汽轮发电机组一次调频技术分析
|
摘要
随着越来越多的超临界和超(超)临界机组并入电网,我国电网的容量正在增加,电网的稳定运行变得越来越重要,一次调频是保证机组稳定运行的有效手段,可以解决因为负荷变化而带来的电网频率振动问题。阐述了一次调频的概念及其关键技术,分析了国内外一次调频技术的发展现状,探讨了一次调频技术的发展趋势。
With more and more supercritical and supercritical units integrated into the power grid, the capacity of China′s power grid is increasing, and the stable operation of the power grid is becoming more and more important. Primary frequency modulation is an effective means to ensure the stable operation of the unit. It can solve the frequency vibration problem of the power grid caused by load change. The concept and key technologies of primary frequency modulation are described, the development status of primary frequency modulation technology at home and abroad is analyzed, and the development trend of primary frequency modulation technology is discussed.
