【 摘 要 】

With a 660MW ultra-supercritical steam turbine unit as the research object, the back pressure correction curves of the unit THA condition and 75%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.
