US 2022/0187817 A1 · Risk Assessment at Power Substations

Abstract

Disclosed herein is a data-driven approach for determining and presenting a more intelligent measure of the probability of failure of a substation. The disclosed approach generally involves (i) deriving respective failure probabilities of the individual assets within the substation by taking into consideration certain operating, environmental, maintenance or other types of data related to the individual assets, (ii) determining the electrical configuration of the substation, (iii) determining a substation failure probability based on the respective failure probabilities of the individual assets within the substation and the electrical configuration of the substation, and then (iv) presenting the probability of substation failure and/or the respective failure probabilities for the individual assets to a user in various ways. A user may use this probability of failure together with knowledge of the impact or consequence of a failure at the substation to make planning decisions for the substation or the electrical system.

Dependent claims

A computing system comprising:

a communication interface;
at least one processor;
a non-transitory computer-readable medium;
and
program instructions stored on the non-transitory computer-readable medium that are executable by the at least one processor such that the computing system is capable of:
deriving a respective failure probability for each of a set of assets operating in a substation;
determining an electrical configuration of the substation;
determining a failure probability of the substation based on (i) the derived respective failure probability of each asset in the set of assets and (ii) the electrical configuration of the substation;
and
presenting a visualization that includes an indication of one or more of (i) the respective failure probability for each asset of the set of assets operating in the substation, (ii) the determined electrical configuration of the substation, or (iii) the determined failure probability of the substation.
