In addition, facilities relating to control of water distribution including water supply stations etc. are appropriately provided between each of the water purification plants 53-1 or 53-2 and each of the demand points 55-1 to 55-4. In the example shown in FIG. 1, two facilities, water supply stations 54-1 and 54-2, are provided. In the example of the water distribution network 50, the water purification plant 53-1 or 53-2 or the water supply station 54-1 or 54-2 has a state of water distribution such as a pump station or a valve composed of an arbitrary number of pumps. Assume that equipment to be changed is provided.

In the following embodiments and the like, it is assumed that the pump station is a facility constituted by an arbitrary number of pumps. The number and type of pumps at the pump station are not particularly limited. Alternatively, the pump station may consist of a single pump.

In the water distribution network 50, the setting in the facility such as the water purification plant 53-1 or 53-2, the water supply station 54-1 or 54-2 is set as a setting value related to operation according to the demand for water at each of the demand points 55 or the like.

The operation of the water distribution network 50 based on the established water distribution plan is performed by, for example, the water distribution operation system 10 shown in FIG. For example, the water distribution operation system 10 controls the water distribution of the water distribution network 50. The water distribution operation system 10 may have a configuration for developing a water distribution plan.

First, an embodiment of the present invention will be described. FIG. 2 is a diagram showing an operation support system according to the embodiment of the present invention.

As shown in FIG. 2, the operation support system 100 according to the embodiment of the present invention includes a deviation calculation unit 110, a water distribution range estimation unit 120, and a correction policy derivation unit 130. The divergence calculation unit 110 obtains a difference between the plan and the actual result regarding the water distribution state in the water distribution network. The water distribution range estimation unit 120 estimates, for each of the plan and the actual results, the relationship regarding the water distribution between the facilities provided in the water distribution network and the demand points based on the plans and the actual results regarding the state of the water distribution. The correction policy deriving unit 130 derives a correction policy for the equipment whose operation is to be corrected and the operation of the equipment based on the difference and the relationship.

Note that the operation support system 100 may further include a configuration for acquiring data used in the above-described components. FIG. 3 shows an example of the operation support system 100 in this case. As illustrated in FIG. 3, the operation support system 100 includes a water distribution network information acquisition unit 151, a water distribution plan acquisition unit 152, and a performance value acquisition unit 153.

The distribution network information acquisition unit 151 acquires setting values related to the operation of the distribution network and information related to the configuration of the distribution network 50. The water distribution plan acquisition unit 152 acquires a water distribution plan in the water distribution network. The actual value acquisition part 153 acquires the actual value which shows the operation state of the installation containing the pump etc. in a water distribution network. The actual value acquisition unit 153 acquires the actual value from the water distribution operation system 10 that operates the distribution network via a communication network or the like.

Subsequently, each component of the operation support system 100 in this embodiment will be described. First, components related to data acquisition of the operation support system 100 will be described.

The distribution network information acquisition unit 151 acquires setting values related to the operation of the distribution network and information related to the configuration of the distribution network 50. As described above, the set value includes the demand at each of the demand points 55 included in the distribution network 50 and the prediction thereof, the upper and lower limit values in operation at each of the facilities provided in the distribution network 50, and the like.

Moreover, the water distribution network information acquisition part 151 acquires the information regarding the structure of the water distribution network 50 other than a setting value. The distribution network 50 includes the connection relationship between the pipes 56, the connection relationship between the water purification plant 53, the water supply station 54, and the demand point 55, the pump station provided at the water purification plant 53, the water supply station 54, and the like. Includes equipment layout. Information regarding the performance of these facilities, such as the characteristics of the pumps and valves described above, may be included in the information representing the configuration of the water distribution network 50.

The water distribution network information acquisition unit 151 acquires the above-described information via any input means such as a keyboard, a mouse, a touch panel, a communication network, or the like. The operation setting value acquired by the water distribution network information acquisition unit 151 may be used in the water distribution operation system 10.

The water distribution plan acquisition unit 152 acquires a water distribution plan in the water distribution network. As described above, the water distribution plan is a plan related to the operation of facilities in the water distribution network 50, which is determined based on operation setting values and the like.

The water distribution plan acquisition unit 152 may have a mechanism for formulating a water distribution plan, and the mechanism may acquire the water distribution plan by formulating the water distribution plan. Moreover, the water distribution plan acquisition part 152 may acquire the water distribution plan formulated in the water distribution operation system 10, other systems, etc. via a communication network etc. When the water distribution plan acquisition unit 152 has a mechanism for determining a water distribution plan, the determined water distribution plan may be appropriately notified to the water distribution operation system 10. In addition, the water distribution plan acquisition part 152 acquires a water distribution plan suitably, for example whenever it derives | leads-out a correction policy, for example.

The water distribution plan is obtained based on the set value for each facility and information indicating the configuration of the water distribution network 50. That is, the water distribution plan is required so that the set values for each of the facilities are satisfied.

In this embodiment, the water distribution plan acquisition unit 152 mainly serves as a water distribution plan, the amount of water per unit period in each of the pipes 56 of the water distribution network 50, the operation procedure of the pump station provided in the water distribution network 50, and the operation of valves. Get procedures etc.

The operation method of the pump station determined in the water distribution plan includes, for example, the operating hours of the pump station, the number of operating pumps, the combination of pumps to be operated, the number of rotations, etc. Is included. In addition to this, designation of parameters relating to equipment such as valves provided in the water distribution network 50 may be included in the water distribution plan. In addition, the water distribution plan which the water distribution plan acquisition part 152 acquires in this embodiment is not restricted to said example.

The water distribution plan is preferably determined to be a plan optimized based on an arbitrary index. For example, among the water distribution plans that satisfy the set value, the water distribution plan is required so that the amount of power consumption in a certain period of equipment in the water distribution network 50 is minimized. For example, when a pump station provided in the water distribution network 50 is operated along the water distribution plan, the water distribution plan is required so that the amount of power consumed in the pump station during a certain period is reduced.

It should be noted that the above-mentioned certain period is appropriately determined according to the demand of the water distribution network 50 and the operation status. Further, when the water distribution plan acquisition unit 152 has a mechanism for formulating a water distribution plan, any known method is appropriately used as a specific method for formulating the water distribution plan.

The actual value acquisition unit 153 acquires actual values related to the operation of facilities including pumps in the water distribution network. The actual value acquisition part 153 acquires the actual value regarding the operation state of the facility in a water distribution network from the water distribution operation system 10 etc. via a communication network etc., for example. The acquired actual measurement value is used in each element of the operation support system 100 such as the deviation calculation unit 110.

The information acquired by the actual value acquisition unit 153 includes, for example, the amount of water flowing through each point of the pipeline 56, the amount of discharged water at a fixed time of equipment such as a pump station, and the consumption consumed during a fixed period by equipment such as a pump. The amount of power is included. However, the actual value acquired by the actual value acquisition unit 153 is not limited to these. The actual value acquisition unit 153 may acquire other actual values required by the deviation calculation unit 110 or the like.

Subsequently, each element shown in FIG. 2 of the operation support system 100 will be described.

The divergence calculation unit 110 obtains a difference between the plan and the actual result regarding the water distribution state. That is, the difference between the plan and the actual result regarding the water distribution state represents the degree of deviation. Then, the equipment related to the location where the degree of deviation is large is extracted as the equipment that is inefficiently operated.

The plan is a value indicating the status of individual facilities when the distribution network 50 is operated based on the distribution plan obtained by the distribution plan acquisition unit 152. The plan may include the water pressure and flow rate at each point of the water distribution network 50 when facilities such as a pump station are operated based on the water distribution plan. The value used as the plan may be a value determined in the water distribution plan. In addition, the record is a value indicating the actual water distribution status in the distribution network 50 acquired by the record value acquisition unit 153. In the present embodiment, it is assumed that the plan uses an ideal value based on a water distribution plan optimized according to some criteria as described above.

Each of the plan and the results used in the divergence calculation unit 110 includes, for example, the amount of water at each point of the pipeline 56 of the water distribution network 50, the amount of water supplied for a fixed time of equipment such as a pump station, and the like. However, the plan and the actual results are not limited to these, and may include information necessary for extracting facilities that are inefficiently operated in the water distribution network 50.

The deviation calculation unit 110 obtains the difference between the plan and the actual result for each facility constituting the water distribution network. The target facility includes, for example, a pipeline 56 constituting the water distribution network 50. In this case, for example, the flow rate of water flowing through the pipeline 56 is used as the state of water distribution. That is, the divergence calculation unit 110 obtains a difference between the flow rate plan and the actual result for each pipeline 56 constituting the water distribution network, for example. The divergence calculation unit 110 may obtain differences for all the pipelines 56 included in the water distribution network 50, or obtain differences for the main pipelines 56 among the pipelines 56 included in the water distribution network 50. Also good.

In the water distribution network 50, each facility may be operated independently. When the situation of the water distribution network 50 changes from the plan due to a change in demand or the like, the operation is individually changed in each facility. By individually changing the operation in each facility, the operation of the water distribution network 50 may deviate from an ideal plan optimized with respect to an arbitrary standard as a water distribution plan. That is, in the water distribution network 50, there is a possibility that an inefficient operation different from the plan is performed.

Therefore, when the operation support system 100 derives the operation correction policy, first, the divergence calculation unit 110 obtains a divergence between the plan and the actual result. The difference between the plan and the actual result obtained by the divergence calculation unit 110 is an index for evaluating whether an efficient operation according to the plan is performed. That is, the difference between the plan and the actual result is large, that is, the pipeline 56 where the two are separated is evaluated as a facility that is inefficiently operated.

The divergence calculation unit 110 obtains a difference between the plan and the actual result regarding the state of water distribution by appropriately using a known method. As an example, the divergence calculating unit 110 obtains the sum of absolute values of differences between the flow rate plan and the actual results as the difference for each pipeline 56 in a specific period. The specific period is, for example, one day, but is not limited thereto. The specific period may be determined as appropriate according to fluctuations in the demand for water at each point of the water distribution network 50. Further, the divergence calculating unit 110 may obtain the difference by adding together the absolute values of the differences between the planned flow rate and the actual value obtained at regular intervals for each pipeline 56. The fixed interval is, for example, every 15 minutes, but is not limited thereto.

FIG. 4 shows an example of the planned value and the actual value of the flow rate in each pipeline 56. In the example shown in FIG. 4, the plan and actual results of the flow rate relating to the three pipelines 56-1 to 56-3 are shown. In the example shown in FIG. 4, the dotted line indicates the planned flow rate value, and the solid line indicates the actual flow rate value. The vertical arrow described in the graph of the pipeline 56-1 indicates the absolute value of the difference between the flow rate plan and the actual result. The divergence calculating unit 110 obtains the difference by adding together the absolute values of the differences between the flow rate plan and the actual results as indicated by the arrows, for example.

Note that the divergence calculating unit 110 may obtain the difference using other known methods such as cosine similarity and sample correlation. The deviation calculation unit 110 obtains the difference between the plan and the actual result using these methods.

The distribution range estimation unit 120 is configured to determine the relationship between each facility and demand point provided in the distribution network and the distribution point based on each of the plans and results regarding the water flow and distribution state in the distribution network. To estimate. More specifically, the water distribution range estimation unit 120 determines the range of the demand point 55 distributed by each of the pump stations 57 provided in the water distribution network 50 based on the plan and the actual result of the water flow in each of the pipelines 56. Seek for each of the achievements. The range of the facility of the demand point 55 which the pump station 57 distributes water and the other distribution network 50 is called a water distribution range. That is, the water distribution range estimation unit 120 estimates the water distribution range of the pump station 57. The water flow in each of the pipelines 56 includes, for example, the water feeding direction and the amount of water that are the directions of water flow in each of the pipelines 56.

The water distribution range estimation unit 120 estimates the water distribution range by tracing the water flow in each of the pipelines 56 from the pump station 57 to the demand point 55. An example of the procedure for estimating the water distribution range by the water distribution range estimation unit 120 will be described with reference to FIG. As shown in FIG. 5, pump stations 57-1 to 57-5 are provided in each of the water purification plant 53 and the water supply station 54, respectively. The water distribution range estimation unit 120 estimates the water distribution ranges of the pump stations 57-1 to 57-5, for example.

In addition, in each figure after FIG. 5, the numerical value enclosed with the frame attached | subjected with respect to each of the pipeline 56 shows the amount of water in each of the pipeline 56. FIG. In the following description, the amount of water represents the amount of water sent per unit time in the pipeline 56. The value of the water amount may represent an absolute amount of water, or may be a value representing a relative relationship between the amounts of water flowing through the plurality of pipes 56.

Further, in FIG. 5, the direction of each arrow in the pipeline 56 indicates the direction of water supply in each pipeline 56. These water supply directions or water amounts are values obtained by the water distribution plan acquisition unit 152 or the actual value acquisition unit 153, respectively, as either a plan or an actual result. The water distribution range estimation unit 120 estimates the water distribution range in each case based on the water flow obtained as a plan or an actual result. In the example shown in FIG. 5 and subsequent figures, an arrow shown on the pipeline 56 connecting elements of the water distribution network 50 represents the water supply direction in the pipeline 56.

When estimating the distribution range by the distribution range estimation unit 120, it is necessary to consider the water flow at the branch point of the distribution network 50. The water distribution range estimation unit 120 first estimates a water flow at a branch point. As a branching point to consider, when water flows from one pipe and is sent to multiple pipes, when water flows from multiple pipes and is sent to one pipe, The case where water flows in from the road and is sent to a plurality of pipes is included.

In the example of FIG. 5, when water flows into a plurality of pipes at a branch point A from one pipe, the water flows into a plurality of pipes at a branch point B or D and one pipe When water is supplied to the road, the branch point C corresponds to a case where water flows in from a plurality of pipes and is supplied to the plurality of pipes. The water distribution range estimation unit 120 estimates the following water flow for each branch point.

When water flows from one pipe line and is sent to a plurality of pipe lines as at the branch point A, the water distribution range estimation unit 120 determines that the water that has flowed in depends on the amount of water that has branched from the branch point A. Estimated to be distributed. At the branch point A, the water distribution range estimation unit 120 has the water amount 270 flowing into the branch point A from the pump station 57-4 via the pipeline 56 as the water amount 120 and 150, and the demand point 55-3 and the branch point. Estimate that each is distributed to C.

When the water that has flowed in from the plurality of pipes 56 is sent to another one pipe as in the branch point B, the water distribution range estimation unit 120 determines that all of the inflowed water is in the other one pipe. It is estimated that water will be sent to the road.

At the branch point B, water with a water volume of 100 flows from the pump stations 57-2 and 57-3. Therefore, the water distribution range estimation unit 120 estimates that water having a water volume of 200 is supplied from the branch point B to the branch point C. Further, the water distribution range estimation unit 120 estimates that the water supplied to the branch point C includes 100 each of the water flowing in from the pump stations 57-2 and 57-3.

When the water flowing in from the plurality of pipelines 56 is sent to the plurality of pipelines as in the branch point C, the water distribution range estimation unit 120 determines that the water flowing into the branch point C is the amount of water in the pipeline after branching. It is estimated that the water will be distributed to each pipeline according to the situation.

In the example shown in FIG. 5, water having a water amount of 150 flows from the branch point A and water having a water amount of 200 flows from the branch point B to the branch point C. The water flowing from the branch point B to the branch point C includes 100 pieces of water flowing from the pump stations 57-2 and 57-3. In the example shown in FIG. 5, the water flowing into the branch point C is sent from the branch point C to each of the demand point 55-2 and the branch point D. In this case, water with a water volume of 280 is sent from the branch point C to the demand point 55-2, and water with a water quantity of 70 is sent from the branch point C to the branch point D. That is, the water flowing into the branch point C is sent to the two pipe lines at a ratio of 4: 1.

In this case, the water distribution range estimation unit 120 estimates that the water flowing into the branch point C is distributed and sent at a ratio of 4: 1 to each pipeline. That is, the water distribution range estimation unit 120 supplies water 150 from the pump station 57-4 and flows from the branch point A to the demand point 55-2 and the branch point D, respectively. It is estimated that water is distributed and distributed in proportion.

Similarly, the water distribution range estimation unit 120 distributes the water with the amount of water 200 flowing in from the branch point B to the demand point 55-2 and the branch point D at a ratio of the water amount 160 and the water amount 40, respectively. Estimated. In addition, the water flowing in from the branch point B includes 100 amounts of water sent from the pump stations 57-2 and 57-3. Therefore, the water distribution range estimation unit 120 has the water volume 100 sent from each of the pump stations 57-2 and 57-3 to the demand point 55-2 and the branch point D, respectively. It is estimated that water is distributed and distributed in proportion.

That is, the water distribution range estimation unit 120 supplies water from the pump stations 57-2, 57-3, and 57-4 to the water supplied from the branch point C to the demand point 55-2, respectively. It is estimated that the water amount 80 and the water amount 120 are included.

Moreover, when the water which flowed in from the some pipe 56 is sent to several pipes like the branch point C, the water distribution range estimation part 120 respond | corresponds to the ratio of inflow of the water which flows into the branch point C. Therefore, it may be estimated that the water is distributed and sent to each pipeline after branching.

In the example shown in FIG. 5, 150 water flows from the branch point A and 200 water flows from the branch point B. The water flowing in from the branch point B includes 100 water each flowing in from the pump stations 57-2 and 57-3. That is, in this case, water flows from each of the pump stations 57-2, 57-3 and 57-5 to the branch point C at a ratio of 2: 2: 3.

Therefore, the water distribution range estimation unit 120 is configured such that the water flowing in from each of the pump stations 57-2, 57-3, and 57-4 is 2: 2 from the branch point C to each of the demand point 55-2 and the branch point D: It is estimated that water is distributed and distributed at a ratio of 2: 3.

In the example shown in FIG. 5, 280 water is sent from the branch point C to the demand point 55-2. The water distribution range estimator 120 is configured such that the water sent from each of the pump stations 57-2, 57-3 and 57-4 is supplied to the water 280 in accordance with the above-described inflow ratio. And it is estimated that the amount of water is 120.

Similarly, in the example shown in FIG. 5, 70 water is sent from the branch point C to the branch point D. The water distribution range estimation unit 120 is configured such that water supplied from each of the pump stations 57-2, 57-3, and 57-4 is supplied to each of the water 70 and the water 20 according to the above-described inflow ratio. And it is estimated that the amount of water is 30. These results are the same as those described above, assuming that water flowing in from a plurality of pipes 56 is distributed according to the amount of water in the pipes 56 after branching.

Further, the branch point D corresponds to the case where the water flowing in from the plurality of pipelines 56 is sent to another one pipeline, as is the case with the branch point B. Therefore, the water distribution range estimation unit 120 flows into the water 370 having the amount of water sent from the branch point D to the demand point 55-1 and the water having the amount of water 300 flowing from the pump station 57-1, and from the branch point C. It is estimated that 70 water is included.

As described above, the amount of water 70 flowing in from the branch point C includes water flowing in from each of the pump stations 57-2, 57-3, and 57-5. The water distribution range estimation unit 120 estimates that the water 70 flowing in from the branch point C includes water 20, water 20, and water 30 as described above. That is, the water sent from the branch point D to the demand point 55-1 includes water sent from the pump stations 57-1, 57-2, 57-3, and 57-4.

The water distribution range estimation part 120 estimates a water flow as mentioned above about the branch point contained in the water distribution network 50 used as object. And the water distribution range estimation part 120 calculates | requires the demand point 55 where the water which each of the pump stations 57 sent arrives based on the water flow estimated as mentioned above. And the water distribution range estimation part 120 estimates the calculated | required demand point 55 as a water distribution range. In addition, the water distribution range estimation part 120 may handle the pipeline 56 used as the path | route to the demand point 55 estimated as a water distribution range, and its branch point as a water distribution range.

In this way, the water distribution range estimation unit 120 estimates the water distribution range, which is the demand point 55 distributed by the pump station 57, with respect to each of the planned value and the actual value. In addition, the amount of water sent from each of the pump stations 57 is estimated together with the demand point 55 and other facilities that are within the water distribution range. That is, by estimating the water distribution range by the water distribution range estimation unit 120, the relationship between the equipment in the water distribution network 50 such as the pump station 57 and the demand point 55 is obtained.

In addition, the water distribution ranges of the plurality of pump stations 57 may overlap. That is, each demand point 55 may be supplied with water from a plurality of pump stations 57. Each of the pump stations 57 that distribute water to the demand point 55 to which water is supplied from the plurality of pump stations 57 may affect each other's operation in accordance with a change in demand at the demand point 55 or the like. That is, the water distribution range estimation unit 120 calculates the relevance of each of the plurality of pump stations 57.

The correction policy deriving unit 130 is based on the difference obtained by the divergence calculating unit 110 and the relationship relating to the water distribution such as the water distribution range obtained by the water distribution range estimating unit 120, and the correction policy regarding the operation of the facilities provided in the water distribution network 50. Is derived.

The correction policy derived by the correction policy deriving unit 130 includes the facilities of the water distribution network 50 whose operation should be corrected and the content of the corrected operation. The correction policy includes the pipeline 56 whose water amount should be changed, the amount of water after correction in the pipeline 56, and the like.

As a more detailed example, the correction policy includes the pump station 57 whose operation state should be corrected, the operation state after the correction in the pump station 57, the correction amount of the parameters related to the operation of the pump station 57, and the like. Further, the correction policy may include a valve (not shown) whose state should be corrected, correction of setting of the water supply direction for the valve, and the like.

The correction policy deriving unit 130 derives a correction policy so as to reduce the difference between the plan value and the actual value based on the difference between the plan and the actual result and the water distribution range. That is, the correction policy deriving unit 130 derives the target whose operation is to be corrected and the correction content of the operation for the target so that the ideal operation according to the plan is performed in the water distribution network 50.

The correction policy deriving unit 130 determines a target for deriving the correction policy based on the difference between the plan and the actual result obtained by the deviation calculation unit 110. For example, the correction policy deriving unit 130 selects the pipeline 56 in which the magnitude of the difference between the plan and the actual result is larger than a predetermined threshold value. Then, the correction policy deriving unit 130 sets the pump station 57 associated with the pipe line 56 as a target whose operation is to be corrected.

Further, the correction policy deriving unit 130 may select a predetermined number of pipelines 56 in order of the largest difference, and the pump station 57 associated with the pipelines 56 may be a target whose operation is to be corrected. The pump station 57 associated with the pipeline 56 is a pump station 57 that supplies water to the pipeline 56, for example.

In the case described above, facilities such as a plurality of pump stations 57 may be targeted for operation correction. When equipment such as a plurality of pump stations 57 is a target to be revised, the revision policy deriving unit 130 operates, for example, in order from equipment related to the pipeline 56 having a large difference between the plan and the actual result. Derive a revision policy to be revised.

When the equipment such as the pump station 57 whose operation is to be corrected is determined, the correction policy deriving unit 130 requests the operation correction content for each equipment. The correction policy deriving unit 130 obtains a correction content of the operation such that the difference between the flow rate plan and the actual result is large, in other words, the amount of water in the pipeline 56 where the plan and actual result are different from each other approaches the plan.

A further explanation will be given for an example of the details of the operation modification. The correction policy deriving unit 130 obtains the operation correction content for the target facility so that the amount of water in the pipeline 56 selected in the above-described procedure approaches the planned value. For example, the correction policy deriving unit 130 obtains the correction contents such as the operating state of the pump station 57 so as to change the water supply amount of the pump station 57 that supplies water to the pipeline 56.

In addition, in each of the demand points 55, the operation setting value mentioned above needs to be satisfied. That is, at each of the demand points 55, even when the operation of the distribution network 50 is changed, the demand amount is assumed to be the same without changing. Therefore, the correction policy deriving unit 130 obtains the operation correction contents so that the relationship of the following expression (1) is established in each of the demand points 55.

That is, when the correction policy deriving unit 130 derives a correction policy including a correction content that changes the water supply amount of one pump station 57, the water supply amount for each of the demand points 55 is the same before and after the correction. Derive such a revision policy. In equation (1), q _di represents the amount of water sent from the pump station i to the demand point d before the correction, and q ′ _di is the pump station to the demand point d after the operation correction. Let us denote the amount of water sent from i.

More specifically, when the correction policy deriving unit 130 derives a correction policy including a correction content that changes the water supply amount of one pump station 57, the water supply amount of another pump station 57 is necessary. Derive a revision policy that adjusts The pump station 57 that requires adjustment of the total water amount due to the change in the total water amount for one pump station 57 is a pump station 57 whose water distribution range overlaps with the one pump station 57.

In this case, the correction policy deriving unit 130 sets the operation of one pump station 57 and another pump station 57 whose water distribution ranges overlap as described above. Then, the correction policy deriving unit 130 obtains the operation correction contents for the other pump stations 57 whose operation should be corrected. The correction policy deriving unit 130 requests the other pump stations 57 to correct the operation so that the amount of water supplied to the demand point 55 does not change before and after the operation is corrected. By deriving the correction policy in this way, the operation correction content that satisfies the relationship of the above-described equation (1) is obtained.

Hereinafter, with reference to FIG. 6 to FIG. 8, an example of a procedure when the correction policy deriving unit 130 obtains the operation correction content will be shown. FIG. 6 shows the results of the relationship between each of the pump stations 57-1 to 57-3 and its water distribution range. The result is acquired by, for example, the result value acquisition unit 153 or the like.

According to FIG. 6, the water distribution range in the performance of the pump station 57-1 is the demand points 55-1 and 55-2. The amount of water sent from the pump station to the pipeline 56-1 is 500. Then, a water amount 350 is distributed from the pump station 57-1 to the demand point 55-1 and a water amount 150 is distributed to the demand point 55-2.

Further, in the example shown in FIG. 6, it is shown that water is distributed from the pump station 57-2 to the demand points 55-1, 55-4 and 55-5 via the pipeline 56-2. Similarly, in the example shown in FIG. 6, it is shown that water is distributed from the pump station 57-3 to the demand points 55-1, 55-2 and 55-3 via the pipeline 56-3.

FIG. 7 shows an example of an ideal plan of the relationship between each of the pump stations 57 in the water distribution network 50 similar to FIG. 6 and its water distribution range. According to FIG. 7, the water distribution range in the example of the ideal plan of the pump station 57-1 is the demand points 55-1 and 55-2 as well as the actual value. However, when the pump station is operated according to an ideal plan, the amount of water delivered from the pump station to the pipeline 56-1 is 400. In this case, it is assumed that the water 220 is supplied to the demand point 55-1 and the water 180 is supplied to the demand point 55-2 from the pump station 57-1.

Further, in the example shown in FIG. 7, as an example of an ideal plan, it is shown that water is distributed from the pump station 57-2 to the demand points 55-4 and 55-5 through the pipeline 56-2. Yes. Similarly, in FIG. 6, as an example of an ideal plan, water is distributed from the pump station 57-3 to the demand points 55-1, 55-2, 55-3 and 55-4 via the pipeline 56-3. Has been shown to be.

In this example, it is assumed that the difference between the planned and actual amount of water in the pipeline 56-1 is the largest among the pipelines 56-1 to 56-3. Therefore, the correction policy deriving unit 130 derives a correction policy such that the amount of water in the pump station 57-1 to be fed to the pipeline 56-1 is in line with an ideal plan.

That is, the correction policy deriving unit 130 obtains a correction content regarding the operation of the pump station 57-1 so that the water amount 400 is sent from the pump station 57-1. More specifically, the amendment policy deriving unit 130 relates to the operation of the pump station 57-1 so that the water with the water amount 220 is sent to the demand point 55-1 and the water with the water amount 180 is sent to the demand point 55-2. Ask for corrections.

The correction policy deriving unit 130 changes the number of pumps operating in the pump station 57-1, the number of rotations of the pump, and the like so that the above-described amount of water is sent to each of the demand points 55. Ask for. In addition, the correction policy deriving unit 130 may obtain correction contents related to operation of other equipment.

On the other hand, at each of the demand points 55, it is assumed that the demand amount does not change even when the operation of the water distribution network 50 is changed. Accordingly, the correction policy deriving unit 130 is not limited to the pump station 57-1, and the pump stations 57-2 and 57-3 so that the total amount of water sent to the demand points 55-1 and 55-2 remains unchanged. Deriving a correction policy to change the operating state of

In the example shown in FIGS. 6 and 7, the amount of water sent from the pump station 57-1 to the demand point 55-1 is reduced by 130. Further, the amount of water supplied from the pump station 57-1 to the demand point 55-2 is increased by 30. Therefore, the correction policy deriving unit 130 derives the correction policy so that, for example, the increase / decrease in the amount of water is equally allocated to each of the pump stations 57-2 and 57-3. FIG. 8 shows an example of derivation of a correction policy.

As shown in FIG. 8, when the water distribution range from each pump station 57 remains as the actual value, the water supply amount from the pump stations 57-2 and 57-3 to the demand point 55-1 is increased by 65 respectively. It is assumed that the operation will be corrected. Further, in this case, it is assumed that the operation is modified to reduce the amount of water supplied from the pump station 57-3 to the demand point 55-2 by 30.

That is, the correction policy deriving unit 130 sets the pump stations 57-2 and 57-3 as targets for further operation correction. Then, the correction policy deriving unit 130 obtains the operation correction contents for changing the amount of water to be supplied as described above for each of the pump stations 57-2 and 57-3.

In the above example, it is assumed that the increase or decrease in the amount of water is evenly allocated to each of the pump stations 57-2 and 57-3. However, the increase or decrease in the amount of water allocated to each of the plurality of pump stations 57 may be different.

For example, depending on the performance of each pump station 57, each of the plurality of pump stations 57 may be assigned a different amount of water. Further, the increase or decrease in the amount of water allocated to each of the plurality of pump stations 57 may be changed based on the magnitude of the difference between the plan and the actual results in the pipeline 56 through which each pump station 57 supplies water.

Also, when the water distribution range of the pump station 57 is different between the plan and the actual results, the correction policy deriving unit 130 may derive a correction policy for changing the water distribution range. That is, the demand point 55 included in the water distribution range of a certain pump station 57 may change before and after the operation plan is corrected.

In this case, the correction policy deriving unit 130 derives the correction policy so as to change the water supply direction of the pipeline 56 included only as a water distribution route with respect to the demand point 55 included either before or after the correction. . In other words, the correction policy deriving unit 130 derives the correction policy so as to change the water supply direction of the pipeline 56 that is not included as a water distribution route to the demand point 55 included in both before and after the correction. FIG. 9 or FIG. 10 shows an example of deriving a correction policy by the correction policy deriving unit 130 in this case.

FIG. 9 shows a derivation example of the correction policy when the actual distribution range of the pump station 57 is larger than the plan. That is, FIG. 9 is an example in the case of reducing the water distribution range by the pump station 57.

As shown in the area surrounded on the upper side of FIG. 9, in the actual results, the water distribution range of the pump station 57-2 is the demand points 55-1, 55-4 and 55-5. On the other hand, as shown by the area surrounded on the lower side of FIG. 9, in the plan, the water distribution range of the pump station 57-2 is the demand points 55-4 and 55-5. In this case, the correction policy deriving unit 130 derives the correction policy so that the water distribution range of the pump station 57-2 is two demand points 55-4 and 55-5.

In this case, the correction policy deriving unit 130 first specifies the pipeline 56 serving as a water supply route from the pump station 57-2 to the demand point 55-1. And the correction policy derivation | leading-out part 130 divides | segments the pipe line 56 used as a water supply path for every branch point.

Subsequently, the amendment policy deriving unit 130 serves as a water supply route to a demand point (hereinafter sometimes referred to as “invariable demand point”) included in both the planned and actual water distribution ranges of the divided pipelines 56. A pipeline 56 that is not included and is not a terminal pipeline is identified. That is, the correction policy deriving unit 130 identifies the pipeline 56 that is not the terminal pipeline that is the route to the demand point 55 included only in the actual results, among the pipelines 56 included in the water distribution range of the pump station 57. In addition, the pipe line 56 used as a terminal pipe line is the pipe line 56 connected with the demand point.

In the example shown in FIG. 9, the pipe 56 that is connected between the branch points D and E and is thicker than the other pipes 56 is not included in the water supply route to the constant demand point, It corresponds to a pipeline that is not a pipeline. The correction policy deriving unit 130 derives the correction policy so as to change the water supply direction of the pipeline 56.

In this case, the correction policy deriving unit 130 derives a correction policy that changes the setting of the valve or the like provided in the pipe 56 described above. That is, the correction policy deriving unit 130 sets the valve provided in the above-described pipeline 56 as a target whose operation is to be corrected. Then, the correction policy deriving unit 130 obtains the correction details of the operation related to the control of the valve so as to change the water supply direction in the pipeline 56.

In this case, the amendment policy deriving unit 130 derives the amendment policy according to the above-described procedure or the like so that the amount of water supplied to the demand points 55-4 and 55-5 is in line with the plan along with the change of the water supply direction. To do.

FIG. 10 shows a case where the actual distribution range of the pump station 57 is smaller than planned. That is, FIG. 10 is an example in the case where the water distribution range by the pump station 57 is increased.

As shown in the area surrounded on the upper side of FIG. 10, in the actual results, the water distribution range of the pump station 57-3 is the demand points 55-1, 55-2 and 55-3. On the other hand, as shown in the area surrounded on the lower side of FIG. 10, in the plan, the water distribution range of the pump station 57-3 is the demand points 55-1, 55-2, 55-3 and 55-4. It is. In this case, the correction policy deriving unit 130 derives the correction policy so as to expand the water distribution range of the pump station 57-2 to four demand points 55-1, 55-2, 55-3, and 55-4.

The correction policy deriving unit 130 identifies the pipeline 56 that is not included in the water supply route to the unchanged demand point and is not the terminal pipeline, as in the above-described example. Also in the example shown in FIG. 10, as in the example shown in FIG. 9, the branch points D and E are connected to each other, and the pipe line 56 that is shown thicker than the other pipe lines 56 becomes an unchanging demand point. It corresponds to the route not included in the water transmission route. The correction policy deriving unit 130 derives the correction policy so as to change the water supply direction of the pipeline 56. For example, the correction policy deriving unit 130 derives a correction policy that changes the setting relating to the water supply direction of the valve or the like provided in the pipe 56 described above. In addition, the correction policy deriving unit 130 determines the pipeline 56 to be connected to the demand point 55 that becomes the new distribution range from the original distribution range, thereby obtaining the pipeline 56 whose water supply direction should be changed, and A correction policy for changing the water supply direction of the path 56 may be derived.

Note that the revision policy deriving unit 130 may derive a revision policy that is a procedure different from the procedure described above. The correction policy deriving unit 130 may derive a correction policy different from the policy for changing the operation method of the pump station 57 so that the difference between the plan and the actual result becomes small. The correction policy deriving unit 130 may derive a correction policy for changing the operation method of other equipment provided in the water distribution network 50 so that the difference between the plan and the actual result is reduced.

As described above, in the distribution network 50, each facility may be operated independently. For example, when the situation of the water distribution network changes from the plan due to a change in demand or the like, the operation is individually changed in each facility. Therefore, it may be difficult to change the operation state so that the entire distribution network 50 approaches an ideal plan.

On the other hand, for example, as described above, the correction policy deriving unit 130 has a large difference between the plan and the actual result. Ask individually. Then, the obtained correction contents are individually applied to each facility. The amendment policy deriving unit 130 can be applied to actual operation of the distribution network and can derive an operation amendment policy that can improve the operation of the distribution network 50.

Subsequently, an operation example of the operation support system 100 according to the present embodiment will be described with reference to a flowchart shown in FIG.

The processing from step S101 to S103 is processing for acquiring data necessary for deriving the correction policy. Initially, the water distribution network information acquisition part 151 acquires the setting value in the water distribution network 50, and the information regarding the structure of the water distribution network 50 (step S101).

Next, the water distribution plan acquisition unit 152 acquires a water distribution plan in the water distribution network 50 (step S102).

Next, the actual value acquisition unit 153 acquires the actual value regarding the operation state of the facility in the water distribution network 50 (step S103).

The processing from step S104 to S106 is processing in which the operation support system 100 derives a correction policy using the data acquired in steps S101 to S103.

The deviation calculation unit 110 obtains a difference between the plan relating to the water distribution state and the actual result based on the water distribution plan acquired in step S102 and the actual result obtained in step S103 (step S104).

The water distribution range estimation unit 120 estimates the water distribution range of each pump station for each of the plan and the results based on the water distribution plan acquired in step S102 and the results obtained in step S103 (step S105). ). The water distribution range estimation unit 120 estimates the water distribution range for each of the planned value and the actual value.

The correction policy deriving unit 130 derives an operation correction policy on the basis of the difference between the plan and actual results regarding the distribution state obtained in step S104 and the distribution range obtained in step S105 (step S106). ).

The derived operation modification policy is transmitted to, for example, the water distribution operation system 10 and each facility of the water distribution network 50. Then, in each facility of the water distribution network 50, the water distribution network 50 is operated in accordance with the correction policy.

Further, the operation of the operation support system 100 described above may be repeated. For example, when a modification policy for some facilities in the water distribution network 50 is derived by the above-described operation, the operation of the facility is modified. There is a possibility that the difference between the plan and the actual results will change as the operation is modified. In this case, the operation support system 100 operates to derive a correction policy for other equipment. It is assumed that the actual operation of the water distribution network 50 approaches the plan by repeatedly performing the operation of the operation support system 100 and the operation of the facility.

As described above, the operation support system 100 according to the present embodiment relates to the operation of the water distribution network based on the difference between the plan and the actual result in each of the facilities of the water distribution network and the relationship regarding the water distribution between the facilities and the demand points. Derive a revision policy. The amendment policy related to the distribution network brain operation includes equipment and amendments that should be revised.

As described above, the distribution network generally has a complicated configuration. In addition, the state of the water distribution network changes according to demand and the like. And each operation of the equipment of a water distribution network may be performed separately. Therefore, even when an operation plan that optimizes the operation of the entire distribution network is required, it may be difficult to apply such a plan to actual operation.

In the present embodiment, the operation support system 100 identifies a facility whose operation is to be corrected based on, for example, a difference between an optimized ideal plan and operation. Then, the operation support system 100 derives an operation correction policy for the facility.

-By deriving the revision policy for each facility, the derived revision policy can be easily applied to actual operation even when each operation of the distribution network facility is performed individually. The correction policy is derived based on, for example, an optimized ideal plan. For this reason, it is assumed that the operation of the distribution network will approach the optimized ideal distribution plan by operating the distribution network in accordance with the derived correction policy.

In other words, the operation support system 100 enables the derivation of a correction policy regarding the operation of the equipment that makes the operation of the water distribution network more efficient.

Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
