摘要

Rapid and smooth reactive power compensation is crucial to maintain safe and reliable operation of power systems. This paper presents an adaptive and fault-tolerant control (FTC) approach for reactive power compensation via a three-level cascaded STATCOM (static synchronous compensator). Two sets of FTC algorithms are derived to concurrently accommodate element/actuation faults, modeling uncertainties, system nonlinearities, as well as external disturbances. The resultant control scheme is fault-tolerant and adaptive, yet structurally simple and computationally inexpensive in that little information on system dynamics/parameters is needed for control setup and implementation and there is no need for complicated and costly process for fault-detection and identification. Such user-friendly features are deemed favorable in practical applications.
