摘　　要：M701F燃气轮机停机后,由SFC带动机组升速至710r/min左右,维持该转速运行,此操作称为高速盘车。本文系统阐述了高速盘车的作用、高速盘车投入有哪些限制条件、机组停机后高速盘车冷却投入的原则以及SPIN与GT SPIN COOLING的区别和联系等,结合笔者工作实际表明,高速盘车是燃气轮机系统重要组成部分,我厂机组长期运行以来很少执行GT SPIN COOLING,而SPIN执行情况较多,多用于离线水洗,或机组启动前试运。After M701F g as t urbine is s hut down,SFC drives t he unit t o s peed up t o a bout 710r/min t o maintain t he s peed.T his operation is called high s peed barring.T his paper s ystematically describes t he r ole of high-speed barring,the restrictive conditions of high-speed turning input,the principle of high-speed turning cooling after unit shutdown,the difference and connection between spin and GT spin cooling,etc.combined with the author's work practice,it is shown that high-speed barring is an important part of gas turbine system,and GT spin has rarely been implemented in our plant for a long time However,spin is often used for of f line water washing or trial operation before unit start-up.
