摘要：The micro increase output test is a reliable and effective way to obtain the back pressure correction curve of steam turbines. The test results are not only applicable to daily energy-saving analysis of steam turbines, but also instructive in the optimal operation of circulating water system. With a 660MW ultra-supercritical steam turbine unit as the research object, the back pressure correction curves of the unit THA condition, 75%THA condition and 50%THA condition were obtained by the micro increase output test. During the test, the flow of condensate was kept unchanged to avoid the influence of the changes of the low-pressure regenerative extraction flow on the test results.
