【Abstract】 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. The analysis, decomposition and the proposed various expressions would be very helpful to deeply depict the various characteristics of components of power systems, and could facilitate the use of component structural model. Finally, the general procedure of constructing component structural model is summarized, and the structural models of some typical components of power systems, such as synchronous generator set, HVDC system, TCSC and UPFC, are given, which demonstrates the generality of the component structural model.更多还原
