摘　　要：热水供热管网采用分阶段改变流量质调节可以减少循环水泵耗电量.采用动态规划方法对分阶段改变流量质调节的阶段划分进行优化,并对几个不同地区的不同供热系统的电耗进行模拟计算,给出我国北方几个主要城市2、3、4个阶段的分阶段点.计算结果表明,同一地区划分相同阶段的分阶段点相同.Changing the flow mass at different stages may decrease the power consumption of water pump in hot water heat supply network. The mass regulation has been optimized by dynamic programming and changing flow mass. The power consumption in different heating systems and different areas has been simulated numerically. The stage points of the second, third, forth stage in the main cities of Northern China are given. The results of calculation show that the stage point of the same stage is identical in the same area.
