考虑故障传播的变压器机会维修模型
Opportunistic Maintenance Optimization Model for Power Transformer Considering Fault Propagation
摘要
Abstract
During power transformer operation,there exist multiple faults due to complex working environment.When a fault happens,accelerating the development of other faults,power system operating efficiency can be adversely impacted.This phenomenon is called fault propagation.To study the impacts of fault propagation on power transformer maintenance strategies,an opportunistic maintenance optimization model was proposed.From a practical point of view,the transformerstate transition process was modeled based on the fault propagation mechanism.Furthermore,to prevent a local fault from leading the system to a catastrophic fault,system maintenance risk and system failure risk were quantified considering scheduled maintenance and opportunistic maintenance.Finally,the sum of system maintenance risk and system failure risk was minimized with maintenance constraints.Numerical studies indicate the feasibility and validity of the proposed model.关键词
