摘要
在对某汽轮机进行扩容改造过程中,以机组的做功能力和整机效率为目标函数,运用模拟退火算法进行了多目标优化设计.优化结果表明,此方法不仅能够提供满足设计要求的解集,而且能够克服传统优化算法极易陷入局部极值的缺点.实施后获得了很好的扩容改造效果.
During the process of rebuilding design of one old steam turbine, the simulated annealing algorithm is applied to achieve the multi-objective functions with due consideration given to the power and efficiency. The optimization results indicate that the algorithm not only can offer the concourse of solutions fulfilling the requirements, but also can overcome the limitation that traditional optimization algorithms are easy to get into the local extreme values. After being actualized, the corking performance is demonstrated.
