Abstract: With the continuous transformation of global energy structure,
in order to better adapt to climate change, ensure the safety of energy
use and develop green energy, it is necessary to continuously upgrade
and optimize the existing smart grid. Non-intrusive load monitoring
has broad application and development prospects in power
system. This paper uses non-invasive power information acquisition
technology to store the original voltage information and original
current information, and establishes a complete "power information
acquisition and storage system". The voltage and current sampling
circuit is designed, and the original information is transmitted to the
server through UDP communication protocol. On the server side, the
data package is analyzed, calculated and transformed, and the data
table is established according to the device ID for data storage. In this
paper, some application scenarios of non-invasive load monitoring are
visually displayed, which can push monthly power health status and
energy consumption statistics for users, and push monthly safety alarm
statistics for management side.
Key words: Electric power information acquisition; UDP protocol; Big data storage
