摘　　要：介绍自动发电控制(AGC)和单元机组协调控制系统(CCS)。分析性能试验时怎样处理这两个系统。对"炉跟机"的控制进行了分析。具体对性能试验时保持汽轮机阀位全开、保持汽轮机阀位不变、保持高背压工况和高压加热器切除工况的问题进行了分析并提出了解决措施。这些措施在实践中得到了检验,证明是可行的,为电厂运行人员和性能试验工程师在进行性能试验时提供了理论及实践指导。Perform the analysis of Automatic Generation Control and Coordination Control System. Present the a- nalysis of how to treat the two system when conduct the performance test. Analyze the control of boiler follow： In the process of performance test,combined with the current practice,analyze and suggest the specific procedure of how to keep the governing valves widely open, how to keep the governing valves＇position, how to increase the back pressure, how to shut down the High Pressure Heater. These procedures have been verified in the prac- tice. This can guide the turbine performance test for the operators and engineers.
