摘 要：正In this paper, a two-level control structure of Static Synchronous Var Compensator （STATCOM）, which consists of internal and external control system, is described. The control targets of two levels and relations between them are also proposed. The suggested configuration of control systems can benefit the controller design for STATCOM. H∞ control approach, which considers imprecise parameters and external disturbances, is applied to design the internal controller of STATCOM. Then, some improvements and optimizations based on the dynamical analysis of STATCOM has been developed to achieve better dynamical performance and tracking accuracy.
