| Abstract: | For a 660 MW ultra-supercritical steam turbine unit, the article analyzed that the steam source switching and feed water control modes on feed water pump turbine while doing FCB test. Through optimizing the high（low） pressure control valves and feed water control modes on FCB operation condition, summarized the matching relationship between the high pressure regulation valve＇s opening degree and unit＇s load by the FCB testing. By optimization, the logical could meet the requirements of the FCB operation rules. |
