Abstract

This chapter addresses modeling and control of the STATCOM and associated power system. Component and system level models of the STATCOM appropriate to objectives are covered. Distinction is made between control objectives on the basis of time scale. For some objectives quasi steady state modeling, where electrical network can be modeled with phasors, is sufficient, while for others, the dynamics of electrical network elements have to be considered on an instantaneous basis. The main control requirements and benefits of STATCOMs in transmission and distribution applications for which quasi steady state analysis suffices are presented in brief. Sub-cycle modeling and control is emphasized since quasi steady state applications will be covered in greater detail in other chapters. Dynamic models of the STATCOM and the local distribution system suited for subcycle control are derived. The models include transformation to a particular rotating frame that allows clear definition of voltage and current magnitudes, and active and reactive power on an instantaneous basis. Based on the models, linear and nonlinear control techniques for the control objective of voltage regulation at a load point are covered in detail. Simulation results are included for representative system parameters.
