（１）第１実施形態
（１−１）構成
以下、図１に基づいて、本発明に係る燃料電池発電システム（以下、燃料電池システムという）の全体構成について説明する。 (1) Configuration of First Embodiment (1-1) The overall configuration of a fuel cell power generation system (hereinafter referred to as a fuel cell system) according to the present invention will be described below with reference to FIG.

図１において、異常検出手段１は、当該燃料電池システムの改質器や空気供給装置等の各装置に備えられた各種のセンサ類から燃料電池システム内の流体温度や圧力、内部機器の出力等の情報を収集し、それらの情報の中から適正な運転条件から逸脱した値を検出する手段である。   In FIG. 1, the abnormality detection means 1 includes a fluid temperature and pressure in the fuel cell system, an output of an internal device, etc. from various sensors provided in each device such as a reformer and an air supply device of the fuel cell system. The information is collected, and a value deviating from an appropriate operating condition is detected from the information.

システム情報保存手段２は、システム異常発生時に、前記異常検出手段１により検出された異常状態情報とその時のシステム状態を異常状態情報記憶部３に保存する手段である。   The system information storage unit 2 is a unit that stores the abnormal state information detected by the abnormality detection unit 1 and the system state at that time in the abnormal state information storage unit 3 when a system abnormality occurs.

異常／復旧シナリオデータベース４は、適正なシステム状態と、想定される異常なシステム状態とを対比して、燃料電池システムにどの様な異常があるかを想定し、それぞれの異常状態に対して適用すべき復旧手順を保存したデータベースである。   Abnormality / recovery scenario database 4 compares the appropriate system state with the expected abnormal system state, assumes what kind of abnormality exists in the fuel cell system, and applies to each abnormal state It is a database that stores recovery procedures to be performed.

システム状態判断手段５は、前記異常状態情報記憶部３と異常／復旧シナリオデータベース４とのデータを対比させ、当該異常状態が、事業者・製造者にて対応すべき重度の異常か、使用者にて対処可能な異常か、あるいは安全に支障なく自動で復旧を試みることが可能な軽度の異常かを判断し、講ずべき対応策を決定する手段である。   The system state determination means 5 compares the data of the abnormal state information storage unit 3 and the abnormality / recovery scenario database 4 to determine whether the abnormal state is a serious abnormality that should be dealt with by the operator / manufacturer. This is a means for determining the countermeasure to be taken by judging whether it is an abnormality that can be dealt with in the case of a minor abnormality that can be automatically restored without any problem in safety.

自動復旧手段６は、前記システム状態判断手段５により、当該異常状態が安全に支障ないと判断された場合に、故障停止した燃料電池システムを自動的に再起動する手段である。   The automatic recovery means 6 is means for automatically restarting the fuel cell system that has stopped due to failure when the system state determination means 5 determines that the abnormal state does not interfere with safety.

情報提供手段７は、前記システム状態判断手段５によって、当該異常状態が安全や機器損壊に関わる可能性がある重度の異常であると判断された場合、あるいは、故障原因が燃料電池システムの外部にあり、使用者によって該故障原因が除去可能であると判断された場合に、使用者に対して、その状況と使用者が行うべき調査、復旧処理方法、事業者・製造者への修理依頼方法等のガイダンスを行うユーザインターフェース装置である。   The information providing means 7 is used when the system state determining means 5 determines that the abnormal state is a serious abnormality that may be related to safety or equipment damage, or the cause of the failure is outside the fuel cell system. Yes, when it is determined by the user that the cause of the failure can be removed, the situation, the investigation to be performed by the user, the recovery processing method, and the repair request method to the operator / manufacturer It is a user interface device that performs guidance such as.

再起動手段８は、使用者によって燃料電池システム以外の原因が除去された場合等に、使用者により燃料電池システムを手動で再起動する手段であり、また、通知手段９は、前記システム状態判断手段５によって、当該異常が燃料電池システムの安全・損壊等に関わると判断されるか、前記異常／復旧シナリオデータベースに当該異常が定義されていないか、または、前記自動復旧手段および再起動手段により再起動中に異常状態が再発した場合等に、事業者、製造者による詳細調査が必要である旨と、燃料電池停止中の留意事項等の所要情報を使用者に通知する手段である。   The restarting means 8 is means for manually restarting the fuel cell system by the user when a cause other than the fuel cell system is removed by the user, and the notifying means 9 is for determining the system state. It is determined by means 5 that the abnormality is related to safety / damage of the fuel cell system, whether the abnormality is not defined in the abnormality / recovery scenario database, or by the automatic recovery means and the restarting means. This is a means for notifying the user of necessary information such as notices when the fuel cell is stopped and the fact that a detailed investigation by the operator or the manufacturer is necessary when an abnormal state reoccurs during restart.

（１−２）作用
上記のような構成を有する燃料電池システムは、以下のように作用する。すなわち、異常検出手段１により燃料電池システムの改質器や空気供給装置等の各部位の温度、出力、流体圧力等の運転情報が常時監視され（ステップ２０１）、それらが適正な運転状態から逸脱した場合には（ステップ２０２）、システム情報保存手段２により、その前後の各運転情報が異常状態情報記憶部３に保存される（ステップ２０３）。 (1-2) Operation The fuel cell system having the above configuration operates as follows. That is, operation information such as temperature, output, fluid pressure and the like of each part such as a reformer and an air supply device of the fuel cell system is constantly monitored by the abnormality detection means 1 (step 201), and they deviate from an appropriate operation state. In the case (step 202), the system information storage unit 2 stores the previous and subsequent driving information in the abnormal state information storage unit 3 (step 203).

その後、燃料電池システムが故障停止に至った場合には（ステップ２０４）、システム状態判断手段５により燃料電池システムの故障状態が判断され（ステップ２０５）、燃料電池システムに予め備えられたシステム異常発生シナリオと状態復旧シナリオとを集めた異常／復旧シナリオデータベース４の中に、今回発生した異常に関する情報があるか否かが判断される（ステップ２０６）。   Thereafter, when the fuel cell system reaches a failure stop (step 204), the failure state of the fuel cell system is determined by the system state determination means 5 (step 205), and a system abnormality provided in advance in the fuel cell system occurs. It is determined whether or not there is information relating to the abnormality that has occurred this time in the abnormality / recovery scenario database 4 in which the scenarios and state recovery scenarios are collected (step 206).

異常／復旧シナリオデータベース４の中に、今回発生した異常に関する情報があると判断された場合には、異常状態情報記憶部３に保存された異常発生前後の運転情報と、異常／復旧シナリオデータベース４の情報とが対比される。   When it is determined that the abnormality / recovery scenario database 4 has information on the abnormality that has occurred this time, the operation information before and after the occurrence of the abnormality stored in the abnormality state information storage unit 3 and the abnormality / recovery scenario database 4 Is contrasted with the information.

そして、システム状態判断手段５により、システムの異常状態が想定され、異常の重要度が判別され、状態復旧手順等が選定され、当該異常要因が燃料電池システムの運転の安全に支障がないと判断され、また異常の原因が一時的な要因によるもの、例えば一部機器の昇温、降温遅れや、点火装置の不調や流体圧力の一時低下等、自動復旧が可能であると判断された場合には（ステップ２０７）、自動復旧手段６により自動で運転状態の復旧処理が行われ（ステップ２０８）、自動復旧処理が正常に終了したか否かが判断され（ステップ２０９）、正常に終了した場合には燃料電池システムの復旧処理を終了する。   Then, the system state determination means 5 assumes an abnormal state of the system, determines the importance level of the abnormality, selects a state recovery procedure, etc., and determines that the abnormality factor does not hinder the safety of the operation of the fuel cell system. In addition, when the cause of the abnormality is due to a temporary factor, for example, it is determined that automatic recovery is possible, such as temperature rise or fall of some equipment, malfunction of the ignition device, or temporary drop in fluid pressure. (Step 207) When the automatic restoration means 6 automatically performs the restoration process of the operation state (Step 208), it is determined whether or not the automatic restoration process has been completed normally (Step 209). Then, the recovery process of the fuel cell system is finished.

一方、ステップ２０７において、異常の要因が軽微なものではなく、自動復旧の対象ではないと判断された場合にはステップ２１０に進み、前記システム状態判断手段５により、当該異常が使用者の調査・復旧処理の対象か否か、言い換えれば、燃料電池システム自体には異常がないと判断され、当該異常要因が外部の条件によるもの、例えば、燃料の供給停止や系統電圧の異常等と判断された場合には、情報提供手段７により、想定される異常の内容と使用者によって調査・確認すべき内容が、リモコン等のユーザインターフェース装置を介して使用者に通知される（ステップ２１１）。   On the other hand, if it is determined in step 207 that the cause of the abnormality is not minor and is not subject to automatic recovery, the process proceeds to step 210, and the system state determination means 5 determines whether the abnormality is Whether or not it is a target for restoration processing, in other words, it is determined that there is no abnormality in the fuel cell system itself, and the abnormality factor is determined to be due to an external condition, for example, a fuel supply stop or an abnormality in the system voltage In this case, the information providing means 7 notifies the user of the assumed abnormal content and the content to be investigated / confirmed by the user via a user interface device such as a remote controller (step 211).

前記情報提供手段７より通知された情報により、使用者にて燃料電池システム外部の異常要因が除去された後（ステップ２１２）、使用者にて運転再開を試みる場合、再起動手段７により、異常のあったパラメータを含めシステム状態を監視し、安全に支障がないよう運転状態の復旧処理が行われる（ステップ２１３）。そして、ユーザによる再起動処理が正常に終了したか否かが判断され（ステップ２１４）、正常に終了した場合には燃料電池システムの復旧処理を終了する。   After the abnormal condition outside the fuel cell system is removed by the user by the information notified from the information providing means 7 (step 212), when the user tries to resume operation, the restart means 7 The system state is monitored including the parameters, and the operation state recovery process is performed so that there is no problem in safety (step 213). Then, it is determined whether or not the restart process by the user has ended normally (step 214). If the restart process has ended normally, the recovery process of the fuel cell system ends.

一方、ステップ２１０において、前記システム状態判断手段５により、当該異常がユーザの調査・復旧の対象ではない、言い換えれば、当該異常が燃料電池システムの運転の安全・損壊等に関わる重度の異常であると判断されるか、ステップ２０６において、前記異常／復旧シナリオデータベース４に当該異常が定義されていないか、または、ステップ２０９又はステップ２１４において、前記自動復旧手段６又は再起動手段７により運転状態の復旧処理中に、再度異常が発生した場合には、燃料電池システムを安全に停止させ（ステップ２１５）、事業者、製造者による詳細調査が必要である旨と、燃料電池システムの停止中の留意事項等の所要情報がリモコン等のユーザインターフェース装置を介して使用者に通知される（ステップ２１６）。   On the other hand, in step 210, the system state determination means 5 determines that the abnormality is not subject to user investigation / recovery, in other words, the abnormality is a serious abnormality related to safety / damage of the operation of the fuel cell system. In step 206, the abnormality / recovery scenario database 4 does not define the abnormality, or in step 209 or 214, the automatic recovery means 6 or the restarting means 7 If an abnormality occurs again during the restoration process, the fuel cell system is safely stopped (step 215), and a detailed investigation by the operator or manufacturer is necessary, and the fuel cell system is being stopped. Required information such as matters is notified to the user via a user interface device such as a remote controller (step 21). ).

（１−３）効果
上記のような本発明の燃料電池システムによれば、燃料電池システムが異常停止に至った場合に、異常情報とその時のシステム状態を保存し、そのデータと予め異常／復旧シナリオデータベースに保存されたデータとを比較して、その異常の程度を高精度に判断することができる。 (1-3) Effect According to the fuel cell system of the present invention as described above, when the fuel cell system is abnormally stopped, the abnormality information and the system state at that time are stored, and the data and the abnormality / recovery in advance are stored. The degree of abnormality can be judged with high accuracy by comparing with data stored in the scenario database.

また、発生した異常が、自動復旧が可能な軽度な異常の場合には、直ちに自動復旧処理を行い、使用者により復旧処理が可能な異常の場合には、使用者にその旨を通知し、異常原因の除去方法及び復旧処理方法をガイダンスし、使用者により異常原因が除去された後、復旧処理を実施するよう指示することができる。   In addition, if the anomaly that occurred is a minor anomaly that can be recovered automatically, an automatic recovery process is performed immediately. If an anomaly that can be recovered by the user, an error is notified to the user, Guidance can be given on how to remove the cause of the abnormality and how to restore it, and after the cause of the abnormality has been removed by the user, it can be instructed to carry out the restoration process.

さらに、発生した異常が燃料電池システムの運転の安全・損壊等に関わる重度の異常である場合には、燃料電池システムを安全に停止させ、使用者に事業者、製造者に対して詳細調査及び修理を依頼するよう通知することができるので、発生した異常の程度に応じて、常に適切な復旧処理を実施することができる。これにより、システムの停止時間の短縮化も可能となる。   In addition, if the abnormality that occurred is a serious abnormality related to the safety or damage of the operation of the fuel cell system, the fuel cell system is stopped safely, and the user and the manufacturer are investigated in detail. Since it is possible to notify the request for repair, appropriate recovery processing can always be performed according to the degree of abnormality that has occurred. As a result, the system stop time can be shortened.
