An LQR/Pole Placement Controller Design for STATCOM

The static synchronous compensator (STATCOM) is gaining extensive popularity in power system applications. In general, power factor and stability of the utility system can be improved by STATCOM. Specifically, STATCOM can stabilize a given node voltage and compensate for the power factors of the equipment serviced by that node. So STATCOM is a multiple input, multiple output nonlinear system. In this paper, we want to design a controller for STATCOM by using LQR and pole assignment methods. Simulation results show that the proposed STATCOM controller can effectively increase transient stability of the power system even in the presence of a large operation point.
