Discussion on the Approaches to Improve the Automatic Generation Control Technology Index

In this paper,the basic function of unit coordinated control system is analyzed and validated by experiment,and the primary causes affecting the rate of response to power grid control instruction are analysed as well.The approaches to optimize the control strategy of coordinated control system in power plant are proposed,based on which several approaches to optimize the automatic generation control technology index are put forward in accordance with various interference factors.The control strategy about the closed-loop of coordinated unit and grid is put forward.All the coordinated control system optimized through the approach could meet the demand of the grid dispatching index.
