摘　　要：针对大型火电机组汽轮机滑压运行的问题,对汽轮机滑压运行的工作原理以及设计计算方法进行了详细的论述及分析,并介绍了一种通过迭代求解滑压压力的计算方法。通过采用此方法,对某600 MW亚临界机组的三阀点滑压运行进行了计算,并得到了相应的运行曲线。To solve the problem of the steam turbine sliding pressure operation in the larger-scale thermal power unit,this paper introduces the working principle and calculation method of the steam turbine sliding pressure operation,and introduces an iteration method for solving the pressure of the sliding pressure operation.By using this method,we successfully calculate the sliding pressure operation with 3 valve open and obtain the operation curve for a 600 MW subcritical steam turbine.

关 键 词：滑压运行 滑压运行曲线 迭代法 设计计算
