СПОСОБ И СИСТЕМА ДЛЯ ОБНАРУЖЕНИЯ ПРИЗНАКОВ ЗАМЕДЛЕНИЯ И ПОМПАЖА КОМПРЕССОРА

摘要

A method and system for detecting precursors to compressor stall and surge in which at least one compressor parameter is monitored (30,32) to obtain raw data representative of said at least one compressor parameter. The raw data is pre-processed using a frequency demodulator (36) to produce pre-processed data, and the pre-processed raw data is post-processed using a Kalman filter (40) to obtain stall precursors (42).
