Comprehensive Diagnostic Evaluation Method for Power Receiving Substation Facilities and Various Live-Line State Diagnostic Technologies

摘要

To evaluate for the state of deterioration in substation facilities, there is a useful method which uses the evaluation points. For the maintenance field, we applied a diagnostic evaluation method based on the risk level. This method is devised so that the influence degree for each facility of the diagnostic object is taken into consideration. By this diagnostic approach, the social or economic influence degree for each substation is added to the evaluation points defined by conventional deterioration diagnosis so that evaluation can be accomplished based on more realistic risk level. In addition, we calculated costs for repairing the critical items revealed by deterioration diagnosis and renovation services. We also produced the resultant evaluation points assumed to carry out such repair services as an output of the result of secondary diagnosis. We devised a comprehensive diagnostic evaluation method for substation facilities by clarifying the cost performance.
