核电站汽轮机限负荷参数定值设置研究分析

Analysis on Setting of Turbo-Generator Load Limit for Nuclear Power Stations

阐述了CPR1000堆型核电站堆-机之间控制逻辑关系,分析堆-机参数匹配可能带来的运行风险。通过采集某核电站在运机组实际运行参数,建立数学模型,并进行拟合计算,确定了合理的汽轮发电机组限负荷参数定值,成功应用于某核电站机组。

An introduction is being presented to the reactor-turbine control logic of a CPRIO00 nuclear power station, together with an analysis on possible operation risks caused by parameter mismatching between the reactor and the steam turbine. By collecting actual operation parameters of a running nuclear power station, building up mathematical model, and performing necessary calculation and fitting, a reasonable load limit is determined for turbo-generator sets, which is already applied in a nuclear power station.
