摘要/Abstract

摘要： 由于台山电厂1 000 MW机组原设计并不具备FCB功能,FCB功能是在机组投产后充分利用原有设备设计余量基础上进行局部设备改造后实现的。首先对机组系统配置进行分析,确认该机组初步具备实施FCB的条件,通过各分系统性能试验进一步验证主辅设备性能及系统设计满足实现FCB功能的要求,确定实现FCB功能的方向和策略,利用机组停机机会进行了硬件改造和逻辑完善,最终圆满完成了100%负荷下机组FCB功能试验。结果表明：该机组具备在电网出现重大异常情况下实现自带厂用电运行并可迅速恢复向电网送电的能力。

Abstract: The 1 000-MW unit in Taishan Power Plant did not possess the fast cut back(FCB) function in the original design. The existing FCB function is achieved through the local retrofit based on the margin of the original design. Firstly, the configuration of the unit is analyzed to determine whether the unit is capable of implementing the FCB function. Secondly, the orientation and strategy to realize the FCB function are fixed through the performance test to further verify that the performance and design of the main and auxiliary equipments can satisfy the requirements of the FCB function. Finally, the modification of the equipments and the improvement of the control logics are conducted during unit shutdown to realize the FCB function under 100% load condition. The FCB test results show that the unit has the capability to run with the auxiliary power load and can be restored to power delivery quickly in case of major abnormalities of power grids.

Key words: 1 000 MW, ultra-supercritical, fast cut back (FCB), DCS, retrofit, thermal power plant
