At present, the XML data was described by semi-structured data model for discovering frequent pattern in the majority of XML-based data mining algorithms, but there are some defects described XML using semi-structured data model, thus affecting the performance of the mining algorithm.

Firstly by decomposing the interface equation and interface variable set and analyzing the internal constraint relation of interface variable set, the paper gives various expressions of component s structural model of large-scale complex power systems.

Secondly, the component structural model is proposed, which consists of dynamic differential equations and interface algebraic equations.
