摘　　要：本文根据磨煤机特性与操作规程,将磨煤机接力区间等效为不可分配区间,并将之作为约束条件引入到负荷优化分配过程中;针对该约束条件引入后,优化过程违反约束条件的解数量增加,引起算法搜索效率下降的问题,设计一类基于可分配区间边界信息的解修补策略,解决了不可行解比例过高的问题。文章最后通过对于某厂4台300MW机组的仿真,说明本文所提出方法的有效性。Mills relay ranges are modeled as prohibited zones in load dispatching system, according to characteristics and operation guide of pulverized coal mills. An infeasible solution repairing method is designed for the introduction of those zones,infeasible solution rate decreases during optimizing procedure. Simulations on a thermal power plant with 4×300MW units are done at the end of this paper, rightness and effectiveness of the proposed method is proved.
