Simulation Researches Of Static Voltage Stability Based On IEEE Typical System

With the rapid development of modern electric power system, the problem of voltage stability stands out increasingly. The subject of voltage stability has become a hot research subject and an urgent question in electric power system. It includes exploring the mechanisms of voltage collapse, constructing a model that reflects real electric power system as possibly as it can and strengthening the researches of power system voltage stability and security.This thesis carries out studies aiming at the impact of load characteristics and on load tap changer on voltage stability. The impact of load characteristics and on load tap changer on static voltage stability is analyzed with the methods based on V-Q and V-P curves, and the phenomenon of voltage stability voltage instability and voltage collapse are studied with steady-state simulation. Finally the thesis presents the essential explanations of both voltagestability and the mechanism of voltage collapse.Xu yonghua (electrical engineering)Directed by prof. Zhang jianhua...
