DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy saving support method and an energy saving operation method of a load device. For example, the present invention relates to an energy saving support method and an energy saving operation method of a load device suitable for use in an energy saving operation performed in a factory or the like. .

[0002]

2. Description of the Related Art At the Kyoto Conference on Global Warming Prevention held in December 1997, Japan's global warming reduction target was set at 6% of that in 1990. Taking this opportunity, the "Law Concerning the Rational Use of Energy (Energy Conservation Law)" was revised and enforced in April 1999. Conventionally, large-scale factories have been obliged to work on energy conservation (hereinafter referred to as energy-saving), but this revision has expanded the scope of the law to middle-scale factories.

On the other hand, conventionally, for example, a fan, a blower, a pump, and the like are used for load equipment in a factory or the like, and various motors are used for driving the same. In order to save power (energy saving) of various driving motors, an inverter is often introduced. When trying to perform power-saving operation by introducing an inverter, the merits of the introduction were calculated, and an inverter was purchased or leased or rented.

[0004]

However, in the conventional method, the initial investment is large when purchasing an inverter, and the lease or rental fee is high in the lease or rental method. ,
Further, even in the case where there is no energy saving effect, payment must be continued during the contract period.

[0005] Based on these examples, the conventional business scheme and the problems will be specifically described below.

(A) Purchasing scheme and problems In the case of purchasing a combination of an inverter and a new motor, or purchasing an inverter alone, initial investment is required and the investment burden on the customer is large, and power saving is achieved as compared with the past. Is an investment before it is confirmed.

(B) Lease or rental scheme and problems In a lease of an inverter and a new motor or an inverter alone, a user contracts to purchase the equipment or device within a certain period of time. Therefore, the user cannot cancel the contract even if the equipment or device becomes unnecessary, or the user has a heavy burden.

In the case of rental, a user pays a rental fee to use the device or equipment, and this fee is usually higher than a lease fee.

The above-mentioned leasing and rental scheme has a problem that a certain lease or rental fee must be contracted and paid before it is confirmed that the realization of power saving is achieved.

The present invention has been made in view of the above problems, and enables a user who wants to save energy to receive a desired energy saving service without making any initial investment. It is an object of the present invention to provide an energy-saving support method and an energy-saving operation method of a load device in which a person who provides the above can expect sufficient profit.

[0011]

Considering the degree of power saving, the merits of energy saving are distributed between the service provider and the user. The degree of energy saving is power saving,
These are the electricity rates saved.

According to the present invention, at least an inverter is introduced into a target load equipment having a motor by a burden of a support service provider and / or a cooperator for energy saving, whereby the target load equipment can be operated by the inverter in a power-saving manner. Energy saving support method.

Here, the cooperator is a person who works in cooperation with ESCO, and includes a finance company, a facility installer, or a remodeler.

An apparatus according to an embodiment of the present invention is based on a monitoring unit provided in a target load facility having an inverter and a motor for monitoring the operation status, and a motor speed control operation by the inverter of the target load facility. Means for transmitting actual operation data from the monitoring unit via the communication system, and an arithmetic device for calculating power saving depending on a difference between an estimated value of power consumption of load equipment without an inverter and the inverter actual operation data And a processing device for calculating a merit charge based on the calculation result of the calculation device, and performing a billing process by reflecting the merit charge on the content determined in advance between the contractors. . The request for notification of the merit fee is sent directly or indirectly to the user via ES.
It may be issued to the user from the CO, or may be issued via a finance company. The fee may be a notice or a bill, or both.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method according to one embodiment of the present invention is to obtain the current power consumption of a user who owns a target load equipment having a motor and desires energy saving of the equipment, and installs an inverter in the target load equipment. Inverter control operation data when the motor speed control operation was performed, and a merit charge corresponding to power saving based on the difference between the current power consumption data and the inverter control operation data was obtained. This is a method for providing an energy-saving service in which a billing process is performed by reflecting the above-mentioned merit fee in the contract contents previously agreed between the users.

According to a method of another embodiment of the present invention, a current power consumption is obtained from an operation state of a target load facility having a motor, an inverter is introduced into the target load facility, and the motor speed is controlled by the inverter. Perform the operation to obtain inverter control operation data, obtain a merit charge corresponding to power saving based on the difference between the current power consumption data and the inverter control operation data, and obtain the contract contents prearranged among the contractors. A billing process is performed reflecting the merit fee.

Still another method of the present invention is to determine the current power consumption of an existing load facility equipped with a motor, introduce an inverter and a motor replacing the existing motor into the existing load facility, and use the motor by the inverter. Determine the power consumption of the target load equipment by performing the rotation speed control operation, obtain a merit fee based on the current power consumption and the power saving of the target load equipment including the inverter, and in advance with the user of the target load equipment Make a contract with the inverter installer including the distribution of the merit fee, transmit the power saving data to the data collection system via the communication system, and reflect the merit fee specified by the contract Charge the person.

The inverter control operation data is collected from the monitoring system via communication means such as a LAN or a telephone line. The current power consumption data is operation data based on the current actual operation state or assumed state of the target load facility.

Therefore, in the present invention, the user can achieve or contribute to the energy saving quota given by the government or the like without initial investment, and the service provider can easily obtain the energy saving profit. Can be. That is, in the present invention, unlike the conventional leasing and rental methods, there is no need to guarantee the user a minimum amount of energy saving for the above-described reason. You can receive the fee.

Contractor B (an energy-saving service provider or energy-saving equipment manufacturer), which is one of the contracting parties, determines whether the combination of the inverter and the new motor or the inverter alone is used.
Introduce to the equipment of contractor A (customer, user) who wants energy saving. In this case, if the service provider and the user agree, not only the inverter and the motor but also the pump, fan, blower and the like used together can be replaced or replaced with new equipment.

The contractor A is a person who wants to receive the energy saving service, and the contractor B is a service provider providing the energy saving service.

First, the contractor B installs the operation status data collection system in the existing facility of the contractor A, and defines the characteristics before power saving by using the current operation situation data in the existing facility. This is defined as the current power consumption. This characteristic is the contract condition before power saving. If the user does not have the equipment, the contract terms of the user are assumed based on the power consumption data of similar existing equipment owned by the service provider.

The above-mentioned operation status data collection system collects operation data of the existing equipment and equipment after the equipment is modified or replaced, and uses a communication means such as a telephone line to establish a remote service built at the start of the service. Functions as a component of the monitoring system. Further, if necessary, data is transmitted to the monitoring system at necessary intervals. As a result, power consumption after the improvement of equipment and facilities is required, and furthermore, a merit fee is required.

The contractor A (user) decides whether or not to receive the energy-saving service with the energy-saving service provider in consideration of the current power consumption and the merit charge required from the power-saving after the equipment and equipment are improved. We will consider it and sign a contract when receiving it. If there is existing data of similar equipment without actually improving or replacing the equipment or equipment, the service provider shall calculate or approximate the current power consumption and merit fee, and contract this. It can be suggested to the user whether or not to assume the assumption.

The contract conditions include the costs required for installation and replacement of the inverter and motor installed in the existing equipment due to the advantages of power consumption, fees paid by the service provider to the inverter and motor leasing and rental companies, maintenance and management costs, Costs and the like required for data collection can be considered. If the user and the service provider agree on these conditions, a power-saving system introduction contract is signed. When modifying or replacing this equipment or equipment, the user does not need to make an initial investment, and furthermore, confirms or almost confirms that energy saving will be achieved before introducing the equipment, so that the user can at least achieve energy saving. Can even receive a distribution of merit fees.

More specifically, a power-saving motor drive system introduction contract is concluded, the power-saving amount is calculated by the above-described remote monitoring system, and the power-saving motor is driven at a predetermined rate. Determine the drive system usage fee and make payment. The “rent” here is not “the fee for the installed equipment” but the contractor A
Is defined as a merit fee equivalent amount received by the contractor B.

When implementing this service, the service provider transfers the motor, inverter, data collection system equipment and the like (hereinafter referred to as service equipment) which are components of the power-saving motor drive system to the service provider's own assets. It is needless to say that it is possible to choose whether to use a third party or to use a third party asset.

According to the embodiment of the present invention, the monitoring unit for monitoring the operation status provided in the target load equipment provided with the inverter and the motor, and the motor rotation speed control operation by the inverter of the target load equipment are used. Means for transmitting actual operation data from the monitoring unit via the communication system, and an arithmetic device for calculating power saving depending on a difference between an estimated value of power consumption of load equipment without an inverter and the inverter actual operation data An energy saving service providing apparatus comprising: a processing unit that calculates a merit fee based on a calculation result of the arithmetic device and reflects the merit fee in the content determined in advance between the contractors and performs a billing process. Provided.

An apparatus according to another embodiment of the present invention comprises: a monitoring unit for monitoring the operation status of a load facility to be contracted;
Means for collecting, from the monitoring unit, actual inverter operation data based on the rotation speed control operation by the inverter provided in the target load equipment, and calculating the power saving depending on the difference between the current operation data and the actual inverter operation data. An arithmetic device that performs the calculation, and calculates the result calculated by the arithmetic device
N or an operation status data collection system having an output circuit for outputting to a telephone line is provided, and a merit fee is calculated based on the output operation result, and the merit fee is determined based on the contents previously agreed between the contractors. It is characterized by having a processing device for charging the fee in reflection.

An embodiment according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic concept of an embodiment of the present invention. The figure shows that the contractor A has a target load facility to be described later, makes a predetermined contract with the contractor B (contract including the distribution of the merit fee), and the fee transfer is performed via a finance company. . The contract signed by the contractor A (user), contractor B (service provider) and the finance company is indicated by an arrow 14.

The target load facility is a facility having a fan or a blower 1 and a pump 2 used in a factory or the like as described above. These are not the main facilities for production and manufacture, but they are large in power consumption. It is also a part where energy saving measures are relatively late. In these facilities, various motors 3 and 4 are currently used as drive sources. Therefore, users often have a desire to save energy while investing in these facilities and equipment as little as possible.

The service provider measures the current power consumption of the facility of the user who wants to save energy, or corrects the power consumption in consideration of various fluctuation factors to obtain the current power consumption of the facility. This data and the calculation result are shown to the user.

Next, the service provider installs the inverter and a new motor as a set using only the equipment inverter of the user who wants to save energy. If the user wants to upgrade the equipment, a new motor, inverter, fan, blower, etc. are installed as a set. Inverters 5 and 6 are connected to these motors 3 and 4, so that the rotation speeds of the motors 3 and 4 can be controlled by the inverters 5 and 6. Using the current power consumption data of the existing motor of the contractor A collected by the monitoring unit 7, the characteristics before power saving are defined. This characteristic is the contract condition before power saving.

The power consumption of new equipment and devices by controlling the rotation speeds of the motors 3 and 4 by the inverters 5 and 6 is monitored by a monitoring unit 7 installed by the contractor B. Desired.
Based on the operation data and the current power consumption, a merit charge (power saving) is obtained.

The equipment such as the inverters 5, 6 and the monitoring unit 7 is delivered by the contractor B, but the user does not pay for the equipment required in this case. Based on the above, the distribution of the merit fee is examined between the user and the service provider. At this time, the cost of the inverter (motor, fan, blower, pump, etc., which is often leased or rented) installed in the user's equipment by the service provider is considered. That is, it is reasonable that this cost is covered by the merit fee, not by the user.

The service provider performs operation management and after-sales service on the inverters 5 and 6 in addition to equipment delivery. These are indicated by arrows 11.

The user concludes a contract with the service provider to introduce a power-saving motor drive system including a merit fee for power saving brought about by controlling the rotation speed of the inverter.

The inverter control operation data is taken into the remote monitoring system 20 of the contractor B as operation status data. This is indicated by arrow 13.

The contractor B calculates the amount of power consumption by controlling the rotation speed of the inverter in the remote monitoring system 20, calculates and determines the usage fee of the power saving motor drive system at a predetermined rate, and executes the billing process. Do. That is, energy savings are shared by the contractors A and B according to a predetermined ratio (payback rate). However, under this agreement, the amount of energy saving of the limited target equipment (fan, blower, pump) varies depending on the operation status of the production line including the equipment, and therefore cannot be covered by the guarantee. For this reason,
This contract does not only share “energy savings exceeding a certain amount”, but rather a payback rate regardless of the size of the energy savings. In the present invention, the distribution of the merit fee to the service provider is determined by the contractor A.
May be larger than
There is a possibility that the allocation of the merit fee to the company is zero.

The obtained merit fee is transferred to contractor A and contractor B
Will be notified of the benefits. This is indicated by arrow 12.
This billing process may be performed using a financial institution such as a finance company that is frequently used for payment of money as shown in the figure. In this case, as shown by arrow 14, contractor A
And a financing company have signed a brokerage agreement. The benefit notification is also sent from contractor B to the finance company. This is indicated by arrow 15.

The contractor B may sell the motor and inverter manufactured by the company to a finance company, lease it to the contractor B, and the contractor B may introduce the motor and the inverter to the contractor A.

Based on the notice of the merit, the contractor A pays the merit fee to the contractor B via the finance company. This is indicated by arrows 16 and 17. Note that the fee collection operation is not limited to a finance company, and financial institutions such as banks, post offices, and convenience stores may be used.

In the case of a contract in which the contractor A is directly contracted with the contractor B, the contract is as shown in FIG. 2, but is substantially the same as that of FIG. 1 and will not be described repeatedly.

Service equipment such as a motor, an inverter, a monitoring unit, etc., which are owned by the contractor B, or leased or rented by the contractor, are installed at the contractor A's factory without initial investment. The installation work cost, the remodeling cost of the equipment of the contractor A, and the like may be separately determined.

The contractor A operates the target load equipment under the rotation speed control suitable for the operation. FIG. 3 shows a method for collecting power consumption before power saving.

In FIG. 3, a drive motor (IM) 32 is connected to a target load facility 31 on a system 30, and an ammeter (CT) 33 and a voltmeter provided on a line connected to the motor 32.
The current and voltage are measured from (VT) 34. Further, a load such as a flow rate and a pressure from the target load equipment 31 is detected. These measured signals and detected signals are transmitted to the monitoring unit 25 (monitoring system 24) of the operation status data collection system 22.

The current operation data is calculated based on the collected and statistical data as described above, and the result is transmitted to the arithmetic unit (PC) 26.

The above-mentioned operation status data collection system 22
Collects and statistics the operation status of the target load equipment 31 as the current operation data, and collects and statistics the inverter actual operation data during the rotation speed control operation by the inverter. The current operation data is operation data based on the current actual operation state of the target load facility 31 or the current assumed state.

This operation status data collection system 22
Monitoring system 24 for collecting inverter actual operation data
(Including the monitoring unit 25), an arithmetic unit (PC) 26 for statistically calculating the same, and a communication system 27 for transmitting the integrated electric energy to the contractor B.

The calculated result is transmitted to the communication system 27, for example, a modem 35 or the LAN 36 of the contractor A.
Is transmitted to contractor B by e-mail via. This automatic transmission is sufficient once / day, but may be performed every moment. This information collection is performed using the remote monitoring system 20 of the contractor B as shown in FIG. 1 or FIG.

The current operation data is stored in the remote monitoring system 2
The data is transmitted to the data processing device 21 located in “0” and stored in the storage device 23.

FIG. 4 shows a method of collecting actual operation data (inverter actual operation data) when the inverter INV is provided in the system to perform rotation control. The same components as those in FIG. 3 are denoted by the same reference numerals, and will not be described repeatedly.

In the example shown in FIG. 4, inverters (INV) 5, 6 are provided on the system 30.
There is an ammeter 33 and a voltmeter 34 on the upstream side. An ammeter 43 and a voltmeter 44 are newly provided downstream of the inverters 5 and 6.

The ammeters 33 and 43 and the voltmeters 34 and 44
The current and voltage measured by the monitoring system are transmitted to the monitoring unit 25 of the monitoring system 24. In addition, target load equipment 3
The load such as the flow rate and pressure of No. 1 is similarly transmitted to the monitoring unit 25. In this case, the temperature and vibration of the target load equipment 31 may be detected and transmitted to the monitoring unit 25. This detected value is used for maintenance at a later date.

Then, the power consumption is integrated based on actual operation data collection, statistics or calculations. The integrated result is transmitted to the contractor B by the communication system 27. This automatic transmission is sufficient once / day, but may be performed every moment.

This information collection is performed using the remote monitoring system 20 of the contractor B as shown in FIG. 1 or FIG. The collected actual operation data is stored in the storage device 23 of the remote monitoring system 20.

Based on the transmitted operation data, that is, the power amount, the power saving amount and the reduced merit fee can be immediately calculated by the data processing device 21 of the contractor B. Note that the same result can be obtained by installing the storage device 23 in the operation status data collection system 22 and transmitting the result to the data processing device 21. The calculation result is notified to the contractor A. Further, the merit fee may be calculated by the operation status data collection system 22. It is desirable from the viewpoint of the system configuration that the remote monitoring system 20 is used to transfer the merit fee calculation result and the two operation data to the contractor B. As a result, operation management by the remote monitoring system 20 is performed.

FIG. 5 shows an example of power consumption characteristics when a blower is used for the target load equipment 31. In the figure, the characteristic (1) is the air volume (%) in the case of the current suction damper control.
The relationship between the power consumption (%) and the power consumption is shown below. This characteristic (1)
Is defined as the collected current operation status data and is adopted as a contract condition.

The characteristic (2) shows the air volume (%) when the rotation speed control by the inverter is adopted instead of the suction damper control.
The relationship between the power consumption (%) and the power consumption is shown below. This characteristic (2)
Is the actual operation data at the time of the rotation speed control operation by the inverter. The power saving amount is calculated by subtracting the characteristic (2) from the characteristic (1).

In the above example, the blower has been described.
The power consumption can be calculated for other fans, pumps, and the like in the same manner.

As described above, the operation status data collection system 22 measures parameters (eg, air volume, flow rate, etc.) indicating the equipment operation status and the power consumption at that time. A contract condition curve before power saving shown in FIG. 6 is created from the measurement result and is set as a contract condition. FIG. 6 shows the air volume (%) and the electric power KW.
This is an example of a contract condition before power saving.

FIG. 7 shows a calculation example of the power saving effect.
The remote monitoring system 20 measures parameters (e.g., air volume, flow rate, etc.) indicating the equipment operation status and the power consumption at that time. The power saving effect is calculated as shown in FIG. 7 using the measurement result and the contract condition curve before power saving at the time of contract. The figure shows the accumulated power amount KWh for each time. In the figure, the integrated power amount before the power saving, calculated from the curve at the time of the contract, is statistically calculated, and then the integrated power amount during the power saving operation is statistically calculated every moment. Calculate the power saving effect for minutes.

The power saving effect, that is, the merit charge is obtained by multiplying the amount of power per unit from the amount of power consumption, and the merit charge is added to the contract contents agreed between the contractors A and B and, in some cases, the finance company. Perform the billing process by reflecting. From the viewpoint of the contractor A, this is a process for charging a fee.

The contractor B is paid as a return merit, for example, a half of the power saving merit of the newly introduced equipment operation. That is, the merit fee is paid after the energy saving effect is realized. The merit of power saving is that the contractor B calculates from the actual operation data and notifies the contractor A every month according to the contents determined in advance between the contractors. For the operation data, the contractor B
May be confirmed by the contractor B before the billing process is performed.

In this manner, the billing process based on the merit fee is performed. The maintenance may be performed by the contractor B free of charge, and the daily inspection may be performed by the contractor A.

FIG. 8 shows a flowchart for billing processing. As shown in the figure, the flow for the billing process is investigated in advance by marketing (S1), the application data of the contractor A is obtained, and the contractor A proposes a service provision to the contractor B ( S2).
Profitability is examined by the contractor A's on-site inspection of the equipment (S3). The current operation status data is collected, and the operation status data is collected (S4). This data collection is performed, for example, for two months, whereby data analysis, final profitability examination, and contract condition presentation are performed (S5). Then, a contract for use of the equipment is concluded (S6), and hardware such as a motor / inverter is installed (S7) to install the hardware (S8). The installed hardware is operated, and other operation status data is collected by actual operation data collection (S9). Calculation of the merit, notification of the merit, and billing processing are performed based on the obtained operation status data (S1).
