Abstract:

The complexity of controlling is analyzed when the phase difference of voltage and current at the access point of STATCOM is in arbitrary angle β which is not in the ideal state of 90 for the coordinated control of detailed model of the salient -pole generators and STATCOM that is one of the core devices of the FACTS. The characteristics of single machine infinite-bus system including STATCOM are analyzed by establishing the nonlinear system model with algebraic constraint equations of one salient-pole generator and STATCOM and the detail control method of the excitation and STATCOM devices is designed by adopting geometric feedback linearization theory combined with classical linear quadratic optimal control. The method of design in this study expands the applied range of geometric linearization theory used in differential-algebraic systems and makes the coordinated control of excitation and STATCOM more feasible for practical engineering applications, which makes up for the insignificancy of the coordinated control research of salient-pole generator excitation and STATCOM.
