燃气轮机是广泛应用于航空、船舶、发电等领域的高效清洁动力装置,性能评估是燃气轮机智能运维的重要内容,但长期依赖于燃气轮机设备供应商和国外商业软件,有待国产自主化。提出了一种基于气路参数的燃气轮机性能评估方法,有效计算出燃气轮机的压气机、透平等熵效率、整机热效率等关键参数；利用不同类型燃气轮机的实际试车数据进行测试和分析,将计算得到的性能参数与设备基准数据进行了对比和分析,结果表明二者具有很高的一致性。基于气路参数的燃气轮机性能评估方法简单、有效、可靠,适用于不同类型燃气轮机,对燃气轮机在线监测和故障诊断有很大帮助,为燃气轮机性能评估提供了新思路,为燃气轮机的设计、运行、维护和管理提供了参考。

 The gas turbine is a highly efficient and clean power device widely used in aviation, marine, and power generation. Performance evaluation is a crucial aspect of intelligent operation and maintenance of gas turbines. However, it has long relied on equipment suppliers and foreign commercial software, highlighting the need for domestic and independent solutions. This paper proposes a performance evaluation method for gas turbines based on gas path parameters, which effectively calculates key parameters such as the isentropic efficiency of compressors and turbines, as well as the overall thermal efficiency. The proposed method is tested and analyzed using actual test data from different types of gas turbines, and the calculated performance parameters are compared with reference benchmark data. The results show a high degree of consistency between the proposed method and the benchmark data. The performance evaluation of gas turbines based on gas path parameters is simple, effective, and reliable, and applicable to various types of gas turbines. It offers significant support for online monitoring and fault diagnosis, provides a new approach to performance evaluation, and serves as a valuable reference for the design, operation, maintenance, and management of gas turbines.
