蒸汽发生器蒸汽压力变化下汽轮机限负荷参数定值分析计算

Analysis and calculation on Load Limit of a Steam Turbine at Varying Outlet Pressures of the Steam Generator

综合考虑反应堆超功率限制条件和汽轮机安全可靠运行因素,提出在蒸汽发生器出口蒸汽压力持续下降情况下,汽轮机限负荷参数定值分析计算方法,结合某电厂运行数据,利用Excel软件进行模拟计算,经实际验证结果良好。

By comprehensively considering the overpower restriction and the security of a steam turbine, an analysis and calculation method was proposed for the setting of its load limit in the case of continuous decline of the steam generator outlet pressure. Based on the operation data of a power plant, simulated calculation was conducted, and the results were proved to be accurate.
