ABSTRACT:
A relative horsepower indicator is used with an electrical model of a reciprocating gas compressor. A voltage representing the cylinder motion is modified and multiplied with a voltage representing the cylinder pressure. The result is calibrated to indicate one hundred percent cylinder horsepower when the model is operated under ideal conditions. The indicator is then used to indicate deviations from this ideal operating mode when the compressor model is used in a complete pumping system model.
