Abstract
This paper proposes a new method to study on the fault frequency of sensitive load due to voltage sags based on the Maximum Entropy Principle .Based on the characteristics of voltage sags , the method ascertaines the probabilty density function of VTC according to the maximum entropy principle under the situation that thetdistribution of sensi -tive load VCT is unknown .Then through counting the characteristic parameters of each voltage sag in the period of monitoring time , the fault frequency of the sensitive load is obtained by the cumulative method of various plots .At last, the method is simulated on the personal computer .Compared with the existing method , the simulation results show that the method is accurate and adaptable without subjective assumption and random distribution of VTC .关键词
