The invention relates to a self-correcting method of the transformer substation equipment running mode accuracy. The self-correcting method is mainly characterized in that telecommand and telemeteringinformation is adapted and is automatically associated with a spacing unit; the telecommand and telemetering information is effectively self-corrected; the spacing unit analyzes equipment to judge the comprehensive state of the spacing unit. The self-correcting method is reasonable in design and makes the acquired telecommand and telemetering information associated with the corresponding equipment spacing unit, through the association relation among signals, the correctness and the effectiveness of the information are analyzed and judged, by analyzing equipment at all positions of the equipment spacing unit in combination with the state of the single equipment, the running mode of the equipment spacing unit is accurately judged, the problems that an information point table is inaccurate,there is too much uploading information, and the overall state of the equipment unit cannot be comprehensively judged are solved, an original pure manual analysis mode is greatly broke through, and the overall state of all equipment units can be quickly, accurately and visually analyzed automatically.
