Résumé

HVAC compressor units are major energy consumers in both residential and commercial buildings today. Faulty and energy wasting operation of these units often goes unnoticed due to the corrective action of feedback control. Power system monitoring is an exciting approach for creating inexpensive, highly capable methods to monitor compressor unit performance. In this paper we develop a method to estimate the instantaneous angular speed (IAS) of the shaft of a reciprocating compressor from the drive motor’s electric signals. Solving the dynamic model of the induction motor overcomes the difficulties that other speed estimation algorithms encounter when the mechanical dynamics are on the same time scale as the electrical dynamics. This procedure obtains useful diagnostic information internal to the compressor without the difficulty of mechanical sensor installation.
