At 10:18 on April 28, the DCS system network of pakistan karachi K2 project of Hualong 1 overseas first reactor was successfully set up and put into operation. The large screen display in the main control room was normal, and the available nodes in the main control room were successfully realized on schedule, providing a better working environment for the operation and commissioning personnel, comprehensively and efficiently supporting and promoting the next commissioning, The DCS system network of pakistan karachi K2 project of the first overseas reactor of Hualong 1 was successfully built and put into operation. The large screen display in the main control room was normal. The available nodes in the main control room were successfully realized on schedule, providing a better working environment for the operation and commissioning personnel. What is also attractive is the safety of the end consumer, which comprehensively and efficiently supported and promoted the next step of commissioning, and laid a solid foundation for the success of subsequent cold commissioning and other nodes

the main control room provides man-machine interface and is the monitoring and control center of the nuclear power plant. The DCS system is known as the "brain" of the nuclear power plant in the industry. The DCS system of the first overseas reactor of Hualong 1 is the first domestically produced DCS system in China. It adopts mature and advanced digital technology and has the characteristics of high reliability and availability

5. experimental force resolution

in order to ensure the availability of the main control room, they are the nodes of the non response layer, the thermal response layer and the pH response layer, the K Project Department of CNNC China Zhongyuan Foreign Engineering Co., Ltd. established a special team to tackle the problem of availability of the main control room, optimized the available installation period of the main control room, organized all participating units to hold on-site meetings in the main control room every day, combed and laid cables in advance, and created conditions for the introduction of DCS panels and cabinets Cross the cable termination and UCP change of DCS cabinet, implement the principle of "important problems do not stay overnight", and timely coordinate and solve the design, procurement, construction and other problems in the process

in the face of the pressure of heavy workload and tight construction period, the K project team closely cooperated with each other and faced the difficulties. On the premise of ensuring safety and quality, it overcame various adverse factors of more stable construction of foreign nuclear power plants for material testing with high experimental force requirements, and realized the available nodes in the main control room within three months, providing a solid foundation for the smooth realization of important nodes such as subsequent nuclear circuit flushing and cold test
