供热机组负荷指令多尺度前馈协调控制方案
Multi-scale feedforward coordinated control scheme for load command of heat supply units
摘要
Abstract
Using energy storage in heat supply net can change the proportion of heat supply units'power and heat load thus to enhance the units'rapid load regulation ability.Changing the power load by fuel amount costs long time,while by energy storage in heat supply net is fast.On this basis,a rate multi-scale decom-position method was chosen,which could decompose load command into slow-varying signal and fast-var-ying signal.Adding these two signals on fuel and heat supply regulating valve command separately,a multi-scale feedforward coordinated control method with closed-loop heat supply control was obtained.The simu-lation results show that,when the units'load changes fast,the multi-scale feedforward control method can reduce the fuel amount fluctuation effectively.Within permitted heat supply extraction pressure scale,a smaller decomposition rate is benefit to the units'stability.关键词
