Abstract: For coal gasification operation optimization problem,a multi-population competitive co-evolutionary cultural differential evolution(MCCDE)algorithm is proposed.In MCCDE,a competitive co-evolutionary strategy based on differential evolution and a fitness value evaluation method are designed.And some ideas from cultural algorithm are also introduced into MCCDE.Meanwhile,an operation optimization model is constructed.MCCDE algorithm is used to solve the problem of operation optimization model.Simulations with a Texaco gasification unit for example testified that optimized operation variables can be found and the effective gas rate can be increased by the optimization model and algorithm.Finally,a coal gasification operation optimization system software is designed and developed,modeling,control and optimization technologies can be used in practical production to gain more economic benefits through the use of the coal gasification operation optimization system software.

摘要： 针对水煤浆气化装置操作优化问题,提出了一种多种群竞争型协同文化差分进化算法(MCCDE),算法中建立了基于差分进化算法的竞争型协同策略及竞争适应度评判方法,并引入了文化算法的部分思想。同时,建立了德士古气化炉操作优化模型,将MCCDE算法用于优化模型的求解。采用某化工厂气化系统实际运行数据进行仿真,经过操作优化计算,能够获得优化的控制参数,并提高气化炉有效气产率。最后,开发了水煤浆气化操作优化系统应用软件,能够实现将建模、控制、优化技术应用于实际生产中,以提高装置的经济效益。
