Description

Method and device for determining station yard operation scheme and storage medium

Technical Field

The embodiment of the invention relates to the technical field of station yard energy saving, in particular to a method and a device for determining a station yard operation scheme and a storage medium.

Background

In gas pipeline projects, sites including air compressors, power generation equipment, and processing equipment may be used to process natural gas. Wherein, the air compressor machine is used for providing the air supply for all treatment facility in the station. In the design process of the station yard, in order to ensure the smooth operation of the processing equipment in the station yard, the air supply amount of the air compressor in the station yard needs to be greater than or equal to the maximum air consumption amount of the station yard, wherein the maximum air consumption amount refers to the sum of the maximum air consumption amounts of all the processing equipment in the station yard.

However, during the normal operation of the station, the air consumption of part of the processing equipment may not reach the maximum air consumption of the processing equipment, so that the air supply amount of the air compressor is far larger than the air consumption of the station. Thus, when all of the process equipment in the plant is supplied with air by the air compressor, the air compressor needs to be loaded and unloaded periodically. In order to avoid current impact on the power generation equipment caused by frequent startup, the air compressor is usually in an idle state after being unloaded, that is, the air compressor is in an idle state.

In the running process of part of stations, the idle load rate of the air compressor is high, so that extra waste of electric energy is caused, the running time of the air compressor is prolonged, and the maintenance cost of the air compressor is increased. Therefore, a method for determining a station operation scheme is needed to reduce the waste of electric energy and prolong the maintenance time of the air compressor.

Fig. 2 is a flowchart illustrating a method for determining a station yard operation scheme according to an embodiment of the present invention, where the method is applied to an electronic device, and the electronic device may be a terminal, a server, or the like. Referring to fig. 2, the method includes the following steps.

Step 201: the air consumption of each station yard in a plurality of station yards and the air supply amount of an air compressor in each station yard are obtained, and the station yards are communicated with each other.

The plurality of stations can be communicated with one another in advance through pipelines so as to ensure that any number of stations in the plurality of stations can run in a combined mode. For example, the plurality of yards includes A, B, C and D four yards, and any two of the four yards are interconnected to ensure that any two, any three, or four of the four yards can operate in conjunction.

Assuming that N stations are connected to each other, the electronic device may display a table as shown in table 1 below for the air consumption of each station and the air supply amount of the air compressors in each station to obtain the air consumption of each station and the air supply amount of the air compressors in each station.

TABLE 1

Station name	Gas consumption	Air supply amount
			First station yard
Second yard
			·····
Nth station yard

It should be noted that, for the gas consumption of each station yard, the gas consumption of each operating device in the station yard may be calculated in advance according to the actual operating conditions of the station yard, and then, the sum of the gas consumption of each operating device is determined as the gas consumption of each station yard. The air consumption of each operating device can be determined according to a metering device installed on each operating device in the normal operation process of the station yard. Or, the gas consumption of each operating device may be determined by other methods, of course, according to the physical parameters such as the actual operating pressure and the actual operating temperature of each operating device, and the density of the gas, and the like, which are not limited in the embodiment of the present invention.

After the gas consumption of each station yard is determined, the gas consumption may be manually input into table 1 by a user, and of course, a determination method of the gas consumption of each station yard may be associated with table 1, so that the determined gas consumption of each station yard may be directly entered into table 1.

The air supply amount of the air compressor in each station yard can be determined by gas simulation software based on the maximum design air supply amount of the air compressor, the operating pressure and operating temperature of the air compressor when the air compressor operates in the state of the maximum design air supply amount, and the actual operating pressure and operating temperature of the air compressor. Of course, the determination may also be performed by other methods, which is not limited in the embodiment of the present invention. Similarly, the air supply amount of each station air compressor may be manually input to the table 1 by the user after the air supply amount of each station air compressor is determined, or of course, a method of determining the air supply amount of each station air compressor may be associated with the table 1 so that the determined air supply amount of each station air compressor can be directly entered into the table 1.

Step 202: and determining a plurality of station yard combinations corresponding to the plurality of station yards, wherein each station yard combination comprises a combined operation station yard and/or an independent operation station yard, and the combined operation station yard comprises a plurality of station yards.

In the operation process of the plurality of stations, as the stations are communicated with each other, any number of stations in the stations can be operated jointly, and therefore the stations can be randomly combined to obtain various station combinations corresponding to the stations.

Wherein, the combined operation station yard included in each station yard combination can be operated jointly, and the independent operation station yard included in each station yard combination can be operated independently.

Continuing the above example, by randomly combining the four yards A, B, C and D, a first yard combination can be obtained: A. b, C and D run separately; the second station combination: A. b, C and D are operated in combination; the third station combination: A. b and C are jointly operated, and D is independently operated; and a fourth station combination: A. b and D are jointly operated, and C is independently operated; a fifth station combination: A. c and D are jointly operated, and B is independently operated; a sixth yard combination: B. c and D are operated jointly, and A is operated independently; a seventh station combination: a and B are jointly operated, and C and D are independently operated; an eighth station combination: a and C are jointly operated, and B and D are independently operated; ninth station yard combination: a and D are jointly operated, and B and C are independently operated; a tenth yard combination: b and C are operated jointly, and A and D are operated independently; an eleventh yard combination: b and D are operated jointly, and A and C are operated independently; a twelfth yard combination: c and D are operated jointly, and A and B are operated independently; a thirteenth yard combination: a and B are jointly operated, and C and D are jointly operated; a fourteenth yard combination: a and C are jointly operated, and B and D are jointly operated; a fifteenth yard combination: a and D are operated jointly, and B and C are operated jointly.

For each station yard combination in the plurality of station yard combinations obtained by random combination, at least one operation scheme of each station yard combination can be determined according to the air consumption of each station yard and/or the independent operation station yard included in the combined operation station yard and the air supply amount of the air compressor in each station yard, and then a plurality of operation schemes corresponding to the plurality of station yards are obtained, wherein each operation scheme comprises the air supply mode of the air compressor in each station yard.

It should be noted that, because the air supply amount of the air compressor in each yard is determined by design according to the maximum air consumption of all operating devices in the yard, the air supply amount of the air compressor in each yard can completely meet the air consumption of each yard, so as to realize the independent operation of each yard. Therefore, according to the following steps 203 to 205, at least one air compressor air supply set of each group of combined operation stations is determined, and at least one operation scheme of each station combination is obtained according to the air supply mode corresponding to the at least one air compressor air supply set and the air supply mode corresponding to the single operation station. Thereafter, the at least one operating plan for each yard combination is summed to obtain a plurality of operating plans for the plurality of yards.

Step 203: for each of the plurality of yard combinations, when the yard combination includes a jointly operating yard, a total gas consumption for each of at least one group of jointly operating yards included in the yard combination is determined based on the gas consumption for each yard.

For each yard combination, when the yard combination comprises a jointly operating yard, at least one group of jointly operating yards may be included in the yard combination. For each group of jointly operating yards, a total gas consumption for each group of jointly operating yards may be determined based on each yard gas consumption included in each group of jointly operating yards. The total gas consumption of each station yard included in each group of jointly operated station yards can be determined as the total gas consumption of each group of jointly operated station yards.

Continuing with the above example, for a third yard combination, comprising a set of jointly operating yards that are jointly operated with A, B and C, then the sum of the air consumption of A, the air consumption of B, and the air consumption of C may be determined as the total air consumption of the set of jointly operating yards.

Step 204: and selecting at least one air compressor air supply set corresponding to each group of combined operation station yards according to the air supply amount of the air compressor in each station yard and the total air consumption amount of each group of combined operation station yards.

Because each group of combined operation station yard can comprise a plurality of station yards, the air supply mode of each group of combined operation station yard can supply air for the air compressors in any number of station yards in the plurality of station yards. However, in order to ensure that each group of combined operation stations can normally operate, the air supply amount of each group of combined operation stations must be greater than the air consumption amount, and therefore, at least one air compressor air supply set corresponding to each group of combined operation stations can be selected as long as the total air consumption amount of each group of combined operation stations is less than the total air supply amount of the air compressors for air supply included in each corresponding air compressor air supply set. That is, at least one air compressor supply air set in which the total air compressor supply air amount is greater than the total air consumption amount of each group of combined operation stations may be determined from the plurality of air compressor supply air sets of each group of combined operation stations.

Continuing with the above example, for a group of combined operation sites included in the third site combination, the set of air compressor supplies for the group of combined sites includes: the first air compressor machine air feed collection: a is a group of combined operation station yard air supplies; the second air compressor machine air feed collection: b is a group of combined operation station yard gas supply; the third air compressor machine air feed collection: c is the gas supply of a group of combined operation stations; and a fourth air compressor air supply set: a and B are used for supplying gas for a group of combined operation stations; the fifth air compressor air supply set: a and C are used for supplying gas for a group of combined operation stations; the sixth air compressor machine air feed collection: b and C are used for supplying gas for a group of combined operation stations; seventh air compressor machine air feed collection: A. b and C supply air for a group of combined operation stations.

Removing the first air compressor air supply set because the air supply quantity of A of the first air compressor air supply set is less than the total air consumption quantity of the combined operation station; the air supply of the air supply set B of the second air compressor is less than the total air consumption of the combined operation station, and the air supply set of the second air compressor is removed; the air supply quantity of the air supply set C of the third air compressor is larger than the total air consumption quantity of the combined operation station yard, and the air supply set of the third air compressor is determined; the total air supply quantity of A and B of the air supply set of the fourth air compressor is less than the total air consumption quantity of the combined operation station, and the air supply set of the fourth air compressor is removed; the total air supply quantity of A and C of the fifth air compressor air supply set is larger than the total air consumption quantity of the group of combined operation stations, and the fifth air compressor air supply set is determined; the total gas supply quantity of B and C of the sixth air compressor gas supply set is larger than the total gas consumption quantity of the combined operation station yard, and the sixth air compressor gas supply set is determined; the total air supply quantity of A, B and C of the seventh air compressor air supply set is larger than the total air consumption quantity of the combined operation station, and the seventh air compressor air supply set is determined; therefore, four air compressor air supply sets with the total air supply quantity of the air compressors larger than the total air consumption quantity of each group of combined operation station yards can be determined from the seven air compressor air supply sets included in the group of combined operation station yards.

Step 205: and determining at least one operation scheme of the station yard combination according to the selected air supply mode corresponding to the air supply set of the at least one air compressor and the air supply mode of the air compressor in the station yard for independent operation, so as to obtain at least one operation scheme of each station yard combination.

When the station yard combination comprises a group of combined operation station yards, the air supply modes corresponding to the air supply sets of each air compressor in the air supply sets of at least one air compressor and the air supply modes of the air compressors in the independent operation station yards are combined to obtain at least one operation scheme of each station yard combination. When the station yard combination comprises a plurality of groups of combined operation station yards, randomly combining air supply modes corresponding to air supply sets of at least one air compressor of the plurality of groups of combined operation station yards included in the station yard combination to obtain at least one operation scheme of the plurality of groups of combined operation station yards, and combining the obtained at least one operation scheme of the plurality of combined operation station yards with air supplies in the independent operation station yards in respective air supply modes to obtain at least one operation scheme of each station yard combination.

Continuing with the above example, for the third yard combination, four air compressor supply air sets determined for a group of co-operating yards are included: an air supply mode corresponding to the air supply set of the third air compressor and an air supply mode of a single operation station with D as D air supply can be determined as a first operation scheme of the third station combination; determining an air supply mode corresponding to the air supply set of the fifth air compressor and an air supply mode of a single operation station with D as a second operation scheme of a third station combination; determining an air supply mode corresponding to the air supply set of the sixth air compressor and an air supply mode of the independent operation station with D as D air supply as a third operation scheme of a third station combination; and determining an air supply mode corresponding to the seventh air compressor air supply set and an air supply mode of the independent operation station with the air supply D as the D air supply as a fourth operation scheme of the third station combination, thereby obtaining four operation schemes of the third station combination.

Alternatively, for example, a thirteenth yard combination may include a first set of jointly operating yards where A and B are jointly operated, and a second set of jointly operating yards where C and D are jointly operated. Assuming that the first group of combined operation stations comprises three air compressor air supply sets, the second group of combined operation stations comprises two air compressor air supply sets, and determining an air supply mode corresponding to any one air compressor air supply set included in the first group of combined operation stations and an air supply mode corresponding to any one air compressor air supply set included in the second group of combined operation stations as an operation scheme of a thirteenth station combination, thereby obtaining six operation schemes of the thirteenth station combination.

After determining the plurality of operation schemes of the plurality of stations, in order to reduce the waste of electric energy, the idle rate of each air compressor for air supply included in each operation scheme may be determined according to steps 206 to 207, and the target operation scheme may be determined from the plurality of operation schemes based on the determined idle rate of each air compressor for air supply included in each operation scheme.

Step 206: the empty load rate of each air compressor for air supply included in each operation scheme is determined.

Specifically, the loading pressure and the unloading pressure of each air compressor for air supply included in each operation scheme are acquired, the time length for the operation pressure of each air compressor for air supply included in each operation scheme to increase from the loading pressure to the unloading pressure is determined as the loading time length, the time length for the operation pressure of each air compressor for air supply to decrease from the unloading pressure to the loading pressure is determined as the unloading time length, and the no-load rate of each air compressor for air supply included in each operation scheme is determined based on the loading time length and the unloading time length of each air compressor for air supply.

For each operation scheme, when the operation scheme includes at least one group of combined operation stations and single operation stations, the air compressors in some stations in each group of combined operation stations may be used for air supply, the air compressors in some stations may not be used for air supply, and the air compressors in each station in the single operation stations are used for air supply. For the air compressor which is not used for air supply, the air compressor can be in a shutdown state, namely, the no-load rate of the air compressor is 0, so that the no-load rate of the air compressor used for air supply only needs to be determined.

For the air compressors for supplying air, the loading pressure and the unloading pressure of each air compressor can be obtained firstly, and then the simulation operation of the air compressors is carried out through air compressor simulation operation software so as to obtain the loading time and the unloading time of each air compressor. Of course, the determination may be made by actual operation of the air compressors, for example, in actual operation of each air compressor, a period of time taken for the operating pressure to increase from the loading pressure to the unloading pressure is determined as the loading period of time, and a period of time taken for the operating pressure to decrease from the unloading pressure to the loading pressure is determined as the unloading period of time. And then, summing the determined loading time length and the unloading time length to obtain the period time length of each air compressor, and determining the ratio of the unloading time length to the period time length as the idle load rate of each air compressor.

Step 207: and determining a target operation scheme from the plurality of operation schemes based on the idle rate of each air compressor for air supply included in each determined operation scheme, wherein the target operation scheme refers to the operation scheme corresponding to the condition that the sum of the idle rates of each air compressor for air supply is minimum.

The total empty load rate of each air compressor used for supplying air, which is included in each operation scheme, is determined, and the empty load rate can reflect the unloading duration of the air compressor, namely the empty load duration of the air compressor, wherein the larger the empty load rate is, the longer the empty load duration of the air compressor is, the smaller the empty load rate is, and the shorter the empty load duration of the air compressor is. Therefore, in order to reduce the waste of electric energy and shorten the operation time of the air compressor caused by no load, the operation scheme corresponding to the minimum sum of no load rates can be selected from the multiple operation schemes, and the selected operation scheme is determined as the target operation scheme.

In the embodiment of the invention, a plurality of station yards which are communicated with each other are randomly combined to obtain a plurality of station yard combinations corresponding to the plurality of station yards, and each station yard combination can reflect a joint operation mode of the plurality of station yards. And then, determining the air supply mode of the combined operation station yard in each station yard combination according to the air consumption of each station yard and the air supply quantity of the air compressor in each station yard to obtain at least one operation scheme corresponding to each station yard combination, and summing the at least one operation scheme corresponding to each station yard combination to obtain a plurality of operation schemes corresponding to the plurality of station yards. In order to avoid waste of electric energy caused by large idle time of part of air compressors and increase of maintenance cost caused by increase of operation time of the air compressors in the operation process of the plurality of stations, for each of the plurality of operation schemes, the idle rate of each air compressor for supplying air can be determined based on the loading pressure and the unloading pressure of the air compressor in each station, and then the sum of the idle rates corresponding to each operation scheme is determined. And then, determining the running scheme with the smallest sum of the idle rate as a target running scheme so as to run the plurality of stations through the target running scheme. In addition, because the air compressor which is not used for air supply exists in the combined operation station yard included in the target operation scheme, the air compressor which is not used for air supply can be started when the air compressor which is used for air supply breaks down, and therefore the stability of the combined operation of the plurality of station yards is improved.
