摘要
对燃气-蒸汽联合循环机组上100%流量旁路系统的功能及必要性进行了详细论述。分析了100%流量旁路在联合循环机组启动、停机及甩负荷或跳闸的事故工况下所发挥的作用。采用新手段获得的数据提高了旁路的控制性能并在实践中经受了检验。从而得出因100%旁路容量自动化程度更高,故而对设备自身及配套辅助设备的性能要求相应更高的结论。另外从旁路自身性能及配套辅助设备性能等角度分析了100%旁路实际运行中可能存在的风险源,并结合实际验证了对机组运行可能造成的风险,要求从设计阶段加以核算。
The functions and necessity of the 100% capacity bypass system for combined cycle power units are discussed in this paper. The effectiveness of the 100% capacity bypass system in different operation statuses, such as, starting up, shutting down, load shedding and unit tripping, is analyzed. The data acquired with new method improve the bypass control performance .and the effectiveness is verified through tests. Thereby, it is concluded that the automation level of the bypass system can be increased by virtue of 100% bypass capacity, and further, by better performance of the bypass system itself and related auxiliary equipment. Additionally, the potential risks in the 100% bypass system operation are not only analyzed from the bypass system itself and the related auxiliary equipment, but also verified through field operation. The risk analysis helps to create the check list which should be done in the design stage.
