Course Objective Stability is the leading actual problem compared to the other problems encountered during generation and transmission of electrical energy. Addition to classical angle stability approach, voltage stability in major transmission systems has a continuously increasing importance. Aim of this course is to redound the required knowledge and skills to be able to make voltage stability analysis and prevention designs.
Course Content Introduction, Projections (schemes) of transmission systems, Load models, Static voltage stability, Examination of the factors that effect voltage stability, Critical values, Dynamic voltage stability, Dynamic load models, Dynamic load flow, Factors that effect the dynamic voltage stability, Voltage stability in “N” busbar(ed) systems, Actual improvements in voltage stability researches
