Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building energy conservation, in particular to an analysis device for building energy consumption and carbon emission intensity of a new building energy system. Background Technique
[0002] With the application of distributed energy systems and energy storage systems in buildings and the popularization of new energy vehicles, the structure of the integrated energy system of buildings has become more and more complex. Buildings have changed from simple electricity loads to an integrated system of sources, storage, and loads. At the same time, buildings provide electrical energy for new energy vehicles, which should also be distinguished from the electrical energy consumed by the buildings themselves to maintain their own operation. At present, conventional building carbon energy consumption monitoring devices only monitor the electricity consumption of the main power supply. The monitoring of distributed energy, energy storage, and charging piles are all independent systems. Therefore, when analyzing the building energy consumption situation, only the electricity consumption of the main power supply is considered, and the parts of distributed energy generation and new energy vehicle charging are not considered, resulting in the analysis result being unable to truly reflect the energy consumption situation of the building itself.
[0003] Therefore, the actual energy consumption of buildings can no longer be directly reflected by the electricity consumption of municipal power. At this time, a special device is needed to accurately analyze the energy consumption intensity and carbon emission intensity of buildings, serving as the data basis for building energy conservation and carbon reduction transformation. Content of the Utility Model
[0004] The utility model aims to solve at least one of the technical problems in the related technologies to some extent. For this reason, an object of the utility model is to provide an analysis device for building energy consumption and carbon emission intensity of a new building energy system, which can accurately and comprehensively calculate the energy consumption intensity and carbon emission intensity of the new building.
[0005] The technical solution adopted by the utility model is as follows:
[0006] In a first aspect, the present utility model provides a device for analyzing building energy consumption and carbon emission intensity of a new type of building energy system. The new type of building energy system includes building conventional energy-consuming equipment, municipal power-consuming equipment, a distributed energy system, an energy storage system, and new energy vehicle charging equipment. Among them, the device includes: a first smart meter, arranged at the access point of the municipal power-consuming equipment, for collecting the municipal power consumption; a second smart meter, arranged at the access point of the distributed energy system, for collecting the power generation of the distributed energy system; a third smart meter, arranged at the access point of the energy storage system, for collecting the power consumption of the energy storage system; a fourth smart meter, arranged at the access point of the building conventional energy-consuming equipment, for collecting the power consumption of the building conventional energy-consuming equipment; a fifth smart meter, arranged at the access point of the new energy vehicle charging equipment, for collecting the power consumption of the new energy vehicle charging pile; a switch, connected to the first smart meter, the second smart meter, the third smart meter, the fourth smart meter, and the fifth smart meter respectively through wired communication; an engineer station, connected to the switch through wired or wireless communication, for collecting the power consumption conditions of the first smart meter, the second smart meter, the third smart meter, the fourth smart meter, and the fifth smart meter to analyze the building energy consumption intensity information and carbon emission intensity information of the new type of building energy system.
[0007] Among them, it further includes: a cloud platform, connected to the switch through wireless communication, for collecting the power consumption conditions of the first smart meter, the second smart meter, the third smart meter, the fourth smart meter, and the fifth smart meter to analyze the building energy consumption intensity information and carbon emission intensity information of the new type of building energy system.
[0008] Among them, the first smart meter, the second smart meter, the third smart meter, the fourth smart meter, and the fifth smart meter are all installed on the building power distribution line.
[0009] The beneficial effects of the present utility model are:
[0010] The present utility model sets multiple smart meters at the ends of multiple sub-power-consuming (or power-supplying) systems of the new type of building energy system to collect the power consumption or power generation of the multiple sub-power-consuming (or power-supplying) systems, and transmits the power information collected by the multiple smart meters to the engineer station through the switch for data analysis, so as to obtain the building energy consumption intensity information and carbon emission intensity information of the building. The present invention comprehensively monitors and reasonably calculates the building energy system, which can avoid the situation that the calculation result of the building energy consumption intensity is falsely high due to the large charging volume of the building energy system for new energy vehicles, and the situation that the building energy consumption intensity is falsely low due to the large access of distributed photovoltaics. Description of the Drawings
[0011] Figure 1It is a schematic structural diagram of an embodiment of a building energy consumption and carbon emission intensity analysis device for a new building energy system of the present utility model. Detailed implementation manners
[0012] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.
[0013] Please refer to Figure 1 , Figure 1 It is a schematic structural diagram of an embodiment of a building energy consumption and carbon emission intensity analysis device for a new building energy system of the present utility model. The new building energy system includes building conventional energy-consuming equipment (not labeled in the figure), municipal power-consuming equipment (not labeled in the figure), a distributed energy system (not labeled in the figure), an energy storage system (not labeled in the figure), and new energy vehicle charging equipment (not labeled in the figure).
[0014] As Figure 1 shown, the device includes a first smart meter 1, a second smart meter 2, a third smart meter 3, a fourth smart meter 4, a fifth smart meter 5, a switch 6, and an engineer station 7.
[0015] Among them, the first smart meter 1, the second smart meter 2, the third smart meter 3, the fourth smart meter 4, and the fifth smart meter 5 are all installed on the building power distribution line.
[0016] The first smart meter 1 is set at the access point of the municipal power-consuming equipment for collecting the municipal power consumption.
[0017] The second smart meter 2 is set at the access point of the distributed energy system for collecting the power generation of the distributed energy system.
[0018] The third smart meter 3 is set at the access point of the energy storage system for collecting the power consumption of the energy storage system.
[0019] The fourth smart meter 4 is set at the access point of the building conventional energy-consuming equipment for collecting the power consumption of the building conventional energy-consuming equipment.
[0020] The fifth smart meter 5 is set at the access point of the new energy vehicle charging equipment for collecting the power consumption of the new energy vehicle charging pile.
[0021] The switch 6 is respectively connected to the first smart meter 1, the second smart meter 2, the third smart meter 3, the fourth smart meter 4, and the fifth smart meter 5 through a wired communication method.
[0022] The engineer station 7 is connected to the switch 6 through wired or wireless communication methods, and is used to collect the electricity consumption of the first smart meter 1, the second smart meter 2, the third smart meter 3, the fourth smart meter 4, and the fifth smart meter 5 to analyze the building energy consumption intensity information and carbon emission intensity information of the new building energy system.
[0023] When the engineer station 7 collects the information of the above five smart meters, the collection interval is not less than 4 times per hour. The engineer station 7 performs operations and analyzes on the collected electricity consumption information, and outputs hourly, daily, monthly, and annual building sub-item energy information (each meter information), building actual energy consumption information, building actual energy consumption intensity information, building actual carbon emission information, and building actual carbon emission intensity information.
[0024] Among them, some information is calculated through the following formulas:
[0025] Building actual energy consumption = municipal electricity consumption + distributed energy system power generation - new energy vehicle charging pile electricity consumption. (Note: The actual electricity consumption sources of the equipment maintaining the normal operation of the building include municipal power supply and distributed energy power supply, and the electricity consumption of new energy vehicles belongs to the traffic system electricity consumption rather than the building itself electricity consumption)
[0026] Building actual energy consumption intensity = building actual energy consumption / building area.
[0027] Building actual carbon emission = (municipal electricity - new energy vehicle charging electricity) × electricity carbon emission factor. (Note: The carbon emission of renewable energy power generation is 0)
[0028] Building actual carbon emission intensity = building actual carbon emission / building area.
[0029] In addition, the device further includes a cloud platform 8. The cloud platform 8 is connected to the switch 7 through wireless communication methods, and is used to collect the electricity consumption of the first smart meter 1, the second smart meter 2, the third smart meter 3, the fourth smart meter 4, and the fifth smart meter 5 to analyze the building energy consumption intensity and carbon emission intensity of the new building energy system. That is to say, the above building energy consumption intensity and carbon emission intensity and other information can be calculated through the cloud platform 8 instead of the engineer station 7.
[0030] The above is a specific description of the preferred embodiment of the present utility model, but the present utility model creation is not limited to the described embodiment. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
