650MW核电机组循环水系统最佳运行工况研究

Study on Optimal Operation of 650MW Nuclear Power Plant Circulating Water System

以净功率输出增加最大化为目标,分析、探讨了核电厂循环水系统的优化运行问题。对水量不能连续变化的循环水系统,利用离散优化模型,计算得到我厂3、 4号机组HN650-6.41型号的汽轮机最佳运行工况图。运行人员可以依据该图确定机组在不同循环水温、不同负荷下最经济的循环水泵运行方式。该优化方法简单且可操作性强、节能效果显著,,有很好的推广价值。

With the goal of maximizing the increase of net power output, the problem of optimal operation of the circulating water system of nuclear power plants was analyzed and discussed. For the circulating water system whose water quantity cannot be continuously changed, the discrete operation model is used to calculate the optimal operating conditions of the steam turbines. According to the figure, the operating personnel can determine the most economical operation mode of the circulating water pump under different circulating water temperatures and different loads. The optimization method is simple and operability, and the energy saving effect is remarkable, and has a good promotion value.
