Analysis and discussion on the key problem of primary frequency regulation for hydroelectric power plants

The paper analyses the key problems about primary frequency regulation such as optimize setting of governors PID,maximum limit load,power reverse adjust,regulation target value,action degree statistic,PFR of Kaplan turbines,the conflict of PFR and AGC,supervisory and examination of PFR,and power regulation of governor.The problem-solving method is put forward which is of great significance in improving the technical criterion and manage of primary frequency regulation.
