Abstract A system equation for a power system with a static synchronous compensator (STATCOM) is proposed. As an example, a single machine infinite-bus (SMIB) system is studied using a salient-pole generator (X′d ≠ Xq ) model. A differential geometric linearization method is adopted to achieve the coordinated control of generator excitation and the STATCOM. The model of nonlinear system with constraints algebraic equations composed by salient pole generator and STATCOM is established which overcomes the previous strong constraints conditions that the output voltage vector of STATCOM must be set in the d-axis, thus the STATCOM model and control method presented are designed primarily to meet the practical engineering applications. This design method further generalizes the application scope of differential geometry linearization theory and controller. The simulation results demonstrate that the model and the control scheme proposed here are reasonable and effective.
