摘要

针对大型机组频繁变负荷时磨煤机快速响应的自动启停问题

构建了磨煤机启停过程数学模型。针对该模型特性

对标准粒子群算法进行改进

并对磨煤机启停优化过程进行仿真试验

得到经改进粒子群算法优化后的磨煤机启停状态。将仿真计算得到的磨煤机出力电耗与某电厂1 000MW机组磨煤机现场运行数据进行对比

结果显示优化后的磨煤机启停组合方式能满足机组运行对磨煤机出力的要求

磨煤机每天可节电6.8%。

Abstract

To achieve immediate automatic start and stop of the coal mills during ultra-supercritical units' frequent load varying

a mathematical model for automatic start and stop of the coal mills was proposed.Against this model's characteristics

the PSO algorithm was improved

and simulation test on the optimized start and stop of coal mills was conducted to obtain the start and stop state of coal mills optimized by the improved PSO.Combined with field operation data of coal mills in 1 000MW unit of Datang Chaohou Thermal Power plant

the simulated total power consumption and output capacity of the coal mills were compared with the actual operation data.The results showed that the optimized start and stop of the coal mill satisfied the requirement.Moreover

the coal mills can save electricity by 6.8%every day.
