Abstract
Automatic generation control (AGC) is an essential requirement of modern power system automatic control. At present, slow response to AGC load demand is a serious problem existing in thermal power units taking part in AGC, which makes the control performance of power system AGC poor. The unit one and unit two of Yaomeng Power Co. Ltd., are all once-through boiler, its boiler-turbine coordinated control system (CCS) is based on incremental state observer combined with conventional PID control, and the connection logic of CCS with AGC adopted the scheme shown in this paper. Through adopting the connection logic of CCS with AGC, the pre-add coal function can be realized in AGC mode, which assured the rapid response to AGC load demand of the power unit, and this viewpoint has been fully proved by the trend curves of AGC adjusting test of the two units.
