One or method of operating the compressor when there is a failure in the plurality of measurement signals

摘要

a plurality of measurement data (P _s , P _d , T _s , T _d , h _s , h _{a step (105) to obtain a d} ), based on the non-dimensional analysis of the compressor, the molecular weight of the compressed gas (M _w ) by calculating, measured data (P _s , P _d , T _s , T _d , h _s , h _d step to confirm the Sogo of ) and (120), the measurement data (P _s , P _d , T _s , T _d , h _s , h _d ) of when there is a failure in the first measurement value, and the most recent valid value of the molecular weight (M _w ), the measurement data (P _s , P and _d , T _s , T _d , h _s , h _d ) enabled and Na measurements, the step of replacing an estimate of the first measured value on the basis of a dimensionless analysis compressor (130), the estimated value and the measured data (P _s , P _d , T _s , T _d , h _s , h _d ) based on the valid measurement of the method (100 of operating a compressor comprising the steps of obtaining anti-surge map (300, 400) on the estimation of the operating point (302, 402) and (1)).BACKGROUND 1
