核电厂循环水系统稳态及瞬态计算工况研究

Stable and Transient Phenomena of Circulating Water System in Nuclear Power Station

核电厂循环水系统承担着向汽轮机凝汽器供应冷却水的功能,对保证机组的正常稳定运行起着重要作用,一旦循环水失去,会导致机组降功率或者停堆,将带来巨大的经济损失。通过分析核电厂循环水系统稳态、瞬态运行可能出现的各种工况,将各种工况逐个输入软件开展模拟计算,输出成果可以为系统控制、设备设计、设备采购、系统运行程序编制等提供依据,为系统和核电机组的可靠、经济运行提供重要保证。

The function of a circulating water system is to supply cooling water to turbine condenser water boxes. The system is very important for normal operation of nuclear power units. Lack of circulating water could lead to reductions in power output or shut-down of nuclear power units, which could cause huge economic loss. The stable and transient phenomena of circulating water system were analyzed and simulated by software. The results could provide guidelines for system control, equipment design and system operation programming, thereby ensuring the reliable operation of nuclear power units.
