摘　　要：超临界机组汽动给水泵并泵过程在机组并网后进行,并泵时给水流量波动对机组安全运行产生较大影响,因此保证并泵过程中给水流量相对稳定非常重要。以630 MW超临界机组为例,介绍了汽动给水泵自动并泵控制策略的研究与设计方法。针对汽动给水泵再循环控制对给水流量的影响、并泵过程中的转速控制等控制难点,通过设计合理的控制策略得以解决,并通过实际应用验证自动并泵控制的可靠性,降低了运行人员的操作强度,提高了机组自动化水平。The parallel operation process of steam turbine-driven feedwater pumps for supercritical units is conducted after unit grid connection.Fluctuations in feedwater flow during parallel operation of pumps signifi⁃cantly impact unit safety,making it crucial to maintain relatively stable feedwater flow during this process.Taking a 630 MW supercritical unit as an example,this paper presents the research and design methodology for the control strategy for automatic parallel operation of steam turbine-driven feedwater pumps.Addressing control challenges such as the influence of recirculation control of steam turbine-driven feedwater pumps on feedwater flow and speed regulation during parallel operation of pumps,effective solutions were developed through carefully designed control strategy.Practical applications have verified the reliability of control strategy for automatic parallel operation,which reduces operator workload and enhances unit automation levels.
