135MW汽轮机组滑压运行经济性探讨

Discussion on Economics of Sliding Pressure Operation of 135MW Steam Turbine Unit

国内电网容量越来越大,汽轮发电机组不断发展。当机组长期处于低负荷运行状态,加上设计当中存在的偏差,会使热经济性变低。通常引起低负荷运行的经济性有运行方式及设计等原因,基于此,一定要合理有效地调整它的运行方式。机组在滑压运行过程中,借助运行手段,发挥其热经济性功能,进而减少能源损耗。

The domestic power grid capacity is getting bigger and bigger,and the steam turbine generator set is developing continuously.When the unit is in a low-load operation for a long time,and the deviation in the design,the thermal economy will be low.The economics that usually cause low-load operation have reasons such as operation mode and design.Based on this,it is necessary to adjust its operation mode reasonably and effectively.During the sliding pressure operation,the unit exerts its thermal economy function by means of operation means,thereby reducing energy consumption.
