Název v původním jazyce

Voltage Collapse Prediction for Power Systems

Popis výsledku v původním jazyce

Voltage collapse problem has been one of the major problems in stability analysis of power system. It is also a main concern in power system operation and planning. This paper introduces an analysis technique to predict the voltage collapse of a power system. This method basically computes the smallest eigenvalue and associated eigenvectors of the reduced Jacobian matrix of the power system based on the steady state system model. The eigenvalues are associated with a mode of voltage and reactive power variation. The potential voltage collapse situation of a stable system can be predicted through the evaluation of the minimum positive eigenvalues. The magnitude of each minimum eigenvalue provides a measure how close the system is to voltage collapse. The analysis is performed for IEEE 14 Bus system using the constant load model. These results are compared with theses result, obtained to PSS/E and ETAP power system software.
