The invention provides a method for improving testing efficiency and accuracy of an automatic relay protection tester. The method comprises the steps of defining information name according to the relay protection six-unification standard; building a template file of a station level model; importing and analyzing a SCD file from a client of the relay protection tester; matching the information name defined by the template file with the corresponding content of the SCD file; creating unified final model file of the station level model for different types of protection devices from different plants based on the template file. The method is simple and quick, so that the accuracy and efficiency of constructing the model are greatly increased by being compared with the common matching manner, and as a result, the testing efficiency and accuracy of the automatic relay protecting tester can be effectively increased.
