Become the first in China, the first in Datang Group, and the DCS DEH system "100% autonomous and controllable" "Unit. The 660MW ultra supercritical coal-fired unit of Datang Nanjing Power Plant #2 unit was put into operation in December 2010. The original host DCS system used the I / a series control system manufactured by Shanghai fox Polo Co., Ltd. and the original DEH system used the sppa-t3000 system produced by Siemens. Up to now, the operation time of the control system has exceeded 10 years, the DCS failure rate has increased year by year, and it is difficult to purchase spare parts. This transformation has been demonstrated in the early stage for more than one year With careful preparation, it took more than 20 days to complete the wiring, commissioning, trial operation and startup of more than 12000 thermal signal points in 44 cabinets. The new generation of 100% autonomous and controllable intelligent distributed control system NT6000 V5 of Keyuan wisdom is adopted to completely replace the imported control system, so as to realize the one-time national production and complete replacement of DCS, DEH, ETS, meh and MetS systems of domestic ultra supercritical units. At the same time, on the basis of self-control, based on the technical applications such as big data analysis, artificial intelligence and advanced control technology, the advanced control strategies of Datang Nandian, Datang East China Institute and Keyuan intelligence have been collected, and the intelligent control applications such as intelligent early warning, equipment diagnosis, combustion optimization and one key control have been expanded. The manual monitoring has been gradually replaced by machine monitoring, which greatly reduces the workload of operation and operation, and realizes intelligent monitoring. 1、 Main innovations of project application 1 Based on the dual core parallel computing environment of the controller, the network security algorithm is built in the controller, and the multi protocol parallel communication and encryption authentication technology are adopted to improve the security protection ability of the DCS system, which has passed the Achilles secondary certification. 2. Based on the open source RTEMS, a high real-time autonomous embedded real-time operating system (RTOS) is developed, which realizes the transplantation and Application on multiple platforms such as arm, PowerPC and MIPs, and provides strong support for the development of high real-time application functions such as network security and DEH control. 3. A real-time synchronous scheduling strategy is developed to realize the redundant synchronous operation between different architecture controllers (DPU), avoid the failure of redundant system caused by common faults, and improve the flexibility of supply chain. 4. A method to quickly adjust the oscillation frequency of power chip according to the feedback voltage is proposed, and a highly reliable switching power supply with ultra wide voltage input range is developed. 5. A semi physical simulation system for dynamic verification of control strategy in static environment is developed to analyze and optimize the control system strategy and shorten the on-site debugging time. The successful operation of the project has laid a solid foundation for solving the current strategic problems of independent and controllable major equipment, accelerating the construction of energy security and realizing high-quality development for China Datang Group, completely replacing 100% independent and controllable DCS system in China's energy industry, and realizing the strategic planning of economic power. 2、 On July 24, the China Society of automation organized and held the project technical appraisal meeting of "development of self controllable DCS system based on domestic software and hardware and demonstration application on 660MW ultra supercritical unit" in four main (sub) venues in Beijing and Nanjing in the form of "on-site + video". The project, jointly undertaken by Datang Nanjing power plant, Datang Group Science and Technology Research Institute Co., Ltd., East China electric power test and Research Institute and Nanjing Keyuan Smart Technology Group Co., Ltd., has successfully passed the appraisal of scientific and technological achievements. After the test and evaluation of the power generation automation professional committee of China automation society, the appraisal expert group agreed that the overall technology of this achievement has reached the international advanced level, among which the switching power supply design technology and analog card anti-interference technology have reached the international leading level. It can be further popularized in various types of thermal power units (including 1000MW secondary reheat units). 3、 After the successful operation of the whole network screen brushing project, the initiative of self-control was highly recognized by Datang Nandian and Datang Group. The website of the Central Commission for Discipline Inspection and China Electric Power News praised it one after another, and the screen brushing reports of industry associations and industry media triggered an upsurge of self-control systems in the whole industry. 1. Users highly praised Datang Group and Datang Nanjing power plant for releasing the report on operation at the first time, conveying the significance of independent and controllable transformation to the whole industry. The technical transformation and commissioning of the cabinet were completed in a total of more than 20 days, and the high technical transformation and commissioning of the cabinet were completed in more than 12000 days. 2. The official media praised the website of the Central Commission for Discipline Inspection: "Datang Nandian, together with Keyuan wisdom, took the lead in completing the construction of version 1.0 of coal-fired" smart power plant "in the domestic power industry. Datang Nanjing power plant was rated as an" advanced unit for the construction of scientific and technological innovation system of power enterprises ". At present, the two sides are actively building version 2.0 of "smart power plant" represented by intelligent combustion real-time optimization control and intelligent control of coal handling system. In addition, in order to realize the independent control of industrial control equipment, as the first pilot of Datang Group, China Southern Power once again joined hands with Keyuan wisdom to take the lead in carrying out the transformation of DCS (distributed control system) independent control projects in the national power industry, and strive to solve the "neck" problem of key technology. " China Electric Power News and China industry news network highly affirmed the significance of the autonomous and controllable DCS project. "The operation of the project lays a solid foundation for solving the strategic problem of autonomous and controllable major equipment, accelerating the construction of energy security and completely replacing 100% autonomous and controllable DCS in China's energy industry." 3. The new initiative of independent and controllable screen brushing in the industry has led to screen brushing reports. Polaris power, control network, power circle, thermal power personnel, thermal power plant technology alliance, China Power Equipment Management Association Network, smart energy industry alliance, power engineering and many other industry media and associations have intensively released it, causing an upsurge of independent and controllable DCS in the industry.
