DETAILED DESCRIPTION

[0019] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0020] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0021] Figure 1 is a flow chart of a method for measuring power saving of a high voltage inverter according to an exemplary embodiment. Figure 1 As shown, the method comprises the following steps: In step S11, the power frequency accumulated power of each load under multiple loads is obtained before the high-voltage inverter of the primary fan of the power generation system is modified to obtain multiple power frequency accumulated power.

[0022] Exemplarily, the accumulated power frequency electricity under different loads before the high-voltage inverter modification of the primary fan of the power generation system is implemented can be obtained from the actual big data stored in the electric energy metering management system of the power generation system. Under different loads, the power saving rate and amount of electricity saved before and after the high-voltage inverter modification may be different. Therefore, the accumulated power frequency electricity of each load under multiple loads can be obtained from the electric energy metering management system to obtain multiple accumulated power frequencies.

[0023] Optionally, step S11 includes: Obtaining a first electric quantity of a first load in multiple operating time periods under power frequency operation of the high-voltage inverter before transformation; the first load is any load among the multiple loads; The power frequency accumulated power corresponding to the first load is determined according to the plurality of first power quantities.

[0024] Exemplarily, in the electric energy metering management system, there may be a first electric quantity (i.e., power consumption) of the first load in multiple operating time periods under industrial frequency operation before the high-voltage inverter is modified. Therefore, the first electric quantity corresponding to the first load in multiple operating time periods within a set time range can be obtained from the electric energy metering management system, and the multiple first electric quantities can be summed to determine the industrial frequency accumulated electric quantity corresponding to the first load; wherein, the first load can be any one of the multiple loads.

[0025] For example, when the first load is 130MW, the first power of the high-voltage inverter of the primary fan in multiple operating periods under the power frequency operation before the transformation obtained from the electric energy metering management system is as follows: The power frequency operation time period of the primary fan: 23:30 on March 4, 2016 to 6:30 on March 5, 2016; cumulative: 7h; the first power of the primary fan = 3792.00KWh; The power frequency operation period of the primary fan: 17:00 on March 6, 2016 to 0:30 on March 7, 2016, cumulative: 7.5h; the first power of the primary fan = 4802.40KWh Then the corresponding industrial frequency cumulative power consumption of the primary fan under 130MW load = 3792.00 + 4802.40 = 8594.4KWh.

[0026] In step S12, the frequency conversion cumulative power of each load variable frequency operation under the multiple loads after the high-voltage inverter is modified is obtained to obtain multiple frequency conversion cumulative power.

[0027] For example, after the high-voltage inverter modification of a primary fan in a power generation system is implemented, the accumulated power frequency electricity under different loads can be obtained from the actual big data stored in the electric energy metering management system of the power generation system. Under different loads, the power saving rate and amount of electricity saved before and after the high-voltage inverter modification may be different. Therefore, the accumulated frequency conversion electricity of each load under multiple loads can be obtained from the electric energy metering management system to obtain multiple accumulated frequency conversion electricity.

[0028] Optionally, step S12 includes: Obtaining a second electric quantity of a second load in multiple operating time periods under power frequency operation of the high-voltage inverter before transformation; the second load is any load among the multiple loads; The frequency conversion accumulated power corresponding to the second load is determined according to the plurality of second power quantities.

[0029] Exemplarily, in the electric energy metering management system, there may be a second electric quantity (i.e., power consumption) of the second load in multiple operating time periods under the variable frequency operation after the high-voltage inverter is modified. Therefore, the second electric quantity corresponding to the second load in multiple operating time periods within a set time range can be obtained from the electric energy metering management system, and the multiple second electric quantities can be summed to determine the variable frequency cumulative electric quantity corresponding to the second load; wherein, the second load can be any one of the multiple loads.

[0030] For example, when the second load is 130MW, the second electric quantity of the high-voltage inverter of the primary fan in multiple operating periods under the variable frequency operation after transformation obtained from the electric energy metering management system is as follows: The variable frequency operation time period of the primary fan: from 11:30 on March 1, 2017 to 16:00 on March 1, 2017; cumulative: 3.5h; the cumulative power consumption of the No. 1 primary fan of the No. 1 furnace = 1317.60KWh; The variable frequency operation time period of the primary fan: 12:30 on March 4, 2017 to 16:30 on March 4, 2017; cumulative: 4h; the cumulative power consumption of the No. 1 primary fan of the No. 1 furnace = 1284.00KWh; Then the corresponding frequency conversion cumulative power of the primary fan under 130MW load = 1317.60+1284.00 =2601.6KWh.

[0031] In step S13, the power saving rate and power saving amount of the high-voltage inverter after transformation are determined according to the plurality of industrial frequency accumulated power amounts and the plurality of variable frequency accumulated power amounts.

[0032] Exemplarily, when obtaining the multiple industrial frequency accumulated power and the multiple variable frequency accumulated power, the power saving rate and the amount of power saving of the high-voltage inverter after modification under any load can be determined based on the industrial frequency accumulated power and the variable frequency accumulated power corresponding to any load, thereby obtaining the power saving rate and the amount of power saving corresponding to each of the multiple loads, and determining the power saving rate of the high-voltage inverter after modification by calculating the average value of the power saving rate corresponding to each load, and determining the amount of power saving of the high-voltage inverter based on the accumulated operating time of the high-voltage inverter under the multiple loads after modification and the power saving rate.

[0033] Through the above technical scheme, the accumulated power frequency electricity of each load under multiple loads before the high-voltage inverter of the primary fan of the power generation system is transformed, and multiple accumulated power frequencies are obtained; the accumulated frequency conversion electricity of each load under the multiple loads after the high-voltage inverter is transformed is obtained, and multiple accumulated frequency conversion electricity is obtained; the power saving rate and power saving of the high-voltage inverter after the transformation are determined according to the multiple accumulated power frequencies and the multiple accumulated frequency conversion electricity. The power saving rate and power saving rate of the high-voltage inverter are calculated according to the power consumption before and after the implementation of the power-saving technology high-voltage inverter transformation, which can improve the accuracy of calculating the power saving rate and power saving and reduce the calculation error.

[0034] Figure 2 is a flow chart of a method for measuring power saving of a high voltage inverter according to an exemplary embodiment. Figure 2 As shown, step S13 includes the following steps: In step S131, the first average power corresponding to the first load is determined according to the first power frequency accumulated power corresponding to the first load and the operating time corresponding to the first power frequency accumulated power; the first power frequency accumulated power is the power frequency accumulated power corresponding to the first load among the multiple power frequency accumulated power, and the first load is any load among the multiple loads.

[0035] Exemplarily, since the operating time of the high-voltage inverter under the same load may be different before and after the transformation, the first average power corresponding to the first load can be determined according to the first power frequency accumulated power corresponding to the first load and the operating time corresponding to the first power frequency accumulated power. The first power frequency accumulated power is the power frequency accumulated power corresponding to the first load among the multiple power frequency accumulated power, and the first load is any load among the multiple loads.

[0036] For example, in the embodiment shown in step S11, the first load is 130MW, the first power frequency cumulative power corresponding to the first load is 8594.4KWh, and the operating time corresponding to the first power frequency cumulative power is 7+7.5=14.5h, then the first average power is 8594.4÷14.5=592.72KWh / h.

[0037] In step S132, the second average power corresponding to the first load is determined according to the first frequency conversion accumulated power corresponding to the first load and the operating time corresponding to the first frequency conversion accumulated power; the first frequency conversion accumulated power is the frequency conversion accumulated power corresponding to the first load among the multiple frequency conversion accumulated power.

[0038] For example, in the embodiment shown in step S12, the first load is 130MW, the first frequency conversion cumulative power corresponding to the first load is 2601.6KWh, and the operating time corresponding to the first frequency conversion cumulative power is 3.5+4=7.5h, then the second average power is 2601.6÷7.5=346.88KWh / h.

[0039] In step S133, the power saving rate and the power saving amount are determined according to the plurality of first average power amounts and the plurality of second average power amounts.

[0040] Exemplarily, the power saving rate of the high-voltage inverter under any load can be calculated based on the first average power and the second average power corresponding to the load. For example, in the above embodiment, when the load is 130MW, the first average power is 592.72KWh / h, and the second average power is 346.88KWh / h. Then, when the load is 130MW, the power saving rate of the high-voltage inverter under the 130MW load is (592.72-346.88)÷592.72=41.5%.

[0041] In summary, the power saving rate can be determined according to the following formula:

[0042] in, Indicates the power saving rate; Indicates The first average power corresponding to the load; Indicates The second average power corresponding to the load; Indicates the number of types of the multiple loads.

[0043] In addition, the power saving of the high-voltage inverter under any load can be calculated based on the first average power corresponding to the load, the second average power, and the cumulative variable frequency operation time of the high-voltage inverter under the load after the modification. For example, in the above embodiment, when the load is 130MW, the first average power is 592.72KWh / h, the second average power is 346.88KWh / h, and the cumulative operation time of the variable frequency operation of the high-voltage inverter under the load of 130MW after the modification is 7.5h. Then, when the load is 130MW, the power saving of the high-voltage inverter under the load of 130MW is (592.72-346.88)×7.5=1843.8KWh.

[0044] In summary, and taking into account the input power of other equipment used by the high-voltage inverter under different loads, the power saving can be determined by the following formula:

[0045] in, Indicates the amount of electricity saved; Indicates The first average power corresponding to the load; Indicates The second average power corresponding to the load; Indicates Input power of other equipment used by the high-voltage inverter under load; Indicates The frequency conversion operation time of the high-voltage inverter after transformation under each load; Indicates the number of types of the multiple loads.

[0046] Through the above technical scheme, the accumulated power frequency electricity of each load under multiple loads before the high-voltage inverter of the primary fan of the power generation system is transformed, and multiple accumulated power frequencies are obtained; the accumulated frequency conversion electricity of each load under the multiple loads after the high-voltage inverter is transformed is obtained, and multiple accumulated frequency conversion electricity is obtained; the power saving rate and power saving of the high-voltage inverter after the transformation are determined according to the multiple accumulated power frequencies and the multiple accumulated frequency conversion electricity. The power saving rate and power saving rate of the high-voltage inverter are calculated according to the power consumption before and after the implementation of the power-saving technology high-voltage inverter transformation, which can improve the accuracy of calculating the power saving rate and power saving and reduce the calculation error.
