摘要： Systems (200) and methods (300, 400) for predicting a surge event in a compressor (120) of a turbomachine (110) are provided. According to one embodiment of the disclosure, a system (200) may include one or more computer processors (220) associated with the turbomachine (110). The one or more computer processors (220) may be operable to receive a plurality of performance parameters of the compressor (120) and analyze the plurality of performance parameters to determine corrected performance values of the performance parameters. Based at least partially on the corrected performance values, a compressor efficiency may be determined. The processor (220) may be further operable to standardize the compressor efficiency for a standard mode of operation, ascertain historical performance data associated with the standard mode of operation, and analyze the compressor efficiency based at least partially on the historical performance data. Based on the analysis of the compressor efficiency, a surge event may be selectively predicted.

摘要： Systems and methods for determining risk to operating a turbomachine are provided. According to one embodiment of the disclosure, a method (400) may include receiving (402) historical risk profile data associated with a fleet of turbomachines by at least one processor (304) from a repository (302). The method (400) can also include receiving (404) ambient conditions of an environment in which a turbomachine is to be operated. Based at least in part on the historical risk profile data and in view of the ambient conditions, at least one risk threshold for at least one known operating profile can be developed (406). The method (400) may continue with determining (408) that the at least one risk threshold for the at least one known operating profile is reached. Based at least in part on a determination that the at least one risk threshold is reached, a mitigating action associated with the turbomachine can be taken (410).
