| Summary: | The static synchronous compensator (STATCOM) is increasingly popular in power system application. 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 equipment serviced by that node. The dynamic performance of STATCOM is critical to these performance and stability function. STATCOM is a multiple input and multiple output system (MIMO), which can be presented by a mathematic model. Recently, full MIMO state feedback by pole assignment has been shown to be an improvement over classical PI control. In this thesis, an optimal linear quadratic regulator (LQR) design is a compared to the pole assignment design for transient dynamic performance of STATCOM. It was found that LQR controllers do not offer significant performance improvement to pole assignment. However, as a design method the determination of state feedback gains is easier using the LQR method === A Thesis submitted to the Department of Mechanical Engineering in partial
