李轩,等 ELECTRIC DRIVE 2022 2022e carrier 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.
