[0002] As the nation promotes a shift from dual control of energy consumption to dual control of carbon emissions, energy is the main battleground, and electricity is the primary arena. Based on the power flow across the generation, transformation, transmission, distribution, and consumption stages of the power system, this paper analyzes the entire lifecycle of carbon dioxide emissions in the power chain. On the source side, methods using equivalent standard coal or equivalent standard natural gas are proposed to roughly calculate carbon dioxide emissions from the generation side. However, on the grid and load sides, these methods rely heavily on uniform carbon emission factors and average energy consumption, failing to accurately calculate the carbon dioxide emissions from individual loads, industrial parks, or power lines.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0017] like Figure 1 As shown, the first aspect of the present invention provides a source-grid-load-based carbon emission conversion metering device. This device calculates carbon emissions by establishing a collaborative mechanism with an electricity meter and a master station. The device includes a microprocessor unit and a communication unit. The communication unit includes a first communication unit and a second communication unit. The communication unit primarily enables communication between the carbon emission conversion metering device, the electricity meter, and the master station. It is applicable to various communication protocols and has strong adaptability. The first communication unit includes Ethernet communication, RS-485 communication, CAN bus communication, and Wi-Fi communication. The second communication unit includes Bluetooth communication. The microprocessor unit connects to the master station through the first communication unit to receive carbon emission factors sent by the master station in real time. The microprocessor unit connects to the electricity meter through the second communication unit to collect power parameters in real time. The carbon emission conversion metering device calculates carbon emissions based on the power parameters and the carbon emission factors. Figure 3 As shown, the microprocessor unit is the core unit of the entire conversion metering device block. It participates in the communication and data processing between the conversion metering device and the outside world, receives and stores the carbon emission factors issued by the main station and the carbon platform, calculates the carbon dioxide emissions and displays them visually.

[0018] The electrocarbon conversion metering device also includes an interface unit, an isolation unit, a time synchronization unit, a human-machine interaction unit, a data storage unit, an intelligent sensing unit, a safety protection unit, a watchdog timer, a power management unit, an LED indicator unit, and a warning and alarm unit. These units are integrated... Figure 3 The specific explanation is as follows: The interface unit is bidirectionally connected to the microprocessor unit via the isolation unit. The interface unit includes a USB interface, a Type-C interface, a power interface, an Ethernet interface, and an RS485 interface. The USB interface facilitates the export of internally stored data from the carbon conversion metering device; the Type-C interface allows for connection to an external power bank for power supply; the Ethernet and RS485 interfaces facilitate wired communication between the carbon conversion metering device and the electricity meter and master station. The interface areas of the carbon conversion metering device use silicone sealing rings, providing high sealing and waterproof performance; the communication interface is covered with an electromagnetic shielding layer and uses electromagnetic shielding elements to reduce internal electromagnetic interference, providing significant electrostatic shielding. Furthermore, its anti-static protection level reaches IP55.

[0019] The isolation unit is used not only to isolate the electric and magnetic fields inside the conversion metering device to avoid mutual interference between the electrical and magnetic signals inside the device, but also to prevent mutual coupling and interference between electrical signals of different frequencies in the device, which could cause calculation errors in the microprocessor unit.

[0020] The microprocessor unit communicates with the time synchronization unit, human-machine interaction unit, and data storage unit via a CAN bus. The time synchronization unit is used to synchronize the time of the carbon conversion metering device, the electricity meter, and the master station; it provides the carbon conversion metering device with accurate system time, which facilitates accurate recording of event occurrence time and the generation of time stamps for carbon emission factors and carbon dioxide emissions.
