Filed maintenance strategy optimizing determination method for converter transformer

The present invention relates to a method for determining the converter transformer site maintenance optimization strategy, converter transformer preventive acquired test data; optimized for rheological site maintenance strategy is determined: t comprises a time maintenance costs for rheological desired program to determine, for Evolution of a risk premium desired time t is determined, determining a certain time t feature amount predicted value f (X, t), the probability P t various types of failures of the converter transformer according to f (X, t) is calculated at a certain time ( Y, t), fault type of risk premium is desirable to determine a time t R (t) is determined highly economical converter transformer maintenance strategy. The present invention may determine the best economic maintenance policy according to the maintenance cost of the converter transformer and the type of fault. In other rheological apply to determine economic policy overhaul to reduce the total cost of the inspection and maintenance of the converter transformer, extending the life cycle of the converter transformer, have a good social and economic benefits.
