Description

Technical Field

[0001] The present invention relates to the technical field of plant energy management, and more particularly, to a plant energy regulation system. Background Art

[0002] As a common energy regulation method, power rationing in industrial plants during high-temperature periods can effectively control the load on urban circuits. After receiving the power rationing quota, the plant will allocate it effectively to ensure the normal operation of the production line and office areas in the plant as much as possible. Among them, for high-temperature weather, the cooling demand consumes a large proportion of the plant's energy consumption. However, the management or regulation methods of the plant's cooling energy consumption are all based on the situation without power rationing and do not target this special power consumption scenario of high-temperature power rationing. Therefore, there is an urgent need for a regulation system for the electrical energy of the plant in this special power consumption scenario of high-temperature power rationing, so that it can reasonably regulate and control the power consumption of a large number of refrigeration equipment in the plant under extreme power consumption requirements.

[0044] Embodiment 1:

[0045] Before elaborating on the plant energy regulation system, it is necessary to briefly elaborate on the existing plant refrigeration system, as Figure 2 shown, which is a common plant refrigeration system, including multiple refrigeration links. Each refrigeration link includes at least one water tower, one air-conditioning main unit, and multiple air-conditioning sub-units that are matched with the air-conditioning main unit. The air-conditioning main unit is connected to multiple air-conditioning sub-units through multiple ventilation ducts. The water tower is used to dissipate heat from the air-conditioning main unit, thereby ensuring the refrigeration efficiency of the air-conditioning main unit.

[0046] As Figure 1 shown, this embodiment provides a plant energy regulation system, and the system includes:

[0047] A calculation module, the calculation module includes a meteorological data acquisition unit and a first calculation unit. The meteorological data acquisition unit is connected to an external meteorological network and is used to acquire the current temperature data. The temperature data will affect the refrigeration effect of the refrigeration equipment in the plant, so it is an important basis for energy regulation;

[0048] An adjustment module, the adjustment module includes a data retrieval unit and an adjustment unit. The data retrieval unit is connected to the operation and maintenance database of the plant and is used to retrieve the preset temperatures of multiple office areas in the plant from the operation and maintenance data. The adjustment unit is connected to multiple refrigeration links, office area temperature sensors, and key passage temperature sensors. The refrigeration link includes one air-conditioning main unit and multiple air-conditioning sub-units that cooperate with the air-conditioning main unit. By controlling the on / off of multiple air-conditioning sub-units, the temperature control of specific office areas can be realized;

[0049] Among them, the adjustment unit is used to, in the case of power limitation in the plant, adjust the operating power of multiple air-conditioning main units and the air-conditioning sub-units that are matched with the air-conditioning main units based on the refrigeration levels and the population in and out of multiple office areas, so as to reasonably adjust the actual temperatures of multiple office areas.

[0050] In this embodiment, the energy regulation system in the factory area divides the cooling demands of the factory area into priorities. For some high-priority office areas, such as biological laboratories, etc., their preset temperatures are not changed, and then the corresponding power consumption adjustments are made in sequence according to the levels. For office areas with low priorities, the operating power of the corresponding cooling equipment is appropriately reduced based on the number of people, or even the operation of the corresponding cooling equipment is shut down, so as to realize the energy consumption regulation management under the requirement of power limit.

[0051] Secondly, there are significant differences in the spatial layout between the factory area and traditional office buildings. Therefore, unified scheduling and adjustment cannot be achieved simply by increasing the preset environmental temperature threshold. It is necessary to sort the priorities of each area. Areas such as important production resource storage areas and important experimental areas are all areas with strict requirements for environmental temperature. Therefore, it is necessary to ensure the constancy of their temperatures first. Such places are classified as first-level office areas in this embodiment. Secondly, there are conventional office areas, which belong to areas where appropriate adjustment can be made.

[0052] Secondly, there are also significant differences in the activity patterns of personnel compared with traditional office buildings. The activity level of personnel is relatively high, that is, the amount of movement of personnel is large. Therefore, it is very necessary to adjust the working temperature of the corresponding office areas based on the activity level of the personnel within the area.

[0053] Secondly, the above method for adjusting the actual temperatures of multiple office areas includes step S100 and step S200.

[0054] Step S100: Obtain the current air temperature data through the meteorological data acquisition unit and retrieve the target temperatures of each office area in the factory area through the data retrieval unit. Then, retrieve the first cooling power consumption per unit square of each office area and key passage in the operation and maintenance database based on the current air temperature data and the target temperature, and calculate the total cooling power consumption corresponding to multiple office areas and multiple key passages based on the first cooling power consumption, the area of the office area, and the area of the key passage;

[0055] It should be noted that due to the architectural structure characteristics of the factory area, there are significant differences in the cooling power consumption required per unit square corresponding to different office areas. For example, multi-story buildings and single-story buildings, as well as the floor area of the building and the location of the office area in the building, etc., will all cause certain differences in the cooling demands of the office area under the same temperature conditions. It is necessary to conduct power consumption tests for each office area at different temperatures in advance or collect the power consumption data of the cooling equipment corresponding to each office area and key passage, and then statistically obtain the cooling power consumption per unit square of each office area and key passage at different temperatures and record it in the operation and maintenance database of the factory area.

[0056] Step S200: Obtain the current power rationing data, and retrieve the refrigeration power consumption quota from the power rationing data. If the total refrigeration power consumption is greater than 115% of the refrigeration power consumption quota, then adjust the operating power of multiple air-conditioning main units and the air-conditioning sub-units supporting the air-conditioning main units based on the refrigeration levels and population inflow and outflow of multiple office areas, thereby reasonably adjusting the actual temperatures of multiple office areas. It should be noted that in the case of no power rationing, each office area in the factory area is set with a target temperature and corresponding opening and closing time periods, so that the office areas and key passageways are maintained at a certain temperature. However, the power consumption limit brought about by high-temperature power rationing will result in the inability to meet the refrigeration requirements under normal circumstances. Therefore, it is necessary to meet the requirements in sequence according to the priority of the office areas, and exclude some office areas and key passageways with fewer people.

[0057] Secondly, the specific implementation method of adjusting the actual working temperatures of multiple office areas based on the refrigeration levels and population inflow and outflow of multiple office areas described in step S200 is as follows:

[0058] Step S210: Obtain the target temperatures, office area areas, and weather data corresponding to multiple first-level office areas, and find the second refrigeration power consumption per square unit of each first-level office area in the operation and maintenance database based on the target temperature and weather data corresponding to each first-level office area, and calculate the corresponding first-level refrigeration power consumption based on the second refrigeration power consumption and office area area corresponding to each first-level office area, thereby calculating the first operation and maintenance power corresponding to multiple first-level office areas;

[0059] Step S220: Obtain the current power rationing data, and calculate the second operation and maintenance power threshold based on the difference between the refrigeration power consumption quota in the power rationing data and the first operation and maintenance power;

[0060] Step S230: Obtain the monitoring images corresponding to multiple second-level office areas and the monitoring images of multiple key passageways within the first time period, and sequentially identify the number of office workers corresponding to each second-level office area and the number of people passing through each key passageway within the first time period, and exclude multiple invalid key passageways and second-level office areas based on a preset number threshold, thereby screening out multiple valid second-level office areas and valid key passageways;

[0061] Step S240: Retrieve the highest working temperature thresholds corresponding to multiple valid second-level office areas and valid key passageways, and correct the highest working temperature thresholds corresponding to the valid second-level office areas based on the total moving trajectory lengths of multiple moving targets within the valid second-level office areas, and calculate the second operation and maintenance power corresponding to multiple valid second-level office areas and valid key passageways based on the highest working temperature thresholds;

[0062] It should be noted that the maximum working temperature threshold is the preset maximum working ambient temperature, which is written into the operation and maintenance server in advance. At the same time, the maximum working temperature threshold should be appropriately reduced for the office areas with high human activity to improve the office experience.

[0063] Step S250: If the second operation and maintenance power is less than the second operation and maintenance power threshold, generate operation instructions for the corresponding air-conditioning main units and air-conditioning sub-units based on the maximum working temperature thresholds corresponding to multiple effective secondary office areas and effective key channels.

[0064] Step S260: If the second operation and maintenance power is greater than or equal to the second operation and maintenance power threshold, based on the difference between the second operation and maintenance power threshold and the second operation and maintenance power, increase the maximum working temperature threshold corresponding to the effective key channels in the non-sunshine direction or stop the operation of the air-conditioning main units corresponding to the effective key channels, so as to reduce the second operation and maintenance power until it is lower than the second operation and maintenance power threshold.

[0065] Secondly, the specific implementation method of increasing the maximum working temperature threshold corresponding to the effective key channels in the non-sunshine direction or stopping the operation of the air-conditioning main units and air-conditioning sub-units corresponding to the effective key channels based on the difference between the second operation and maintenance power threshold and the second operation and maintenance power described in step S260 is as follows:

[0066] Step S261: Obtain the current time node, retrieve the corresponding light parameters and the three-dimensional virtual model of the factory area, and then obtain at least one first wall surface in the non-sunshine direction. Construct a first radiation area based on the first wall surface. The width of the first radiation area is set based on the current temperature, and check whether there is an effective key channel in the first radiation area. If the proportion of the effective key channel in the first radiation area is greater than 55%, it is determined as the second key channel;

[0067] Step S262: Reduce or even turn off the operating power consumption of the air-conditioning sub-units and / or air-conditioning main units corresponding to the second key channels until the adjusted second operation and maintenance power is less than the second operation and maintenance power threshold.

[0068] Secondly, the specific implementation method of correcting the maximum working temperature threshold corresponding to the effective secondary office area based on the total length of the movement trajectories of multiple moving targets in the effective secondary office area described in step S240 is as follows:

[0069] Step S241: Dispatch multiple monitoring videos at different angles in an effective secondary office area, identify the human targets in each monitoring video based on the image feature extraction algorithm of the shape class, and eliminate the duplicate human targets in multiple monitoring videos based on the scene coordinates and target human features, so as to obtain the number of human targets in the effective secondary office area;

[0070] Step S242: construct multiple moving point monitoring coordinates based on the road distribution in the valid secondary office area, and when the person target in the monitoring video moves to the corresponding moving point monitoring coordinates, mark the moving path corresponding to the person target as the first valid path;

[0071] Step S243, obtaining multiple first valid paths collected in the first time period, and eliminating first valid paths whose lengths are less than a minimum threshold, thereby obtaining multiple second valid paths;

[0072] Step S244: based on the end vector direction of each second valid path and the coordinates of the doorway of the valid secondary office area, eliminate the second valid paths used to indicate that the paths have left the valid secondary office area within the first time period, thereby obtaining a plurality of third valid paths;

[0073] Step S245: Calculate the average activity path length corresponding to the average effective secondary office area based on the number of third effective paths and the total length of multiple third effective paths;

[0074] Step S246: based on the fluctuation of the number of target people in the effective secondary office area in the first time period, calculate the average total number of people in the effective secondary office area in the first time period;

[0075] Step S247: Calculate the first activity level of the effective secondary office area through a weighted algorithm based on the ratio between the number of the third effective paths and the average total number of people and the average activity path length;

[0076] Step S248: Correct the maximum operating temperature threshold corresponding to the valid secondary office area based on the first activity level.

[0077] Effective activity tracks within the office area should meet the following requirements:

[0078] 1. The moving distance within a certain period of time must reach the preset distance value to prevent misjudgment of activity due to small-scale activities at the workstation;

[0079] 2. If you leave the office area during this period, it will be considered an invalid trajectory, that is, the activity trajectory of the person leaving will not be counted as an evaluation parameter for the activity of the office area.

[0080] Secondly, the implementation method of correcting the maximum operating temperature threshold corresponding to the effective secondary office area based on the activity level in step S248 is:

[0081] Step S2481: Retrieve the activity threshold corresponding to the current valid secondary office area in the operation and maintenance database. The activity threshold is determined based on the employment staff workstation table. By using the employment staff workstation table, the long-term resident number corresponding to each office area can be determined, and then the activity thresholds corresponding to different numbers (different office areas) can be determined.

[0082] Step S2482: If the first activity is greater than the activity threshold, reduce the highest working temperature threshold corresponding to the valid secondary office area based on the difference between the first activity and the activity threshold.
