摘要
以某350 MW超临界燃煤供热机组为例,分析高供热负荷超临界机组在AGC-PROPR模式下调节性能指标不合格的原因,并对机组进行优化,增加供热负荷与电负荷的转换回路,对汽机主控、锅炉主控以及燃料主控的逻辑进行优化,针对性地对PID参数进行了优化。通过优化,调节速率、调节精度、响应时间指标满足要求。提出的优化策略对同类型的高供热负荷超临界机组在AGC-PROPR模式下的优化具有一定指导意义。
Taking a 350 MW supercritical coal-fired heating unit as an example,the reasons for the unqualified regulation performance index of the supercritical unit with high heating load in the AGC-PROPR mode are analyzed,and the unit is optimized.Increase the conversion circuit of heating load and electric load,improve the logic of steam turbine main control,boiler main control and fuel main control,and optimize the PID parameters.Through optimization,the adjustment rate,adjustment accuracy,and response time indicators meet the requirements.The proposed set of optimization strategies has certain guiding significance for the optimization of the same type of high heating load supercritical unit under the AGC-PROPR mode.
