摘要
燃气轮机性能的好坏决定着燃气轮机的使用效率和运营成本,对燃气轮机的性能进行评价有着重要意义。鉴于当前性能评价中的常权赋值法存在的局限性,本文介绍了变权综合评价理论,构建了基于变权赋值模型的燃气轮机性能评价模型,且给出了实例,同时结合变权赋值特点对结果进行了讨论。由实例应用可以看出,变权模型能够克服燃气轮机性能静态评价以及常权赋值产生的弊端,最大可能地减少了模型缺陷对评价结果的影响。
The quality of the performance of gas turbine determines so many areas such as efficiency of using gas turbine, operating cost and so on, so that it is of great significance to evaluate the gas turbine performance. Given the deficiencies and limitations in the presence of the regulax weight assignment method in the current performance evaluation, a comprehensive evaluation theory of the variable weight is introduced, the gas turbine performance assessment model based on the variable weight assignment model is built, and the example is given, meanwhile, which result is dlseuessed by combining with the characteristics of ,variable weight assignment in the paper. It can be seen from the application example that the variable weight model nan overcome the defects from the static evaluation of gas turbine performance and regular weight assignment, and can reduce the impact of the model flaw on evaluation results as big as possible.
