The project of "Independent controllable DCS system development based on domestic software and hardware and demonstration application on 660MW ultra-supercritical unit" is the common result of Datang Group and Keyuan Wisdom bravely undertaking and actively innovating under the background of severe international situation and industrial control safety alarm bells.
2010-2019 / Embark on layout, key breakthroughs
Long-term accumulation, gradually improve the localization rate of NT6000, and the original system can be mixed networking, replace each other.
2020 / Demonstration Application
On March 11, it applied for datang group's key scientific and technological projects to solve the "card neck" problem, and carried out technical research and demonstration applications with the goal of DCS and DEH control systems of 660MW ultra-supercritical units of Datang Nanjing Power Plant No. 2;
On May 9, the company completed the compilation of dcs and controllable technical specifications and technical standards for datang Nanjing power plant;
On October 21, Datang Nanjing Power Plant HVAC System, DCS autonomous controllable controller pilot;
On November 9, Datang Nanjing Thermal Power Co., Ltd. replenishment water system, DCS autonomous controllable controller pilot;
On November 18, the engineering design of DCS independent controllable system of Datang Nanjing Power Plant was completed.
2021 / Successful commissioning
On January 15, the design, optimization and simulation test of DCS autonomous control scheme of Datang Nanjing Power Plant were completed;
On May 6, the demonstration application project of the completely autonomous and controllable intelligent control system of The No. 2 ultra-supercritical unit of Datang Nandian Power Plant was successfully put into operation and stable operation.
01 Zhang Zhigang, deputy director of the Science and Technology Innovation Department of Datang Group, delivered a welcome speech.
02 Situ Yougong, deputy director of Datang Nanjing Power Plant, made a project work report.
03 Cao Ruifeng, vice president of Nanjing Keyuan Smart Technology Group Co., Ltd., made a project technical report.
04 Zhang Lei, thermal control specialist of the Technical Department of Datang Nanjing Power Plant, made a user report.
05 Zhang Xing, Institute of Thermal Control, East China Electric Power Test and Research Institute, Datang, made a technical and economic analysis and benefit report.
06 Yang Zhenyong, member of the appraisal committee and director of the State Grid North China Electric Power Research Institute, made a test report.
07 Niu Yuguang, member of the Appraisal Committee, professor of North China Electric Power University, and secretary general of the Intelligent Power Generation Professional Committee, made a new report on science and technology investigation.
08 Li Yuqi, deputy general manager of Datang Jiangsu Power Generation Co., Ltd., spoke on behalf of the project unit.
During the questioning and answering stages of the experts, the experts of the appraisal team conducted a strict review of the technical details. Experts expressed their appreciation for the project unit's long-term investment and innovative spirit around the goal of achieving independent and controllable, and said that the project is the first set of independent controllable control system in China's power market, which is a very good, successful and valuable result, and has important demonstration significance for the wide application of the independent controllable system, hoping that the project unit will further strengthen the project technology innovation condensation from the perspective of the industry on the basis of this achievement, and make greater contributions to promoting the overall development of the industry.
The 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.
Appraisal certificate of scientific and technological achievements
The main innovations of the project:
1) Based on the controller dual-core parallel computing environment, the network security algorithm is built into the controller, and the multi-protocol parallel communication and encryption authentication technology are used to improve the security protection capabilities of the DCS system and pass the Achilles secondary certification.
2) Based on the open source RHEMS, the autonomous embedded real-time operating system (RTOS) with high real-time performance has been developed, which has realized the porting and application of multiple platforms such as ARM, PowerPC, MIPS, etc., and provides strong support for the development of high-real-time application functions such as network security and DEH control.
3) Developed a real-time synchronous scheduling strategy to achieve redundant synchronous operation between different architecture controllers (DPUs), avoid common failures caused by redundant system failures, and improve the flexibility of the supply chain.
4) A method of rapidly adjusting the oscillation frequency of the power supply chip according to the feedback voltage is proposed, and a highly reliable switching power supply with ultra-wide voltage input range is developed.
5) Developed a semi-physical simulation system for dynamic verification of control strategies in a static environment, which is used to analyze and optimize control system strategies and shorten the on-site debugging time.
This project is the first application of the autonomous controllable DCS system based on 100% domestic devices and all independent control of the source code in China.
Under the meticulous organization of Datang Nanjing Power Plant, Datang East China Electric Power Test and Research Institute and Keyuan Wisdom, the project demonstration application completed the full-scale transformation of 660MW ultra-supercritical units including DEH and ETS within 22 days, and was successfully put into operation at one time, creating a new record for the replacement of DCS transformation period of the same type of unit. Datang East China Electric Power Test and Research Institute invested elite forces, based on the control strategy and optimization algorithm accumulated over the years, carefully configured and meticulously debugged, and played a key role in the technical lead unit. Since the system was put into operation, the operation has been stable and reliable, the control performance is excellent, and the social and economic benefits are remarkable.
Appraisal experts agree that it can be further promoted on various types of thermal power units (including 1000MW secondary reheat units).
The successful convening of the appraisal meeting completed the authoritative appraisal of "independent controllable DCS system development based on domestic software and hardware and demonstration application on 660MW ultra-supercritical units", which is of great significance to solving the urgent problem of independent control of major equipment, ensuring national energy security, and ensuring that core major equipment is not controlled by people.
In the future, Keyuan Wisdom will continue to focus on scientific and technological innovation and research and development in the field of industrial control, and vigorously promote the application of autonomous controllable systems in the fields of electric power, energy, chemical industry, metallurgy, rail transit, etc., so that autonomous controllable systems can exert greater economic and social benefits.
