摘　　要：超超临界燃煤发电机组快速甩负荷(Fast Cut Back,FCB)技术可以在电网故障时快速将机组与电网解列,实现机组带厂用电孤岛运行,减少机组停机次数,在电网故障排除后可以迅速提升机组负荷,加快电网恢复速度。以神华国华印尼爪哇1050MW燃煤发电工程中的FCB系统为研究对象,系统分析了FCB系统中机组的关键性能参数,根据FCB工况特性,详细论述了FCB动作过程各系统与设备的匹配运行方式,并对FCB系统的主要设备进行了选型优化。印尼爪哇工程FCB系统的设计与优化为我国参与设计、制造、建设同类机组工程奠定重要的理论基础,积累了宝贵的工程实践经验。Fast Cut Back(FCB) for ultra supercritical coal-fired generating units can quickly disconnect the units from the power grid in case of power grid failure, realize the islanding operation of units with auxiliary power, reduce the number of unit downtime, and quickly increase the unit load and speed up the recovery speed of power grid after the grid fault is eliminated. Taking the FCB system of Shenhua Guohua Indonesia Java 1050 MW coal-fired power generation project as the research object, the key performance parameters of the unit in the FCB system are systematically analyzed. According to the characteristics of FCB conditions, the matching operation mode of each system and equipment in the FCB operation process is discussed in detail, and the selection and optimization of the main equipment of the FCB system are carried out. The design and optimization of FCB system of Java project in Indonesia has laid an important theoretical foundation for China to participate in the design, manufacture and construction of similar units, and accumulated valuable engineering practice experience.
