摘要
针对某电厂9FA机组在停机过程中发生的PPM和SPPM往复切换问题的原因进行了分析。发现导致该问题的原因为当燃机处于PPM到SPPM之间的切换点时,燃机负荷指令为保持状态,TTRF1在切换点附近波动。对相关的参数进行优化解决了该问题。
This paper analyzes the transfer fail of PPM to SPPM during the shutdown process in 9FA gas turbine. The fail is caused by the fluctuations of the TTRF1 due to command of GT load hold during the transferring. The fail has been solved by modifying the control constants.
