摘要：
Simulation in time domain of the frequency and voltage dynamic and the under frequency load shedding(UFLS) scheme on a real isolated power system is carried out in this paper. It researches the design of UFLS, analyzes traditional schemes and two new adaptive schemes, models the system and these schemes using the PSS/E software. The frequency and voltage dynamic, and these UFLS schemes are simulated and the factors that affect them are analyzed. The result indicates that the ability to maintain the frequency and voltage at a standard level is weaker after the system becomes an isolated system, and it has significance for the secure and steady operation to design a perfect UFLS scheme when considering the influence of voltage.
