Hollysys, as the PC general contractor, participated in the construction of the first smart water project in the domestic nuclear power industry (1) - Qin's No. 2 Plant Chengjing Water Intake Smart Operation and Transformation Project, which was recently completed and put into operation. The project was independently implemented by Hollysys, and the independent, controllable, safe and reliable, and deeply localized control system developed by Hollysys by the nuclear high-tech project was applied for the first time in Qinshan Nuclear Power.
Hardcore control for superior performance
The control system used in this project is a member of Hollysys' new generation of high-end controller LKC series PLC. The system is equipped with a high-performance processor platform - Loongson dual-core high-frequency processor. Provide sufficient computing power for the efficient operation of real-time control tasks; The system is also equipped with a fully redundant architecture, which supports all-round redundancy such as dual rack backplanes, CPU, power supply, I/O, and network, which fully ensures the high availability of the system. LKC series PLC has passed strict product and system tests, and has obtained CE, UL and other international certifications.
Independent and controllable, safe and reliable
Hollysys has mastered all the key technologies of PLC design and development, including key chips and components, embedded real-time operating systems, real-time control engines, real-time industrial networks, programming and configuration software, etc., and all related components and technologies are independently developed and controllable. In addition, Hollysys PLC has realized the localization of cryptographic chips and cryptographic algorithms, and all safe and credible basic technologies, including trusted chips and trusted strategies, have also been independently controlled. Hollysys LKC series PLC adopts a dual-system trusted computing structure, supports the expansion of national cryptography security chips and the integration of SM2/3/4 national cryptography algorithms, and builds a PLC endogenous security active protection system based on trusted 3.0 technology. Strengthen the foundation of information security.
Typical cases of independent implementation
This project is the first nuclear power smart water project in China (1). Based on technologies such as the Internet of Things, cloud computing, and 5G, Hollysys provides plant networks for key businesses such as safety management, production and operation, water quality testing, and equipment management of the water system of nuclear power plants. The integrated system platform realizes the application integration of process system, control system and management centralized control platform, and completes the implementation of all projects such as on-site equipment installation, system commissioning, and control room human factors engineering.
Hollysys has configured a deep domestic PLC system for the project, which has the application characteristics of dual master control unit redundancy, dual power supply redundancy, dual network port redundancy, etc., and applied 5G technology for the first time to achieve long-distance real-time transmission. - Time data communication and control. That is, on the basis of realizing the control of all process system equipment, lighting system equipment and electrical system equipment at the water intake, the control system also receives the control instructions sent by the centralized control platform through the 5G network. The data analysis function of the system also plays a key role in improving the intelligent level of water affairs in Qinshan.
The breakthrough of Hollysys' domestic PLC in this project marks the success of Hollysys to help the in-depth localization of nuclear power instrumentation and control to a new level! The successful operation of the project also proves that the intelligent water system of the nuclear power plant with Hollysys Shenzhen domestic PLC as the core is fully qualified for the application scenario of nuclear power plant water treatment, and the project results can be promoted and applied in more fields. Renovation projects.
