PARTICIPATION FACTOR IN MODEL VOLTAGE STABILITY ANALYSIS

Abstract

This Paper presents use of bus participation factor in modal voltage analysis. This Method is identifying the weakest bus in a distribution network. In heavily loaded systems, voltage stability limit is usually dominant and voltage instability is usually observed following large disturbance. More attention is required to be paid to keep voltage profile and hold the voltage stability under control. In this paper simple voltage stability analysis is carried out for IEEE 30 Bus System using Bus participation factor modal analysis. The method based on the Eigen value decomposition technique known as modal analysis, had been applied to the voltage stability analysis. In this method not only the critical Eigen values are use for evaluating the voltage stability of the system but also associated eigenvector. Thesis presents a bus participation factor corresponding minimum Eigen value is used to identify the weakest bus and SVCs are used to improve voltage profile.
