| description | The invention discloses a low-pressure cylinder flow passage reconstruction energy-saving effect evaluation method and belongs to the technical field of thermal power generation. The evaluation method in the prior art is small in coverage; and working condition comparison always causes a certain error due to introduction of extra correction, and thus it is hard to realize comprehensive and accurate evaluation. The low-pressure cylinder flow passage reconstruction energy-saving effect evaluation method comprises the following steps: 1) collecting discrete data; 2) carrying out data fitting on the discrete data and obtaining a fitting formula; 3) collecting unit load and low-pressure cylinder exhaust steam pressure data; 4) according to the fitting formula, calculating exhaust steam volume flow, and furthermore, calculating low-pressure cylinder efficiency; and 5) calculating energy saving quantity, carrying out evaluation according to the energy saving quantity, calculating efficiency change amount of a low-pr |
