Abstract
In this paper
the existing problems of AGC in a hydropower company are analyzed
and the method of AGC optimization is proposed. The optimization objective is achieved by increasing the power regulation mode of the governor
optimizing the PID parameters and the relationship between the AGC and primary frequency modulation
the reasonable division of the vibration region. The results of the actual AGC( auto generation control) load test show that the optimized AGC performance has been improved obviously
which can meet the requirements of the"two rules".
