【発明の属する技術分野】
本発明は、自家発電設備が設けられた複数の施設に、前記自家発電設備の停止に伴って、自家発補給電力を託送する自家発補給電力託送方法及び発電施設に関する。
【０００２】
【従来の技術】
上記のように、自家発電設備を所有する施設においては、通常、自ら消費する電力の少なくとも一部を、自家発電設備を運転して発電される電力でまかなっており、その他の不足電力は電力会社等から供給される。
このように自家発電設備を設けた施設において、自家発電設備が、定期検査や定期補修又は故障等の理由により運転を停止した場合に、本来自家発電設備で発電してまかなっていた電力が不足するので、その不足電力を確保する必要がある。
【０００３】
そこで、電力会社との間で自家発補給電力の契約を行い、電力会社から前記不足電力としての自家発補給電力の供給を受けることができる。
しかし、電力会社から供給を受ける自家発補給電力の基本料金は、負荷率別電力の基本料金の１０％割増ししたもの（自家発補給電力を使用しなかった場合は、負荷率別電力の基本料金の１０％割増ししたものの３０％）であり、通常の契約電力と比較して割高である。
尚、負荷率別電力の契約とは、電力会社との間で結ぶ契約種別の一つで、電力の負荷率（契約最大電力に対する使用電力の率）を向上するほど、電力料金を割り引くという内容のものである。
【０００４】
【発明が解決しようとする課題】
電力会社との契約において、上記の自家発補給電力と合わせて電力の供給を受ける場合は、上記の契約最大電力が、通常使用する契約電力と自家発補給電力（自家発電設備の発電能力）との合計値とされ、自ら所有する自家発電設備を運転して自家発補給電力を使用していないときは、負荷率が低くなり、電力料金が高く設定される。
一方、自家発電設備が停止したときに瞬時に自動的に切換えを行い運転を開始する予備発電設備を設置している場合は、自家発補給電力は、自家発電設備の発電能力から予備発電設備の発電能力を差し引いたものとされるため、若干負荷率を向上させることができる。しかし、このように予備発電設備を自家発電設備が設けてある施設に設けても、その予備発電設備は、あくまでも自家発電設備が停止したときに運転を行うものであり、運転頻度は極めて低く、一方その低い運転頻度のわりには、設置スペースの確保や設備管理費及び設備コストの増加等の問題があり、自家発電を行うことによる経済効果が低減する。
従って、本発明は、上記の事情に鑑みて、上記のような自家発電設備が設けられた施設において、自家発補給電力を安価に確保することで、自家発電を行うことによる経済効果を向上させることができる自家発補給電力託送方法及び発電施設を提供することを目的とする。
【０００５】
【課題を解決するための手段】

本発明の自家発補給電力託送方法は、このような予備発電施設を所有する複数の施設において、何れかの施設の自家発電設備が停止したことを認識したときに、その施設の時間持分を消費して、言換えれば施設の時間持分の範囲内で、予備発電設備を運転し、そのときに発電されたその施設の持分である電力を、自家発補給電力としてその施設に託送（電力会社の電力線を借りて電力を供給する。）する、所謂自家発補給電力の自己託送を行うことができる。

【００１１】
さらに、発電施設には、前記受信工程を行うための前記通信手段と、前記運転工程を行うための前記運転手段と、前記時間持分が記憶されている前記記憶手段とを有する管理装置が設けてある。そして、この管理装置は、前記受信工程を行って、予備発電設備を共有する複数の施設から、夫々に設けてある自家発電設備が定期検査又は補修により停止される日時や、自家発電設備が事故等により停止した事実等の停止情報を通信手段により受信して、次に、運転工程を行って、運転手段によりその受信した停止情報に基づいて予備発電設備の運転を行う。そこで、運転手段は、予備発電設備を運転するに、記憶手段に記憶されている停止情報を受信した施設の時間持分を消費して、言換えれば施設の時間持分の範囲内で、予備発電設備を運転し発電を行う。このように発電された電力は、その予備発電機を運転した時間持分を所有する施設のものであるといえる。

【００１４】
尚、これまで説明してきた発電施設に設ける予備発電設備の発電能力及び台数は、それを共有して保有する複数の施設の自家発電設備の発電能力及び停止頻度に基づいて設定される。詳しくは、例えば、夫々の施設の自家発電設備の停止頻度から、同時に停止する可能性がある自家発電設備の台数を推定して、その台数又はそれに安全を考慮した台数を加えた台数を予備発電設備の台数として決定し、その予備発電設備の発電能力は、複数の施設に設けてある夫々の自家発電設備の最大の発電能力に合わせて決定され、このように予備発電設備の発電能力及び台数を設定することで、複数の施設に設けられた自家発電設備に対して好ましい台数及び能力の予備発電設備を設けることができ、夫々の自家発電設備の停止状態に合わせて充分な自家発補給電力を自己託送することができる。
【００１５】
【発明の実施の形態】
本発明の自家発補給電力託送方法及び発電施設について、図面に基づいて説明する。
図１に示す発電施設１は、夫々に自家発電設備３１が設けられた複数の施設３０に、自家発電設備３１の定期検査や定期補修又は故障等の理由による停止に伴って、自家発補給電力を託送するものであり、例えば施設３０以外の管理会社が管理するものである。
詳しくは、発電施設１には、例えば４台の予備発電設備２が設けてあり、これらの予備発電設備２は、前記管理会社等から例えば１００程度の施設３０に分譲されたものである。よって、これらの予備発電設備２は、複数の施設３０が共有して保有するものである。
【００１６】
さらに、発電施設１には、送電手段４が設けてあり、送電手段４により、予備発電設備２を運転して発電された電力は、自家発補給電力として、電力会社５０等が保有する電力線２０を利用して夫々の施設３０に送電可能である。
【００１７】
また、前記予備発電設備２を共有する夫々の施設３０には、通常その施設３０で消費される電力を発電するための自家発電設備３１が設けられており、さらに、その自家発電設備３１が停止したときに、その停止した事実である停止情報を、通信回線４０を介して、発電設備１の後述する管理装置３側に送信する通信装置３２が夫々設けられている。
【００１８】
発電施設１には、管理装置３が設けられており、その管理装置３が、夫々の施設３０に託送する自家発補給電力を発電するために予備発電設備２の運転等を行うのであるが、その管理装置３の特徴構成と共にその自家発補給電力託送方法について以下に説明する。
【００１９】
発電施設１に設けられた管理装置３には、記憶手段１５が設けられており、記憶手段１５には、例えば１ヶ月等の所定の期間において、その所定の期間を、夫々の施設３０の予備発電設備の保有持分により分割して得られた時間を、複数の施設がその予備発電設備を運転することができる時間持分として記憶している。
【００２０】
さらに、管理装置３には、前述の通信回線４０に接続されている通信手段１６と、予備発電設備２の運転を行う運転手段１４と、予備発電設備２に運転指示信号を出力すると共に、送電手段４に電力送電指示信号を出力する出力手段１１とが設けられている。
【００２１】
詳しくは、通信手段１６は、受信工程を行って、自家発電設備３１が停止した施設３０から、自家発補給電力の託送要求としての停止情報を、通信回線４０を介して受信する手段である。
また、運転手段１４は、運転工程を行って、通信手段１６により受信した停止情報に基づいて予備発電設備の運転を行う手段である。また運転手段１４は、予備発電設備２を運転するに、記憶手段１５に記憶されている停止情報を受信した施設の時間持分を消費して、言換えれば施設の時間持分の範囲内で、予備発電設備２を運転し発電を行う。
【００２２】
そして、管理装置３は、送電手段４を働かせて、運転工程を行って運転手段１５により予備発電設備２を運転して発電された電力を、自家発補給電力として、電力会社５０が所有する電力線２０を介して、前記受信工程を行って通信手段１６に停止情報を送信した施設３０に送電する送電工程を行って、自家発補給電力の自己託送を行うのである。
さらに、管理装置３は、このように施設３０への自家発補給電力の送電を行うに、通信手段１６から通信回線４０を介して電力会社５０に電力の託送を開始する旨の報告を行い、さらに、自家発補給電力の供給を受ける施設３０の自家発補給電力の使用量を、通信回線４０を介して監視しながら、その使用量にあった自家発補給電力を発電するように予備発電設備２の運転を行い、電力託送における同時同量のルールを達成させることができ、託送料金をできるだけ節約することができる。
【００２３】
次に、複数の施設３０から委託され発電施設１を管理する管理者は、発電施設１の管理費や予備発電設備２の管理費及び設置スペースの使用料等である固定費と、前記予備発電設備２を運転したときにかかる燃料費及び託送費等の比例費等とを考慮して計算された料金を夫々の施設３０に課金するのであるが、その課金方法について以下に説明する。
まず、発電施設１の管理装置３には、夫々の施設３０へ課金する料金を算出する料金算出手段１２が設けられている。
料金算出手段１２は、例えば１ヶ月毎に夫々の施設３０に課金する料金を算出するのであるが、その料金の内、上記の固定費に対する料金は、予め設定した予備発電設備２等の管理費を考慮した料金を利用する。そして、料金算出手段１２は、記憶手段１５に記憶されている夫々の施設３０の時間持分の残量に基づいて、夫々の施設３０の予備発電設備２を運転させた時間を算出し、その時間に予め燃料費等を考慮した単価を乗じた料金を、比例費に対する料金として利用する。
そして、料金算出手段１２は、上記の固定費及び比例費に対する料金の合計を、夫々の施設３０に課金する料金として、課金データ記憶手段１３に記憶させ、管理者は、その課金データ記憶手段１３に記憶されている料金に基づいて、夫々の施設３０に料金を課金するのである。
【００２４】
これまで説明してきた自家発補給電力託送方法及び発電施設において、所定の期間における前記時間持分をすべて消費し、自家発補給電力の託送を希望する施設は、電力会社から自家発補給電力の供給を受けることができるが、他の施設から時間持分の残量を買い取って、予備発電設備を運転して発電された電力を自家発補給電力として自己託送することもできる。
【００２５】
さらに、所定の期間において前記時間持分が残っている施設においては、その残量に相当する比例費分、管理会社に支払う料金が安くなるのであるが、別に残っている時間持分を消費して予備発電設備２を運転し、発電された電力を他の電力市場において売却し、利益を得ることもできる。

BACKGROUND OF THE INVENTION
The present invention relates to a self-supplied replenishment power delivery method and a power generation facility that entrust self-supplied power to a plurality of facilities provided with self-power generation equipment when the private power generation equipment is stopped.
[0002]
[Prior art]
As mentioned above, facilities that own private power generation facilities usually cover at least a part of the power they consume with the power generated by operating the private power generation facilities. Supplied from etc.
In such a facility equipped with private power generation equipment, when the private power generation equipment stops operation due to periodic inspections, periodic repairs, or malfunctions, the power that was originally generated by the private power generation equipment is insufficient. Therefore, it is necessary to ensure that insufficient power.
[0003]
Therefore, it is possible to make a contract for self-supplied power with a power company and receive the supply of self-supplied power as the insufficient power from the power company.
However, the basic charge of self-supplied power received from the power company is 10% higher than the basic charge of power by load factor (if the self-supplied power is not used, the basic charge of power by load factor is Is 30% of the increase of 10%), which is higher than normal contract power.
The contract of power by load factor is one of the types of contracts concluded with an electric power company. The content is that the power charge is discounted as the load factor of power (the rate of power used with respect to the maximum contract power) is improved. belongs to.
[0004]
[Problems to be solved by the invention]
In the contract with the power company, when receiving the supply of power together with the above-mentioned self-supplied power, the above contract maximum power is the contract power normally used and the self-supplied power (the power generation capacity of the self-generation facility). When the private power generation facility owned by itself is operated and self-supplied power is not used, the load factor is low and the power charge is set high.
On the other hand, when a standby power generation facility is installed that automatically switches and starts operation when the private power generation facility stops, the self-supplied power supply is calculated from the power generation capacity of the private power generation facility. Since the power generation capacity is subtracted, the load factor can be slightly improved. However, even if the standby power generation equipment is provided in the facility where the private power generation equipment is provided in this way, the standby power generation equipment is operated only when the private power generation equipment is stopped, and the operation frequency is extremely low, On the other hand, in spite of the low operation frequency, there are problems such as securing of installation space and an increase in equipment management costs and equipment costs, and the economic effect of performing private power generation is reduced.
Therefore, in view of the above circumstances, the present invention improves the economic effect of performing in-house power generation by securing in-house replenishment power at a low cost in facilities provided with such in-house power generation facilities. The purpose is to provide a self-supplied power consignment method and a power generation facility.

The operating means 14 is means for performing an operation process and operating the standby power generation facility based on the stop information received by the communication means 16. Further, the operating means 14 consumes the time interest of the facility that has received the stop information stored in the storage means 15 to operate the standby power generation facility 2, in other words, within the range of the time interest of the facility, The power generation facility 2 is operated to generate power.
[0022]
And the management apparatus 3 makes the power transmission means 4 work, performs an operation process, operates the standby power generation facility 2 by the operation means 15, and uses the power line owned by the power company 50 as self-supplied power. A power transmission step of transmitting power to the facility 30 that has transmitted the stop information to the communication means 16 by performing the reception step is performed via 20, and self-supplied self-supplied power is performed.
Furthermore, in order to transmit the self-supplied power to the facility 30 in this way, the management device 3 reports that the power transmission from the communication means 16 to the power company 50 via the communication line 40 is started, Further, the standby power generation facility is configured to generate the self-supplied power corresponding to the amount of use while monitoring the use amount of the self-supplied power of the facility 30 receiving the supply of self-supplied power through the communication line 40. It is possible to achieve the same amount of rules in power consignment and to save the consignment fee as much as possible.
[0023]
Next, an administrator entrusted by a plurality of facilities 30 to manage the power generation facility 1 has a fixed cost such as a management cost for the power generation facility 1, a management cost for the standby power generation facility 2, and a usage fee for the installation space, and the standby power generation. Fees calculated in consideration of fuel costs and proportional costs such as consignment costs when the equipment 2 is operated are charged to each facility 30. The charging method will be described below.
First, the management device 3 of the power generation facility 1 is provided with fee calculation means 12 for calculating a fee charged to each facility 30.
The fee calculation means 12 calculates a fee charged to each facility 30 every month, for example. Among the fees, the fee for the fixed cost is a management fee for the standby power generation facility 2 set in advance. Use a fee that takes into account. Then, the charge calculation unit 12 calculates the time during which the standby power generation facility 2 of each facility 30 is operated based on the remaining amount of time ownership of each facility 30 stored in the storage unit 15, and the time A charge obtained by multiplying the price in advance by a unit price considering the fuel cost is used as a charge for the proportional cost.
Then, the fee calculation means 12 stores the total of the charges for the fixed cost and the proportional cost in the charge data storage means 13 as a charge for charging each facility 30, and the administrator stores the charge data storage means 13. The fee is charged to each facility 30 based on the fee stored in the.
[0024]
In the self-supplied replenishment power consignment method and power generation facility described so far, the facility that consumes all of the time share in a predetermined period and wishes to consign the self-supplied replenishment power, supplies the self-supplied replenishment power from the power company. It is also possible to purchase the remaining amount of time interest from other facilities, and operate the standby power generation facility to self-deliver the power generated as self-supplied power.
[0025]
Furthermore, in facilities where the time interest remains for a predetermined period, the fee paid to the management company will be reduced by a proportional cost corresponding to the remaining amount. It is also possible to operate the power generation facility 2 and sell the generated power in other power markets to obtain profits.
