  • Patent number: 10203312
    Abstract: The present disclosure provides a system for measuring carbon emissions in a power system. The system includes: generation carbon meters, distributed respectively in generators in the power system; network carbon meters, distributed respectively in nodes in the power system; consumption carbon meters, distributed respectively in consumers in the power system; and a center server, in which each carbon meter is configured to collect data for measuring the carbon emissions. The center server is configured to acquire the collected data and to measure the carbon emissions according to the acquired data, and to send measuring results to the corresponding carbon meter. Then each carbon meter is further configured to display according to the measuring results. The carbon emission may be measured in real time.
