Fig. 1 is a schematic diagram of an application scenario of a power control method of an air compressor system according to some embodiments of the present disclosure.

In the application scenario of fig. 1, first, the computing device 101 may obtain a target air consumption 102 of the air compressor system, a power of at least one fixed-frequency air compressor and a power of at least one variable-frequency air compressor in the air compressor system, and obtain a power set 103. Then, based on the above target gas usage 102 and the above power set 103, the computing device 101 may establish an objective function 104 for minimizing the power of the above air compressor system. Then, the computing device 101 may solve the objective function to obtain target powers of each fixed-frequency air compressor and each variable-frequency air compressor in the air compressor system, so as to form a target power set 105. Finally, based on the target power set 105, the computing device 101 may adjust the power of each fixed frequency air compressor and each variable frequency air compressor in the air compressor system, as indicated by reference numeral 106.

The computing device 101 may be hardware or software. When the computing device is hardware, it may be implemented as a distributed cluster composed of multiple servers or terminal devices, or may be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices enumerated above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.

It should be understood that the number of computing devices in FIG. 1 is merely illustrative. There may be any number of computing devices, as implementation needs dictate.

Fig. 2 is a flowchart of a power control method of an air compressor system according to an embodiment of the present disclosure. The power control method of the air compressor system of fig. 2 may be performed by the computing device 101 of fig. 1. As shown in fig. 2, the power control method of the air compressor system includes the following steps:

step S201, obtaining a target air consumption of an air compressor system, power of at least one fixed frequency air compressor and power of at least one variable frequency air compressor in the air compressor system, and obtaining a power set.

In some embodiments, an executing subject (e.g., the computing device 101 shown in fig. 1) of the power control method of the air compressor system may obtain the target gas consumption and the power set by a wired connection manner or a wireless connection manner. The air compressor system comprises at least one fixed-frequency air compressor and at least one variable-frequency air compressor. The target air consumption can be the target air consumption required by the air compressor system, and the target air consumption can be changed according to the system requirement. The fixed frequency can be the rated frequency adopted by power generation, transmission, transformation and distribution equipment of a power system and industrial and civil electrical equipment, and is in Hz. . As an example, the grid frequency of the current power supply is 50Hz, so the fixed frequency is 50Hz, and the frequency range of the frequency converter is less than or equal to the grid frequency.

It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.

Step S202, based on the target air consumption and the power set, establishing an objective function for minimizing the power of the air compressor system.

In some embodiments, the execution subject may establish an objective function for minimizing the power of the air compressor system based on the target air usage and the power set. Here, the constraint conditions of the objective function at least include: power constraint condition, air supply pressure constraint condition and air supply quantity constraint condition.

In some optional implementations of some embodiments, the power constraint at least includes: the power of a fixed-frequency air compressor in the air compressor system is in direct proportion to the first power of frequency, and the power of a variable-frequency air compressor in the air compressor system is in direct proportion to the third power of frequency.

As an example, if there are 6 fixed-frequency air compressors and 2 variable-frequency air compressors in the air compressor system, x is used₁And x₂Representing the state of 2 variable-frequency air compressors, and using x₃、x₄、x₅、x₆、x₇And x₈Showing the state of 6 constant frequency air compressors. The states include an operating state and a stop state, x₁,…x₈∈[0,1]0 indicates a stop state, and 1 indicates an operation state. By x₉，x₁₀Representing the frequency of 2 variable-frequency air compressors by x₁₁,…x₁₆The frequency of the other 6 constant frequency air compressors is 50 Hz. The power of the fixed frequency air compressor is represented by P, and the power of the variable frequency air compressor is in direct proportion to the third power of the frequency of the variable frequency air compressor. Therefore, the objective function established by taking the minimization of the sum of the power of the fixed-frequency air compressor and the variable-frequency air compressor in the air compressor system as the target can be expressed as follows:

wherein, said λ₁And λ₂The value of (2) depends on the factory information of the variable frequency air compressor.

In some optional implementations of some embodiments, the supply air pressure constraint at least includes: the air supply pressure of the fixed-frequency air compressor and the variable-frequency air compressor in the air compressor system is within a preset air supply pressure range. As an example, the above-mentioned preset gas supply pressure range may be set to 7bar to 8 bar.

In some optional implementations of some embodiments, the supply air amount constraint at least includes: the sum of the air supply quantities of a fixed-frequency air compressor and a variable-frequency air compressor in the air compressor system is larger than or equal to the target air consumption quantity, the air supply quantity of the fixed-frequency air compressor is in direct proportion to the primary power of frequency, and the air supply quantity of the variable-frequency air compressor is in direct proportion to the primary power of frequency.

As an example, since the air supply amounts of the constant frequency air compressor and the variable frequency air compressor are proportional to the first power of the respective frequencies, the constraint condition can be expressed as:

wherein alpha is a coefficient, and the value of alpha depends on the respective factory information of the air compressor.

Step S203, solving the objective function to obtain the target power of each fixed frequency air compressor and each variable frequency air compressor in the air compressor system so as to form a target power set.

In some embodiments, the executing entity may perform solution calculation on the objective function by using a preset algorithm to obtain the target power set.

As an example, the above objective function may be solved using the getpy optimization package in python, and the target gas consumption q may be 420m³The air compressor 1 and the air compressor 2 are frequency conversion air compressors, the air compressor 3 to 8 is a fixed frequency air compressor, and the following parameters can be referred to:

the frequency of the 1 st and 2 nd variable-frequency air compressors is 49.55Hz (keeping 2 to be decimal) with the total power of 3575KW and 4 st, 2 nd, 5 th and 6 th.

And step S204, adjusting the power of each fixed-frequency air compressor and each variable-frequency air compressor in the air compressor system based on the target power set.

In some embodiments, the execution subject may adjust the power of each fixed frequency air compressor and each variable frequency air compressor in the air compressor system based on the target power set. As an example, according to the calculation result of step S203, the air compressors No. 1, No. 2, No. 5 and No. 6 can be controlled to operate, the power of the fixed frequency air compressor is as shown in the above table, and the frequency of the variable frequency air compressor is 49.55 Hz.

In some optional implementations of some embodiments, the method further comprises: in response to the fact that the target power which is 0 exists in the target power set, obtaining the service time of each fixed-frequency air compressor in the air compressor system to obtain a service time set; selecting a target number of use time from the use time set as target use time to obtain a target use time set; selecting at least one power as a target adjusting power based on the power of the fixed-frequency air compressor corresponding to each target using time in the target using time set to obtain a target adjusting power set; and controlling the fixed-frequency air compressor corresponding to each target adjusting power in the target adjusting power set to stop running.

As an example, it may be determined, first, which air compressors need to be stopped according to the usage time, and then, based on the information in the table provided in step S203, a part of the air compressors may be selected again as the air compressor that is preferentially stopped from operating from among the air compressors determined according to the usage time.

In summary, in the first embodiment, the optimization calculation is performed on the power of the air compressor by establishing the objective function and the constraint condition for the air compressor system, and when only part of the air compressors are variable frequency air compressors, the operation optimization of the system is realized, the energy consumption is reduced, and a large amount of cost is saved for enterprises.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
