At this,
S: rotating speed [rpm].
As the maintenance method of the flow-lift characteristic of each rotating speed, can use approximate through above-mentioned similar law.Perhaps, also can keep the flow-lift characteristic of a plurality of representative rotating speeds, carry out interpolation and flow-lift characteristic is similar to for other rotating speeds.
With reference to Fig. 6 in the device characteristics storage part 121 stored equipment characteristic informations, the flow-efficiency characteristic of a definite pump describes.
Same with flow-lift characteristic, as reference before was shown in Figure 4, device characteristics list 300 held same flow-efficiency characteristic 304 for each pump number organizational security of control object facility.Towards water-supply line and in the turbulence pump of more use, known mass flow-efficiency characteristic is based on certain approximate in following formula 6 or the formula 7.
η=AQ^2+BQ ... (formula 6)
η=AQ^3+B Q^2+CQ ... (formula 7)
At this,
η: the efficient [-] of pump
Q: the delivery flow of pump [m^3/h]
A, B, C: to each formula coefficient independently.
Under situation about flow-lift characteristic being similar to, keep kind and coefficient A, B, the C of approximate expression to get final product through above-mentioned formula.Perhaps, also can with a plurality of representative flows and efficient to remaining data, through these data are similar to flow-efficiency characteristic with the broken line that straight line connects.
At this, the efficient of pump is meant, with pump to the water institute work of the discharging value after divided by the electric power that provides for pump drives.That is, general, be meant pump mechanical efficiency that the rating of machine of pump is put down in writing, with the efficient of motor if the value that rotating speed control is then multiplied each other with the efficient of control appliance such as frequency converter.As the maintenance method of efficiency characteristic, also can keep pump mechanical efficiency, motor efficiency, frequency converter efficient respectively.
Under the situation of the pump that carries out rotating speed control, as the curve of the solid line of Fig. 6 and dotted line, flow-efficiency characteristic becomes different curves through change in rotational speed.Same with flow-lift characteristic, the effect of rotating speed control can be similar to through the similar law of pump.Perhaps, also can the flow-efficiency characteristic under the representative rotating speed be kept, other rotating speeds are carried out interpolation and flow-efficiency characteristic is similar to.
According to device characteristics storage part 121 stored device characteristics, the electric power (cost) in the time of can confirming its operating condition to a pump evaluation.Because pump shows through amassing of delivery flow and lift discharging the merit done, so pump drives needed electric power and can be showed by formula 8.
E=kQH/ η ... (formula 8)
At this,
E: pump drives needed electric power [kW]
Q: the delivery flow of pump [m^3/h]
H: the total head of pump [m]
η: the efficient [-] of pump
K: factor of proportionality [kWh/m^4].
But so-called definite operating condition is meant and uses the characteristic of Fig. 5, Fig. 6 to confirm the Q (delivery flow) of above-mentioned formula, H (total head), η (efficient).Send the characteristic of the pipeline water distributing area etc. of water corresponding to the operating condition of other pumps in the same facility and from facility, operating condition changes.Under the situation of variable speed pump, the selection of rotating speed also influences operating condition.
With reference to Fig. 7 control law storage part 122 stored control law tables are described.In Fig. 7, what control law table 310 comprised that facility 311, operating number switch flowmeter 312, pump number machine sequence of operation 313, flow/pressure control has or not 314 and the mode 315 of flow/pressure control.
Control law table 310 is for each control object facility; To the mode of the control of the having or not of the control of sequence of operation deciding means, delivery flow and the discharge pressure of the switching flowmeter of pump operating number control, pump number machine, delivery flow and discharge pressure separately, maintain information.The sequence of operation deciding means of pump number machine is meant that the pump number machine of confirming to exist in the facility many is with what kind of sequential firing or the control law that stops.Generally, so that the equilibrium duration of runs of pump turns to purpose sets.In addition, in facility, exist under the situation of variable-ratio pump number machine, utilize variable-ratio pump number facility that the effect that reduces consumes electric power is arranged, therefore generally preferentially utilize than solid constant speed pump.The information of the switching flowmeter of pump operating number control, the sequence of operation deciding means of pump number machine can also be by to replacing with other information of confirming with reference to the transition condition of the relevant state transition of the operating number of the pump facility of stating behind Figure 11.
Under the situation of the facility that does not carry out delivery flow and discharge pressure control except the running control of pump platform number, confirm operating condition through confirming the pump number machine that turns round.But, in the situation that has variable-ratio pump number machine, carry out under the situation of valve control, in the representative manner of delivery flow and discharge pressure control, have the mode of setting discharge pressure and these 2 kinds of modes of mode of setting delivery flow.For example, in the distribution pump facility that possesses variable-ratio pump number machine,, allow delivery flow to change according to the requirement of water distributing area with the control that target is carried out revolution speed that is set at of discharge pressure.At this, be under the situation of above-mentioned distribution pump facility for example at control object facility 151, the for example storage in remote facility control device 161 of the setting means of this discharge pressure.The content of the setting means of this discharge pressure also can be kept by control law storage part 122.State after in detail will be in the explanation of Fig. 8 A.On the other hand, in the conveying pump facility,, allow discharge pressure in can carrying out the smooth and easy scope of sending water, to change arbitrarily with the control that target is carried out revolution speed, valve opening that is set at of delivery flow.But, in the facility that carries out rotating speed control,, do not carry out based on the delivery flow of the aperture adjustment of blow off valve, the adjustment of discharge pressure generally in order to reduce the energy loss of valve (blow off valve).At this; Under the situation of control object facility 151 for the above-mentioned conveying pump facility that possesses variable-ratio pump number machine; For to delivery flow as the rotating speed of target setting control infer, need be from the model (flow-pressure characteristic) of the pipeline that send the water destination of control object facility 151.This flow pipe road model is also kept by control law storage part 122.State after in detail in the explanation of Fig. 8 B.
With reference to Fig. 8 A the discharge pressure setting means in the control law storage part 122 stored control law information is described.
As before described in the control law table of Fig. 7, the facility (distribution pump facility etc.) about the control carrying out setting based on discharge pressure keeps same discharge pressure setting means.Fig. 8 A representes one of representative discharge pressure setting means, promptly is called the mode of inferring the certain control of terminal pressure.
P=P0+CQ^1.85 ... (formula 9)
This mode is to confirm discharge pressure according to delivery flow (perhaps delivery flow being applied the value that certain equalization is handled) through type 9.
At this,
P: discharge pressure [kPa]
Q: delivery flow [m^3/h]
P0, C: coefficient.
As this mode, can utilize the any-mode that only determines discharge pressure according to delivery flow.Can also use the discharge pressure that certain discharge pressure is set necessarily to control to delivery flow arbitrarily.On the other hand,, also can handle in the mode of decision discharge pressure in the delivery flow that exists with ... facility etc. through the method that in the explanation of Figure 11, specifies.
With reference to Fig. 8 B the pipeline model in the control law storage part 122 stored control law information is described.
As before described in the control law table of Fig. 7, in comprising the control object facility of variable-ratio pump number machine, the facility (conveying pump facility etc.) for the rotating speed control of carrying out setting based on delivery flow keeps same pipeline model.Pipeline model is represented for the destination pipeline that send water from this facility, the relation of needed discharge pressure P [kPa] when flowing delivery flow Q [m^3/h].As representative
P=P0+CQ^1.85 ... (formula 10)
The property model, use the formula 10 of having supposed Hai Cheng-William's formula as the pressure loss of pipeline.
At this,
P: discharge pressure [kPa]
Q: delivery flow [m^3/h]
P0, C: coefficient.
In the pipeline model of the pressure setting means of Fig. 8 A, Fig. 8 B, enumerated the identic formula example of formula, but the implication of setting is different.The controlling parameter that the information of pressure setting means is definite for having arbitrariness, relative therewith, the information of pipeline model is the model of working control object.
With reference to Fig. 9 the operating number switching flowmeter of confirming in the control law storage part 122 stored control law information, to the flow of switchable pump operating number is described.In Fig. 9, operating number switches flowmeter 320 and comprises that stopping back pump operating number 321, starting back pump operating number 322, pump stops flow 323 and pump start-up flow 324.
Operating number switches flowmeter 320, when delivery flow increases, the information that becomes the flow that makes the benchmark that the pump operating number increases is kept, and when delivery flow reduces, the information of the flow that becomes the benchmark that makes the minimizing of pump operating number is kept.If under the flow that the platform number the is increased situation identical, under the situation that this flow front and rear row output changes by a small margin, might take place frequently that priming of pump stops and deterioration that accelerating pump and electric fixtures etc. with the flow that makes the minimizing of platform number.Therefore, so that change the control that makes platform number flow that increases and the flow that the platform number is reduced.Thus, even be identical delivery flow, the also different phenomenon of operating number of pump, be called as spontaneous polarization.In the example of Fig. 9, put down in writing the pump number machine of not specifying, but in the situation of facility etc. down, also can become the table of specifying concrete pump number machine with the different a plurality of pumps of characteristic.
With reference to Figure 10 cost model storage part 123 stored cost model tables are described.In Figure 10, cost model table 330 comprises facility 331, kind 332 and cost model 333.
Cost model table 330 has been deposited at least one kind 332, cost model information 333 for each facility 331 of control object.At this, kind 332 is the precision of expression cost model or the project of approximate degree.About the detailed content of kind 332 and cost model 333, will after Figure 11 is in the explanation of Figure 14, state.
With reference to Figure 11 the cost model of certain facility of constituting in the cost model storage part 123 stored cost model information, by the solid constant speed pump of 2 variable speed pumps and 1 is described.This facility does, is the distribution pump field B among Fig. 4 and Fig. 7 in control object-based device shown in Figure 2, at this this facility is made as control object facility 151.This facility 151 has 3 pumps of total of 2 variable speed pumps (No. 1 machine, No. 2 machines) and 1 solid constant speed pump (No. 3 machines).
The control that remote facility control device 161 is carried out describes.Stride under the situation that flow threshold that the switching flowmeter of Fig. 9 put down in writing carried out changing in delivery flow, the pump operating number is changed.When 1 pump running, surpass under the situation of 11m^3/min in delivery flow, make the 2nd pump starting.
No. 1 machine or No. 2 machines as variable speed pump are preferentially turned round, No. 3 only runnings under 2 situation about having turned round of machine with appending.But, must make the pump running more than 1.In No. 1 machine and No. 2 machine runnings and make under the situation that wherein 1 stops, number machine that will accumulate the duration of runs in order to make the pump equalization duration of runs and grow stops.Set the mode of (inferring that terminal pressure is certain) to become the pressure shown in Fig. 8 A, the rotating speed of No. 1 machine and No. 2 machines is controlled.
The cost model of present embodiment comprises: with the state transition relation of the variation abstract of the pump operating condition of facility; And under its each state according to the function of the delivery flow calculation consumption electric power of facility (below be called the consumes electric power function).Figure 11 A is the state transition diagram of expression state transition relation, and Figure 11 B is the chart with the overlapping demonstration of consumes electric power function of each state.
In Figure 11 A, state AX, AY, B, C are that each pump number machine of expression facility is in the work or the information in the running.Specifically, state AX representes that No. 1 machine is in the work, No. 2 machines and No. 3 machines are the operating condition in stopping.Figure 11 A is the state transition diagram that has reproduced the control relevant with the pump platform number of remote facility control device 161.The operating number that delivery flow is striden Fig. 9 switches the threshold value that flowmeter 320 puts down in writing and under situation about changing, carries out state transition.Specifically, reduce than threshold value and pump stopped under 1 the situation in state B down-off, remote facility control device 161 corresponding to the size of accumulation duration of runs of No. 1 machine and No. 2 machines to state AX or state AY migration.
Each graphical presentation of Figure 11 B is the consumes electric power during definite delivery flow under each state.Through to each setting state consumes electric power function, even be identical flow according to the difference of state thus, consumes electric power also can be reproduced different phenomenons (spontaneous polarization).Under each state,, not necessarily need be merely the function of the delivery flow of facility according to the function of the delivery flow calculation consumption electric power of facility.The water level, the delivery flow of other facilities of suction well that also will be in the suction side of pump facility carries out interdependent function as parameter.
In the cost model of Figure 11, can comprise the pump consumes electric power non-linear property, carry out accurate cost evaluation based on the ambiguity of platform number running spontaneous polarization.Relative therewith, having used under patent documentation 1 situation with the proportional cost model of water distribution quantity (delivery flow) that put down in writing, can not reproduce non-linear property, the ambiguity shown in Figure 11 B.
When in the scope of whole delivery flow, observing, become and be downwards protruding curve, therefore under less situation of delivery flow or bigger situation, it is big that error becomes.In the delivery flow that less delivery flow or spontaneous polarization exert an influence to ambiguity, the proportional cost model can become the excessive relatively or too small evaluation of estimate of ground deviation more than 20%.
In the example of Figure 11 B, under the state AY of the state AX of only No. 1 pump running, only No. 2 pump runnings, has different consumes electric power functions.The difference of the different consumes electric power that cause of device characteristics of this No. 1 machine of performance and No. 2 machines.Even No. 1 machine and No. 2 machines for example are the pump of same model, also device characteristics produce difference owing to wear out sometimes.Through the cost model of operating condition that used consideration as Figure 11 A, even also can carry out accurate cost evaluation in this case.
In costing portion 112; Each control object facility has state machine (state transition machinery); State transition relation to cost model is simulated; And through assessing the cost (consumes electric power) with the corresponding consumes electric power function of state, carry out integration through the cost (consumes electric power) to each time, the cost (consumes electric power amount) to this facility calculates thus.
Cost model is used for according to the instantaneous value of delivery flow the instantaneous value of consumes electric power being estimated, but for application plan data 340 general employed from 10 assign to 1 hour degree average, also can directly use.Generally; The variation of the delivery flow of water-supply line facility relatively relaxes, and does not carry out bigger variation at 10 minutes in the degree, and from water source water intaking, to distribution reservoir send water etc.; Only can switch delivery flow, therefore in above-mentioned method for using, also can guarantee precision with 1 hour frequency below 1 time.In addition, in the time than 10 fens degree weak points, the influence of the transient that priming of pump stops is bigger, 10 fens above equalization flows of degree of therefore preferred use.
As stated, the evaluation object of the cost model of present embodiment also can be the electricity charge that need for the consumes electric power that obtains pump.Generally, the electricity charge are lower at the less unit price at night of power consumption.The unit price at night becomes 1/3 degree between daytime sometimes, preferably applies flexibly.Through not being with feed ration with the water-supply line application plan but putting on record, can comprise the electricity charge evaluation of the variation of unit price thus, the water-supply line application plan that can put on record and apply flexibly night electricity with 1 hour spacing below the unit.
With reference to Figure 12 in the cost model storage part 123 stored cost model information, other cost models of the facility identical with Figure 11 describe.Same with Figure 11, Figure 12 A is the state transition diagram of expression state transition relation, and Figure 12 B is the chart with the overlapping demonstration of consumes electric power function under each state.
The cost model of Figure 12 be with the cost model change approx of Figure 11 the example of cost model.In Figure 12 A, state A, B, C represent the information of the pump operating number of facility.Specifically, state A representes that the pump operating number is 1 this operating condition.
The state that the state AX of state A performance Figure 11 A and state AY have unified, the equal state of state B of state B performance and Figure 11 A, the equal state of state C of state C performance and Figure 11 A.Through the unification of state, the consumes electric power function under the state A becomes the function with the value equalization of state AX and state AY consumes electric power function separately.Through equalization, therefore the cost evaluation of the difference of the device characteristics that can not consider No. 1 pump and No. 2 pumps of becoming, but because the change of model quilt has the advantage just that becomes the accumulation duration of runs that need not consider the pump number machine etc., cost evaluation.
In application plan optimization portion 113, generate a plurality of application plan data 340 and when estimating; Since cost estimate just change; Therefore estimate the Change of Class of needed amount of calculation minimizing, optimization problem through cost, can utilize optimization gimmick more at a high speed thus.If in the device characteristics of No. 1 pump and No. 2 pumps, do not exist under the situation of effective difference, to compare with the cost model of Figure 11, the cost evaluation does not produce new error, and the cost model of Figure 12 can become the model of list more.
With reference to Figure 13 in the cost model storage part 123 stored cost model information, other cost models of the facility identical with Figure 11 describe.In Figure 13, same with Figure 11, Figure 13 A is the state transition diagram of expression state transition relation, and Figure 13 B is the chart with the overlapping demonstration of consumes electric power function under each state.
The cost model of Figure 13 be with the cost model of Figure 12 further approx change the example of cost model.In Figure 13 A, state is merely one of state A, becomes the model that does not have state transition.In addition, in Figure 13 B, the consumes electric power function is for having carried out approximate function (distinguishing linear being similar to) with a plurality of consumes electric power functions of Figure 12 B linear function (broken line) through single differentiation.In addition, in Figure 13 B, the consumes electric power function of Figure 12 B before dotted line is represented to be similar to.
Through there not being the model of state transition, can not consider ambiguity based on the cost of the difference of pump operating number.In addition, also produce nonlinear function is distinguished the linear approximate error that causes.Yet,, the advantage of the change of cost model is improved as described in the explanation of Figure 12.In the present embodiment, cost model allows certain evaluation error when considering the evaluation that is used for application plan data 340.It is former because owing to also have error from the predicted value that needs that needs prediction section 114 outputs, therefore the application plan data 340 of predictor calculation also certainly lead to error when control as required.
In the cost model of whole control object facilities; Distinguish linear when approximate when as Figure 13, offseting the power consumption force function; Can be through the optimization motor of linear plan problem or the linear plan problem of MIXED INTEGER, load and transport with program optimization portion 113 and costing portion 112 Laian County.Therefore, the high speed solution can be carried out, putting on record of best application plan needed computing time can be shortened.
With reference to Figure 14 the flow-cost of energy model of the facility that constitutes in the cost model storage part 123 stored cost model information, by 3 solid constant speed pumps is described.In this facility, do not carry out rotating speed control, valve opening control basically, and only stop to control delivery flow, discharge pressure through priming of pump.
Figure 14 A is the state transition diagram of expression state transition relation, and Figure 14 B is the chart with the overlapping demonstration of consumes electric power function under each state.Same with Figure 12 A, the state A of Figure 14 A, B, C are the information of expression pump operating number.As above-mentioned, under the situation of not carrying out rotating speed control, valve control, general delivery flow only becomes and the corresponding discrete value of pump operating condition.The consumes electric power function of Figure 14 B only also becomes obtaining the function of the value of consumes electric power with the corresponding discrete delivery flow of pump operating condition.
On the other hand, in this facility, as Figure 13, carry out state transition remove and situation based on the change of distinguishing linear approximate model under, can select the consumes electric power function that is illustrated by the broken lines of Figure 14 B.
With reference to the handling process of Figure 15 explanation for a control object facility construction cost model of cost model structure portion 111.At this, at first about from Figure 11 to facility 151 illustrated in fig. 13, the structure of cost model handled describing.
In the step 1401 of the structure that state transition concerns, cost model structure portion 111 uses control law storage parts 122 stored information, the state transition relation that making is reproduced the running halted state of each pump number machine of this facility.In the control law table 310 of Fig. 7, service firing platform number switches flowmeter 320 and pump number machine sequence of operation 313.In addition,, the condition of between each state, carrying out state transition is determined, confirm the scope of the delivery flow that each state is responsible for as described in the explanation of Figure 11 A.
Shown in figure 14, under the situation of the platform number running control of only carrying out fixed pump, use the device characteristics of pipeline model and the pump number machine in the running under each state of Fig. 8 B, obtain the delivery flow that realizes through state.Flow-the lift characteristic that is synthesized during many pump parallel runnings is obtained as follows.When lift is H1, when the delivery flow of No. 1 pump delivery flow that is made as Q11, No. 2 pumps is made as Q12, when No. 1 pump and No. 2 pumps runnings, the delivery flow when lift is H1 becomes Q11+Q12.The intersection point of flow-lift characteristic that as above-mentioned, synthesizes and the pipeline model of Fig. 8 B becomes the delivery flow that realizes through state.
In the step 1402 of the calculating of consumes electric power function, cost model structure portion 111 confirms the function (consumes electric power function) according to the delivery flow calculation consumption electric power of facility for each state that in the step 1401 of the structure of state transition relation, obtains.When certain state of selection, number machine guide look of the pump of scope of delivery flow (lower limit and higher limit) and running is determined.Can consider delivery flow is fixed on the situation in the above-mentioned scope.If have revolution speed control, valve control,, confirm to realize the controlling parameter of fixing delivery flow then according to the discharge pressure shown in the control law table 310 of Fig. 7 and the control mode 315 of delivery flow.As described in the explanation of Fig. 6, calculate the consumes electric power with corresponding each the pump number machine of this controlling parameter according to equipment characteristic information, the summation of the consumes electric power of each pump number machine is confirmed as the consumes electric power of facility.
In the cost model of Figure 11, C considers to state.In the scope of being responsible for, delivery flow Q is fixed.So, set (inferring that terminal pressure is certain) according to the discharge pressure of Fig. 8 A, confirm the discharge pressure P of control target.Generally, discharge pressure P can be approximately pump lift H through unit transformation, so pump lift H confirms.More strictly speaking, owing to applied and the corresponding correction of the water level of pump suction well, therefore also can consider the influence of this correction.
According to equipment characteristic information (flow-lift characteristic), the delivery flow Q3 of fixing fast No. 3 pumps when confirming lift H.As the row of the distribution pump field B of Fig. 7 is put down in writing, in No. 1 machine of variable speed pump and No. 2 machines, be responsible for residual flow (Q-Q3) with same traffic respectively and get final product.No. 1 machine of pump and No. 2 machines according to equipment characteristic information (flow-lift characteristic), confirm that lift is that H and flow are rotating speed S1, the S2 of (Q-Q3)/2 separately.According to the lift H that so tries to achieve, flow Q1, Q2, Q3, can also obtain efficiency eta 1, η 2, the η 3 of each pump number machine, can calculate consumes electric power E1, E2, the E3 of each pump number machine through the formula described in the explanation of Fig. 6.The consumes electric power of this facility during delivery flow Q is confirmed as E1+E2+E3.
In the step 1403 of the change of model, cost model structure portion 111 to the cost model of Figure 12 and as explaining the cost model at Figure 13, carries out the change of cost model from the cost model of Figure 11 as required.Change viewpoint existence transition relationship change and consumes electric power function change.
In the cost model of Figure 11, state AX and state AY do, the scope of the delivery flow of being responsible for much at one, the consumes electric power function is also less at identical delivery flow allowance below nominal size in addition, we can say to be similar state each other.This state is realized under the situation of the pump of same model that kind at No. 2 machines of No. 1 machine of pump and pump mutually each other.Found that the difference of the scope of delivery flow, the difference of consumes electric power function are each other similar state such below certain threshold value, through these states are unified, can be with the cost model that turns to Figure 12 of model.
On the other hand, the consumes electric power function is a nonlinear function, but on distinguishing, can be similar to through linear function.Specifically, at random select several delivery flow, the broken line with the point of the delivery flow of selecting links on chart becomes one and distinguishes linear approximate.Precision is estimated as the quadratic sum of the difference of each delivery flow nearly, and obtains this quadratic sum and become minimum such approximate most.
The cost model that so obtains with change degree, be that the precision of cost model or approximate degree are deposited in cost model storage part 123.
With reference to Figure 16 application plan optimization portion 113 stored best application plan data 340 are described.In Figure 16, application plan data 340 are made up of kind 341, the moment 342 and plan flow 343.
With reference to Figure 17 facility restriction storage part 124 stored facility restriction information are described.In Figure 17, facility restriction information 350 is made up of kind 351, project 352 and content 353.
With reference to Figure 18 the handling process of device characteristics control law update portion 115 is described.In addition, be that example describes with control object facility 151 with control object-based device 171 shown in Figure 2.In the step of updating 1701 of flow-lift characteristic, 115 pairs of flow-lift characteristics shown in Figure 5 of device characteristics control law update portion upgrade.At this, flow-lift characteristic through type 11 modellings.
H=f (Q, A, B, C) ... (formula 11)
Wherein,
H: lift [m]
Q: delivery flow [m^3/h]
When definite coefficient A, B, C, flow-lift characteristic is confirmed.In addition, rotating speed control is carried out modelling through the similar law of pump.That is, use rated speed S0, the flow-lift characteristic during rotating speed S passes through
H=f (Q * S/S0, A, B, C) * S^2/S0^2 ... (formula 12)
Formula 12 modellings
As the concrete example of function f, can use formula 2, the formula 3 in the explanation of Fig. 5, enumerated.
Through actual achievement maintenance data storage part 126, during past 1 month, waited the utilization real time data during certain, extract discharge pressure P, delivery flow Q, the water level of suction well, the running stop conditions of each pump number machine, the rotating speed of each variable-ratio pump number machine.According to the water level of discharge pressure P and suction well, H infers to pump lift.In each pump number machine, confirmed in hypothesis to use real-time running stop conditions and rotating speed, the delivery flow Q1 in the time of can inferring lift H, Q2, Q3 under the situation of coefficient A, B, C.So that the summation Q1+Q2+Q3 of this supposition delivery flow, in real time involution (Q-Q1-Q2-Q3) ^2 of the difference of delivery flow Q get for the utilization real time data and value (residual error involution with) become minimum mode, confirm that coefficient A, B, the C of each pump number machine gets final product.
Make the residual error involution and become minimum coefficient decision gimmick, can use general optimization gimmicks such as the simple method of downhill race.
In the step of updating 1702 of flow-efficiency characteristic, flow-efficiency characteristic that 115 couples of Fig. 6 of device characteristics control law update portion represent is as an example upgraded.At this, flow-efficiency characteristic through type 13 modellings,
η=g (Q, A, B, C) ... (formula 13)
Wherein,
η: efficient [-]
Q: delivery flow [m^3/h]
When having confirmed coefficient A, B, C, flow-efficiency characteristic is confirmed.In addition, rotating speed control is carried out modelling through the similar law of pump.That is, use rated speed S0, the flow during rotating speed S-lift characteristic through type 14 modellings.
η=g (Q * S/S0, A, B, C) ... (formula 14)
This moment, consumes electric power can be modeled as,
E=kQH/ η ... (formula 15)
Wherein
E: consumes electric power [kW]
K: factor of proportionality [kWh/m^4]
H: lift [m]
As the concrete example of function g, can use formula 2, the formula 3 in the explanation of Fig. 5, enumerated.
Through actual achievement maintenance data storage part 126, during past 1 month, waited the utilization real time data during certain, extract discharge pressure P, delivery flow Q, the running stop conditions of each pump number machine, the rotating speed of each variable-ratio pump number machine, the consumes electric power of each pump.Water level according to discharge pressure P and suction well is inferred pump lift H.In each pump number machine, the flow-lift characteristic that use real-time running stop conditions and rotating speed, upgrades before, the delivery flow Q1 in the time of can inferring lift H, Q2, Q3 and consumes electric power E1, E2, E3 have been confirmed under the situation of coefficient A, B, C in hypothesis.So that the involution of the difference of this supposition consumes electric power E1, E2, E3 and corresponding real-time consumes electric power is got for the utilization real time data and value (residual error involution with) become minimum mode, confirm that coefficient A, B, the C of each pump number machine gets final product.
Make the residual error involution and become the decision gimmick of minimum coefficient, for example can utilize general optimization gimmicks such as the simple method of downhill race.
The update processing of the equipment characteristic information through device characteristics control law update portion 115 can be carried out and the corresponding cost evaluation of characteristic variations of following the equipment deterioration.In addition, carrying out newly the establishing of pump facility, when rebuilding, at first the pump style set the characteristic value of record and begun and estimate,, can be updated to more and the consistent equipment characteristic information of the real attitude of utilization along with utilization savings in real time.
