| Abstract: | Aiming at the problems of primary frequency modulation responsed slowly, and larger de?viation between the frequency modulation amplitude and setting value in Shizuishan Power Genera?tion Co., Ltd., analyzes the reasons of problems occurred, puts forward optimization schemes. The anal?ysis result shows that there is stagnant tache in primary frequency modulation of digital electronic hy?draulic control system to influence badly the rate and amplitude value of frequency modulation. Afterthe parameter optimization, the functions of primary frequency modulation basically meet the require?ments of power grid. |
