摘　　要：基于Labview软件建立全范围仿真模型,对回热式给水泵汽轮机与主汽轮机协调的运行方式进行了验证及对比分析。结果表明:随着负荷降低,给水泵功率较给水泵汽轮机输出功率降幅更大;背压调节和进汽节流相结合的运行方式不仅能够满足功率要求,而且能够保证机组高效经济运行。A full scope simulation model was established for a regenerative feed pump turbine using Labview software, based on which, verification tests and comparative analysis were conducted on the coordinated operation mode of the regenerative feed pump turbine with the main turbine. Results show that with the reduction of unit load, the decreasing amplitude of the feed pump is higher than that of the feed pump turbine;adopting the operation mode of combined back pressure regulation with inlet steam throttling can not only meet the requirements of power matching, but also ensure the efficient and economic operation of the unit.
