Cloud-based acoustic monitoring, analysis, and diagnostic for power generation system

A method, comprising:

• measuring, via a near field (NF) microphone array, noises generated from a power generation system and traveling in the near field;
• receiving, via an acoustic monitoring, analysis, and diagnostic system, NF noise signals from the NF microphone array;
• measuring, via a far field (FF) microphone array, noises generated from the power generation system and traveling in the far field;
• receiving, via the acoustic monitoring, analysis, and diagnostic system, FF noise signals from the FF microphone array;
• deriving, via the acoustic monitoring, analysis, and diagnostic system, NF noise measurements and FF noise measurements based on the NF signals and the FF signals;
• synchronizing, via the acoustic monitoring, analysis, and diagnostic system, the NF noise measurements and the FF noise measurements into synchronized NF noise data and synchronized FF noise data;
• monitoring, via the acoustic monitoring, analysis, and diagnostic system, noise performance of the power generation system based on the NF noise measurements and FF noise measurements;
• analyzing, via the acoustic monitoring, analysis, and diagnostic system, the synchronized NF noise data and the synchronized FF noise data to create NF noise signature and FF noise signature;
• diagnosing, via the acoustic monitoring, analysis, and diagnostic system, root causes of the measured noises generated from the power generation system based on the NF noise signature and FF noise signature;
• and
• controlling, via the acoustic monitoring, analysis, and diagnostic system, the near field (NF) microphone array and far field (FF) microphone array to measure the noise continuously to generate continuous recorded acoustic signals that provide continuous monitoring of collected data to recognize a change for early failure detection based on the analysis of historical data over the life time of the monitored power generation system.

Non-transitory, tangible, and computer-readable medium storing instructions that, when executed by one or more processors, are configured to cause the one or more processors to:

• control a near field (NF) microphone array configured to measure noises generated from a power generation system;
• control a far field (FF) microphone array configured to measure noises generated from the power generation system;
• receive NF noise measurements from the NF microphone array;
• receive FF noise measurements from the FF microphone array;
• synchronize the NF noise measurements and FF noise measurements to create synchronized NF noise data and synchronized FF noise data;
• monitor noise performance of the power generation system based on the measured noises from the NF microphone array and FF microphone array;
• analyze the synchronized NF noise data and synchronized FF noise data to create NF noise signature and FF noise signature;
• diagnose root causes of the measured noises generated from the power generation system based on the NF noise signature and FF noise signature;
• and
• control the near field (NF) microphone array and far field (FF) microphone array to measure the noise continuously to generate continuous recorded acoustic signals that enable continuous monitoring of collected data to recognize change(s) for early failure detection based on the analysis of historical data over the life time of the monitored power generation system.
