state-Space Modeling oif a Series Compensated Long Distance Transmission System Through Graph-Theoretic Approach

The paper demonstrates a powerful application of graph-theoretic approach in developing a linearized state-model for a typical hydro- power system effectively and systematically. The linearized d-q state models of basic components of power system such as generator, transformer, transmission line are formulated (conceptually, in isolation) in a synchronousiy rotating frame which permits ease of inter- connection without involving any intermediary of axis transformations. The formulation of model in general, is applicable to multi- machine system and is easily amenable to digital simulation. It is hoped that the system state-model formulation through graph-the- oretic approach would strongly appeal to power system engineers engaged in large-scale comprehensive dynamical system studies.
