Method for controlling a gap minimization of a gas turbine
The invention relates to a method for controlling a gap minimization for an adjustable gap between a rotor and a housing of a gas turbine. This is carried out on the basis of a correlation extracted from simulation data. If the actual value (PI) lies below the lower threshold (PU), the gap minimizat...

| description | The invention relates to a method for controlling a gap minimization for an adjustable gap between a rotor and a housing of a gas turbine. This is carried out on the basis of a correlation extracted from simulation data. If the actual value (PI) lies below the lower threshold (PU), the gap minimization is deactivated, whereas if the actual value lies above the upper threshold (PO), the gap minimization is activated. The gap minimization is activated between the thresholds (PU, PO) if the actual value lies above the threshold (PG) but is deactivated if the actual value (PI) lies below the threshold (PG).
本发明涉及一种用于控制在燃气轮机的转子和壳体之间的可调间隙的间隙最小化的方法。为了在燃气轮机的运行中确保高度精确的间隙调节，持续确定运行参数的实际值(PI)，例如燃气轮机的相对功率(PREL)，并且将相对功率(PREL)与下限阈值(PU)和上限阈值(PO)进行比较，在预定的时间段中确定实际值(PI)的最大值(PMAX)并从中确定极限值(PG)，该极限值(PG)位于下限阈值(PU)和上限阈值(PO)之间。这基于从仿真数据中提取的关联性来进行。如果实际值(PI)低于下限阈值(PU)，则停用间隙最小化，而如果实际值(PI)高于上限阈值(PO)，则激活间隙最小化。在阈值(PU、PO)之间的情况下，如果实际值(PI)高于极限值(PG)，则激活间隙最小化，而如果其低于极限值(PG)，则停用间隙最小化。 |
