Embodiment Construction

[0016] The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are given in order to provide a thorough understanding of claimed subject matter. It is evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are shown in block diagram form in order to facilitate description of the claimed subject matter.

[0017] An electrical grid may consist of thousands if not millions of electrical components (eg, also referred to herein as power system devices). Failure of at least some of these electrical components may degrade the performance of the power system. Furthermore, due to, among other things, the cost and / or size of some electrical components, there may be little redundancy at some junction points in the power...

Abstract

Among other things, one or more techniques and / or systems are provided for assessing power system equipment of a power system. Historical sensor data and / or historical field test data collected from the power system equipment may be utilized to develop a health profile of the power system equipment. The health profile is indicative of a predicted health (e.g., or probability of failure) of the power system equipment. In one embodiment, the health profile further comprises a health index score which evaluates that health of the power system equipment in terms of the importance of the power system equipment to the power system. Using the health profiles developed for a plurality of power system equipment, a maintenance strategy for at least a portion of the power system may be developed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 727,875, filed November 19, 2012, entitled "ASSESSMENT OF POWER SYSTEM EQUIPMENT FOR EQUIPMENT MAINTENANCE AND / OR RISK MITIGATION." technical field [0003] The present application relates to the field of power systems, and more particularly to systems and / or techniques for determining the condition or health of various electrical components within a power system to provide maintenance recommendations and / or mitigate failure risks. Background technique [0004] A power system includes a network of electrical components or power system devices configured to supply, transmit and / or use electrical power. For example, an electrical grid (also referred to as a distribution grid) includes generators, transmission systems, and / or distribution systems. A generator or power station is configured to generate electricity from combustible fuels (eg, c...
