[0116] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0117] As Figure 1 shown, a coastal refinery emergency scheduling method according to an embodiment of the present invention includes:

[0118] Step S1: Based on the inspection of the crude oil scheduling information of the coastal refinery emergency scheduling request, determine the abnormal information of the crude oil scheduling of the scheduling event;

[0119] Step S2: Based on the abnormal information of the crude oil scheduling of the scheduling event, adjust the crude oil scheduling plan;

[0120] Step S3: Based on the adjustment of the crude oil scheduling plan, obtain a new crude oil scheduling plan.

[0121] In step S1, the inspection of the crude oil scheduling information based on the coastal refinery emergency scheduling request to determine the abnormal information of the crude oil scheduling of the scheduling event includes:

[0122] Step A1: Collect all scheduling event information within the scheduling cycle corresponding to the crude oil scheduling information;

[0123] Step A2: Based on the simulation deduction results of each scheduling event one by one, determine the abnormal information of the crude oil scheduling of the scheduling event.

[0124] In step A1, the information content included in the crude oil scheduling information of the coastal refinery emergency scheduling request is shown in Table 1;

[0125] Table 1

[0126]

[0127] As Figure 2 shown, the crude oil scheduling route of the coastal refinery includes cruise ships (referring to several cruise ships), docks (referring to several docks), dock tank farms, in-plant tank farms (referring to in-plant tank farms), and atmospheric and vacuum distillation units. The crude oil scheduling route: Sea-transported crude oil is transported from cruise ships to docks, then to dock tank farms, and then from the dock tank farms to in-plant tank farms. The sea-transported crude oil forms mixed crude oil after mixing in the in-plant tank farms, and the mixed crude oil is transported to the atmospheric and vacuum distillation units. On this crude oil scheduling route, in the scenario where the load of the atmospheric and vacuum distillation unit changes, it may cause the tank inventory in the tank farm information to exceed the preset upper and lower limits, resulting in abnormal crude oil scheduling of the scheduling event. Based on this, it is necessary to adjust the scheduling plan of the scheduling event with abnormal crude oil scheduling. First, it is necessary to determine the specific information of the abnormal crude oil scheduling of the scheduling event, which is the purpose of step A1.

[0128] In step A2, the determination of the abnormal information of the crude oil scheduling of the scheduling event based on the simulation deduction results of each scheduling event one by one includes:

[0129] Step B1: During the scheduling period, simulate and deduce each scheduling event one by one until the simulation and deduction of all scheduling events are completed. The inspection of the simulation and deduction includes:

[0130] The first inspection: Check whether the upper and lower limits of the tank inventory are breached;

[0131] The second inspection: Check whether the tank receipts and deliveries do not meet the static desalting time; whether the tank receipts and deliveries do not meet the receipt and delivery conditions. The non - meeting situations include over - intake, over - outtake, and simultaneous intake and outtake;

[0132] The third inspection: Check whether there is a conflict in the oil unloading at the terminal;

[0133] Step B2: Determine the crude oil scheduling exception information of the scheduling event based on the result of the simulation and deduction. The result of the simulation and deduction is the information corresponding to the case where the first inspection result is "yes", and / or the information corresponding to the case where the second inspection result is "yes", and / or the information corresponding to the case where the third inspection result is "yes".

[0134] In Step B1, during the one - by - one simulation and deduction of all scheduling events within the scheduling period, conduct the one - by - one simulation and deduction in the order of the time sequence of the scheduling events within the scheduling period. The time of the scheduling event comes from the scheduling event information. This method of sequential one - by - one simulation and deduction is only an exemplary scheme with the optimal simulation and deduction efficiency (in terms of speed) in the present invention. In other embodiments of the present invention, other schemes can also be used for simulation and deduction, as long as all scheduling events within the scheduling period are completed for simulation and deduction.

[0135] In Step B2, the result of the simulation and deduction is the information corresponding to the case where the first inspection result is "yes", and / or the information corresponding to the case where the second inspection result is "yes", and / or the information corresponding to the case where the third inspection result is "yes". That is, after the simulation and deduction, there are crude oil scheduling exceptions in the scheduling event. Then, determine that "checking the breach of the upper and lower limits of the tank inventory", and / or "checking that the tank receipts and deliveries do not meet the static desalting time; and / or the tank receipts and deliveries do not meet the receipt and delivery conditions", and / or "checking the conflict in the oil unloading at the terminal" as the crude oil scheduling exception information of the scheduling event;

[0136] When the result of the simulation and deduction is that the first inspection result is "no", the second inspection result is "no", and the third inspection result is "no", that is, there are no crude oil scheduling exceptions in the scheduling event.

[0137] In Step S2, when adjusting the crude oil scheduling plan, if there is crude oil scheduling exception information for multiple scheduling events within the scheduling period, the adjustment includes:

[0138] Sort according to the time sequence of the scheduling events within the scheduling period, and repeatedly execute the two steps of adjustment and simulation and deduction until there is no crude oil scheduling exception information in the crude oil scheduling plan;

[0139] Wherein, during the adjustment process, the adjusted crude oil scheduling plan of the current scheduling event is used as the crude oil scheduling plan of the next scheduling event, and the adjustment of the current scheduling event does not cause abnormal crude oil scheduling;

[0140] This method of adjusting in a sequential cycle within a scheduling period is only exemplified by the present invention. It is a solution with the best adjustment efficiency (in terms of speed and error rate) when there are multiple scheduling events and abnormal crude oil scheduling information. Other solutions can also be used for adjustment in other embodiments of the present invention, as long as it is ensured that the new crude oil scheduling plan obtained after the adjustment does not contain abnormal crude oil scheduling information.

[0141] In step S2, the crude oil scheduling plan is adjusted based on the abnormal crude oil scheduling information of the scheduling event, including:

[0142] Step C1: modifying the long-distance pipeline transmission event based on the abnormal crude oil scheduling information of the scheduling event;

[0143] Step C2, performing a first check on the modified long-distance pipeline transmission event as the adjusted scheduling plan;

[0144] Step C3: based on the first verification result, whether to judge whether to shut down the long transmission pipeline;

[0145] Step C4: based on the judgment result, selecting whether to time-shift the transmission event of the long-distance pipeline;

[0146] Step C5, performing a second check on the post-shift transmission event as the adjusted scheduling plan;

[0147] Step C6: based on the second verification result, select whether to borrow oil from the same tank farm;

[0148] Step C7, performing a third check on the oil storage event in the same tank area after borrowing oil from the same tank area as the adjusted scheduling plan;

[0149] Step C8: based on the third verification result, select whether to borrow oil from the commercial storage tank;

[0150] Step C9, performing a fourth check on the event of the commercial storage tank storing oil after the commercial storage tank borrows oil as the adjusted scheduling plan;

[0151] Step C10: based on the fourth verification result, selecting whether to adjust the oil unloading speed of the tanker;

[0152] Step C11, performing a fifth check on the oil unloading speed event after the oil unloading speed adjustment as the adjusted scheduling plan;

[0153] Step C12: Based on the fifth verification result, the adjustment of the crude oil scheduling plan is finished.

[0154] Wherein, the first check, the second check, the third check, the fourth check and the fifth check all include the first check, the second check and the third check;

[0155] And in the above steps:

[0156] The modification of the long-distance pipeline transmission event refers to the violation of the upper and lower limits of the in-plant tank storage caused by the abnormal atmospheric and vacuum pressure. The abnormality of the in-plant tank storage exceeding the upper and lower limits caused by the original transmission event can be eliminated by changing the starting point or end point of the long-distance pipeline transmission event; the atmospheric and vacuum pressure formula modification eliminates the abnormality of the processing time properties or related in-plant tank storage by modifying the source tank and oil transmission rate / ratio in the atmospheric and vacuum pressure processing event;

[0157] The time shift refers to the abnormality of the tank storage in the plant exceeding the upper and lower limits caused by abnormal atmospheric and vacuum pressure. The abnormality of the tank storage in the plant can be eliminated by time shifting the overall transmission event, and then other abnormalities caused by time shift (such as abnormal tank storage or payment conditions in the terminal tank area) can be adjusted. The time shift strategy will cause the interruption of long-distance pipeline transmission, so it is only applicable to scenarios where long-distance pipeline transmission can be interrupted;

[0158] Borrowing oil from the same tank farm refers to changing the starting point or end point of a transmission event to affect the storage and transmission conditions of related tanks and eliminate abnormal storage or transmission;

[0159] The commercial tank area oil borrowing refers to the replenishment of tank storage in the terminal tank area through the transfer of newly added commercial tank areas to eliminate tank storage abnormalities;

[0160] The adjustment of the oil tanker unloading speed refers to changing the oil tanker unloading speed to eliminate abnormal tank storage in the terminal tank area, which may cause delays for the tanker.

[0161] In step C1, the modification of the long-distance pipeline transmission event includes:

[0162] Step D1, identifying the time period to be adjusted and the minimum transmission amount to be adjusted corresponding to the scheduling event;

[0163] Step D2, selecting a first alternative oil tank for the destination oil tank according to a first preset condition;

[0166] Step D5: based on the sixth verification result, selecting whether to use the first long-distance pipeline replacement transmission adjustment result as a modified long-distance pipeline transmission event;

[0170] The first alternative oil tank has the same or similar oil type as the crude oil tank;

[0171] The first alternative oil tank is in an available state during the borrowed period and does not violate the static desalination constraints and receipt and payment conditions;

[0172] After the oil volume of the first alternative oil tank is borrowed, its tank inventory meets the preset upper and lower limit requirements.

[0173] In step D5, based on the sixth verification result, selecting whether to use the first long-distance pipeline alternative transmission adjustment result as the modified long-distance pipeline transmission event includes:

[0174] Step D51: When the sixth verification result shows that the first inspection result is no, the first inspection result is no, and the third inspection result is no, that is, when there is no abnormal crude oil scheduling situation, select the first long-distance pipeline alternative transmission adjustment result as the modified long-distance pipeline transmission event (that is, obtain a new crude oil scheduling plan);

[0175] Step D52: When the sixth verification result shows that the first inspection result is yes, and / or the first inspection result is yes, and / or the third inspection result is yes, that is, when there is an abnormal crude oil scheduling situation, screen the second alternative oil tank for the starting oil tank and the terminal oil tank according to the second preset condition;

[0176] Step D52': Use the second alternative oil tank as the second long-distance pipeline alternative transmission adjustment result;

[0177] Step D52": Use the second long-distance pipeline alternative transmission adjustment result as the adjusted scheduling plan and conduct the seventh verification;

[0178] Step D52''': Based on the seventh verification result, select whether to use the second long-distance pipeline alternative transmission adjustment result as the modified long-distance pipeline transmission event;

[0179] Among them, the seventh verification includes the first inspection, the first inspection, and the third inspection;
