Implication

Systematic review reveals fixed-interval maintenance dominates electric utilities, highlighting the need for probabilistic mathematical modeling to optimize reliability.

Key Points

To review the current state of power system maintenance strategies and assess how quantitative mathematical modeling impacts power system reliability.
Categorized maintenance strategies by component outcome (full replacement vs. limited improvement) and scheduling trigger (fixed intervals vs. as-needed).
Evaluated industry adoption across heuristic, deterministic, and probabilistic mathematical modeling frameworks in electric utilities.
Fixed-interval maintenance remains the most prevalent approach in electric utilities, frequently supplemented by corrective actions.
As-needed approaches like reliability-centered maintenance (RCM) are gaining adoption in North America, while mathematical models remain rarely utilized.
Probabilistic models outperform deterministic models by quantitatively linking deterioration and repair condition, enabling optimization for minimal cost or maximal reliability.
