculated so that the same operation can be repeated again from the 11th day. When the calculation of each operation date / time is completed, the reference deterioration pattern calculation unit 107 proceeds to step 507 to continue the calculation of the reference deterioration pattern in order to execute the reference deterioration pattern calculation loop again.
　ここで、基準劣化パターンの例を図７に示す。図7は、基準劣化パターン計算手段１０７の内部処理を実行した結果、計算される基準劣化パターンの例を示す特性図である。図７には、鉄道車両に３つの運行が割当てられ、同じ運行を２周分実施した段階で蓄電装置交換日時に到達する場合の例が示されている。図７において、横軸は時間であり、縦軸は劣化状態（推定値）である。図７における劣化状態は、最新の劣化状態が、劣化状態７００で、１周目の運行（時間ｔ１～ｔ２）である「運行１」～「運行３」がそれぞれ終了した時点での劣化状態が、劣化状態（劣化状態７００からの低下量を示す劣化状態低下量）７０１～７０３である。また、２周目の運行（時間ｔ２～ｔ４）である「運行１」～「運行３」がそれぞれ終了した時点での劣化状態が劣化状態（劣化状態低下量）７１１～７１３である。まず、最新の劣化状態７００が推定された推定日時（劣化状態推定日時）を示す時間ｔ１と劣化状態７００をそれぞれ起点とし、「運行１」における劣化速度設定値（例えば、通常用劣化速度設定値１５３ｂ）を基に、「運行１」が終了するまでの劣化状態（劣化状態低下量）７０１を示す基準劣化パターン（起点用基準劣化パターン）Ｐ１が作成される。 Here, an example of the reference deterioration pattern is shown in FIG. FIG. 7 is a characteristic diagram showing an example of a reference deterioration pattern calculated as a result of executing the internal processing of the reference deterioration pattern calculation means 107. FIG. 7 shows an example in which three operations are allocated to the railway vehicle and the storage device replacement date and time is reached when the same operation is performed for two laps. In FIG. 7, the horizontal axis represents time, and the vertical axis represents the deterioration state (estimated value). In the deterioration state in FIG. 7, the latest deterioration state is the deterioration state 700, and the deterioration state at the time when “operation 1” to “operation 3”, which are the operations of the first lap (time t1 to t2), are finished. Degradation states (degradation state decrease amounts indicating decrease amounts from the deterioration state 700) 701 to 703. In addition, the deterioration states (deterioration state reduction amounts) 711 to 713 at the time when “operation 1” to “operation 3”, which are the operations in the second round (time t2 to t4), are finished, respectively. First, a deterioration speed setting value for “operation 1” (for example, a normal deterioration speed setting value) is set starting from a time t1 indicating the estimated date and time (deterioration state estimation date and time) when the latest deterioration state 700 is estimated. Based on 153b), a reference deterioration pattern (starting point reference deterioration pattern) P1 indicating a deterioration state (deterioration state decrease amount) 701 until “operation 1” is completed is created.
　「運行２」以降は、１つ前の運行終了日時における劣化状態を起点とし、各運行における劣化速度設定値（例えば、通常用劣化速度設定値１５３ｂ）から各運行が終了するまでの基準劣化パターンＰ２、Ｐ３が作成される。当該車両（鉄道車両）が割当てられた運行（「運行１」～「運行３」）が終了した後（時間ｔ１から時間ｔ２までの運行期間Ｔ１が経過した後）も、「運行３」の終了日時が、蓄電装置交換日時１５６を示す時間ｔ３を超えていない場合、再び同じ運行の組み合わせ（「運行１」～「運行３」）を、時間t２から時間ｔ４までの運行期間Ｔ２に繰り返し、運行終了日時が、蓄電装置交換日時１５６を示す時間ｔ３を越えるまで、基準劣化パターンＰ１１、Ｐ１２、Ｐ１３を作成するための計算を実行する。図７で示した例においては、２周目の運行の中の「運行３」の終了日時が、時間（蓄電装置交換日時１５６）ｔ３を越えたため、同じ運行を２周分実施した段階で計算を終了している。この際、基準劣化パターンＰ１３は、運行終了日時における最終用基準劣化パターンとなる。 After “operation 2”, the deterioration state at the previous operation end date and time is the starting point, and the reference deterioration pattern from the deterioration speed setting value in each operation (for example, the normal deterioration speed setting value 153b) to the end of each operation. P2 and P3 are created. After the operation ("operation 1" to "operation 3") to which the vehicle (railway vehicle) is assigned ends (after operation period T1 from time t1 to time t2 has elapsed), "operation 3" ends. If the date and time does not exceed the time t3 indicating the storage device replacement date and time 156, the same combination of operations ("operation 1" to "operation 3") is repeated again during the operation period T2 from time t2 to time t4. Calculations for creating the reference deterioration patterns P11, P12, and P13 are executed until the end date and time exceeds the time t3 indicating the power storage device replacement date and time 156. In the example shown in FIG. 7, since the end date / time of “operation 3” in the operation on the second lap exceeds the time (power storage device replacement date / time 156) t3, the calculation is performed when the same operation is performed for two laps. Has ended. At this time, the reference deterioration pattern P13 is the final reference deterioration pattern at the operation end date and time.
　基準劣化パターン計算手段１０７は、ステップ５１１で、運行終了日時が蓄電装置交換日時１５６を超えていると判定した場合、これまでの処理で計算された基準劣化パターンの組み合わせ（基準劣化パターンＰ１、Ｐ２、Ｐ３、Ｐ１１、Ｐ１２、Ｐ１３）を特定し、特定された基準劣化パターンの組み合わせに属する基準劣化パターンのうち最終用基準劣化パターンＰ１３における劣化状態（劣化状態低下量）を、基準劣化パターン暫定値（劣化状態低下量の予測値）１５７として、基準劣化パターン再計算判定手段１０８へ出力し（ステップ５１３）、このルーチンでの処理を終了する。この際、基準劣化パターン計算手段１０７は、起点（劣化状態推定日時）から、鉄道車両に割当てられる運行（１つ以上の組み合わせの運行）が全て終了する運行終了時点まで運転した場合の蓄電装置１０１の劣化状態（劣化状態低下量）を示す基準劣化パターンの組み合わせ（基準劣化パターンＰ１、Ｐ２、Ｐ３、Ｐ１１、Ｐ１２、Ｐ１３）を特定することになる。 If the reference deterioration pattern calculation means 107 determines in step 511 that the operation end date / time has exceeded the power storage device replacement date / time 156, the reference deterioration pattern combination (reference deterioration patterns P1, P2) calculated in the processing so far is determined. , P3, P11, P12, P13), and among the reference deterioration patterns belonging to the specified combination of reference deterioration patterns, the deterioration state (deterioration state decrease amount) in the final reference deterioration pattern P13 is determined as the reference deterioration pattern provisional value. (Predicted value of deterioration state reduction amount) 157 is output to the reference deterioration pattern recalculation determining means 108 (step 513), and the processing in this routine is terminated. At this time, the reference deterioration pattern calculation means 107 is the power storage device 101 in the case of driving from the starting point (deterioration state estimation date / time) to the end of operation at which all the operations (operation of one or more combinations) assigned to the railway vehicle are completed. A combination of reference deterioration patterns (reference deterioration patterns P1, P2, P3, P11, P12, and P13) indicating the deterioration state (deterioration state decrease amount) of the above is specified.
　基準劣化パターン計算手段１０７の処理によって、運行毎に適切な基準劣化パターンを計算することができる。 By the processing of the reference deterioration pattern calculation means 107, an appropriate reference deterioration pattern can be calculated for each operation.
[基準劣化パターン再計算判定手段１０６]
　図８は、基準劣化パターン再計算判定手段１０８の内部処理を示すフローチャートである。この処理は、ＣＰＵが、基準劣化パターン再計算判定プログラムを実行することにより開始される。 [Reference degradation pattern recalculation judgment means 106]
FIG. 8 is a flowchart showing the internal processing of the reference deterioration pattern recalculation determining means 108. This process is started when the CPU executes a reference deterioration pattern recalculation determination program.
　まず、基準劣化パターン再計算判定手段１０８は、基準劣化パターン計算手段１０７の出力による基準劣化パターン暫定値１５７と蓄電装置交換計画設定手段１０６の出力による蓄電装置交換基準値１６６とを比較し、基準劣化パターン暫定値１５７における劣化状態が蓄電装置交換基準値１６６を上回るか否かを判定し（ステップ８０１）、基準劣化パターン暫定値１５７における劣化状態が蓄電装置交換基準値１６６を上回る場合はステップ８０２へ進み、基準劣化パターン暫定値１５７における劣化状態が蓄電装置交換基準値１６６を上回らない場合はステップ８０３へ進む。 First, the reference deterioration pattern recalculation determination unit 108 compares the reference deterioration pattern provisional value 157 output from the reference deterioration pattern calculation unit 107 with the power storage device replacement reference value 166 output from the power storage device replacement plan setting unit 106, It is determined whether or not the deterioration state in the temporary deterioration pattern value 157 exceeds the power storage device replacement reference value 166 (step 801). If the deterioration state in the temporary deterioration value reference value 157 exceeds the power storage device replacement reference value 166, step 802 is performed. If the deterioration state in the reference deterioration pattern provisional value 157 does not exceed the power storage device replacement reference value 166, the process proceeds to step 803.
　図９は、ステップ８０１における判定の一例を示す特性図である。図９(a)は、基準劣化パターン暫定値１５７における劣化状態が蓄電装置交換基準値１６６を下回っている場合である。この場合、基準劣化パターン再計算判定手段１０８は、蓄電装置交換日時である時間ｔ３まで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値（状態）に維持できないと判定する。一方、図９(b)は、基準劣化パターン暫定値１５７における劣化状態が蓄電装置交換基準値１６６を上回っている場合である。この場合、基準劣化パターン再計算判定手段１０８は、蓄電装置交換日時の時間ｔ３まで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できると判定する。なお、図９(b)における蓄電装置交換基準値１６６は、図９(a)における蓄電装置交換基準値１６６よりも低いレベルに設定されている。 FIG. 9 is a characteristic diagram showing an example of determination in step 801. FIG. 9A shows a case where the deterioration state in the reference deterioration pattern provisional value 157 is lower than the power storage device replacement reference value 166. In this case, the reference deterioration pattern recalculation determination unit 108 determines that the deterioration state of the power storage device 101 cannot be maintained at a value (state) exceeding the power storage device replacement reference value 166 until time t3 that is the power storage device replacement date and time. On the other hand, FIG. 9B shows a case where the deterioration state in the reference deterioration pattern provisional value 157 exceeds the power storage device replacement reference value 166. In this case, the reference deterioration pattern recalculation determination unit 108 determines that the deterioration state of the power storage device 101 can be maintained at a value exceeding the power storage device replacement reference value 166 until time t3 of the power storage device replacement date and time. Note that the power storage device replacement reference value 166 in FIG. 9B is set to a level lower than the power storage device replacement reference value 166 in FIG. 9A.
　基準劣化パターン再計算判定手段１０８は、ステップ８０１で、基準劣化パターン暫定値１５７における劣化状態（劣化状態低下量）が蓄電装置交換基準値１６６を上回っている（超えている）と判定した場合、基準劣化パターン暫定値１５７を基準劣化パターン確定値１５８として、電力制御手段１０９へ出力し（ステップ８０２）、その後、このルーチンでの処理を終了する。 When the reference deterioration pattern recalculation determination means 108 determines in step 801 that the deterioration state (deterioration state decrease amount) in the reference deterioration pattern provisional value 157 exceeds (exceeds) the power storage device replacement reference value 166, The reference deterioration pattern provisional value 157 is output as the reference deterioration pattern fixed value 158 to the power control means 109 (step 802), and then the processing in this routine is terminated.
　一方、基準劣化パターン再計算判定手段１０８は、ステップ８０１で、基準劣化パターン暫定値１５７における劣化状態が蓄電装置交換基準値１６６を上回らないと判定した場合、基準劣化パターン計算手段１０７に対して、基準劣化パターン暫定値１５７を再計算するよう要請するために、再計算指令１７８を基準劣化パターン計算手段１０７へ出力し（ステップ８０３）、ステップ８０４へ進む。 On the other hand, if the reference deterioration pattern recalculation determination unit 108 determines in step 801 that the deterioration state in the reference deterioration pattern provisional value 157 does not exceed the power storage device replacement reference value 166, the reference deterioration pattern calculation unit 107 In order to request recalculation of the reference deterioration pattern provisional value 157, a recalculation command 178 is output to the reference deterioration pattern calculation means 107 (step 803), and the process proceeds to step 804.
　基準劣化パターン再計算判定手段１０８は、ステップ８０４では、基準劣化パターン計算手段１０７に対して、蓄電装置１０１の劣化速度を抑えるための劣化速度選択情報１６８を出力する。劣化速度選択情報１６８としては、図６の例で示したように、一部の運行に対して、蓄電装置劣化維持用の劣化速度設定値を用いるよう設定しても良いし、全ての運行に対して、蓄電装置劣化維持用の劣化速度設定値を用いるよう設定しても良い。また、あらかじめ一部の運行に対して蓄電装置劣化維持用の劣化速度設定値を用いるよう設定しておき、基準劣化パターン暫定値１５７の再計算を繰り返す毎に、蓄電装置劣化維持用の劣化速度設定値を用いる運行を増やしていくよう設定しても良い。 In step 804, the reference deterioration pattern recalculation determination unit 108 outputs deterioration rate selection information 168 for suppressing the deterioration rate of the power storage device 101 to the reference deterioration pattern calculation unit 107. As the deterioration speed selection information 168, as shown in the example of FIG. 6, it may be set to use a deterioration speed set value for maintaining the deterioration of the power storage device for some operations, or for all operations. On the other hand, the deterioration rate setting value for maintaining the deterioration of the power storage device may be used. In addition, a deterioration rate set value for maintaining the deterioration of the power storage device is set to be used in advance for a part of the operation, and the deterioration rate for maintaining the deterioration of the storage device is repeated every time the recalculation of the reference deterioration pattern provisional value 157 is repeated. You may set so that the operation using a set value may increase.
　図１０は、基準劣化パターン暫定値の特性図であって、（ａ）は、再計算をしていない基準劣化パターン暫定値１５７の特性図であり、（ｂ）は、一度再計算した後の基準パターン暫定値１５７の特性図である。図１０（ａ）は、図９（ａ）と同様に、蓄電装置劣化維持用の劣化速度設定値１５３ｃを使用して基準劣化パターン暫定値１５７を再計算していない場合の特性図であるので、基準劣化パターン暫定値１５７における劣化状態（劣化状態低下量）が蓄電装置交換基準値１６６を下回っており、蓄電装置交換日時の時間ｔ３まで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できないと判定される。 FIG. 10 is a characteristic diagram of the reference deterioration pattern provisional value, (a) is a characteristic diagram of the reference deterioration pattern provisional value 157 that has not been recalculated, and (b) is a graph after recalculation once. FIG. 10 is a characteristic diagram of a reference pattern provisional value 157. FIG. 10A is a characteristic diagram when the reference deterioration pattern provisional value 157 is not recalculated using the deterioration rate set value 153c for maintaining the deterioration of the power storage device, similarly to FIG. 9A. The deterioration state (deterioration state reduction amount) in the reference deterioration pattern provisional value 157 is lower than the storage device replacement reference value 166, and the deterioration state of the storage device 101 is determined as the storage device replacement reference value until time t3 of the storage device replacement date and time. It is determined that the value exceeding 166 cannot be maintained.
　一方、図１０（ｂ）は、１周目と２周目の「運行２」における基準劣化パターンＰ２１、Ｐ１２１を、蓄電装置劣化維持用の劣化速度設定値１５３ｃを用いて計算し、基準劣化パターンの組み合わせに（基準劣化パターンＰ１、Ｐ２１、Ｐ３、Ｐ１１、Ｐ１２１、Ｐ１３）に属する基準劣化パターンのうち最終用基準劣化パターンＰ１３の劣化状態（劣化状態低下量）から基準劣化パターン暫定値１５７を再計算した場合の特性図である。この場合、図９（ｂ）のように、蓄電装置交換基準値１６６のレベルを下げなくても、蓄電装置交換日時の時間ｔ３まで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できると判定される。このように、少なくとも一部の運行における劣化速度設定値を変えて、基準劣化パターン暫定値１５７の再計算を実施することで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できる基準劣化パターンの組み合わせを運行に応じて設定することができる。 On the other hand, FIG. 10B calculates the reference deterioration patterns P21 and P121 in “operation 2” in the first and second laps using the deterioration rate set value 153c for maintaining the deterioration of the power storage device, and the reference deterioration pattern. Of the reference deterioration patterns belonging to (reference deterioration patterns P1, P21, P3, P11, P121, P13), the reference deterioration pattern provisional value 157 is restored from the deterioration state (deterioration state decrease amount) of the final reference deterioration pattern P13. It is a characteristic view at the time of calculating. In this case, as shown in FIG. 9B, the degradation state of the power storage device 101 can be changed to the power storage device replacement reference value 166 until the time t3 of the power storage device replacement date and time without lowering the level of the power storage device replacement reference value 166. It is determined that the value can be maintained above the value. Thus, by changing the deterioration speed setting value in at least some of the operations and recalculating the reference deterioration pattern provisional value 157, the deterioration state of the power storage device 101 is a value that exceeds the power storage device replacement reference value 166. A combination of reference deterioration patterns that can be maintained in accordance with operation can be set.
　本実施例において、基準劣化パターン再計算判定手段１０８は、基準劣化パターン計算手段１０７の出力による１つ以上の基準劣化パターンの組み合わせを基に蓄電装置１０１の劣化状態を判定する劣化状態判定手段として機能する。この際、劣化状態判定手段は、基準劣化パターン計算手段１０７の出力による１つ以上の基準劣化パターンの組み合わせを基に蓄電装置交換日時（時間ｔ３）における運行が全て終了する運行終了時点における蓄電装置１０１の劣化状態低下量が蓄電装置交換基準値１６６を超えているか否かを判定し、運行終了時点における蓄電装置１０１の劣化状態低下量が蓄電装置交換基準値１６６を超えていると判定したことを条件に、１つ以上の基準劣化パターンの組み合わせを蓄電装置１０１の充放電電力制御に用いられる基準劣化パターン確定値として出力する。 In this embodiment, the reference deterioration pattern recalculation determination unit 108 serves as a deterioration state determination unit that determines the deterioration state of the power storage device 101 based on a combination of one or more reference deterioration patterns output from the reference deterioration pattern calculation unit 107. Function. At this time, the deterioration state determining means is a power storage device at the end of operation when all operations on the power storage device replacement date and time (time t3) are completed based on a combination of one or more reference deterioration patterns based on the output of the reference deterioration pattern calculating means 107. It is determined whether or not the deterioration state decrease amount of 101 exceeds the power storage device replacement reference value 166, and it is determined that the deterioration state decrease amount of the power storage device 101 at the end of operation exceeds the power storage device replacement reference value 166. As a condition, a combination of one or more reference deterioration patterns is output as a reference deterioration pattern fixed value used for charge / discharge power control of the power storage device 101.
　また、劣化状態判定手段は、運行終了時点における蓄電装置１０１の劣化状態低下量が蓄電装置交換基準値１６６を超えているか否かを判定する場合、運行終了時点における蓄電装置１０１の劣化状態低下量を、基準劣化パターン暫定値１５７として、基準劣化パターン暫定値１５７と蓄電装置交換基準値１６６とを比較し、基準劣化パターン暫定値１５７が蓄電装置交換基準値１６６を超えていることを条件に、蓄電装置交換日時まで蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を超える値に維持できると判定し、基準劣化パターン暫定値１５７が蓄電装置交換基準値１６６以下の場合、蓄電装置交換日時まで蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を超える値に維持できないと判定する。これにより、蓄電装置交換日時まで蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を超える値に維持できるか否かを判別することができる。 In addition, when the deterioration state determination unit determines whether or not the deterioration state decrease amount of the power storage device 101 at the time when the operation ends exceeds the power storage device replacement reference value 166, the deterioration state decrease amount of the power storage device 101 at the time when the operation ends. As a reference deterioration pattern provisional value 157, the reference deterioration pattern provisional value 157 and the power storage device replacement reference value 166 are compared, and the condition that the reference deterioration pattern provisional value 157 exceeds the power storage device replacement reference value 166, When it is determined that the deterioration state of the power storage device 101 can be maintained at a value exceeding the power storage device replacement reference value 166 until the power storage device replacement date and time, and the reference deterioration pattern provisional value 157 is less than or equal to the power storage device replacement reference value 166, the power storage device replacement date and time It is determined that the deterioration state of the power storage device 101 cannot be maintained at a value exceeding the power storage device replacement reference value 166. Thereby, it is possible to determine whether or not the deterioration state of power storage device 101 can be maintained at a value exceeding power storage device replacement reference value 166 until the power storage device replacement date and time.
　また、劣化状態判定手段は、蓄電装置交換日時まで蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を超える値に維持できないと判定した場合、基準劣化パターン計算手段１０７に対して再計算を指令する。この場合、基準劣化パターン計算手段１０７は、再計算の指令を受ける前に特定した、１以上の基準劣化パターンの組み合わせに属する基準劣化パターンとは劣化速度設定値が異なる１以上の基準劣化パターンを含む１以上の基準劣化パターンの組み合わせを再度特定し、再度特定された１以上の基準劣化パターンの組み合わせを劣化状態判定手段に出力する。劣化状態判定手段において、再度特定された１以上の基準劣化パターンの組み合わせを用いて、蓄電装置１０１の劣化状態を判定することで、蓄電装置交換日時まで蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を超える値に維持できると判定される可能性が高くなる。すなわち、少なくとも一部の運行における劣化速度設定値を変えて、基準劣化パターン暫定値１５７の再計算を実施することで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できる基準劣化パターンの組み合わせを、鉄道車両の運行に応じて設定することが可能になる。 Further, when the deterioration state determination unit determines that the deterioration state of the power storage device 101 cannot be maintained at a value exceeding the power storage device replacement reference value 166 until the storage device replacement date and time, the deterioration state determination unit recalculates the reference deterioration pattern calculation unit 107. Command. In this case, the reference deterioration pattern calculation unit 107 determines one or more reference deterioration patterns having a deterioration rate setting value different from the reference deterioration pattern belonging to the combination of one or more reference deterioration patterns specified before receiving the recalculation instruction. The combination of one or more reference deterioration patterns that are included is specified again, and the combination of one or more reference deterioration patterns that are specified again is output to the deterioration state determining means. In the deterioration state determination means, the deterioration state of the power storage device 101 is determined using the combination of one or more reference deterioration patterns specified again, so that the deterioration state of the power storage device 101 is replaced until the power storage device replacement date and time. There is a high possibility that it is determined that the reference value 166 can be maintained at a value exceeding the reference value 166. That is, the deterioration state of the power storage device 101 is maintained at a value exceeding the power storage device replacement reference value 166 by changing the deterioration speed setting value in at least a part of the operation and recalculating the reference deterioration pattern provisional value 157. It is possible to set a combination of possible reference deterioration patterns according to the operation of the railway vehicle.
　本実施例によれば、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できない、と一度判定された場合でも、少なくとも一部の運行における劣化速度設定値を変えて、基準劣化パターン暫定値１５７の再計算を実施することで、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できる基準劣化パターンの組み合わせを、鉄道車両の運行に応じて設定することができる。結果として、設定された基準劣化パターンの組み合わせを、電力制御手段１５８が蓄電装置１０１の充放電電力制御に利用することで、蓄電装置１０１に対して充放電電力を制限することなく、蓄電装置１０１を運転することができ、鉄道車両本来の走行性能を発揮することができる。 According to the present embodiment, even if it is once determined that the deterioration state of the power storage device 101 cannot be maintained at a value exceeding the power storage device replacement reference value 166, the deterioration speed setting value in at least a part of the operation is changed, By recalculating the reference deterioration pattern provisional value 157, a combination of reference deterioration patterns that can maintain the deterioration state of the power storage device 101 at a value exceeding the power storage device replacement reference value 166 is set according to the operation of the railway vehicle. can do. As a result, the combination of the set reference deterioration patterns is used by the power control unit 158 for charge / discharge power control of the power storage device 101, so that the power storage device 101 is not limited to charge / discharge power. Can be driven, and the running performance inherent to railway vehicles can be exhibited.
(実施例２)
　蓄電装置は、劣化が進行するにつれて劣化速度が遅くなる傾向がある。そのため、その時々の劣化状態に応じて適切な劣化速度設定値を設定することで、基準劣化パターンをより高精度に計算することができる。そこで、実施例２では、劣化速度設定値を、蓄電装置の劣化状態に応じて設定し、基準劣化パターンを計算する例を示す。 (Example 2)
The power storage device tends to have a slower deterioration rate as the deterioration progresses. Therefore, the reference deterioration pattern can be calculated with higher accuracy by setting an appropriate deterioration speed setting value according to the deterioration state at that time. Therefore, in the second embodiment, an example is shown in which the deterioration rate set value is set according to the deterioration state of the power storage device and the reference deterioration pattern is calculated.
　図１１は、実施例２における移動体の蓄電装置管理システムの構成を示す構成図である。図１１において、実施例２における蓄電装置管理システムは、劣化速度設定値データベース１０３から出力される情報として、劣化速度設定値情報１５３の代わりに劣化速度設定値情報１１５３（１１５３Ａ、１１５３Ｂ）を用い、基準劣化パターン計算手段１０７の代わりに、基準劣化パターン計算手段１１０７を用いたものであり、他の構成については実施例１と同じであるため、それらの説明を省略する。以下、実施例１と異なる部分について説明する。 FIG. 11 is a configuration diagram illustrating a configuration of a mobile storage device management system according to the second embodiment. In FIG. 11, the power storage device management system according to the second embodiment uses deterioration rate setting value information 1153 (1153A, 1153B) instead of the deterioration rate setting value information 153 as information output from the deterioration rate setting value database 103. Since the reference deterioration pattern calculation unit 1107 is used instead of the reference deterioration pattern calculation unit 107, and other configurations are the same as those in the first embodiment, description thereof will be omitted. Hereinafter, a different part from Example 1 is demonstrated.
　まず、劣化速度設定値情報１１５３について説明する。図１２は、運行毎の劣化速度設定値を、その時々の劣化状態に応じて設定した劣化速度設定値情報１１５３の構成図であって、（ａ）は、劣化速度設定値情報１１５３に属する通常用の劣化速度設定値情報１１５３Ａの構成図であり、（ｂ）は、劣化速度設定値情報１１５３に属する蓄電装置劣化維持用の劣化速度設定値情報１１５３Ｂの構成図である。図１２（ａ）において、通常用の劣化速度設定値情報１１５３Ａは、割当てられた運行１１５３ａ１、劣化状態１１５３ａ２から構成される。割当てられた運行１１５３ａ１には、車両（鉄道車両）に割当てられた運行を特定する情報として、「１」、「２」、「３」などの情報が記録される。劣化状態１１５３ａ２は、複数のブロック（「０％」、「１０％」、「２０％」、・・・）に分割されており、各ブロックには、その車両の運行によってどれだけ劣化（蓄電装置１０１の劣化）が進行するかを表す速度設定値の情報が記録される。例えば、運行１回あたりの容量維持率低下量（％）を示す速度設定値の情報が記録される。具体的には、割当てられた運行１１５３ａ１で「１」の運行（「運行１」）が特定される場合、劣化状態１１５３ａ２の「０％」のブロックには、「０．３」の情報が記録され、「１０％」のブロックには、「０．２」の情報が記録され、「２０％」のブロックには、「０．１５」の情報が記録される。蓄電装置１０１は、劣化が進行するにつれて劣化速度が遅くなる傾向があるので、劣化状態１１５３ａ２の値（％）が大きくなる程、小さい速度設定値が設定されている。 First, the degradation rate setting value information 1153 will be described. FIG. 12 is a configuration diagram of the deterioration speed setting value information 1153 in which the deterioration speed setting value for each operation is set according to the deterioration state at each time, and (a) is a normal belonging to the deterioration speed setting value information 1153. FIG. 6B is a configuration diagram of deterioration rate setting value information 1153B for maintaining the deterioration of the power storage device belonging to the deterioration rate setting value information 1153. FIG. In FIG. 12A, the normal deterioration rate set value information 1153A is composed of an assigned operation 1153a1 and a deterioration state 1153a2. In the assigned operation 1153a1, information such as “1”, “2”, “3”, etc. is recorded as information specifying the operation assigned to the vehicle (railway vehicle). The deterioration state 1153a2 is divided into a plurality of blocks (“0%”, “10%”, “20%”,...), And how much deterioration (power storage device) occurs in each block due to the operation of the vehicle. The information of the speed setting value indicating whether or not (deterioration of 101) proceeds is recorded. For example, information on the speed setting value indicating the amount of decrease in capacity maintenance rate per operation (%) is recorded. Specifically, when the assigned operation 1153a1 specifies the operation “1” (“operation 1”), the information “0.3” is recorded in the “0%” block of the deterioration state 1153a2. Then, the information “0.2” is recorded in the “10%” block, and the information “0.15” is recorded in the “20%” block. Since the power storage device 101 has a tendency that the deterioration rate becomes slower as the deterioration progresses, a smaller speed setting value is set as the value (%) of the deterioration state 1153a2 increases.
　図１２（ｂ）において、蓄電装置劣化維持用の劣化速度設定値情報１１５３Ｂは、割当てられた運行１１５３ｂ１、劣化状態１１５３ｂ２から構成される。割当てられた運行１１５３ｂ１には、車両に割当てられた運行を特定する情報として、「１」、「２」、「３」などの情報が記録される。劣化状態１１５３ｂ２は、複数のブロック（「０％」、「１０％」、「２０％」、・・・）に分割されており、各ブロックには、その車両の運行によってどれだけ劣化（蓄電装置１０１の劣化）が進行するかを表す速度設定値の情報が記録される。例えば、運行１回あたりの容量維持率低下量（％）を示す速度設定値の情報が記録される。具体的には、割当てられた運行１１５３ｂ１で「１」の運行（「運行１」）が特定される場合、劣化状態１１５３ｂ２の「０％」のブロックには、「０．２」の情報が記録され、「１０％」のブロックには、「０．１」の情報が記録され、「２０％」のブロックには、「０．０５」の情報が記録される。蓄電装置１０１は、劣化が進行するにつれて劣化速度が遅くなる傾向があるので、劣化状態１１５３ｂ２の値（％）が大きくなる程、小さい速度設定値が設定されている。 In FIG. 12 (b), the degradation rate set value information 1153B for maintaining the degradation of the power storage device is composed of an assigned operation 1153b1 and a degradation state 1153b2. In the assigned operation 1153b1, information such as “1”, “2”, “3”, etc. is recorded as information specifying the operation assigned to the vehicle. The deterioration state 1153b2 is divided into a plurality of blocks (“0%”, “10%”, “20%”,...), And each block is deteriorated by how much the vehicle is operating (power storage device). The information of the speed setting value indicating whether or not (deterioration of 101) proceeds is recorded. For example, information on the speed setting value indicating the amount of decrease in capacity maintenance rate per operation (%) is recorded. Specifically, when the assigned operation 1153b1 specifies the operation “1” (“operation 1”), the information “0.2” is recorded in the “0%” block of the deterioration state 1153b2. Then, information “0.1” is recorded in the “10%” block, and information “0.05” is recorded in the “20%” block. Since the power storage device 101 has a tendency that the deterioration speed becomes slower as the deterioration progresses, a smaller speed setting value is set as the value (%) of the deterioration state 1153b2 increases.
　なお、この運行毎の劣化速度設定値は、列車運転シミュレーションの結果などから作成しても良いし、模範的な運転操作を実施する運転手が運転した際の実測値から作成しても良い。 It should be noted that the deterioration speed setting value for each operation may be created from the result of a train operation simulation or the like, or may be created from an actual measurement value when a driver who performs an exemplary driving operation drives.
　続いて、基準劣化パターン計算手段段１１０７の内部処理について説明する。図１３は、実施例２における基準劣化パターン計算手段１１０７の内部処理を示すフローチャートである。図１３における処理のうち、ステップ１３０１～ステップ１３０７は、図５のステップ５０１～ステップ５０７と同様であり、ステップ１３０９～ステップ１３１３は、図５のステップ５０９～ステップ５１３７と同様であるので、以下、ステップ１３０８の処理について説明する。 Subsequently, the internal processing of the reference deterioration pattern calculation means stage 1107 will be described. FIG. 13 is a flowchart illustrating the internal processing of the reference deterioration pattern calculation unit 1107 according to the second embodiment. 13, steps 1301 to 1307 are the same as steps 501 to 507 in FIG. 5, and steps 1309 to 1313 are the same as steps 509 to 5137 in FIG. 5. The process of step 1308 will be described.
　基準劣化パターン計算手段段１１０７は、ステップ１３０８では、劣化速度設定値情報１１５３を基に、参照中のループの運行と、前のループで計算した基準劣化パターンの最終的な劣化状態から、劣化速度設定値を参照する。この際、参照中のループの運行における劣化速度選択情報１１５３が、通常用の劣化速度選択情報１１５３Ａであれば、劣化状態１１５３ａ２の中から、前のループで計算した基準劣化パターンの最終的な劣化状態に対応した劣化速度設定値を参照する。例えば、「運行１」における劣化状態が、「１０％」であれば、劣化速度設定値として、「０．２」を参照する。 In step 1308, the reference deterioration pattern calculation means stage 1107 determines the deterioration rate from the operation of the reference loop and the final deterioration state of the reference deterioration pattern calculated in the previous loop based on the deterioration rate set value information 1153. Refer to the setting value. At this time, if the deterioration speed selection information 1153 in the operation of the loop being referred to is the normal deterioration speed selection information 1153A, the final deterioration of the reference deterioration pattern calculated in the previous loop is selected from the deterioration states 1153a2. Refer to the degradation rate setting value corresponding to the condition. For example, if the deterioration state in “operation 1” is “10%”, “0.2” is referred to as the deterioration speed setting value.
　一方、参照中のループの運行における劣化速度選択情報１１５３が、蓄電装置劣化維持用の劣化速度選択情報１１５３Ｂであれば、劣化状態１１５３ｂ２の中から、前のループで計算した基準劣化パターンの最終的な劣化状態に対応した劣化速度設定値を参照する。例えば、「運行１」における劣化状態が、「１０％」であれば、劣化速度設定値として、「０．１」を参照する。 On the other hand, if the deterioration rate selection information 1153 in the operation of the loop being referred to is the deterioration rate selection information 1153B for maintaining the power storage device deterioration, the final reference deterioration pattern calculated in the previous loop is selected from the deterioration states 1153b2. Refer to the degradation rate setting value corresponding to the particular degradation state. For example, if the deterioration state in “operation 1” is “10%”, “0.1” is referred to as the deterioration speed setting value.
　なお、基準劣化パターン計算手段１０７は、ステップ１３０９では、ステップ１３０８で参照した劣化速度設定値（劣化状態１１５３ａ２又は１１５３ｂ２で特定される劣化速度設定値）を用いて、起点からの劣化状態低下量を求め、起点の日時と参照中のループの運行にかかる時間から、参照中のループの運行が終了する日時（運行終了日時）までの基準劣化パターンを計算する。 In step 1309, the reference deterioration pattern calculation unit 107 uses the deterioration speed setting value (deterioration speed setting value specified by the deterioration state 1153 a 2 or 1153 b 2) referred to in step 1308 to calculate the deterioration state decrease amount from the starting point. The reference deterioration pattern from the date and time of the starting point and the time taken to operate the loop being referred to to the date and time when the operation of the loop being referred to ends (operation end date and time) is calculated.
　本実施例において、基準劣化パターン計算手段１０７は、劣化速度選択情報１１５３（１１５３Ａ、１１５３Ｂ）に属する劣化状態１１５３ａ２又は１１５３ｂ２の複数のブロックのうち、劣化状態推定手段１０２の推定による蓄電装置１０１の劣化状態推定値（％）に対応したブロックを選択し、選択したブロックに設定された速度設定値を用いた基準劣化パターンを、基準劣化パターンの組み合わせに属する基準劣化パターンとして特定する。これにより、蓄電装置１０１の劣化速度が遅くなる傾向にあっても、蓄電装置１０１の劣化状態に応じて適切な劣化速度設定値を用いた基準劣化パターンの組み合わせを、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できる基準劣化パターンの組み合わせとして特定することができる。 In the present embodiment, the reference deterioration pattern calculation unit 107 deteriorates the power storage device 101 based on the estimation of the deterioration state estimation unit 102 among a plurality of blocks of the deterioration state 1153a2 or 1153b2 belonging to the deterioration speed selection information 1153 (1153A, 1153B). A block corresponding to the estimated state value (%) is selected, and a reference deterioration pattern using the speed setting value set in the selected block is specified as a reference deterioration pattern belonging to a combination of reference deterioration patterns. As a result, even if the deterioration rate of the power storage device 101 tends to be slow, the combination of the reference deterioration pattern using the appropriate deterioration rate setting value according to the deterioration state of the power storage device 101 is changed to the deterioration state of the power storage device 101. The combination of the reference deterioration patterns that can be maintained at a value that exceeds the power storage device replacement reference value 166 can be specified.
　本実施例によれば、蓄電装置１０１の劣化速度が遅くなる傾向にあっても、蓄電装置１０１の劣化状態に応じて適切な劣化速度設定値を用いた基準劣化パターンの組み合わせであって、蓄電装置１０１の劣化状態を、蓄電装置交換基準値１６６を上回る値に維持できる基準劣化パターンの組み合わせを、鉄道車両の運行に応じて設定することができる。 According to the present embodiment, even when the deterioration rate of the power storage device 101 tends to be slow, the combination of the reference deterioration patterns using the appropriate deterioration rate setting value according to the deterioration state of the power storage device 101, A combination of reference deterioration patterns capable of maintaining the deterioration state of the device 101 at a value exceeding the power storage device replacement reference value 166 can be set according to the operation of the railway vehicle.
