【摘要】 随着计算机技术的发展，计算机在核工业领域的应用已不仅局限于科学计算或离线仿真，其在线应用方面将得到更大的发展。压水堆核电厂主冷却剂系统是压水堆核电厂中的主要子系统之一，其控制系统的性能水平直接关系到整个核电站机组的安全、可靠、经济运行程度。将集散控制系统作为主冷却剂控制系统是实现主冷却剂系统过程控制的理想方案，也是今后的发展趋势。 双恒定运行方式是指核动力装置在稳态功率改变时，能保持一回路冷却剂平均温度与二回路蒸汽压力均不变。核动力装置采用双恒定运行方式，可以大大改善装置运行特性，有利于整个核动力装置的设计与控制。 本文完成了一种双恒定运行方式下主冷却剂实验系统的集散控制方案设计，整个控制系统分数据采集、综合控制、指令执行三个模块，实现了主冷却剂系统的闭环控制。 由于不具备对实际主冷却剂系统进行控制操作的条件，在完成控制系统方案设计的基础上，本文设计了一种基于Intel 80c196单片机的实验室模拟系统实现了该方案并进行了实验验证。结果表明控制系统可以完成主冷却剂实验系统的各项控制任务，从而说明主冷却剂实验系统的集散控制方案设计是可行的。更多还原

【Abstract】 With the development of computer technology, its application in nuclear industry will not be restricted in scientific computation or off-line simulation. More attention will be paid to its on-line application in future. Reactor Coolant System(RCP) is one of the key subsystems of Pressurized Water Reactor(PWR) nuclear power plant, and the performance of its control system have a direct impact on the security, reliability and economic performance of the whole power plant. To make the control system of RCP be distributed control system is an ideal scenario for the process control of RCP, which is also the trend of future development.In the double-invariance operation mode, nuclear power plant can retain both the average temperature of Primary System and the pressure of Secondary System when its steady power changes. Therefore it significantly ameliorates the system-running characteristic to be more helpful in designing and general controlling for nuclear power plant.This dissertation finished the scenario of a distributed control system for model RCP which is in the double-invariance operation mode. The control system is made up of three subsystems data-acquisition, general control and command execute, and yet implemented the closed loop control of model RCP.In order to validate the scenario of model RCP distributed control system, this dissertation completed the design of a simulative control system base on 80c 196 microcontroller because of the lack of actual RCP system. The result of experimentation releases that the experimental control system can accomplish the control task of model RCP, which authenticates the feasibility of the scenario of distributed model RCP control system.更多还原
