Abstract:

Abstract:The indexes of performance check of unit No.1 AGC in Sanhe Power Generation Company Limited and the AGC control mode were introduced. The common problems in AGC control of thermal power units were analyzed. The key factors influencing on AGC performance were pointed out. Combining with the unit operation condition, the control loop influencing on AGC performance was optimized. The check requirements of the power grid on AGC availability rate and AGC regulation performance of the unit No.1 were satisfied.

Key words: Keywords:automatic generation control (AGC), optimization of coordinated control, availability rate, regulation speed, regulation precision, response time
