摘要
对压水堆核电厂瞬态仿真程序CATIA 2程序进行了改进,以满足核电厂数字化仪表控制系统优化设计工作的需要。主要的改进是在CATIA 2程序中,对ΔT保护通道引入了数字化采样模块模型及数字化处理时间步长,以及对ΔT保护通道所用的输入变量引入了采样时间步长,并针对数字化技术提出了一种新的超温ΔT定值方程模型。通过分析比较数值仿真的结果,表明所做的改进是合理和可行的。
In order to meet the requirements of the optimization design work for the digital instrument and control system of the nuclear power plant(NPP), the transient simulation program for PWR, CATIA 2 code, has been improved. The main improvements are that the digital sampling module, the digital processing time steps of the △T protection channels and the sample time of the input parameters for the △T protection channels are introduced in the CATIA 2 code. A new over temperature setpoint equation module according to the digital technology is provided. By analyzing and comparing the numerical simulation results, the improvements are proved to be reasonable and feasible.
