A comprehensive analysis and combing of the contents of standard check has been carried out for the secondary system information model of a smart substation

which meets not only the conformance testing requirements of the IEC 61850 model

but also the conformance testing requirements of standard engineering application modeling specifications of State Grid Corporation of China(SGCC)and the conformance testing between different application device models. In order to increase the flexibility and speed of model automation checking

two new methods for model static checking are proposed

one is based on the extensible data template and rule

the other on the double nested Hash table. In addition

a check method based on comparison with dynamic memory tree is proposed for model dynamic checking. An automatic model testing tool is developed with the above-mentioned methods. This tool has been successfully used to carry out model checking by testing institutions to improve the comprehensive degree and automation level of the model check

thus guaranteeing the implementation of standard model database of SGCC.This work is supported by State Grid Corporation of China(No. DZ71-15-044).
