Research on the Primary Frequency Regulation of China Southern Power Grid

The primary frequency regulation in China Southern Power Grid (CSG) is introduced: the operating capacity, technology parameters etc, and its favorable effect is also shown through the analysis of the increase of frequency qualified rate in recent three years and the contrast of frequency change during two generator tripping. At the same time, the existing problems and the countermeasures for management, control strategy, and analysis methods are proposed to improve the primary frequency regulation level.
