Abstract

Transformer online operation state directly influences the operation state of the whole power system. A transformer online operation state assessment method is proposed in this paper. This method is based on history, real-time, future operation data of transformer, and five evaluation models for device, maintenance, state, operation, and plan are established. Six category twenty-five sub-indexes that impact transformer operation are quantified to estimate the transformer online operation state comprehensively. Then comprehensive index is given by analytic hierarchy process, which ensures the safe and economic operation of transformer.
