The invention discloses a power distribution network operation monitoring method based on scalable vector graphics. On a server side, a third-party file meeting a scalable vector graphic standard is inputted into a G++ graphic file interpreter, an output result of the G++ graphic file interpreter and an output result of a data adapter are jointly inputted into a power grid topology model unit, an output result of the power grid topology model unit is inputted into a graphic display control logic unit and then inputted into an SVG (scalable vector graphics) DOM (document object model); on a client side, a browser analyzes and displays the scalable vector graphics released by the SVG DOM to make it convenient for dispatching personnel to monitor operating states of a power distribution network in real time. Compared with the prior art, the power distribution network operation monitoring method based on the scalable vector graphics has the advantages that a brand new Web graphic display way and a data-to-browser push mechanism are provided, the problem of sharing of data and graphics in an automatic power distribution system is solved in a certain range, and actual requirements of power distribution network operation monitoring can be completely met.
