摘要(Abstract)：

大型火电机组励磁系统进行国产化替代，要打破技术壁垒，从信息系统、控制系统和电子器件等多方面实现突破。首先，对现代励磁技术的控制与指令子系统、通信子系统、整流子系统及灭磁子系统等关键技术进行了系统地总结归纳，针对各技术所涉及的研究现状、存在问题及难点进行了分析与概述；其次，叙述了大型超临界670 MW火电机组HN-i6200励磁系统的国产化替代历程，对于火电机组励磁系统运行的特殊要求，开展针对性设计，研制高可靠性的国产直流开关，并通过试验研究攻克火电机组励磁系统的运行策略，成功研制出全国产化HN-i6200型励磁系统。现场测试与系统建模验证了全国产化励磁系统工作性能，为电力工业励磁技术的国产化提供了技术与实践参考。
