针对国电大武口热电有限公司1号机组送风机辅机故障快速减负荷（Run Back，RB）动作后造成的主蒸汽压力超标现象，通过对RB控制策略进行分析，采用逻辑修改、比例积分微分（Proportion Integration Derivative，PID）和参数优化的方法，使RB发生后主蒸汽压力能稳定在合适的范围内。结果表明：快速减煤和加强汽机主控的调节作用，解决了RB工况中主蒸汽超压缺陷，提高机组效率及运行安全可靠性。
針對國電大武口熱電有限公司1號機組送風機輔機故障快速減負荷（Run Back，RB）動作後造成的主蒸汽壓力超標現象，通過對RB控製策略進行分析，採用邏輯脩改、比例積分微分（Proportion Integration Derivative，PID）和參數優化的方法，使RB髮生後主蒸汽壓力能穩定在閤適的範圍內。結果錶明：快速減煤和加彊汽機主控的調節作用，解決瞭RB工況中主蒸汽超壓缺陷，提高機組效率及運行安全可靠性。

Aiming at the phenomena of main steam overpressure caused by blower RB action of unit 1 in State Group Power Dawukou Thermal Power Co.,Ltd.,adopts the method of logic revision and the optimization of proportion Integration derivative parameters,makes main steam keep stability in a suitable range after RB happened. The result shows that rapid reduction of coal and to strengthen the regulation of turbine master control effect,solved the main steam overpressure defects in RB condition,raises the efficiency and safety and reliability of operation.
