摘　　要：介绍了某660 MW超超临界汽轮机组实现FCB功能设计对机组FCB触发逻辑、主再热蒸汽系统、旁路系统、除氧器容量等系统或设备的配置要求;对具备FCB功能机组及非FCB机组的初建投资费用,及电网故障对停机、启机运行成本消耗进行了经济性比较。结果表明虽然FCB功能机组初投资费用较大,但能有效减少由于电网故障造成的经济损失,同时可以大大降低电厂运行成本,因此在该机组上配备FCB功能的方案是可行的。This paper has introduced a 660 MW ultra supercritical steam turbine unit to realize FCB function design on the unit FCB trigger logic, main reheat steam system, bypass system, deaerator capacity system or equipment configuration requirements; To have the FCB function unit and non FCB unit initial investment cost, and power grid failure to stop, and unit operation cost consumption on the economical comparison. The results show that although the FCB function unit＇s initial investment cost is larger, but can effectively reduce the power grid failure caused economic losses, at the same time can be greatly reduced the cost of operation in power plants, and so on in the unit equipped with FCB function scheme is feasible.
