| Abstract: | The existing problems in the AGC remote control function of the hydropower station monitoring and control system are analyzed. Each link and its delay time related to the hydropower station monitoring and control system receiving remote AGC commands from the provincial dispatch center are measured. Based on the analysis of the cause of time delay, improvements are proposed for reducing control loops and enhancing data transmission rate so that the AGC command control delay can be reduced and the precision of control can be improved. |
