After careful and considered review of the content and authorship of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE???s Publication Principles.
This paper contains significant portions of original text and figures from the paper cited below. The original text was copied with insufficient attribution (including appropriate references to the original author(s) and/or paper title) and without permission.
Due to the nature of this violation, reasonable effort should be made to remove all past references to this paper, and future references should be made to the following article:
"An Analytical Approach for Stochastic Assessment of Balanced and Unbalanced Voltage Sags in Large Systems"
by Elisa Espinosa Juarez and Araceli Hernandez
in the IEEE Transactions on Power Delivery, Vol 21, No 3, July 2006, pp. 1493-1500
In this paper, voltage sags produced by balanced and unbalanced short circuits are analyzed by means of stochastic assessment methods, i.e., analytical and fault position method. These methods have been tested and compared through simulations on 5-bus standard test system. All the simulations were carried out using a code developed in MATLAB. Simulation results show that these methods give reliable and accurate information related to voltage sag magnitude. However, the analytical approach is straight forward and different fault distributions along the lines can be effortlessly considered. The main feature of this approach is that contrary to the fault positions method, it does not require a pre-assignation of discrete fault positions along the lines. It has been seen that - high number of fault positions is required to obtain reasonable accuracy in case of fault position method.
