OPTIMAL LOAD DISTRIBUTION AMONG UNITS IN THERMAL POWER PLANT
摘要
火电机组负荷优化分配以机组的煤耗成本特性为基础
目的是使发电成本最低
其中不但将煤耗量降为最低
并且使全厂机组负荷的变化满足自动发电控制(AGC)的速率和精度的要求
提高供电品质。此外
在机组变负荷过程中尽可能地降低负荷调节频率
提高机组的稳定性
延长主、辅机设备的寿命。对此
研究以煤耗最低为原则
合理分配全厂机组负荷的方法
实现发电厂机组的安全、稳定和经济运行。
Abstract
Taking characteristics of coal consumption cost of the unit as basis
the optimal load distribution among generating units solves mainly the problem of reducing the power generation cost to a minimum value
the goal of it is not only to reduce the coal consumption to a minimum value
first of all
it is necessary to make the load variation of units in the power plant to satisfy the requirments of speed and accuracy in automatic generation control(AGC)
to enhance the quality of power supply.Secondly
in the process of varying load of unit
the frequency of load regulation should be reduced as far as possible
enhancing the stability of unit
lengthening the sevice-life of equipments for main and axiliary machines.For these
a reasonable method for load distribution among units in the whole power plant
which takes minimum coal consumption as a principle
has been studied
to realize safe
stable
and economic operation of units in the power plant.
