The invention discloses a service rule based examining method for a virtual secondary circuit between intelligent station devices. The method comprises the following steps of: defining a basic model, wherein a model class used by engineering template description is defined, and the model class comprises: an intelligent device class, an input virtual terminal class, an output virtual terminal class, an input virtual terminal set class, an output virtual terminal set class, a virtual secondary circuit class, a virtual secondary circuit group class, an interval class or a transformer substation design scheme rule class; applying the model class, wherein various engineering templates are defined in combination with relevant standards, regulations, specifications and typical design specification requirements in the power industry, which comprises defining of a standard intelligent device template, defining of an interval type template and defining of transformer substation design scheme rule template; and auditing an SCD file by using the various engineering templates. According to the method provided by the invention, various file errors can be detected earlier after the transformer substation engineering construction design is completed, thereby ensuring the design auditing efficiency of the intelligent transformer substation.
