Systems and methods for predicting failures in power systems equipment

摘要

Certain embodiments herein are directed to systems and methods to predict failures in power systems equipment. In one embodiment, one or more life-span models associated with power systems equipment may be received. Examples of such life-span models may include a left-censoring model, a right-censoring model, and an interval-censoring model. An accuracy of the life-span models may be determined based at least in part on statistical analysis, such as a Weibull distribution analysis. A stability of the life-span models may also be determined, in certain embodiments herein.

主权项

1. A system, comprising:
at least one memory that stores computer-executable instructions; at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to:
receive at least one life-span model comprising a life-span model parameter associated with power systems equipment and store the at least one life-span model in the at least one memory, wherein the at least one life-span model comprises a complete-censored model, a right-censored model, a left-censored model, or an interval-censored model;determine an accuracy of the at least one life-span model based at least in part on a statistical analysis;determine a stability of the at least one life-span model, wherein the determination of the stability comprises comparing a Beta value of the life-span model parameter to one or more actual power systems equipment failure times;generate a failure time for the power systems equipment;determine an outage distribution based at least in part on at least one of the data or the generated failure time; andgenerate an outage time for the power systems equipment.
