摘要

针对某百万千瓦级压水堆核能热电联产系统

利用APROS软件建立动态仿真模型

探究主蒸汽、高压缸排汽、再热蒸汽抽汽供热对电功率的影响

模拟不同供热工况下系统的动态响应特性。结果表明:高压缸排汽处抽汽对电功率的影响最小且供热等效电最低;电功率的响应速率对再热蒸汽、高压缸排汽的抽汽量阶跃变化较敏感;低供热抽汽量阶跃变化时

因温度死区存在

冷却剂平均温度与参考值产生稳态偏差。

Abstract

For a 1 000 MW class pressurized water reactor (PWR) cogeneration system

a dynamic simulation model was established by using APROS software to investigate the effects of steam extraction from live steam

high-pressure exhaust steam

and reheat steam on electrical power. The dynamic response characteristics under various heating conditions were also simulated. The results show that high-pressure exhaust steam extraction has the least impact on power fluctuations and achieves the best equivalent power efficiency for heat supply. The response rate of electric power is sensitive to step changes in the extraction flow rates from reheat steam and high-pressure exhaust steam. When there is a step change in the extraction flow rate for low-temperature heating

a steady-state deviation in the average coolant temperature may occur due to the presence of a temperature dead zone.
