| Abstract: | By digital simulation and experiments on actual power unit,problems occurring in primary and secondary frequency modulation processes for DEH system are studied.With overspeed control hardware,frequency modulation and power adjustment were completed for the unit under heavy load rejection and island power grid operation conditions.This proves the control method to be effective in putting large power grids return to normal operation as well as solving the "black start-up" problem. |
