Research and design of computer AGC control system in hydropower plant

Abstract

In this paper, the principles and algorithms of automatic generation control system (AGC) in hydropower plants are deeply studied and analyzed. Based on different control methods, the system control model is established. Two methods of economic distribution of generator load are analyzed and demonstrated: Proportional distribution according to unit capacity and distribution according to equal consumed energy ratio. On this basis, use modern computer hardware, software and network technology to design AGC system. Finally, the paper puts forward some suggestions to improve the economic distribution accuracy of load between units and reduce the adjustment error under the equivalent control mode.
