Maximum Hybrid Entropy Assessment of Equipment Failure Probability Caused by Voltage Sags

Abstract:

In order to depict the complex uncertainty involved in evaluation of equipment sensitivity to voltage sags, the voltage tolerance level of sensitive equipment is characterized by interval data, a evaluation model is proposed to derive interval probabilities of equipment operation status. Hybrid entropy is used to measure the uncertainty of randomness and fuzziness. Then, the interval result is transformed into point-valued probability based on maximum hybrid entropy model. By the help of personal computers, the proposed model is finally verified in a test distribution system.
