摘　　要：斜流压缩机是大规模压缩空气储能系统组合压缩机的重要型式之一,变工况性能预测在斜流压缩机研发体系中至关重要,其不仅能快速地对初始设计参数进行评估,更针对储能系统压缩机变工况运行的特点进行整体最优参数选择,性能预测模型的准确性至关重要。本文以发展中大规模压缩空气储能系统斜流压缩机为研究对象,自编程建立了斜流压缩机一维性能预测程序,通过设计点参数给出程序对损失模型组合的最优选择结果。然后利用流量系数对非设计点损失模型进行修正,设计结果通过CFD进行验证。结果表明该方法能够有效地预测斜流压缩机在不同导叶开度下的变工况性能。The diagonal compressor is one of the important types of combined compressors for large-scale compressed air energy storage system(CAES).The off-design performance prediction is crucial in the research and development of the diagonal compressor.It can not only quickly evaluate the initial design parameters,but also select the overall optimal parameters according to the char-acteristics of the off-design operation of the compressor in CAES.The accuracy of the performance prediction model is essential.In this paper,a one dimensional performance prediction program for the diagonal compressor of the developing large-scale CAES is established by programming,and the optimal selection result of the loss model combination of the program is given through the design point parameters.Then,the off-design loss model is modified by using the flow coefficient,and the results are verified by CFD.The results show that this method can effectively predict the off-design performance of the diagonal compressor under different guide vane openings.
