Description

Technical Field

[0001] This invention relates to the field of port energy management technology, and in particular to a method for calculating the energy consumption of a single vessel at a specialized dry bulk cargo terminal in a port. Background Technology

[0002] With the growth of global trade and the deepening of the "green port" concept, port energy consumption and carbon emission management have increasingly become a focus of industry attention. As a key unit of port energy consumption, the accuracy of energy consumption metering at dry bulk terminals is directly related to operating cost accounting, energy-saving measure assessment, and carbon footprint tracking.

[0003] Currently, port energy consumption management largely focuses on enterprise-level macro-statistics, which involves monthly or annually calculating total electricity and fuel consumption and then dividing by total throughput to obtain a rough "energy consumption per ton" indicator. The shortcomings of this method are obvious:

[0004] (1) Low accounting accuracy: It is impossible to accurately calculate the actual energy consumption cost of a single ship, which is not conducive to refined management and customer settlement;

[0005] (2) Lack of process analysis: It is impossible to identify which specific stage of energy consumption occurs (such as unloading, conveying, stacking and reclaiming), making it difficult to locate high energy consumption points, and energy-saving renovation lacks data support;

[0100] In this embodiment, to clarify the logical basis of the above calculation steps and the scope of energy consumption statistics, the operation process of dry bulk cargo terminals, the core idea of ​​single-ship energy consumption calculation, and the composition of energy consumption are explained in detail:

[0101] The typical operational process for specialized dry bulk cargo terminals (specialized terminals for iron ore, coal, grain, etc.) at ports is as follows:

[0102] Unloading operations: Ship arrives at port → Unloading (unloading machine and cleaning equipment) → Horizontal transport (belt conveyor) → Storage (stack reclaimer) → Stockyard;

[0103] Ship loading operation: stockyard → material reclaiming (stack reclaimer) → horizontal transport (belt conveyor) → loading (ship loader) → ship departure.

[0104] Single-ship energy consumption calculations need to revolve around this process. The core idea of ​​single-ship energy consumption calculations at dry bulk terminals is to identify and measure the energy consumption of all equipment and systems used to complete ship loading and unloading operations, and accurately attribute it to the ship's operations.

[0105] The energy consumption of a single vessel at a dry bulk terminal mainly includes the following components:

[0106] (1) Energy consumption of direct operating equipment;

[0107] Energy consumption of unloading equipment: Energy consumption of bridge grab unloaders, chain bucket unloaders, and gantry unloaders during unloading operations.

[0108] Energy consumption of loading equipment: Energy consumed by ship loaders, mobile ship loaders, etc. during the loading operation.

[0109] Energy consumption of stacker-reclaimer equipment: The energy consumed by bucket wheel stacker-reclaimers, reclaimers, stackers, etc. during stacking and reclaiming operations in the rear stockyard.

[0110] (2) Energy consumption of networked belt conveyor systems;

[0111] This includes the energy consumption of all horizontal and inclined belt conveyors and their drive motors during material transport, which is the most complex and important part of dry bulk terminal calculations.

[0112] (3) Energy consumption of auxiliary systems;

[0113] This mainly includes the energy consumption of the dust removal system and the lighting system.

[0114] Dust removal system energy consumption: The energy consumed by equipment such as water spraying systems and dry dust collectors used in loading and unloading ships, material conveying and stockpile stacking and reclaiming operations.

[0115] Lighting system energy consumption: The energy consumed by lighting equipment and lamps used in loading and unloading ships, material conveying and stockpile operations at the wharf.

[0116] (4) Energy consumption of the cleaning equipment;

[0117] This mainly includes the energy consumed during the cleaning operation using excavators, loaders, etc.

[0118] Using the calculation method described in this application, terminal managers can clearly see that the ship's operations consumed approximately 75,700 kWh of electricity and 0.2 tons of diesel, totaling 9.517 tce of energy consumption. Of this, direct operating equipment accounted for 64.57%, belt conveyor systems accounted for 30.82%, auxiliary systems accounted for 1.56%, and tank cleaning equipment accounted for 3.06%. The energy consumption per 10,000 tons was 0.595 tce / 10,000 tons. These data provide a solid foundation for the terminal company's refined energy management.

[0119] Example 2

[0120] This embodiment provides an electronic device for performing the above-described single-ship energy consumption calculation method, including a memory, a processor, and a computer program stored in the memory and capable of running on the processor.

When the processor executes the computer program, it specifically implements the following process:

[0122] Through the data acquisition interface, the target vessel's operation time window, total operation volume W, and relevant energy consumption data of the direct operation equipment, belt conveyors, auxiliary systems, and tank cleaning equipment involved in the operation are obtained.

[0123] Subsequently, the built-in computing engine is invoked to execute the calculation steps of Example 1, including:

[0124] E is calculated based on the electrical energy data of the directly operating equipment. z ;

[0125] Calculate the allocated energy consumption E based on the ratio of the total power consumption to the service time of the belt conveyor. x ;

[0126] The allocation coefficient is dynamically calculated based on the number of vessels operating simultaneously, and then the energy consumption E of the auxiliary system is calculated. f ;

[0127] Calculate the energy consumption E of the tank cleaning equipment based on diesel consumption. q ;

[0128] Finally, the total energy consumption E of the target ship is obtained by summing up the results. ship And calculate the energy efficiency index e ship .

[0129] Example 3

[0130] This embodiment provides a computer-readable storage medium on which a computer program is stored.

[0131] When a computer program is read and executed by a processor, the following operations are performed:

[0132] The system automatically queries and loads the target ship's operational information and raw energy consumption data from the data source, constructs a single ship energy consumption calculation model, and executes the energy consumption calculation steps of Example 1 by calling the corresponding calculation module.

[0133] Finally, the total energy consumption E of the target ship is generated and output. ship and energy efficiency index e ship Structured data results;
