【Abstract】 A design idea of general turbo compressor′s high-speed online monitoring and operating performance evaluation system has been presented. Some core work, such as computation of the real gas character, turbo compressor thermodynamic performance computation and evaluative feature analysis under operating condition, and also the interface of general-purpose software system, has been introduced and analyzed. Practical application illustrates that the turbo compressor′s real-time information, such as its condition and operating point, results of performance evaluation, the anti-surge margin, is credible and reliable.更多还原
