Simulation Study on Improvement of Steam Generator Level Control System of Ling’ao Nuclear Power Station

National Key Laboratory of Reactor System Design Technology, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 利用核电厂瞬态分析和控制系统优化设计程序CATIA2,依据各典型瞬态试验验收的不同准则,通过核电厂典型瞬态下的数值仿真试验,为岭澳核电站解决主给水流量系统管路及调节阀振动问题拟采用的蒸汽发生器给水控制系统改进方案进行了仿真验证。结果表明:该改进方案可行,并且对反应堆控制系统所带来的影响是可接受的。
