The algorithm of the probability of distribution network taking into account voltage sags is analyzed in this article. The definition and reason of voltage sags are introduced at first. The main work of this article is as follows: Dissipated network is used in the power flow calculation. The relations between voltages and distances under all kinds of faults are calculated.The standard of halt of the sensitive loads is proposed and we can use this method to get the probability curves of the amplitudes and durations of the voltage sags of the different users . The results of the calculation used Bayes formula is offered at last. The model used in this article is the fifth bus of RTS—6 in IEEE. The probability results taking into account voltage sags and its exposed areas is calculated. At last the results are analyzed and some methods of raising probability of the distribution network are put forward.Ni Wei ( Electric Power System and Automation )Directed by prof. Yang Jing Yan...
