As the major summit modulation and frequency modulation sets in Shandong electric grid, one-time frequency modulation technology's reasonable applications play a crucial role in enhancing Shiheng Electric Power Plant's safety operation and its electricity frequency quality. Therefore, analyzing and researching the power sets' input to the one-time frequency modulation process is the focus of the 4# power set's technical improvements.Abiding by 《One-time Frequency Modulation Technology's Requirements on the Power Sets of Shandong Electric Grid》 and considering the real situation of Shiheng Electric Power Plant, we analyzed and researched the malfunction problem occurring at the 4# power set's one-time frequency modulation process and made some sound optimizations in its key technical process. Dynamic experiments' empirical data indicate the technical improvements have reached the anticipated results and the technical requirements thereof, which are set by Shandong electrical grid.
