[Brief explanation of the drawings]

[0022] [Figure 1] 1 is a block diagram showing a configuration of an energy saving performance reward calculation system according to the present invention; [Figure 2] 1 is a flowchart showing the flow of a power saving performance reward calculation method according to the present invention. [Figure 3] 1 is a cross-sectional view showing the configuration of an electric dust collector which is a preferred example of an application of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings as appropriate.

[0024] <Industrial electrical equipment (electrostatic precipitators)> FIG. 3 is a diagram showing a schematic configuration of an electric dust collector 2, which is an example of industrial electrical equipment to which the "power saving performance reward calculation system for industrial electrical equipment (hereinafter also simply referred to as the "power saving performance reward calculation system")" or the "power saving performance reward calculation method for industrial electrical equipment (hereinafter also simply referred to as the "power saving performance reward calculation method")" of the present invention is preferably applied.

[0025] 3, the electrostatic precipitator 2 includes a collecting electrode 22, a discharge electrode 23, and a power supply 21, and is used to collect harmful dust and mist contained as fine particles in various types of exhaust gas. In the electrostatic precipitator 2, a DC voltage is applied from the power supply 21 to the discharge electrode 23, which generates a negative corona discharge, causing the fine particles contained in the exhaust gas to be treated to adhere to the collecting electrode 22, thereby collecting the fine particles such as mist and dust in the exhaust gas to be treated.

[0026] Here, in the electrostatic precipitator 2, a DC voltage is applied to the discharge electrode 23. Pressure The higher the voltage, the higher the dust collection efficiency. However, it is not economically preferable to continue consuming a large amount of electricity regardless of the concentration of particulates contained in the exhaust gas to be treated. To address this problem, the electric dust precipitator 2 controls the DC voltage value according to the concentration of particulates in the exhaust gas to be treated, or ,markBy controlling the ON-OFF time of the applied voltage, it is possible to save power while maintaining high dust collection efficiency. It is more preferable to control the charging voltage by a control method in which, when the concentration of fine particles in the exhaust gas to be treated that is input into the electrostatic precipitator 2 falls below a certain concentration, the charging voltage applied to the electrostatic precipitator 2 is reduced or the ON-OFF time interval of intermittent charging is extended.

[0027] In this specification, the term "power-saving power supply control device" refers, as an example, to a power supply control device (see Patent Document 1) that performs the function of reducing power consumption by appropriately controlling the value of the charging voltage from the power supply device 21 in real time in accordance with the concentration of fine particles (dust, dust, etc.) contained in the exhaust gas to be treated in the electrostatic precipitator 2 through the above-mentioned operation.

[0028] Furthermore, various power supply control devices that similarly exhibit power saving functions in various "industrial electrical equipment" other than the above-mentioned electrostatic precipitator also fall under the category of "power saving type power supply control device" in the present invention. The "power saving type power supply control device" may be configured as hardware, software, or a combination thereof.

[0029] By applying the "power saving performance reward calculation system" or "power saving performance reward calculation method" of the present invention to various industrial electrical equipment such as an electric dust collector 2 that is equipped with an "energy saving type power supply control device 21A," it becomes possible to automatically obtain the results of energy saving achieved by introducing new equipment that uses power saving technology ("power saving type power supply control device 21A") as objective numerical data ("power saving performance reward amount").

[0030] In this specification, the "power saving performance reward amount" refers to a predetermined percentage of the profits generated by the reduction in power consumption due to the introduction of the "power saving type power supply control device 21A," and is the reward amount distributed to the supplier of the industrial electrical equipment (e.g., the electrostatic precipitator 2) as a performance reward for power saving. The predetermined percentage may be determined in advance at any rate based on an agreement or contract between the equipment supplier and the equipment consumer (user). As an example of the contractual aspect, the "power saving performance reward amount" may be appropriately set when the "power saving type power supply control device 21A" is introduced, and at the same time, a contract may be made in which the equipment supplier bears the introduction cost of the equipment, thereby further promoting the spread of the "power saving performance reward calculation system" of the present invention from an economic perspective.

[0031] <Power saving performance reward calculation system> 1 is a block diagram showing the configuration of an energy-saving performance-based reward calculation system 1, which is an example of the "energy-saving performance-based reward calculation system" of the present invention. In the following explanation, the specific configuration of the "energy-saving performance-based reward calculation system" in the case where the industrial electrical equipment in which the "energy-saving performance-based reward calculation system" is installed is an electrostatic precipitator will be described in detail as an example of a preferred embodiment of the "energy-saving performance-based reward calculation system" of the present invention.

[0032] [Overall configuration] 1, the power saving performance reward calculation system 1 includes an electric power usage measuring device 11 and a calculation processing unit 12. The calculation processing unit 12 includes a reference electric power usage storage means 121 and an electric power saving performance reward calculation means 122.

[0033] [Power usage measuring device] The power consumption measuring device 11 can be configured with various types of power measuring equipment capable of measuring the amount of power consumption per unit time of the electrostatic precipitator 2 (baseline power consumption and "power consumption after power saving measures"). Furthermore, the power consumption measuring device 11 is preferably an equipment that can also acquire data related to the "operating time" of the electrostatic precipitator 2 with the "power saving type power supply control device" activated. Furthermore, it is preferable that the equipment has the function of outputting each of these measured data related to the amount of power consumption as digital numerical data to the arithmetic processing unit 12. If the equipment can meet these requirements, existing power consumption measuring equipment already installed in the electrostatic precipitator can also be suitably used as a device that constitutes the power saving performance reward calculation system 1.

[0034] Here, "standard power usage" in this specification is, in principle, the amount of power usage per unit time when the "power-saving power supply control device 21A" in the electrostatic precipitator 2 is not operated, and is the standard amount of power that serves as the basis for calculating the "power-saving performance reward amount" that can be arbitrarily set in advance by contract, etc. Furthermore, "power usage after power-saving measures" in this specification refers to the amount of power usage per unit time after the power-saving measures of the electrostatic precipitator 2 have been taken, i.e., when the "power-saving power supply control device 21A" is operated.

[0035] [Calculation processing unit] The calculation processing unit 12 performs calculation processing using the ``power consumption after power saving measures'' in the electric dust collector 2 output from the power consumption measuring device 11 and the ``standard power consumption'' per unit time pre-stored in the standard power consumption storage means 121 as input values, and calculates the ``power saving achievement reward amount'' as an output value.

[0036] The calculation processing unit 12 is connected to the power usage measuring device 11 so as to receive numerical data related to the amount of power usage from the power usage measuring device 11. This connection can be a wired connection using a dedicated communication cable, a connection via a wired LAN, or a connection using various types of wireless communication such as wireless LAN, short-range wireless communication, or a mobile phone line. Note that the calculation processing unit 12 does not need to be located near the power usage measuring device 11, but can be located in the work area of ​​the industrial electrical equipment supplier, or in another remote location as necessary, away from the power usage measuring device 11, by connecting the two so that they can communicate with each other via a wired or wireless telecommunications line.

[0037] The arithmetic processing unit 12 can be configured using, for example, a personal computer, a tablet terminal, a smartphone, etc. Alternatively, the arithmetic processing unit 12 can be configured as a dedicated device specialized for the operations related to the implementation of the present invention. Furthermore, the arithmetic processing unit 12 can be configured as an information processing device having the above functions configured as a server on the cloud, which can be shared by a large number of clients, thereby enabling the measurement of the above-mentioned power saving effects and calculation of performance-based rewards in a large number of industrial electrical facilities to be efficiently performed in a single management facility.

[0038] In any of the above configurations, the arithmetic processing unit 12 includes hardware such as a CPU, a memory, a communication unit, etc. Then, by executing the "program for calculating an energy saving performance reward" which is a computer program according to the present invention in the arithmetic processing unit 12 configured as described above, it is possible to specifically execute the various operations described below and the method for calculating an energy saving performance reward for industrial electrical equipment.

[0039] (Reference power consumption storage means) The standard power consumption storage means 121 is a storage device that stores in advance the "standard power consumption" which is the amount of power consumption per unit time in the electrostatic precipitator 2 when the "power-saving power supply control device 21A" is not operated.

[0040] (Power saving performance reward calculation method) The power saving achievement reward calculation means 122 takes as input the "standard power usage" of the industrial electrical equipment (electric dust collector 2) stored in the standard power usage storage means 121 and the "power usage after power saving measures" of the industrial electrical equipment (electric dust collector 2) measured by the power usage measuring device 11, and calculates the "power saving achievement reward amount" by performing an arithmetic operation to multiply the difference between these two power usage amounts by a "predetermined coefficient" which will be explained in detail below.

[0041] Specifically, as an example, the calculation process for calculating the "power saving performance reward amount" can be performed using the "unit price of electricity used (¥ / kWh)," the "operating time (h)" when the "power saving type power supply control device" is activated, and the "profit distribution rate (%)" stipulated in advance by a contract or the like between the supplier of the device and the consumer (user) of the device as "predetermined coefficients," as shown in Table 1 below. By performing a calculation process in which each of these values ​​is used as a "predetermined coefficient" and multiplied by the "difference between the base power use and the power use per unit time after the power saving measure is implemented," a fair "power saving performance reward amount" can be calculated as objective numerical data, as shown in Table 1, based on the actual amount of savings in electricity charges that takes into account the unit price of electricity at the time of implementation and the operating time achieved by enjoying the power saving effect. Furthermore, the "predetermined coefficient" for implementing this invention and the calculation formula for calculating the "power saving achievement reward amount" including the coefficient may be any numerical value or formula that can quantitatively calculate the "power saving achievement reward amount" within any given period of time by using the difference between the "standard power usage" and the "power usage after power saving measures" as an input value, and is not limited to the specific coefficients exemplified above or their specific combinations.

[0042] [Table 1]

[0043] <Power saving performance reward calculation method> The "power saving performance reward calculation method" of the present invention is preferably a process that can be executed by using the "power saving performance reward calculation system for industrial electrical equipment" of the present invention described above. As shown in Figure 2, this "power saving performance reward calculation method" is executed as an overall process including a reference power usage measurement step ST1 that can be executed in the power usage measurement device 11, a reference power usage storage step ST2 that can be executed in the reference power usage storage means 121, a power usage measurement step ST3 that can be executed in the power usage measurement device 11, and a power saving performance reward calculation step ST4 that can be executed in the power saving performance reward calculation means 122, by sequentially executing these steps.

[0044] However, among the above steps, the reference power usage measurement step ST1 is not an essential component of the "power saving performance reward calculation method" of the present invention. The "power saving performance reward calculation method" of the present invention can also be implemented in such a way that the "reference power usage" of the industrial electrical equipment when the power saving type power supply control device 21A is not operated is stored in the reference power usage storage means 121 in advance, and the stored numerical data is used appropriately for calculation processing as needed. In this case, the "power saving performance reward calculation method" of the present invention can also be implemented as a simpler process that omits the reference power usage measurement step ST1. Below, we will explain in detail an embodiment of the "power saving performance reward calculation method" of the present invention in which all steps ST1 to ST4 above are performed.

[0045] (Reference power consumption measurement step) The standard power consumption measurement step ST1 is a process in which the power consumption measuring device 11 measures the "standard power consumption" per unit time when the "power-saving power supply control device 21A" is not operated in the electric dust collector 2, or before the "power-saving power supply control device 21A" is introduced.

[0046] (Reference power consumption storage step) The reference power consumption storage step ST2 is a process of storing the "reference power consumption" obtained in the reference power consumption measurement step ST1 in the reference power consumption storage means 121. The stored "reference power consumption" is output from the reference power consumption storage means 121 as numerical data to be used for calculation processing as needed, and input to the calculation processing unit 12.

[0047] (Power consumption measurement step) The power consumption measurement step ST3 is a process in which the power consumption measuring device 11 measures the "power consumption after power saving measures", i.e., the amount of power consumption per unit time of the electric dust collector 2 when the "power saving type power supply control device 21A" is operated.

[0048] (Power saving reward calculation step) The power saving performance reward calculation step ST4 is a process in which the power saving performance reward calculation means 122 performs an arithmetic operation to multiply the difference between the "reference power usage" stored in the reference power usage storage means 121 and the "power usage after power saving measures" measured by the power usage measuring device 11 by a "predetermined coefficient" (for example, the "power usage unit price (yen / kWh)," "operating time (h)," and "profit distribution rate (%)" given as specific examples above) to calculate the power saving performance reward amount.

[0049] After the power saving performance reward calculation step ST4 is executed, the calculation processing unit 12 determines whether or not to terminate the execution of the power saving performance reward calculation method. For example, it is determined to be terminated when a command to terminate processing is input. If it is to be terminated, the execution of the power saving performance reward calculation method is terminated; otherwise, the process returns to the power usage measurement step ST3, and the execution of the power saving performance reward calculation method is continued.
