摘要
根据发电厂的运行特点,以发电成本最低为目标,建立了厂内单元机组间负荷优化分配的数学模型,并通过动态规划方法求出模型的最优解,获得各台机组的经济负荷分配方案。在此基础上,以单元机组中各类主要运行设备的状态综合评价结果为依据,对经济负荷分配方案进行调整,实现了具有经济性和安全性的负荷优化分配。
Based on operation features of thermal power plants, and taking optimal cost of power generation as the target, a mathematic model for optimal load despatch among block units in the power plant has been established, and optimal solution of the model being found through dynamic planning method, obtaining economic load despatch scheme of each block unit. On this basis, and adjusting method for economic load dispatch schemes based on comprehensive evaluation results for status of each main operating equipment in the block unit has been put forward, realizing load despatch under consideration of economic behavior and safety at the same time.
