Service-delivery machines such as motor, frequency converter, monitoring arrangement are the belongingss of contracting paties B, or the contract article of contracting paties B long-term lease, or the short-term lease article, and they are set at the factory of contracting paties A under the situation of not having the investment in early stage.Can formulate separately for the executive cost of installing, the scrap build expense of contracting paties A etc.

Contracting paties A uses the object load equipment through being fit to the rotating speed that frequency converter the carried out control of operation.Fig. 3 representes to collect the method for the power consumption before frequency converter imports.

In Fig. 3; Object load equipment 31 in the system 30 is connected with drive motor (IM) 32; Current transformer (CT) 33, transformer (VT) 34 are arranged on the circuit that connects motor 32, through measuring appliances such as the galvanometer that is connected with them and voltmeters electric current, voltage are measured.In addition, detect flow, pressure even load from object load equipment 31.These signals that measure, detected signal are transferred into the monitor unit 25 of the surveillance 24 of Working state data collection system 22.According to the data of such collection, statistics, measure the operational data before frequency converter imports, its result is transferred into calculation element (PC) 26.

Above-mentioned Working state data collection system 22 is collected the working condition of object load equipment 31 as the preceding operational data of frequency converter importing.And, the operational data the when frequency converter when collection is carried out rotating speed control operation by frequency converter moves.The operational data that measures is stated behind object load equipment 31, is used as the basic data of setting the treaty conditions curve.

Above-mentioned Working state data collection system 22 is by forming with the lower part: collect the frequency converter field evidence surveillance 24 (comprising monitor unit 25), possess the calculation element (PC) 26 of memory storage, with the communication system 27 of power consumption notification contracting paties B.The memory storage that calculation element 26 is had, the operational data of conservation object load equipment 31 before frequency converter imports.

The operational data that measures just with the object load device make the corresponding power consumption of momentum, the LAN36 through communication system 27, for example modulator-demodular unit (modem) 35 or contracting paties A reaches contracting paties B through e-mail.This delivers letters 1 time on the one automatically is enough to, but also can carry out all the time.Above-mentioned information collecting, like Fig. 1 or shown in Figure 2, the Long-Range Surveillance System 20 that can utilize contracting paties B to be had carries out.That is to say that above-mentioned power consumption can be received by Long-Range Surveillance System.Long-Range Surveillance System 20 plays the effect of data processing equipment, the calculation process of stating after can carrying out.

The data that receive are like this reached the data processing equipment 21 in the Long-Range Surveillance System 20, are kept in the memory storage 23.

Fig. 4 represent to frequency converter INV be arranged under the situation that is rotated control in the system, frequency converter after importing be rotated the control running by frequency converter the time operational data device, the method for collecting.The formation identical with Fig. 3 can be by additional phase numbering together, no longer repeat specification.

In example shown in Figure 4, system 30 is provided with frequency converter (INV) 5,6, and the upstream side of this frequency converter 5,6 has to be measured with current transformer 33, measuring transformer 34.The downstream of frequency converter 5,6 newly is provided with to be measured with current transformer 43, measuring transformer 44.

By the measured electric current of measuring appliances such as galvanometer and voltmeter, voltage, reached the monitor unit 25 of surveillance 24.In addition, the momentum of doing with the flow of object load equipment 31, object load equipment that the pressure even load is represented is reached monitor unit 25 too.In this case, the further temperature of detected object load equipment 31 and vibration reaches monitor unit 25.This detected value is used to keep in repair in the future.Like this, do with frequency converter imports back object load equipment that the corresponding power consumption of momentum is measured comes out, the operational data as after the frequency converter importing is stored in the memory storage of calculation element 26.

Then, make the corresponding power consumption of momentum with frequency converter imports back object load equipment, i.e. operational data reaches the memory storage 23 of data processing equipment 20 of the Long-Range Surveillance System 20 of contracting paties B through communication system 27.This delivers letters 1 time on the one automatically is enough to, but also can carry out all the time.

Above-mentioned information gathering, like Fig. 1 or shown in Figure 2, the Long-Range Surveillance System 20 that utilizes contracting paties B to be had carries out.Operational data after the frequency converter of collecting imports can be stored in the Long-Range Surveillance System 23.

Fig. 5 and Fig. 6 represent to generate according to following two kinds of power consumptions the method for treaty conditions curve.The one, the object load equipment that the object load equipment 31 before importing to frequency converter is obtained make the pairing power consumption of momentum data; Another be the object load equipment obtained of the object load equipment 31 after importing to frequency converter make the pairing power consumption of momentum data.

At first, as shown in Figure 6, concern designated with the corresponding power consumption of momentum data of doing of object load equipment.Shown in Figure 6 is, uses blower fan as the object load equipment, adopts air quantity as making the momentum data, with situation about representing with respect to specified 100% ratio.According to measured value, make the pairing power consumption kw of air quantity % (X axle) (Y axle) after frequency converter imports.The two relation, as shown in Figure 6, can be set at curve.Like this, the calculation element 26 of Working state data collection system 22, according to the working signal of frequency converter of input, the operational data all the time of the drive motor 32 after frequency converter imported is a power consumption data, carries out calculation process, generates this power consumption data.This power consumption data is set according to following relation, promptly with calculate frequency converter and import after all the time power consumption the time, the relation of making the momentum data of the object load equipment 31 that is detected and imports, for example as stated and the relation between the air quantity %.

Be expressed as shown in Figure 5 with the corresponding power consumption % of air quantity % (consumption ratio) of such setting to specified 100%.Expression power consumption % is the power consumption characteristics curve to the figure line of the relation of this air quantity %, when its expression is carried out rotating speed control with frequency converter and the corresponding power consumption % of air quantity % all the time.

Before frequency converter imports; All the time the power consumption data of the object load equipment of measuring according to the calculation element of Working state data collection system 22 26 31, the air quantity % (making the momentum data) of the object load equipment 31 before frequency converter imports is kept in the memory storage of calculation element 26 with the relation of power consumption data in advance.

Under this situation; In Fig. 5; Power consumption before frequency converter during the air quantity % of frequency converter rotating speed control power consumption characteristics curve down imports is confirmed out with reference to the air quantity % and the power consumption data that are kept in the memory storage, when distribution air quantity % to the air quantity % that is stored in the memory storage 23; When obtaining at some, set out a curve according to these points.Family curve before it imports as frequency converter, being configured to air quantity % is that X axle, power consumption kw are the coordinate of Y axle.Therefore; When determining all the time the air quantity % in frequency converter when operation; Can be according to the illustrative blower fan power consumption characteristics figure line of Fig. 5; That is, the point on the power consumption characteristics curve before frequency converter imports, with the X axle on it point on power consumption characteristics curve after the corresponding frequency converter importing poor, obtain the saving power consumption.This saving power consumption is stored in the memory storage 23.

Like this; The data processing equipment that constitutes by Long-Range Surveillance Unit 20; Receive detected all the time air quantity % (making the momentum data) and power consumption all the time when carrying out rotating speed control after frequency converter imports; The frequency converter that utilization is kept at as the treaty conditions characteristic in the memory storage 23 imports preceding air quantity % (making the momentum data) and the relation between the power consumption data; Calculate the power consumption before the corresponding frequency converter of detected all the time air quantity % (making momentum) imports when carrying out rotating speed control after importing with frequency converter; According to the frequency converter with the treaty conditions curve calculation being imported the preceding power consumption that adds up of frequency converter importing that preceding power consumption all the time adds up and obtains; Add up and the frequency converter the obtained power consumption that adds up after importing poor with the power consumption all the time after frequency converter is imported, calculate the amount of saving energy (amount of energy saving).

The example of the power consumption characteristics when like this, the load equipment 31 of Fig. 5 indicated object adopts blower fan.Among the figure, characteristic (1) is the power consumption characteristics curve of the relation of the corresponding power consumption (%) of the air quantity (%) when sucking air door control before the expression frequency converter imports.This characteristic (1) is stipulated to import preceding Working state data as frequency converter, in treaty conditions, is adopted, and becomes the treaty conditions curve.Therefore, the power consumption characteristics curve that treaty conditions curve and characteristic (1) are showed is synonym on technological layer.

The treaty conditions curve is by 4 curves of ax4+bx3+cx2+e, 3 curves of bx3+cx2+dx+e, 2 curve representations of cx2+dx+e.Perhaps, in requirement aspect client etc. in particular cases, also can represent sometimes, in this case, become the treaty conditions straight line with 1 figure line of dx+e.Therefore, adopted treaty conditions line can be treaty conditions curve or straight line.Therefore, can unify to be called the treaty conditions line.Below, the example that uses typical treaty conditions curve is described, but is also comprised the situation that changes the treaty conditions straight line into.

Characteristic (2) is illustrated in not adopt and sucks air door control, and the corresponding relation of the air quantity (%) when adopting the rotating speed control of frequency converter and power consumption (%).This characteristic (2), the power consumption characteristics curve of the operational data when carrying out rotating speed control operation by frequency converter for expression.With with measuring (%) as benchmark, deduct the numerical value on the characteristic (2) through the numerical value on characteristic (1), calculate saving power.

Though above-mentioned example is the explanation to blower fan, fan, pump machine or miscellaneous equipment for other also can calculate saving power equally.

As above,, the parameter (example: air quantity, flow etc.) and the power consumption of this moment of expression equipment work situation are measured through Working state data collection system 22.According to measuring the result, make the treaty conditions curve before frequency converter shown in Figure 6 imports, and regard it as treaty conditions.Fig. 6 representes the relation of air quantity % and power kw, and expression imports preceding treaty conditions example to the frequency converter of blower fan.
