The invention discloses a power grid programming, management and controlling method and system based on a mobile GIS. The method comprises the steps of: carrying out access of mobile programming data; establishing a power grid programming GIS system based on mobile equipment; carrying out comprehensive querying or positioning; carrying out power grid programming analysis; carrying out interaction sharing on GIS data on the mobile equipment and PC ends; and managing power grid programming and exploration business. The power grid programming, management and controlling method and system have the advantages that existing GIS platform functions are combined with the mobile terminals, and electric power equipment such as transformer substations and power transmission lines are displayed on a map in a superposed manner; and the interactive calling between the map software and the GIS system is realized, various advanced functions such as latitude and longitude positioning based on the GIS system, electric power equipment querying, lineation and user-defined element adding are realized on the mobile terminal, and technical support is provided for the development of the electric power GIS and power grid programming.
