摘要/Abstract

摘要： 以PG9171E型燃气轮机为顶循环的联合循环机组作为研究对象，利用EBSILON软件搭建了燃气-蒸汽联合循环系统变工况模型，通过改变供热抽汽量以及相应边界条件，分析了抽汽量变化对联合循环调峰能力的影响情况。结果表明：在供热抽汽量0~135 t/h内，机组调峰裕度为32.16~213.65 MW。比较了不同抽汽量下联合循环机组最小、最大发电功率，发现随着抽汽量的增加，机组的最小发电功率增大而最大发电功率减小。研究结果可为联合循环机组的经济运行和电网调峰决策提供重要参考。

Abstract: Taking the PG9171E gas turbine as the top cycle unit as the research object, the gas-steam combined cycle system model for varying operation conditions is established by using the EBSILON software. The influence of the extraction rate variation on the peak-shaving capacity of the combined cycle is analyzed by changing the steam extraction and boundary conditions. The results show that the peak regulation margin of the unit is 32.16~213.65 MW when the steam extraction is lower than 135t/h. The minimum and maximum generation power of the combined cycle unit with different extraction capacity are compared in this paper. It is found that the minimum generation power increases and the maximum generation power decreases with the increase of the extraction capacity. The results can provide an important reference for the economic operation of combined cycle units and the decision of power grid peak-shaving.

Key words: combined cycle, varying operation conditions, steam extraction, peak load regulation
