Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application discloses an electricity load analysis system, which is shown in fig. 1, and comprises:
and the building data acquisition module is used for acquiring building layout data of the building.
Specifically, the building layout data may include floor data, functional area division data, and functional area of each functional area of the building, where the main data is the functional area division data and the functional area, where the functional area division data includes division conditions of each functional area, and includes types of each functional area, for example, types of the functional areas include a hall, a conference room, an office area, a rest area, and the like, and obtaining the building layout data makes a mat for calculating how many lighting devices and other electric devices are needed in the building in the following.
And the illumination density matching module is used for matching the illumination power density of each functional area in the building by using the building layout data according to a preset illumination power density standard.
Specifically, different types of functional areas have different requirements on illumination, for example, illumination of office areas is required to meet the illumination degree that human eyesight is not damaged when people work, while corridor illumination is required to be relatively low, only ensuring that people can see clearly at night, so that illumination power density of each functional area is matched in pre-generated illumination power density standards, wherein the illumination power density standards can be standard specifications such as building illumination design standard and industrial and civil power supply and distribution design manual.
And the electric equipment matching module is used for matching the number, the type and the power of the electric equipment in each functional area in the building by utilizing the building layout data according to the preset electric equipment layout standard.
Specifically, besides lighting power consumption, power consumption of each electric equipment in a building is further provided, different types and numbers of electric equipment can be installed in different functional areas, for example, office areas comprise printers and a large number of computers, a hall can comprise printers, paper shredders and a small number of computers, each type of area comprises a type of electric equipment, the number of the electric equipment and the power of each electric equipment are stored in a preset electric equipment layout standard, and therefore the number, the type and the power of all the electric equipment in each functional area can be matched in the electric equipment layout standard.
The electric equipment layout standard can record that an office area comprises a computer with the power of 400W every 1.5 square meters, a printer with the power of 500W every 200 square meters and a water dispenser with the power of 300W every 60 square meters, for example, according to the electric equipment layout standard, how many electric equipment are in each functional area can be calculated according to the area of the functional area, and preparation is made for the electric equipment load of the functional area to be calculated subsequently.
It should be noted that, the electric equipment layout standard is a standard corresponding to a building needing to be calculated at present, and the electric equipment layout standard is obtained by statistics according to electric equipment required by planning of the current building, namely, when the electric loads of different buildings are analyzed, the electric equipment layout standard is adopted, the electric equipment layout standard can be set according to building layout data and use requirements of actual buildings, or electric equipment in the current building is directly counted to obtain, so that the current building can obtain the total load close to the actual electric loads.
It should be understood that the electric equipment does not include a basic lighting device, the basic lighting device is calculated by using the foregoing lighting power density standard alone, the result is more reasonable, and the special lighting device can be generalized to electric equipment, for example, a spotlight for a stage, etc., and the basic lighting device is a lighting device for illuminating an inner space of a building for a user.
And the electricity utilization rule acquisition module is used for acquiring the electricity utilization rule of each functional area.
Specifically, the electricity usage rule is to infer the electricity usage rule of the building according to the usage of the building, for example, the working time of the residential building on the working day, the electricity consumption is small, the electricity consumption at night and six days after working is high, the electricity consumption of the office building is large, the electricity consumption of the office building is small after working and rest, and meanwhile, the maximum electricity consumption is affected according to the number of fully loaded people in the building, so the electricity usage rule can specifically comprise the people arrival rate and the work and rest rule predicted by each functional area.
Specifically, because personnel in the building flow, all personnel in the building are difficult to ensure that all electric equipment and lighting equipment in the building are needed, the personnel taking the sentry rate and the work and rest law into consideration comprehensively, so that the human factors of the users are taken into consideration in the analysis of the electric load, the analysis of the maximum use amount of hardware facilities is avoided, the total electric load of the building is estimated to be too high, and the electric load closer to the actual electric load can be obtained.
The personnel on duty rate is used for showing how many people are in the building every day, and the work and rest law is used for showing how many hours are in the building every day.
It should be noted that the electricity usage rule is a preset known amount.
The load calculation module is used for obtaining the lighting load and the electric equipment load of each functional area by utilizing the building layout data, the electricity utilization rule of each functional area, the lighting power density, the number, the type and the power of the electric equipment;
and the total load calculation module is used for obtaining the total electricity consumption load of the building by utilizing the lighting load and the electric equipment load of each functional area.
Specifically, the area, the illumination power density and the electricity utilization rule of each functional area in the building layout data are utilized to couple, the illumination load of each functional area can be obtained, the electricity utilization rule of each functional area, the number, the type and the power of the electric equipment are utilized to couple, the electric equipment load of each functional area can be obtained, finally, the illumination load and the electric equipment load of each functional area are comprehensively calculated by utilizing the total load calculation module, and the total electricity utilization load of the whole building is obtained, which is more close to reality and more accurate according to the illumination power density standard, the electric equipment layout standard, the building layout data and the electricity utilization rule calculation.
It can be understood that the power transmission equipment such as transformers with similar building design quota can be subjected to total power consumption load, so that excessive design redundancy of the equipment is avoided, and the quota is wasted.
Therefore, the embodiment of the application specifically divides the building into a plurality of functional areas, considers different electricity utilization conditions of different areas by matching with a predesigned illumination power density standard and an electric equipment layout standard, comprehensively considers the influence of electricity utilization rules brought by human factors on electricity utilization loads, comprehensively considers the total electricity utilization load of the building which is closer to reality and more accurate, provides guidance for the subsequent design of power transmission equipment such as transformers, power transmission wires and the like, and avoids resource waste caused by redundant arrangement of the power transmission equipment.
The lighting power density standard and the electric equipment layout standard can be changed according to actual application requirements, for example, the corresponding relation between the lighting power density standard and the functional area is changed, specific parameters are adjusted and added, equipment is newly added, and the like.
The embodiment of the application discloses a specific electricity load analysis system, and compared with the previous embodiment, the embodiment further describes and optimizes the technical scheme. Specific:
specifically, the load calculation module may include a lighting area dividing unit, a lighting load calculating unit, a lighting load adding unit, an electric equipment dividing unit, an equipment load calculating unit, and an equipment load adding unit; wherein, the liquid crystal display device comprises a liquid crystal display device,
the illumination area dividing unit is used for dividing a dynamic illumination area with illumination time changing along with a normally open illumination area with illumination time not changing along with time according to the classification of each functional area.
For example, a hall in a company may not be illuminated by sunlight, so long-time illumination is required, the illumination is not changed with time, the illumination of the functional area belongs to a normally-open illumination area with the illumination time not changed with time, the area is counted to obtain the normally-open illumination area, the illumination in the office area is dynamically switched on and off along with the departure or the entering of office staff, the illumination of the functional area belongs to a dynamic illumination area with the illumination time changing with time, and the area is counted to obtain the area of the dynamic illumination area.
Specifically, each functional area is divided, because two lighting use cases may exist in one area, and by classifying and calculating the lighting loads of the functional areas according to the lighting time length, the influence of the artificial factors on the loads can be comprehensively considered.
The lighting load calculation unit is used for obtaining the lighting load of the building by utilizing the dynamic lighting area, the normally-open lighting area, the lighting power density, the personnel on-duty rate and the work and rest law of each functional area.
Specifically, according to the illumination load calculation formula, the illumination load of each functional area can be synthesized to obtain the illumination load of the building; wherein, the liquid crystal display device comprises a liquid crystal display device,
the illumination load calculation formula is:
ΔLL＝A(x)*LPD(x)*H(t1)*R(t2)+A(y)*LPD(y)；
where Δll denotes the lighting load of the building, a (x) = Σa (x=1, x=n), a (x) denotes the dynamic lighting area, x denotes the initial value, n denotes the kind of dynamic lighting area, such as A1 denotes the total area of the 1-type dynamic lighting area, LPD (x) = Σlpd (x=1, x=n), LPD (x) denotes the lighting power density of various dynamic lighting areas, H (t 1) = Σh (x=1, m=365), H (t 1) denotes the person-to-job ratio, m denotes the maximum value, R (t 2) = Σr (i=1, h=24), R (t 2) denotes the rule of rest, H denotes the maximum value, a (y) = Σa (y=1, y=j), a (y) denotes the area of the normally open lighting area, j denotes the kind of the normally open lighting area, LPD (y) = Σlpd (y=1, y=j) denotes the normally open lighting power density of various lighting areas.
It should be noted that, in the above-mentioned illumination load calculation formula, each functional area in the whole building uses unified personnel on-duty rate and work and rest law, of course, in practical application, personnel on-duty rate and work and rest law may also be collected for each area, and each functional area calculates by using corresponding personnel on-duty rate and work and rest law respectively.
It will be appreciated that if there is no dynamic illumination area or no normally-open illumination area within a functional area, the corresponding value may take on 0; the lighting power density and electricity usage rules of the different functional areas are different, so that each functional area calculates the respective lighting load.
The electric equipment dividing unit is used for dividing dynamic electric equipment with the electricity duration changing along with time and normally open electric equipment with the electricity duration not changing along with time according to the types of the electric equipment in each functional area.
For example, a computer, a printer and other devices can only work when a person uses the device, the electricity consumption time of the device changes along with the time, the user can close the device, and the device belongs to dynamic electric equipment, while the devices such as a water dispenser, an air freshener and the like can be kept on for a long time and do not change along with the time, so the device belongs to normally-open electric equipment.
Specifically, each functional area is divided, because two kinds of electric equipment can exist in one area, and the influence of artificial factors on the load can be comprehensively considered by classifying and calculating the electric equipment loads of the functional areas according to the electricity consumption time length.
And the equipment load calculation unit is used for obtaining the electric equipment load of each functional area by using the personnel arrival rate, the work and rest law, the quantity and the power of the dynamic electric equipment and the normally-open electric equipment of each functional area.
Specifically, according to an electric equipment load calculation formula, the electric equipment load of each functional area can be synthesized to obtain the electric equipment load of the building; wherein, the liquid crystal display device comprises a liquid crystal display device,
the load calculation formula of the electric equipment is as follows:
ΔEL＝EP(x)*H(t1)*R(t2)+EP(y)；
where Δel represents the load of the electric device of the building, EP (x) = Σep (x=1, x=b) represents the power of the dynamic electric device, b represents the kind of the dynamic electric device, EP (y) = Σep (y=1, y=k), EP (y) represents the power of the normally open electric device, and k represents the kind of the normally open electric device.
It should be noted that, in the above electric equipment load calculation formula, the unified personnel arrival rate and work and rest law are used in the whole building, and of course, in practical application, the personnel arrival rate and work and rest law can also be collected for each area, and according to the functional area where the electric equipment is located, corresponding personnel arrival rate and work and rest law are used for calculation respectively.
It can be understood that if there is no dynamic electric equipment or normally open electric equipment in one functional area, the corresponding value can be 0; the number, the type and the electricity usage rules of the electric equipment in different functional areas are different, so that each functional area calculates the load of the respective electric equipment.
Specifically, the total power consumption load of one functional area can be expressed as follows:
ΔTL＝ΔLL+ΔEL＝[A(x)*LPD(x)+EP(x)]*H(t1)*R(t2)+A(y)*LPD(y)+EP(y)。
where Δtl represents the total load of electricity used by the building.
Specifically, the lighting load and the electric equipment load of each functional area are integrated, so that the total electricity consumption load of the whole building can be obtained.
The functional area of the office building, the division of the lighting equipment and the electric equipment can be as shown in the following table 1:
