摘　　要：针对直流锅炉机组蓄热能力低、快速响应负荷能力差,难以实现一次调频功能的问题,提出采用自适应控制技术,使锅炉、汽轮机、发电机之间相互配合、相互制约、整体协调响应电网频差的变化,解决了超临界直流锅炉机组一次调频能力差的问题。Self-adaptive control technology is put forward to solve problems such as low heat storage capability, poor loadability in response, which makes it difficult to realize primary frequency function. Because of this technology, the boiler, turbine and generator could work together, restrict and coordinate one another to respond to power grid frequency variation. This technology gives a solution to the poor primary frequency modulation of once-through boiler.
