An Iterative Method Applied to Correct the Actual Compressor Performance to the Equivalent Performance under the Specified Reference Conditions

摘要

This paper proposes a correction method, which corrects the actual compressorperformance in real operating conditions to the equivalent performance underspecified reference condition. The purpose is to make fair comparisons betweenactual performance against design performance or reference maps under the sameoperating conditions. Then the abnormal operating conditions or early failureindications can be identified through condition monitoring, which helps toavoid mandatory shutdown and reduces maintenance costs. The corrections arebased on an iterative scheme, which simultaneously correct the main performanceparameters known as the polytropic head, the gas power, and the polytropicefficiency. The excellent performance of the method is demonstrated byperforming the corrections over real industrial measurements.
