What is the development of smart power plants in China and which power groups are doing it? Are there any benchmarking projects?

First, forced by reality, smart power plants are an inevitable trend.

China is rich in coal, but poor in oil and natural gas. Hydropower development cycle is long, nuclear power is unstable, and new energy is conceptualized. Thermal power still accounts for more than 60% of electric energy, and the burden of domestic power supply still falls on traditional power plants.

Development has entered a new normal, and the two should be deeply integrated. Electric power enterprises urgently need to change extensive management mode, promote system, management and scientific and technological innovation, cultivate new growth advantages, strengthen management and control, reduce costs and increase efficiency, and improve enterprise management level and core competitiveness.

The government of China demands that both the environment and the economy should be dealt with, and both should be hard. Under the double pressure, focusing on the upgrading of existing power plants, the rise of smart power plants not only conforms to the development of the times, but also is the only way for traditional power enterprises to change themselves.

Second, the definition, characteristics and technical route of smart power plants

At present, the definition of smart power plant can be said to be a hundred schools of thought contend, and there is no unified conclusion. Many scholars have put forward different views.

Liu, chairman of Keyuan, believes that smart power plants are the further development of the combination of digital power plants and intelligent systems. It will be supported by new sensors, Internet of Things, artificial intelligence and virtual reality, focusing on innovative management concepts, professional management systems, humanized management ideas and integrated management platforms. It has the characteristics of digitalization, informationization, visualization and intelligence, and will maximize the safe, economical, efficient and environmentally friendly operation of the power plant.

Mr. Wang Peihong of Southeast University believes that smart power plants are supported by technologies such as informationization, digitalization and intelligence. Intelligence is knowledge, which has three characteristics: perception ability (the ability to obtain external information), memory and thinking ability (the ability to store information and think to produce knowledge), learning ability and adaptability (learning and applying knowledge).

The Outline of Smart Power Plant Technology Development points out that smart power plants integrate intelligent sensing and execution, intelligent control and management decision-making technologies on the basis of widely adopting modern digital information processing and communication technologies to realize safe, efficient and environmentally friendly operation and coordinate with smart grid.

According to Li of North China Electric Power University, smart power plants are supported by six management systems: executive system, information system, energy-saving and environmental protection system, early warning system, learning enterprise system and corporate culture system, which are the inevitable products to adapt to China electric power reform.

2. Standard characteristics of smart power plants

A standard smart power plant should have five characteristics: starting from perception, being good at calculation, being good at decision-making, being diligent in execution and being good at learning.

Three. Analysis of Main Suppliers of Digital Power Plant/Smart Power Plant

Siemens: an international giant. At present, the main cutting-in methods are three-dimensional digital modeling and gas turbine system diagnosis, and provide three-dimensional digital files. The diagnostic function of gas turbine system is excellent, but the integration of three-dimensional model with information system and management system involves less and costs more.

Peng Rui Science and Technology: It switched from the original PDMS sales, and its digital power plant construction mainly depends on its three-dimensional modeling ability. For example, the Jingneng Gaoantun gas turbine power plant, which it participated in, adopted three-dimensional modeling+file model.

Keyuan Co., Ltd.: Thermal control and power plant information business started, and each functional module of smart power plant is relatively perfect, which is well integrated with information and management system. At present, the performance is the most. Its participation in Datang Jiangyan, Datang Nandian and other projects is mainly due to the organic integration of different functional modules according to the needs of power plants, which is feasible.

IV. Summary of Smart Power Plant Demonstration Project of Domestic Power Group

At present, domestic power generation groups are actively launching smart power plants and erecting model projects.

Datang group

Datang Group has been at the forefront of smart power plant construction in China through the construction of key smart power plant model projects such as Datang Jiangyan Smart Power Plant and Datang Nandian Power Plant. In 20 16, China Datang, Southeast University and Keyuan Co., Ltd. signed a strategic cooperation agreement on collaborative innovation in Industry-University-Research, and the three parties will explore the construction mode of Datang Group's smart power plant and smart energy group on the important components of smart power plant.

Datang Jiangyan Intelligent Power Plant

The first intelligent power plant in China. Its smart power plant model includes five functional modules: safety production management system based on internet plus, operation optimization system based on big data analysis, 3D visual fault diagnosis system based on expert system, 3D digital archives and 3D visual intelligent training system. Because of its symbolic significance, online information is more open:

Datang Nandian Intelligent Power Plant

There are eight functional modules in its smart power plant planning: three-dimensional digital archives and visual three-dimensional equipment model, boiler CT, intelligent combustion and intelligent coal blending, intelligent emission, cold end optimization of steam turbine, fault diagnosis and accident prediction, safety production management system based on internet plus, and intelligent management and control center. It is reported that the condenser cleaning robot, as the optimization part of the cold end of steam turbine, has been put into use, and the boiler CT part will also be launched in the near future. After the whole intelligent power plant system is completely completed, it will become the first intelligent coal-fired power plant in China.

Jingneng group
