Global power is very lacking, in response to energy saving, environmental protection, emission reduction, countries around the world are vigorously accelerating the development of nuclear power, China will also vigorously develop clean power, during which nuclear power is the main direction of the country's future power structure adjustment, the scale of investment will greatly exceed the conventional power plant. The national strategy for nuclear power plants has changed from "moderate development" to "active development". In this context, China's nuclear power will have a good opportunity to develop.
According to the "Twelfth Five-Year Plan" power planning idea proposed by the National Power Administration, the "Twelfth Five-Year Plan" power plan should reflect the principle of giving priority to the development of new power and renewable power, during which the development of nuclear power plants should promote inland nuclear power projects and form the eastern and central nuclear power belt.
The development of nuclear power plants has effectively driven the rapid development of the nuclear power equipment industry. At present, the localization rate of China's nuclear power plants is about 50%-60%, and it is planned that the localization rate will be greater than 80% by 2020. According to the calculation of the installed capacity of more than 70 million kilowatts, in the next 10 years, the total investment scale of nuclear power in China will be as high as 1 trillion yuan, and nuclear power equipment will account for about 60% of the investment in nuclear power plants, and the equipment investment will be about 600 billion yuan. If the localization rate of nuclear island, conventional island and auxiliary equipment is 70%, 80% and 90% respectively, then domestic nuclear power equipment manufacturers will share more than 320 billion yuan of shopping malls, and the shopping malls have huge potential.
System description
The digital I&C system of the nuclear power plant controls all the valves, switches, relays, etc. of the entire nuclear power plant from the conventional island to the nuclear island, and the data is displayed in the system, calculated and processed and automatically drives the actuator, which has the characteristics of high reliability, openness, flexibility, coordination, easy protection, and complete control functions. It is the brain, nerve center, operation center and safety barrier of the nuclear power plant, the most critical and core skills of the entire nuclear power plant, the carrier of the core skills of the nuclear power plant, and an important symbol of the modernization of large-scale nuclear power equipment, and one of the four key complete sets of equipment for nuclear power plants.
As a nuclear power unit, such a high-tech and severe equipment with a nuclear reactor as a power, its control system is closely related to the nuclear reaction process, and the functions and functions of the control system such as safety, reliability, accuracy and integrity directly affect the safety and economy of the operation of the entire nuclear power plant.
As the core control system of nuclear power plants, the control system used to be routine equipment, and the power used was relatively low, and the protection cost was very high. With the rapid development of the world's digitalization, informatization, automation and networking, the use of DCS in nuclear power plants is increasing, and domestic nuclear power manufacturers actively respond to the requirements of the country to accelerate the localization process of nuclear power DCS, and EVOC MEC-5007 with high function, low power consumption, big data processing, high reliability, long-distance protection and other characteristics, is fortunate to undertake the control equipment and gateway node unit of the nuclear power non-safety plant-wide digital instrument and control system (NC-DCS), the following is the description of the NC-DCS system
Non-safety plant-wide digital I&C system (NC-DCS)
The system is a fully digital I&C system developed for million-kilowatt pressurized water reactor nuclear power units, which mainly includes the following subsystems:
Reactor protection system
Safety-specific control system
Reactor Power Control System (CCS).
Safety-VDU for the main control room and RSS
Nuclear island control systems other than CCS
Routine Island Manipulation System
KIC system
Large-screen display system POP
Back-up operation panel BUP (including PAMS)
Features of NC-DCS system:
Software component planning, planning standardized software module interface, according to the internal software bus, complete the software function configuration on demand
Strengthen the self-diagnosis plan, and choose the method of combining hardware Watchdog and software mission diagnosis to detect the problem in time when the equipment has serious problems
According to the two-layer network structure of control network (FCS Net) and system network (KIC Net), the control network data and service data are separated, and the impact of man-machine operation on the formation of real-time automatic control system is reduced
Provide a variety of redundancy and fault-tolerant planning, and choose dual redundancy planning in important system components such as power supply, network, IO bus, control station CPU module, real-time server, history server, etc. Data synchronization planning according to the bus and software is selected to ensure that the switching is disturbance-free
Choose the C/S method, separate from data services and data use
Based on the deterministic real-time network data transmission, the unstable manipulation cycle due to network latency is reduced
Provide Level 2 algorithm functions, which can complete overall situation operations in Level 2, such as power station status, safety parameters, function calculation, overall situation alarm and other functions
Open data interface, providing a common data interface based on Ethernet and serial links
Through FMEA analysis and statistical data analysis, the key components and links that affect the reliability of the system are identified, and the overall reliability of the system is improved
Provide a variety of I/O interface protection circuit planning such as overvoltage, overcurrent, and filtering to avoid damage to the IO channel by transient signals
The interconnection signals related to the control or interlocking logic between different control stations are hardwired and blocked. Electrical barriers are used for signal and communication interconnections in different system zones or with different levels of security
Manipulation and chain logic completion take into account the diagnostic and fault-tolerant capabilities that are unique to digital systems
NC-DCS system requirements for industrial computers:
Fully sealed fanless, high-function, low-power control unit;
Strengthen the self-diagnosis plan, and detect the problem in time when the equipment has a serious problem;
Provide a variety of redundancy and fault-tolerant planning, and choose dual redundancy planning in important system components such as power supply, network, IO bus, CPU module of control station, real-time server, history server, etc.;
According to the deterministic real-time network data transmission, reduce the unstable control period caused by network delay;
Open data interface, high security function;
Convenient long-distance protection, easy protection, easy integration;
Conclusion
DCS Best Processing Unit Recommendation: EVOC MEC-5007
Because the price of nuclear power DCS products is very expensive, the manufacturing process of nuclear-grade automation products is very complex, and the requirements for system reliability are very high, which is a very urgent skill for localization.
It can be said that the nuclear power plant is the crystallization of human wisdom, and as the brain of the control of the nuclear power plant, DCS represents the highest level of science and technology, with the continuous development of computer skills and information automation skills, the intelligent control system integrating control, repair and skill management (ICMMS) has become the direction of the development of the power station instrumentation and control system. The control unit of this control system is no longer a simple sensor and controller, but an intelligent agent with certain autonomous control, data management and communication capabilities, industrial computer as a nuclear power DCS localization control unit, more highlighting its importance, trust that through our unremitting efforts, China's nuclear power work will become more and more mature, and at the same time, EVOC's products also play its due strength for the localization of nuclear power control system.
