徐大堡核电厂汽轮机冷端优化分析

Optimization and Analysis of Turbine Cold Side in Xudapu Nuclear Power Plant

讨论了如何结合徐大堡核电厂址条件、原材料及汽轮机主要冷端设备价格、供排水系统主要构筑物的造价和相关的年运行费、发电收益等多方面因素,通过多方案经济、技术比较,寻求最优的冷却水系统配置,即选择汽轮机低压缸配置方案、凝汽器面积、冷却水泵流量、冷却水管沟等最优的配套组合方案,确定经济合理的汽轮机冷端各设备的设计参数。

After discussing how to find out an optimal disposition of cooling system by considering the site condition of the Xudapu nuclear power plant, price of raw material and steam turbine cold side system equipment, the costs of the main structures of supply and drainage system and its annual operation costs, power generating benefits, etc., this paper presents the optimization of cooling water system configuration throgh analysis in both economical and technical aspects. In particular, the optimization includes the configuration of low pressure cylinder, condenser area, the flow rate of cooling water pump, an optimal size of cooling water pipe and trench, an cost-eftective design of all equipments in steam trubine cold side system.
