在核电站建设过程中,DCS控制机柜及人机接口、网络设备等安装完成后,才能进行与DCS相关的电缆敷设、端接,因此DCS设备的安装是电厂调试工作开始的先决条件,PX泵房进水、电气厂房送冷风等所有系统调试项目都需要DCS的监控,通过对电气、仪控信号的参数实现电站运行自动控制,其供货、安装已位于核电站建造的关键路径之上,直接影响电站各调试目标及总工期目标是否能按期实现。
During the construction of the nuclear power station, the DCS control cabinets and man-machine interfaces, network equipment and other installation is completed, in order to carry out the DCS-related cable laying, termination, so DCS equipment installation is the precondition for commissioning of power plant, PX pump room All the system commissioning items such as water supply and cooling air supply in the electric workshop need DCS monitoring. The automatic operation of the power station is realized through the parameters of electrical and instrumentation signals. The supply and installation are located directly above the critical path for the construction of nuclear power plants. Whether the goal of the commissioning of the power station and the total construction period can be achieved on schedule.
