摘要
为确保火力发电机组能可靠地实现FCB功能,对影响机组FCB功能实现的若干技术问题进行探讨。分析结果表明,蒸汽管道系统、凝给水系统、给水泵汽轮机汽源、机组运行方式以及FCB控制逻辑等问题均会影响机组FCB功能实现。结合某区域电网2台350 MW超临界机组的FCB动作情况进行了分析。研究成果对于增强区域电网防范风险能力具有参考借鉴意义。
In order to guarantee the reliable realization of FCB function in thermal power generator unit, Several technical problems which influent the realization of FCB function in generator unit are discussed. Analysis results show that problems including steam pipe system, condensate water supply system, steam source of water pump turbine, operation mode of unit and FCB control logic and so on will all influent the realization of FCB function. FCB actions of two 350 MW supercritical units in a regional power grid are analyzed. Research results have reference significance to the enhancement of risk prevention ability of regional power grid.
