摘要：
The coordinated control problem of static synchronous compensator(STATCOM) and generator excitation for multi-machine power systems is discussed in this paper based on nonlinear control with objective holographic feedbacks(NCOHF). Firstly, the model of nonlinear system with algebraic constraint equations composed by the multi-machines and a STATCOM is established. Secondly, the nonlinear decentralized coordinated control with objective holographic feedbacks(NDCOHF) is proposed. For the local measurements are only needed instead of remote information, NDCOHF has a good robust performance. Additionally, NCOHF is extended to solve the control problems of nonlinear differential algebraic system(NDAS), besides of solving problems of nonlinear differential system. Finally, the simulation is made on a three-machine power system to demonstrate the effectiveness of the method proposed in this paper. The result shows that the proposed method can achieve better of the generators' rotor stability and the better regulation of generators' terminal voltage and the STATCOM's terminal voltage without static error under different disturbances. © 2016, Power System Technology Press.
