Description
本発明は、発電所などにおける海水を冷却水として利用する冷却システムの取水口と放水口における温度差が所定の温度以上とならないように海水温度の上昇を予測するためのシステムに関する。 The present invention relates to a system for predicting an increase in seawater temperature so that a temperature difference between a water intake port and a water discharge port of a cooling system that uses seawater as cooling water in a power plant or the like does not exceed a predetermined temperature.
従来より、発電所などでは、例えば、特許文献１に記載されているように、復水器冷却システムにより、取水口から海水を取り入れ、復水器における冷却水として利用した後、放水口から海に排出することにより復水器の冷却を行っている。このような設備における取水口と放水口との海水温度の差は、海水温度の上昇を防止すべく、公害防止協定により所定の協定値（例えば７℃）未満になるように定められている。 Conventionally, in a power plant, for example, as described in Patent Document 1, seawater is taken from a water intake by a condenser cooling system and used as cooling water in the condenser, and then the seawater is discharged from a water outlet. The condenser is cooled by discharging it to The difference in seawater temperature between the intake port and the discharge port in such facilities is determined to be less than a predetermined agreement value (for example, 7 ° C.) by a pollution prevention agreement in order to prevent an increase in seawater temperature.
このため、従来は、取水口及び放水口の近傍に温度計を設置し、取水口及び放水口の水温を監視し、取水口と放水口との水温の差が設定値（例えば、６．７℃）以上になると警報を発し、オペレータが循環ポンプの吐出流量を増加することや発電量を低減することにより放水口より排出される海水の水温を降下させて、温度差を低減していた。なお、例えば、特許文献１にはこのように吐出流量を調整可能なシステムが記載されている。
ところで、通常、取水口から取り入れられた海水が、復水器において冷却水として利用された後、放水口から海へ排出されるまでには時間がかかる（地理的条件や循環ポンプの駆動台数等により異なるが例えば２０〜６０分程度）。このため、取水口から取り入れられた海水が放水口から排出されるまでに上昇する温度が協定値を下回る場合であっても、海水が取水口から放水口まで到達する間に海水温度が急激に低下してしまうと、放水される時点で放水温度と海水温度との差が大きくなり、取水口と放水口との温度差が協定値を超えてしまう恐れがある。このことは、一時的に海水温が上昇し、その後、急激に低下した場合も同様である。 By the way, normally, it takes time for seawater taken from the intake port to be discharged as cooling water in the condenser and then discharged from the outlet to the sea (geographical conditions, number of circulating pumps driven, etc.) For example, about 20 to 60 minutes). For this reason, even if the temperature that rises before the seawater taken from the intake port is discharged from the discharge port is below the agreed value, the seawater temperature rapidly increases while the seawater reaches the discharge port from the intake port. If it falls, the difference between the water discharge temperature and the seawater temperature will increase at the time of water discharge, and the temperature difference between the water intake and the water discharge outlet may exceed the agreed value. The same applies to the case where the seawater temperature temporarily rises and then suddenly drops.
本発明は、上記の問題に鑑みなされたものであり、その目的は、海水温度の急激な温度変化を予め予測できるようにすることである。 The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to predict in advance a rapid temperature change in seawater temperature.
本発明の海水温度上昇予測システムは、海水の温度上昇を予測するシステムであって、予測の対象となる日を指定する日付情報を受け付ける入力受付手段と、前記日付情報により指定される日の潮位に関する潮位情報を取得する潮位情報取得手段と、海水の温度変化が生じる可能性の高い潮位に関する発生条件と、当該発生条件に該当する場合に温度上昇が発生する可能性の高い時間に関する時間条件とが対応付けられた温度変化条件情報が、１年間を複数に分割した各期間に対して記録された温度変化条件情報データベースと、 前記温度変化条件情報データベースを参照して、前記入力受付手段が取得した日付情報により指定される日付が該当する期間の前記温度変化条件情報を取得し、前記潮位情報が前記取得した温度変化条件情報に含まれる前記発生条件に該当するか否かを判定し、該当する場合には、前記発生条件と対応付けられた前記時間条件に基づき、温度上昇が発生する可能性の高い時間を求める予測部とを備えることを特徴とする。 The seawater temperature rise prediction system of the present invention is a system for predicting a temperature rise of seawater, input receiving means for receiving date information specifying a day to be predicted, and a tide level specified by the date information Tide level information acquisition means for acquiring tide level information regarding, occurrence conditions related to tide levels where seawater temperature changes are likely to occur, and time conditions related to times when temperature rise is likely to occur when the occurrence conditions are met Is obtained by the input receiving means with reference to the temperature change condition information database recorded for each period obtained by dividing one year into a plurality of periods, and the temperature change condition information database. The temperature change condition information for a period corresponding to the date specified by the acquired date information is acquired, and the tide level information is included in the acquired temperature change condition information. A prediction unit for determining a time at which a temperature rise is likely to occur based on the time condition associated with the generation condition ; It is characterized by providing.
また、本発明の海水温度上昇予測方法は、海水の温度変化が生じる可能性の高い潮位に関する発生条件と、当該発生条件に該当する場合に温度上昇が発生する可能性の高い時間に関する時間条件とが対応付けられた温度変化条件情報が、１年間を複数に分割した各期間に対して記録された温度変化条件情報データベースを備えたコンピュータにより、海水の温度上昇を予測する方法であって、前記コンピュータが、予測の対象となる日を指定する日付情報を受け付けるステップと、前記コンピュータが、前記日付情報により指定される日の潮位に関する潮位情報を取得するステップと、前記コンピュータが、前記温度変化条件情報データベースを参照して、前記受け付けた日付情報により指定される日付が該当する期間の前記温度変化条件情報を取得し、前記潮位情報が前記取得した温度変化条件情報に含まれる前記発生条件に該当するか否かを判定し、該当する場合には、前記発生条件と対応付けられた前記時間条件に基づき、温度上昇が発生する可能性の高い時間を求めるステップと、を備えることを特徴とする。 In addition, the seawater temperature rise prediction method of the present invention includes a generation condition related to a tide level where a change in seawater temperature is likely to occur, and a time condition related to a time during which a temperature increase is likely to occur when the generation condition is met. Is a method for predicting the temperature rise of seawater by a computer having a temperature change condition information database recorded for each period obtained by dividing one year into a plurality of periods. A step of receiving date information designating a date to be predicted; a step of obtaining information on a tide level related to a tide level designated by the date information; and a step of calculating the temperature change condition. by referring to the information database, the change in temperature condition information period date specified falls by the accepted date information And determining whether or not the tide level information corresponds to the generation condition included in the acquired temperature change condition information, and if so, based on the time condition associated with the generation condition And a step of obtaining a time when the temperature rise is likely to occur .
本発明によれば、予測の対象となる日の潮位に関する情報に基づき、海水温度の急激な変化の発生する確率の高い時期を予測することができるため、オペレータは予めこの情報に基づき、発電量を低減するなどの対応をすることができ、取水口と放水口との海水温度の上昇が協定値未満に保つことができる。 According to the present invention, since it is possible to predict a time when there is a high probability that an abrupt change in seawater temperature will occur based on information on the tide level of the day to be predicted, the operator can generate power generation based on this information in advance. The rise in seawater temperature at the intake and outlet can be kept below the agreed value.
以下、本発明の循環ポンプにおける海水温度上昇予測システムの一実施形態を図面を参照しながら説明する。
図１は、発電所における復水器の冷却システム１０の構成を示す図である。同図に示すように、復水器冷却システム１０は、海中に設けられた取水口１２から循環ポンプ１１により海水を取り入れ、復水器１３における冷却水として利用した後、海中に設けられた放水口１４より海に排出するシステムである。
Hereinafter, an embodiment of a seawater temperature rise prediction system for a circulation pump according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a condenser cooling system 10 in a power plant. As shown in the figure, the condenser cooling system 10 takes in seawater from a water intake 12 provided in the sea by a circulation pump 11 and uses it as cooling water in the condenser 13, and then releases the water provided in the sea. It is a system that discharges water from the water inlet 14 to the sea.
循環ポンプ１１は、吐出流量が調整可能なポンプである。吐出流量が調整可能なポンプとしては、例えば、立軸可動翼循環ポンプなどを用いてもよいし、複数のポンプを並列接続し、ポンプの可動台数を変更することにより吐出量を調整可能に構成してもよい。なお、立軸可動翼循環ポンプは回転軸に動翼が取り付けられており、動翼が回転することにより海水を吸い上げて吐出し、この動翼の開度を変化させることにより、吐出流量を調整可能なポンプである。 The circulation pump 11 is a pump whose discharge flow rate can be adjusted. As a pump whose discharge flow rate can be adjusted, for example, a vertical axis movable blade circulation pump or the like may be used, or a plurality of pumps are connected in parallel, and the discharge amount can be adjusted by changing the number of movable pumps. May be. The vertical axis movable blade circulation pump has a rotating blade attached to the rotating shaft, and the rotating blade sucks up and discharges seawater, and the discharge flow rate can be adjusted by changing the opening of the moving blade. It is a simple pump.
取水口１２から取り入れられた海水が、復水器１３を通って、放水口１４から海へ排出されるまでには、地理的条件や循環ポンプ１１の駆動状況により異なるが２０〜６０分程度かかる。また、復水器１３で冷却水として利用された海水が放水口１４に到達するまでには、１０〜２０分程度かかる。 It takes about 20 to 60 minutes for the seawater taken from the intake 12 to pass through the condenser 13 and be discharged from the outlet 14 to the sea, depending on geographical conditions and the driving condition of the circulation pump 11. . Further, it takes about 10 to 20 minutes for the seawater used as cooling water in the condenser 13 to reach the water outlet 14.
ここで、従来技術の欄に記載したように、取水口１２から取り入れられた海水が放水口１４から排出されるまでに海水温度が急激に変化してしまうと、取水口１２と放水口１４との温度差が協定値（例えば７℃）を超えてしまう恐れがある。また、発電量を低減することにより、復水器１３での温度上昇を抑えることも考えられるが、復水器１３を通過した海水が放水口１４に到達するまでに、例えば、１０〜２０分程度の時間がかかるため、発電量の低減が放水温度の低下に反映されるまで時間がかかり、その間に温度差が協定値を超える恐れがある。従って、予め、海水温度の急激な変化を予測する必要がある。 Here, as described in the column of the prior art, if the seawater temperature changes abruptly before the seawater taken from the water intake 12 is discharged from the water outlet 14, the water intake 12 and the water outlet 14 The temperature difference may exceed the agreed value (for example, 7 ° C.). In addition, it is conceivable to suppress the temperature rise in the condenser 13 by reducing the power generation amount, but for example, 10 to 20 minutes until the seawater that has passed through the condenser 13 reaches the water outlet 14. Since it takes a certain amount of time, it takes time until the reduction in the amount of power generation is reflected in the decrease in the discharge temperature, during which the temperature difference may exceed the agreed value. Therefore, it is necessary to predict a rapid change in seawater temperature in advance.
そこで、発明者らは、海水温度が急激に変化する原因を特定するため、海水温度が急激に変化した日の潮位及び降水量を測定した。
図２は、海水温度が急激に変化した際の降水量を示す表である。同図に示すように、海水の温度の急激な変化が生じた際に、雨天であった場合は非常に少ない。このことから、降水量と海水の温度の急激な上昇とは相関がないことが確認された。
Therefore, the inventors measured the tide level and precipitation on the day when the seawater temperature changed abruptly in order to identify the cause of the seawater temperature changing rapidly.
FIG. 2 is a table showing precipitation when the seawater temperature changes abruptly. As shown in the figure, when there is a sudden change in the temperature of the seawater, there are very few cases where it was raining. From this, it was confirmed that there was no correlation between precipitation and rapid rise in seawater temperature.
また、図３は、各月における、急激な温度変化（３０分間以内に０．３℃以上の変化）の発生件数と、急激な温度変化が生じた際に干満差が２ｍ以上であった件数及びその割合、干満差が１．５ｍ以下であった件数及びその割合、急激な温度変化の発生時の潮位が２ｍ以上であった件数及びその割合、発生時潮位が１ｍ以下であった件数及びその割合、満潮前後１時間以内に急激な温度変化が生じた件数及びその割合、干潮前後１時間以内に急激な温度変化が生じた件数及びその割合を示す表である。 In addition, Figure 3 shows the number of occurrences of rapid temperature changes (changes of 0.3 ° C or more within 30 minutes) and the number of tidal differences of 2 meters or more when sudden temperature changes occur. And the ratio, the number of cases where the tidal difference was 1.5 m or less, the ratio, the number of cases where the tide level was 2 m or more at the time of sudden temperature change and the ratio, the number of cases where the tide level was 1 m or less and It is a table | surface which shows the ratio, the number of the cases where the rapid temperature change occurred within 1 hour before and after the high tide, and the ratio, the number of the cases where the rapid temperature change occurred within 1 hour before and after the low tide, and the ratio.
同図に示すように、春季（４月〜６月）では、急激な温度変化が生じた際に、干満差が２ｍ以上である確率が５０％を超えており、干満差が２ｍ以上となる場合に急激な温度変化が生じる可能性が高いことがわかる。また、該当する期間の急激な温度変化が生じた状況を確認したところ、多くの場合、潮位の変動中であった。 As shown in the figure, in spring (April to June), when a sudden temperature change occurs, the probability that the tidal difference is 2 m or more exceeds 50%, and the tidal difference becomes 2 m or more. It can be seen that there is a high possibility that a sudden temperature change occurs. Moreover, when the situation where the rapid temperature change occurred in the corresponding period was confirmed, in many cases, the tide level was changing.
また、夏季（７月〜９月）では、急激な温度変化が生じた際の潮位が２ｍ以上であった割合が５０％を超えており、比較的潮位の高いときに、急激な温度変化が生じる可能性が高いことがわかる。また、該当する期間の急激な温度変化が生じた状況を確認したところ、多くの場合、潮位の変動中であった。 In summer (July to September), the ratio of the tide level when the rapid temperature change occurred was 2m or more exceeded 50%, and when the tide level was relatively high, the rapid temperature change It can be seen that this is likely to occur. Moreover, when the situation where the rapid temperature change occurred in the corresponding period was confirmed, in many cases, the tide level was changing.
また、秋季（１０月〜１２月）では、潮位との関係は見られないが、急激な温度変化の発生時が干潮の前後１時間以内である割合が５０％を超えており、干潮の前後１時間以内に、急激な温度変化が生じる可能性が高いことがわかる。 In autumn (October to December), there is no relationship with the tide level, but the rate of sudden temperature changes within one hour before and after the low tide is over 50%. It can be seen that there is a high possibility that a rapid temperature change occurs within one hour.
また、冬季（１月〜３月）では、急激な温度変化の発生時が、干満差が１．５ｍ以下である割合が５０％を超えており、干満差が１．５ｍ以下である場合に、急激な温度変化が生じる可能性が高いことがわかる。また、該当する期間の急激な温度変化が生じた状況を確認したところ、多くの場合、潮位の変動中であった。 In winter (January to March), when a sudden temperature change occurs, the ratio of the tidal difference is 1.5m or less exceeds 50%, and the tidal difference is 1.5m or less. It can be seen that there is a high possibility of sudden temperature changes. Moreover, when the situation where the rapid temperature change occurred in the corresponding period was confirmed, in many cases, the tide level was changing.
本願発明者らは、上記の実験結果に鑑みて、以下に説明するような、干満潮に関する情報に基づき急激な海水温度の変化の発生を予測し、警報を発する温度上昇予測システムを構成した。 In view of the experimental results described above, the inventors of the present invention configured a temperature rise prediction system that predicts the occurrence of a sudden change in seawater temperature based on information related to tidal tide as described below and issues an alarm.
図４は、本実施形態の温度上昇予測システム２０の構成を示す図である。同図に示すように、温度上昇予測システム２０は、例えば、コンピュータなどにより構成され、入力受付部２１と、温度変化予測部２２と、温度変化条件データベース２４と、警報部２３とを備える。なお、温度変化条件データベース２４はハードディスク等の記録媒体により構成され、また、各構成部はＣＰＵがプログラムを実行することにより実現される。 FIG. 4 is a diagram showing a configuration of the temperature rise prediction system 20 of the present embodiment. As shown in the figure, the temperature rise prediction system 20 is configured by, for example, a computer, and includes an input receiving unit 21, a temperature change prediction unit 22, a temperature change condition database 24, and an alarm unit 23. The temperature change condition database 24 is configured by a recording medium such as a hard disk, and each component is realized by the CPU executing a program.
入力受付部２１は、予測の対象となる日付に関する日付情報と、その日の干潮、満潮時刻及びその潮位に関する潮位情報の入力を受け付ける。なお、潮位情報については、例えば、気象庁のホームページなどから取得することができる。 The input receiving unit 21 receives input of date information related to a prediction target date, and low tide, high tide time and tide level information regarding the tide level of the day. The tide level information can be acquired from, for example, the homepage of the Japan Meteorological Agency.
図５は、温度変化条件データベース２４に記録された情報の構成を示す図である。温度変化条件データベース２４には、上述した海水温度に急激な上昇があった際の潮位の測定結果から得られた、各季節に対する急激な温度上昇が発生しやすい条件（以下、発生条件という）と、この発生条件を満たした場合に急激な温度上昇が発生する可能性の高い時間帯（以下、発生時間帯という）に関する温度変化条件情報が記録されている。すなわち、図５に示すように、春季（４月〜６月）に対しては、発生条件として「干満差が２ｍ以上」、発生時間帯として「潮位変動中」が、夏季（７月〜９月）に対しては、発生条件として「潮位変動が２ｍ以上」、発生時間帯として「潮位変動中」が、秋季（１０月〜１２月）に対しては、発生条件は特になく、発生時間帯として「干潮前後１時間内」が、冬季（１月〜３月）に対しては、発生条件として「干満の差が１．５ｍ以下」、発生時間帯として「潮位変動中」が記録されている。 FIG. 5 is a diagram showing a configuration of information recorded in the temperature change condition database 24. The temperature change condition database 24 includes conditions (hereinafter referred to as occurrence conditions) that are likely to cause a rapid temperature rise for each season, obtained from the measurement result of the tide level when the seawater temperature has risen rapidly. Temperature change condition information related to a time zone (hereinafter referred to as the occurrence time zone) in which a rapid temperature increase is likely to occur when this generation condition is satisfied is recorded. That is, as shown in FIG. 5, in the spring season (April to June), the occurrence condition is “tidal difference is 2 m or more”, and the occurrence time zone is “tidal level fluctuation” in summer (July to 9 For the moon), the occurrence condition is “tidal fluctuation of 2m or more” and the occurrence time zone is “tidal fluctuation”, but for the fall season (October to December), there is no particular occurrence condition, and the occurrence time “Within 1 hour before and after low tide” is recorded as the obi, and during winter (January to March), “difference in tidal range is 1.5 m or less” and “currently changing tide” is recorded as the occurrence time zone. ing.
温度変化予測部２２は、入力受付部２１が入力を受け付けた日付情報に基づき、温度変化条件データベース２４を参照して予測の対象となる日が該当する季節に対応する温度変化条件情報を取得する。そして、潮位情報における干満潮時の潮位等の条件が発生条件に該当するか否かを判定し、該当する場合には発生時間帯に基づき、予測の対象となる日における急激な温度上昇が発生する可能性が高い時間帯に関する温度上昇発生情報を作成する。 The temperature change prediction unit 22 refers to the temperature change condition database 24 based on the date information received by the input receiving unit 21 and acquires temperature change condition information corresponding to the season corresponding to the day to be predicted. . Then, it is determined whether the conditions such as the tide level at the tidal level in the tide level information correspond to the occurrence condition, and if so, based on the occurrence time zone, a rapid temperature rise occurs on the day to be predicted Create temperature rise occurrence information related to time zones where there is a high possibility of
警報部２３は、温度変化予測部２２が作成した温度上昇発生情報に基づき、急激な温度上昇が発生する可能性が高い時間帯の所定の時間前になると、その旨を例えば、画面表示などにより警告する。そして、急激な温度上昇が発生する可能性が高い時間帯が経過した後、警告を終了する。 Based on the temperature rise occurrence information created by the temperature change prediction unit 22, the alarm unit 23 notifies that fact by a screen display or the like when a predetermined time before the time zone where a rapid temperature rise is likely to occur. Warning. Then, the warning is terminated after a time period in which a rapid temperature increase is likely to occur.
オペレータは、このような警告により、急激な温度上昇が発生する可能性が高い期間に入ることを認識すると、予め、発電量を低減することにより冷却水の取水口１２と放水口１４との間の温度上昇を抑えておく。これにより、海水温度が急激に上昇したとしても、復水器１３における温度上昇が抑えられているため、結果として取水口１２と放水口１４との間の温度差が協定値を超えることを防止できる。 When the operator recognizes that a period in which there is a high possibility that a rapid temperature rise will occur due to such a warning, the operator reduces the power generation amount in advance to reduce the gap between the cooling water intake 12 and the water outlet 14. Keep the temperature rise of Thereby, even if seawater temperature rises rapidly, since the temperature rise in the condenser 13 is suppressed, as a result, the temperature difference between the water intake 12 and the water outlet 14 is prevented from exceeding the agreed value. it can.
以上説明したように、本実施形態によれば、予め測定結果に基づき作成された、季節ごとの急激な温度上昇が生じ易い干潮又は満潮時の潮位等に関する期間情報と、当日の潮位情報とに基づき、急激な温度上昇が発生しやすい期間を予測することができる。このため、急激な温度上昇が生じる前に、予め、発電量を低減し、取水口と放水口との間の温度上昇を抑えることができ、放水口から放出される海水が協定値を超過するのを防止できる。 As described above, according to the present embodiment, the period information related to the tide level at low tide or high tide, which is likely to cause a rapid temperature increase for each season, and the tide level information for the day, which are created based on the measurement results in advance. Based on this, it is possible to predict a period during which a rapid temperature increase is likely to occur. For this reason, before a sudden temperature rise occurs, the amount of power generation can be reduced in advance, and the temperature rise between the water intake and the water outlet can be suppressed, and the seawater discharged from the water outlet exceeds the agreed value. Can be prevented.
なお、本実施形態では、温度変化条件データベース２４に季節ごとの温度変化条件を記録するものとしたが、これに限らず、例えば、月ごとに温度変化条件が異なる場合には、各月の温度変化条件を記録してもよく、また、１年間を通しての温度変化条件が略一定である場合には、期間ごとに分けずに一定の温度変化条件を記録してもよい。 In the present embodiment, the temperature change condition for each season is recorded in the temperature change condition database 24. However, the present invention is not limited to this. For example, when the temperature change condition varies from month to month, the temperature of each month The change condition may be recorded, and if the temperature change condition throughout the year is substantially constant, the constant temperature change condition may be recorded without dividing the period.
また、本実施形態では、入力受付部２１により予測の対象となる日の干潮、満潮の時刻及びその潮位に関する潮位情報を受け付けることとしたが、温度上昇予測システム２０に、予め潮位情報が記録されたデータベースを設けておき、このデータベースを参照することとしてもよい。 Further, in the present embodiment, the input reception unit 21 receives the low tide of the day to be predicted, the time of high tide and the tide level information related to the tide level, but the tide level information is recorded in the temperature rise prediction system 20 in advance. It is also possible to provide a separate database and refer to this database.
