Abstract: The factors influencing the passing rate of primary frequency regulation of thermal power units are categorized and analyzed from four aspects of signal acquisition, logical control, actuator system and signal transmission. After these factors are detected and tackled in the running units, the passing rate of primary frequency regulation is effectively improved. When meeting the requirements of the power grid, the units will be able to gain more generation opportunities.

Key words: primary frequency regulation, thermal power unit, passing rate
