摘要:
为获取低温轴流压缩机真实工质条件下的性能参数,建立基于真实工质的喘振检测与控制方法,计算给出了真实工质在全包线范围内的热力和热值,建立了基于真实工质的归一化折合模型,提出了防喘振簇线和性能参数裕度设置方法,建立了基于主、被动判定的喘振检测以及精细化降速、安全裕度自动修正等喘振控制方法。结果表明:真实工质与完全气体相比,热力和热值的最大偏差分别为6.94%和7.54%,折合质量流量和折合转速的最大偏差为5.41%和1.69%,必须考虑真实气体效应的影响;基于运行工况点真实运动轨迹设置的防喘振簇线可实现喘振的准确检测和裕度计算,控制策略满足安全运行所需。
Abstract:Surge detection and anti-surge control of cryogenic axial compressor based on real gas effects were studied. The thermodynamics and caloric of real working fluids with full envelope of cryogenic axial compressor were obtained by calculation, a normalized and corrected model based on real working fluids was developed. Methods of anti-surge cluster lines and performance parameters margin setting were proposed, both methods of surge detection based on initiative and passive determination and anti-surge control of meticulous deceleration and automatic revision of safety margin were developed. The results showed that: compared with ideal gas, the maximum deviations of thermodynamics and caloric of real working fluids were 6.94% and 7.54%, the maximum deviations of corrected mass flow and corrected speed were 5.41% and 1.69%, the influence of real gas effects must be considered obviously. The anti-surge cluster lines based on real motion trajectory of operation points were deemed as sufficient and necessary conditions of surge detection and margin calculation, and the strategies of anti-surge control could meet the requirements of safe operation.
