Embodiment Construction
[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0020] First of all, according to the "six unifications" standard of relay protection, a universal station control layer model, namely a template file, is established. The template file includes three parts: basic information, test items and parameter configuration. The station control layer model is used in the station control layer client program of the tester to realize the setting of the parameter setting and the protection setting of the tested protection device, the setting of the control word and the soft pressure plate switching mode, the protection of the measured voltage / current phas...

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.
Description
