Abstract: In order to make the hydropower operation simulation software system（Wemade） running smoothly, Wemade software network topology structure is extracted combing with the theory of software engineering and complex network. Using network topology characteristic parameters, the structural features of software system is analyzed. It concludes that degree and structural holes present power-law correlation, degree and center degree have no obvious correlation in Wemade software network. This shows that Wemade software structure has a higher modularity and lower hierarchy. Through studying three versions of Wemade software network characteristics, it comes out that network center degree and distribution coefficient get bigger, average shortest path gets smaller, the power-law correlation of structural holes and degree enhances gradually in the process of software system evolution. Therefore, when the software system is redesigned, the clustering and coupling are balanced among modules, the design of key modules are grasped.
