【Abstract】 There are many kinds of data such as the st ate,the frame and the parameter in the power system calculation database.In this paper the power system can be directly presented with the aid of O-O techniqu e and the frame class data,which comes up to the graph standard.The g raph is made into the platform through which the large power calculation databas e can be safeguarded and managed.And the automatic process from the database to a power system graph is realized using a reasonable technique line and the algor ithms.更多还原
