Study on Reliability Evaluation Method of Components without Enough Fault Data

Abstract:

The reliability assessment of power system components is the key to power system safe and reliable operation. According to the record of actual operation of power system components characteristics, a practical method of reliability evaluation for fault date which is missing components is introduced in this paper. The method is based on Weibull distribution model. It is also a calculation and solving methods of reliability evaluation fault system of missing data components. The system mainly includes sample selection of data, parameter calculation, model checking and failure rate curve drawing. So the transformer as an example, verify the effectiveness of this method. In addition the paper analyses the influencing factors in the transformer reliability, such as voltage grade, manufacturer and product types. In a word, this model provides a systematic and effective method for the practical application of the reliability evaluation of the electrical components.
