Dynamic simulation of voltage collapses

摘要: The authors show some examples of dynamic simulations voltage phenomena using a new general purpose stability program (EUROSTAG) covering in continuous way the classical fields transient, mid-term and long-term stability, also quasi steady state conditions power system. three ability to study depth all taking part collapses. first example considers case an infinite bus feeding reactive load through purely line. With this simple example, it is possible basics instability. second illustrates operation system on lower V, P curve. A two considered. third shows transient merged with dynamics. >
