In view of the correction calculation method for the power of extraction condensing steam turbine without back pressure change at present, a simplified correction calculation method for the influence of back pressure on the power of extraction condensing steam turbine is proposed. This method can accurately calculate the influence of back pressure change on the power of extraction condensing steam turbine, so as to provide guidance for the economic operation of extraction condensing steam turbine.
