The invention discloses a data display method in a power distribution network automated system. The method includes the steps that an SVG standard vector diagram is converted into a C# object; a CIM file, namely a common information model file, is analyzed and mapped to elements of a lpf vector diagram; the lpf vector diagram obtains a measurement point topological relation from a relation database; a dynamic lpf is embedded into a JSP through an ActiveX control, and a configuration graph is displayed in a WEB page. The data display method solves the real-time display problem of data in a real-time database and data in the relation database in power distribution network automated system environment; on the premise that an existing power distribution network system is not changed, common information model analysis is finished, the SVG vector diagram is converted into a lpf diagram with an owned format, the information is displayed in the lpf diagram, and then javascript and the ActiveX control are embedded into the lpf diagram, so that the data in the real-time database and the data in the relation database are displayed in real time on the JSP.
