Abstract

An apparatus for determining a top-dead-center (TDC) of a reciprocating compressor (14) includes: a pressure transducer (17) configured to measure pressure fluctuations inside a compressor cylinder (15) and convert the pressure fluctuations into an asynchronous waveform; and at least one computing device (20) operably connected with the pressure transducer (17). The at least one computing device (20) is configured to: extract a data set representing piston angles over a single revolution of a piston (16) within the compressor cylinder (15) from the asynchronous waveform; evaluate a property corresponding to the measured pressure at each piston angle of the revolution data set; determine whether each piston angle of the revolution data set is an invalid piston angle that does not correspond to a TDC position of the piston based at least in part on a comparison of the evaluated property from the respective piston angle to a respective threshold; remove data representing invalid piston angles from the revolution data set to form a refined data set; determine an average piston angle for the single revolution from the refined data set; identify the average piston angle representing a data value of the refined data set as the TDC position of the piston; and adjust the refined data set to identify a TDC position of the piston to be a first data value in the refined data set.
