Energy converter performance determination.

摘要

A system for determining performance parameters of an energy converter (12) through the use of function blocks is disclosed. The enthalpy (hin) and entropy (Sin) of the supply fluid to the converter (12), the enthalpy of ideal (isentropic) expansion ( SIMILAR _h1) of the converter, and the enthalpies (h1, h2, h3) of the fluid being extracted from each stage of the converter are determined and are selectively employed as inputs to a plurality of modules. The modules contain function blocks in a logic arrangement and produce a plurality of output signals representative of the operating performance of the energy converter.
