A Study on Improvement Plan of AGC Operation

자동발전제어(Automatic Generation Control) 운용 개선방안

Automatic Generation Control(AGC) is a control system whose objectives are to hold system frequency close to a specified nominal value and to maintain each unit's generation at the most economic value. It has been used to control the output of a generator by the control signal of the generator, but it is not appropriate to apply to generators which adopt the distributed control system. In this paper a method for improving the AGC operation is proposed, and the different response of each generator and various types of control systems of generators are considered. The interface among Remote Terminal Detector(RTU) and control systems and the direct delivery of the data between EMS and DCS also are proposed in the paper.
