随着国民经济的发展和用电结构的改变，电网峰谷差日益增大，机组调峰幅度严重不足，各大电网都面临着高峰负荷出力不足的问题。随着新装的高参数大容量机组不断投人运行，电网总容量迅速增大，而中、小型机组逐步退役，因此，大型火电机组参与电网调峰势在必行。
本文详细探讨了各种调峰方式，并对它们作了详尽的比较。在比较分析了国内外调峰状况后,并针对存在的问题提出了相应的解决方案。然后在介绍各个调峰特性后以较大的篇幅论述了低负荷调峰运行对电力系统的影响,并同等比较,分析了两班制调峰运行。以汽轮发电机组(600MW)调峰运行的适应性问题为研究对象，对低负荷调峰定压运行和滑压运行的经济性比较，以及对造成锅炉和汽轮机效率降低的原因进行分析并找出相应的解决对策，讨论了机组低负荷调峰运行的经济性问题，寻找出经济性适合的调峰运行方式。

关键词: 调峰；低负荷；两班制；经济性；运行

With the growth of the national economy and the changing structure of electricity, poor growing grid Fengyu, a severe shortage of power plants, the major networks are inadequate and faces peak load contribution after contribution Night low and low-key than difficult. With the new look for the high-capacity units parameters vote were operating continuously, the total grid capacity rapidly increasing, and small and medium sized units gradually decommissioned, and therefore large thermal power units in the grid undertaking is important.
The detailed exploration of plants, and they made a detailed comparison. In undertaking comparative analysis of the situation at home and abroad, and to the problems made the corresponding solution. In introducing the various characteristics of plants and then to the larger space with a low load electricity plants operating system, and the same comparison, the analysis of the plants operating two shifts. To turbogenerator set (600MW) undertaking operational adaptability problems for the study of low-load plants will be pressed further pressure operation and functioning of the economy compared to a boiler and steam turbine efficiency and analysis of the causes and identify corresponding solutions discussed were low load plants functioning economy, to find suitable undertaking economic operation.

Key words: the peak; Low load; Double shift; Efficiency; Movement
