technology，with the help of smart Internet of things（IOT）sensing monitoring terminal，a complex low-voltage
platform topology identification method based on cross platform multi-source data fusion was proposed，and the
system platform was built. Aiming at the district under Bayan power supply bureau，the application experiment of the
system platform was carried out. The results show that the proposed method can carry out multi-dimensional cross
analysis on the state and load of power grid equipment，and form a visual and suitable for the overall operation and
maintenance platform，which has good practicability.
Key words: multi-source data fusion；low-voltage platform；distribution automation；topology identification
