摘　　要：机组负荷优化分配是一种提高电厂经济性的方法,但目前还没有一种绝对严格的算法来实现这种优化分配。引入模糊理论,建立了电站机组负荷分配模型,并运用爬山算法与基于Matlab的遗传算法相结合求解。该算法不同于常规优化算法,其特点是优化过程简单、容易得到全局最优解、适合大规模的复杂系统求解。通过算例分析,验证了该方法的有效性。Load optimization dispatch of the power unit is one of the methods to enhance economic performance of power plant , but at present, there is no absolutely strict algorithm for the purpose. The load dispatch model is established by introducing fuzzy theory, and the solution is got by combining the genetic algorithm based on Matlab and hill-climbing algorithm. Different from the regular optimization algorithms, it features simple process and to get the global optimal solution easily ; and suitable for large-scaled complicated systems. The effectiveness of the method is verified through calculation example.
