The methodology of risk evaluation for power equipment technical state assessment

摘要

The paper provides the methodology of power network equipment technical state assessment risk evaluation to ensure effective power network operation and optimization of maintenance and repair schedules. The analysis of existing approaches for risk assessment is carried out from the point of mathematical formulation and existing application practice. The case study illustrates the calculation of technical state assessment risks for 110 kV oil-filled power transformer, based on neuro-fuzzy inference approach.
