摘要：
In order to study the effects of recuperator performance on micro gas turbine overall performance, a modified recuperator simulation model was proposed based on recuperator experiment, the gas turbine performance simulation and control law optimization were conducted. The results indicate that variable speed control improves gas turbine part-load thermal efficiency and remaining turbine outlet temperature at design-point value is an effective control strategy to further enhance gas turbine part-load performance. However, the performance under variable speed control also suffers greater deterioration when recuperator performance degradation occurs. The thermal efficiency under variable speed control decreases 4.38% due to 14.80% recuperator effectiveness degradation caused by its internal leakage and blockage. © 2020, Editorial Department of Journal of Propulsion Technology.
