The Application Research of HVDC FACTS to Suppress the Power System Low-Frequency Oscillation

摘要

With the widely application use of UHV (ultra-high-voltage) transmission, increased the system low frequency oscillations, and flexible application of high-voltage direct current transmission (HVDC) and flexible ac transmission system (FACTS) can improve the system damping oscillation inhibition. This paper Based on the research results in recent years, classify& summarize HVDC and FACTS devices the theoretical basis and the main application places, and according to the way of access system of parallel, series and parallel hybrid FACTS devices stable controller design and optimization are summarized and classified.
