摘要
针对电网采用火电机组在线供电煤耗监测系统进行节能发电调度的方式,分析了监测系统测量不确定度对负荷调度结果的影响。根据各种容量及参数的机组供电煤耗特性和当前在线供电煤耗监测现状,提出了按照高准确度的性能试验结果优化机组运行组合和依据在线供电煤耗监测结果进行机组间负荷分配的策略。
Directing against the energy-saving load dispatch of thermal power plants in the power grid using the on-line net coal consumption monitoring system,the influence of uncertainty in measurement of said monitoring system upon the results of load dispatch has been analysed.Based on the net coal consumption behavior of units with various capacities and parameters,as well as the status quo of net coal consumption monitoring at present,an optimal operation grouping of units according to the performance test results with high accuracy,and a strategy of load distribution among units based on the on-line net coal consumption monitoring result have been put forward.
