摘　　要：多轴布置燃机联合循环机组的AGC(自动发电控制)功能开发和试验研究是一项较新的课题。根据联合循环机组的特点,提出了负荷协调控制的方式,并采用新的控制策略,放弃常规的PID算法。经过实践检验,能较好地实现联合循环机组的AGC功能。分析了联合循环机组负荷变化的高低限,指出燃机负荷增减具有不同速率,探讨了机组负荷变化对余热锅炉和汽轮机的影响。Automatic Generation Control （AGC） development and test research on multi-shaft combined cycle units are new topics. Based on the characteristics of the combined cycle unit, a new method for load coordinated control is proposed. The new control strategy was adopted and the conventional PID algorithm was abandoned. Practice shows that the new method can effectively realize the AGC function for the combined cycle unit. The upper and lower thresholds for load variation are analyzed, and it is pointed out that the load increases or decreases with different speed rates. The influence of load variation on the HRSG and the steam turbine is discussed.
