Centrifugal compressors are one of the most commonly used equipments powering long distance natural gas pipeline. In this paper, a similarity conversion method centrifugal based on predictor-corrector was proposed. other words, we to predict key parameter and as correction. Compared with field test data, found error predicted outlet pressure compressor controlled at about 2% temperature fluctuated within 2°C, which could satisfy engineering application requirements.
