Availability Evaluation of Overhead Contact Lines Based on a Stochastic Colored Petri Nets Model
IET Electrical Systems in Transportation, Volume 2025, Issue 1, 2025.Due to their nonbackup characteristics and constant exposure to outdoor conditions, the performance of overhead contact lines (OCLs) will gradually degrade over time and further result in equipment defects or frequent failures. These issues significantly impact system availability and incur substantial repair costs.
