摘　　要：介绍了等微增算法和动态规划算法的数学模型及获取机组煤耗量的不同方法。分别对通过热力系统反平衡变工况法计算得出的机组在不同负荷下的煤耗量进行了动态规划和等微增计算和比较,分析了动态规划得出2种不同分配方案的原因,指出动态规划算法应用于机组负荷优化分配存在着不稳定性,但在一定条件下等微增和动态规划2种算法其实质相同。The mathematical models of equal incremental principle and dynamic programming method, and several ways to obtain the coal consumption data are introduced. Make comparision between equal incremental principle and dynamic programming method on the coal consumption quantity obtanined through counter balance algorithm. Make an analysis of the two different results caused by dynamic programming in the paper, indicates that dynamic programming applied in the economic load distribution may lead to the instability. In the end the paper proposes that the essence of equal incremental principle and dynamic programming are all the same under certain condition.
