  The automatic calculation of the contracted gradient method and hydroelectric power station group daily power generation planning method described in Japanese Patent Application Laid-Open No. 2006-39838 does not always provide the optimum solution desired by the operation plan creator. For this reason, manual calculation to create a plan by manually operating a computer is required in the creation of an operation plan for a connected water system.

  By the way, in an articulated water system having a plurality of dams and power plants, the discharge of the upstream dam affects the downstream dam with a flow-down delay. For this reason, in the manual calculation, it is necessary to modify and take into account the downstream dam operation plan when creating the upstream dam operation plan.

  Next, an operation plan creation procedure of the operation plan creation support system according to the present embodiment will be described.

  FIG. 4 is a flowchart showing details of the operation plan creation in the connected water system operation plan creation support system of FIG. 1. The operation plan creation flowchart is shown in FIG. 1 and FIG. 7 with the computer 30, the first display device 10 and the second display. Each is associated with the display device 20.

  First, in step 110 for selecting a planning target date screen in the operational plan creation flowchart, a planning target date screen is selected in step 111 of the current day planning screen OR the next day planning screen.

  If the current day plan screen is selected in step 111 of the current day plan screen OR next day plan screen, the process proceeds to step 115 for acquiring actual data, and data in the actual result database 33 stored in the computer 30 is acquired.

  Further, when the next day plan screen is selected in step 111 of the current day plan screen OR next day plan screen, or after the step 115 for obtaining actual data, the process proceeds to the step 112 for obtaining plan and provisional plan data, and the computer 30 The plan data and provisional plan data of the plan database 32 and the provisional plan database 31 stored in FIG.

  Next, in step 111 of the current day plan screen OR next day plan screen, the current day plan screen is selected, or the next day plan screen is selected. However, in either case, the process proceeds to step 114 for acquiring equipment data and the like and is stored in the computer 30. The data is acquired from the existing equipment data 34.

  In either case of selecting the current day plan screen or the next day plan screen, the computer 30 calculates the plan and the temporary plan. Although details will be described later, in the calculation of the plan, the plan water level value is calculated by the plan calculation means 30a of the computer 30, and in the temporary plan calculation, the temporary plan water level value is calculated by the temporary plan calculation means 30b of the computer 30 and displayed second. It will be displayed on the device 20.

  Based on the various data acquired from the databases 31 to 34, the process proceeds to step 120 for displaying a default screen (planning screen) and defaults, and then proceeds to step 120 for selecting a plan thereafter.

  In the plan selection step 120, the screen of the plan and the temporary plan is displayed on the first display device 10, and either the plan or the temporary plan is selected in the step 121 of the next temporary plan OR plan.

  The difference between the plan screen and the temporary plan screen displayed on the first display device 10 in the plan selection step 120 is that the screen shown in the first display device 10 is operated by selecting reference numeral 1 to select the plan and the temporary plan. Thus, the plan data is displayed when the plan is selected, and the temporary plan data is displayed when the temporary plan is selected. However, data such as power generation output cannot be entered on the planning screen.

  On the other hand, the second display device 20 has a plan water level, a provisional plan water level, a water level upper limit, a water level lower limit, an actual water level (the next day's plan (No display in case) is displayed.

The temporary plan and the plan are selected by operating the reference numeral 1 of the first display device 10 shown in FIG. Here, when a plan is selected, the process proceeds to step 123 for prohibiting input of power generation output and the like, and the power generation plan of the power generation plan at each power plant is indicated in the vertical axis column indicated by reference numeral 4 of the first display device 10 shown in FIG. Inputs such as output (MW) and discharge flow (m ³ / s) of discharge plan in each dam are prohibited.

When the temporary plan is selected, the process proceeds to step 122 for permitting input of power generation output, etc., and is indicated by reference numeral 4 of the first display device 10 shown in FIG. In the vertical axis column, the operator inputs data such as the power generation output (MW) of the power generation plan at each power plant and the discharge flow rate (m ³ / s) of the discharge plan at each dam.

  Next, the process proceeds to step 131 for recalculating the water level of the temporary plan, and the power generation output, discharge flow rate, and water level data by the operator from the screen, which is the input means provided in the first display device 10 in step 130 for inputting the power generation output and the like Based on the input, the temporary plan water level is recalculated by the temporary plan calculation means 30b of the computer 30.

  By the operator's return pressing operation (line feed operation) after inputting the data on the screen of the first display device 10, for example, the power generation output of the power plant that is the data input by the operator is related to the The water level is recalculated, and then the process proceeds to step 132 for saving the temporary plan, and the temporary plan is stored in the temporary plan database 31.

  Further, the recalculation result by the computer 30 displays the temporary plan stored in the screen display step 133 on the screens of the first display device 10 and the second display device 20.

  Thereafter, the process proceeds to step 140 for confirmation by the operator, and the temporary plan calculation means 30b of the computer 30 recalculates and operates on the temporary plan data displayed on the screens of the first display device 10 and the second display device 20. If the administrator determines that the plan is satisfactory, the process proceeds to step 150 where the registration button is pressed, and the operator operates the registration button to proceed to step 151 where the temporary plan data is copied to the plan data. The plan data is saved as plan data stored in the plan database 32 of the computer 30.

  On the other hand, in step 140 for confirmation of the operator, the operator recalculates the temporary plan calculation means 30b of the computer 30 and displays the temporary plan data displayed on the screen of the first display device 10 or the second display device 20 by the operator. If it is determined that the plan is not satisfied and needs to be corrected, the process proceeds to step 160 for returning to the original state, and again proceeds to step 130 for inputting power generation output and the like, and the above steps are repeated.

  That is, in step 140 of the operator's confirmation, the operator again inputs data such as the power generation output into the vertical axis column indicated by reference numeral 4 of the first display device 10 shown in FIG. Thirty temporary plan calculation means 30b calculate again and create a new temporary plan.

  However, if the operator wants to return to the original plan by looking at the temporary plan data displayed on the screen of the first display device 10, the process proceeds to step 170 for pressing the cancel button through the step 160 for returning to the original plan. The plan previously registered by the computer 30 can be displayed by pressing the cancel button by the operator.

  That is, the program proceeds to step 171 for copying the plan data to temporary plan data, and based on the copied plan data, the program proceeds to step 130 for inputting power generation output and the like, and the above-described steps are repeated.

  FIG. 5 schematically shows a water system diagram of an articulated water system Z that is an object of the present invention. A dam C is connected downstream of the dam A, and a dam D is connected downstream of the dam C. Further, water also flows from dam B and is connected to dam C. In the figure, broken arrows flowing into each dam represent natural flow rates.

  Regarding the flow delay between dams, the flow between dam A to dam C, dam B to dam C, and dam C to dam D is 1 hour.

  The dam A, dam B, dam C, and dam D are provided with a power plant A, a power plant B, a power plant C, and a power plant D, respectively, and generate power generation at these power plants. It is like that.

  FIG. 6 shows the water level curve, the water level upper limit, and the water level lower limit in the power generation plan of the connected water system Z shown in FIG. 5 and the temporary plans related to the dam A, dam B, dam C, and dam D belonging to the connected water system.

  FIG. 5 and FIG. 6 show an example of a method for correcting / considering a temporary plan of an operation plan executed by an operator. Here, the final water level of the operation plan is fixed, and the temporary plan of the operation plan is revised. In other words, the deviation from the water level of the dam is eliminated by changing the discharge time zone without changing the discharge flow from the dam of the day.

  The water level graph shown in FIG. 6 shows a situation where the water level of the dam C has become lower than the water level lower limit. In this case, any one of the following three methods may be employed as a method of eliminating the dam C water level lower limit deviation.

  The first method considers the flow delay between the dams shown in Fig. 5 and releases it from the power plant A installed in the dam A upstream of the dam C in the time zone after the dam C water level departure time. This is a method of moving the flow rate to a time zone before the water level departure time of dam C. For example, the power generation output of 5.0 MW planned by the power plant A from 24:00 to 24:00 is moved from 13:00 to 15:00, and 13:00 Is set to 5.0 MW, and 14 to 15:00 is set to about 13.0 MW, so that the water level lower limit deviation of dam C is eliminated.

  The second method is based on the discharge from the power plant B installed in the dam B upstream of the dam C in the time zone after the deviance of the dam C It is a method of moving to a time zone before the time, for example, each 3.0 MW power generation output planned for 22:00 to 24:00 of power plant B is moved to 13:00 to 15:00, and 13.0 to 15:00 is about 6.0 MW each This eliminates the water level lower limit deviation of dam C.

  The third method is to move the discharge flow in the time zone before the water level departure time of dam C to the time zone after the water level departure time, which is planned at 13:00 to 16:00 of the power plant C installed in the dam C. Reduce the generated power output and move to the time zone from 17:00 to 24:00. For example, the deviation of the water level lower limit of the dam C is eliminated by setting the power generation output from 13:00 to 16:00 to about 7.0 MW and the power generation output from 17:00 to 21:00 to about 6.5 MW each.

  By the way, if only one dam water level graph is displayed as a dam water level graph, the operator confirms the operation plan of each dam and considers which of the above three methods is appropriate. It is necessary to confirm the operation plan of each dam.

  On the other hand, in the operation plan creation method in the connected water system operation plan creation support system of the present embodiment described above, the operator can confirm the water levels of the dams A to D at the same time. Even if the water level deviation of dam C can be eliminated by the eye method, it is possible to easily predict and verify that deviations occur in dam B and dam D.

  In the present embodiment described above, the operator can predict and verify that the water level of the dam A does not deviate by the first method, for example.

  In addition to the above three methods, the morning discharge of dam D is moved in the afternoon to make room for the lower limit of dam D's water level, and the discharge of dam C's water level lower limit deviation time zone is A method of moving to a time zone can also be easily considered.

  Thus, an appropriate power generation operation plan can be created more easily by providing means for creating a plan while simultaneously confirming the operation plans of a plurality of dams and power plants related to the connected water system.

  In the connected water system operation plan creation support system of the above-described embodiment, the recalculation of the water level of the desired dam and other affected dams is performed by manual calculation by pressing the return after inputting data on the desired dam. can do. In other words, it is possible to recalculate the plan creation only by operating the keyboard directly connected to the computer. This makes it possible to perform recalculation from the input of the power generation output or discharge flow to the water level without being interrupted by, for example, a mouse movement operation.

  In addition, in the connected water system operation plan creation support system of the present embodiment, the function of saving the revised plan (provisional plan) as a plan by registering it in the computer and the plan registered last time by canceling the revised plan. It has a display function, and even when the operator fails to make corrections, it is possible to make corrections any number of times based on the previous plan until an optimal plan (provisional plan) is obtained.

  Therefore, according to the present embodiment, it becomes easy to create an operation plan for a connected water system, which is a daily work of the operator, and the load on the operator can be reduced.

  In addition, in the connected water system operation plan creation support system of this embodiment, an appropriate power generation operation plan can be easily created by creating a plan while simultaneously confirming the operation plans of a plurality of dams and power plants related to the connected water system. Can be created by manual calculation.

  By displaying the water levels of a plurality of dams on the display device, it is considered that the range for displaying the water level of one dam is narrowed, making it difficult to identify the water level curve. With the operation plan creation support system, the operator can easily create a water level curve by providing a function for enlarging and displaying the water level curve, changing the color of each water level curve, and displaying and hiding the water level curve all at once using check boxes. To be able to grasp.

  As is clear from the above, according to the present embodiment, an appropriate operation plan for each dam and power plant can be manually calculated while simultaneously confirming operation plans for a plurality of dams and power plants related to the connected water system. It is possible to realize a connected water system operation plan creation support system that can be easily created and reduce the load on the operator.

Means for confirming the water level curve of the tentative planned water level of the plurality of dams calculated by the computer and displayed on the second display device, and based on the confirmation means, the input means generates power from the desired dam and power plant. The recalculation result of the tentative design water level of the other dam is calculated by executing the recalculation of the tentative design water level of the other dam that has a relationship with the desired dam by inputting the output and discharge flow. Is displayed on the second display device, and the recalculation result of the provisional planned water level of the other dam is stored in the plan database . In the connected water system operation plan creation support system according to claim 1, in the same day plan of the power plant and dam, the power generation output and the discharge flow after the current time of the temporary plan of the day are input from the input means provided in the first display device. Based on the power generation output, discharge flow rate and water level input up to the current time, the computer calculates the tentative planned water level for the day, and the calculation result is displayed on the second display device as the actual water level curve and plan. The water level curve and the temporary plan water level curve are classified and displayed in color, and in the next day plan of the power plant and dam, the power generation output and discharge flow of the next day temporary plan are input from the input means, and this input data is run the calculation of the next day provisional planning level based on the computer by being configured to display the color change classifying the water level of the calculation result to the second display device in the planning level curve and the temporary plan level curve Operational planning support system of the connecting water systems and butterflies. In the connected water system operation plan creation support system according to claim 1, when the temporary plan is canceled, the data of the plan previously registered by the computer is called from the plan database and displayed on the first display device and the second display device. An operation plan creation support system for a connected water system, characterized in that when the created temporary plan is registered, the computer stores the plan data as plan data in the plan database .
