In the industrial background where the growth of power demand is slowing down and the proportion of new energy installations is constantly increasing, the construction of smart power plants has become a new "breakthrough point" for enterprises. When cloud computing, Internet of Things, big data, artificial intelligence come in succession, how will they play?
The "First Domestic Smart Power Plant" halo overhead, Datang Taizhou Thermal Power Company (hereinafter referred to as "Taizhou Thermal Power") located in the corner of Jiangnan, has recently ignited.
As the first smart power plant in China to introduce Internet +, big data, digital decision-making, and digital management, Taizhou Thermal Power is refreshing. In just one year, there were endless stream of Chinese and foreign companies visiting, with a total of more than 300 people.
Scan the corresponding QR code to instantly retrieve the file information of the device; after generating intelligent "two tickets" and virtual electronic fences, fundamentally eliminate maintenance and misoperation; through 3D modeling process simulation training, realize real maintenance in the virtual Training effect; monitor the activity trajectory of the entire plant through precise personnel positioning ...
On April 26, in the Taizhou Thermal Power Plant area, which had just been completed for one year, the reporter of Energy actually experienced an application scenario of “the first smart power plant in Chinaâ€.
"As the first smart power plant in China, this model is very popular in the power industry." Wang Binghua, general manager of Datang Taizhou Thermal Power Co., Ltd., introduced to the reporter "Energy".
In fact, with the implementation of the “in-depth integration of the two technologies†policy of national informatization and industrialization, the construction of smart power plants has become a new “breakthrough point†for enterprises under the industrial background in which the growth of power demand is slowing down and the proportion of new energy installations is increasing. ".
According to the "Energy" reporter's statistics, after Datang Taizhou Thermal Power and Guohua Jingyang Thermal Power, Huaneng Group, Huadian Group, China Guangdong Nuclear Power, China Resources Power and other power giants are not far behind, and have entered the new format of smart power plants.
For a time, whether it is coal power, gas power, hydropower that is traditional energy power generation, or rapid development of wind power, photovoltaic, nuclear power and other new energy power generation, new and old power plants seem to be undergoing a new round of "wisdom" baptism.
It is worth noting that experts, scholars, enterprises and other parties still have different opinions on the practice of smart power plants. At the same time, the various smart power plant templates that have sprung up in China have different specific practices and different opinions.
In May, "Energy" reporters went to Beijing, Jiangsu, Guangdong, Guangxi, Qinghai and other places, trying to clarify the development status, mode, and direction of smart power plants, focusing on the two main lines of smart power plant theory and practice, and trying to clarify smart power plants. The fog of this new concept.
Different opinions, wisdom concept
The birth of any new thing is always inspiring, but it is often accompanied by fierce discussion and controversy, as is the smart power plant.
"Since 2012, I have been a project manager for the intelligent construction of power plants. I have been exposed to a lot of construction experience inside and outside the industry, but I have not yet found a unified standard. I think the most urgent thing is to form a basic consensus within the industry, of course not Absolute unity. "On May 10, in the office plant of the State Energy Investment Group Guohua (Beijing) Gas and Thermal Power Co., Ltd., Yan Jidong, the director of the Party Construction Administration Department, confessed to the" Energy "reporter.
In its opinion, what is intelligence? What is wisdom? There is no unified statement in the industry.
Where did the concept of smart power plants come from? The reporter tried to search the literature and found that this concept originated from the announcement of a new business such as the addition of smart power plants by a company called Keyuan Co., Ltd. in 2015.
According to the announcement, the “smart power plant†in Keyuan ’s eyes is based on the digital power plant, using Internet, Internet of Things, artificial intelligence, big data analysis, cloud computing and other informatization, virtual reality and other technologies to In-depth mining with the data will eventually achieve a safer, more efficient, less-employed, greener, and more profitable intelligent production operation.
On May 8-9, Shi Yubo, executive vice chairman of the China Energy Research Association, held the "2018 Smart Power Plant Forum (Phase 1)" jointly organized by the Energy Conservation and Emission Reduction Center of the China Energy Research Society and the National University Science Park of North China Electric Power University. It also said: "The essence of smart power plants is the highly developed and in-depth integration of information technology and intelligent technology in the field of power generation, which is mainly reflected in the systematic application of technologies such as big data, Internet of Things, visualization, advanced measurement and intelligent control. The core is information fusion and intelligent power generation technology. "
At the same time, in the view of Liu Jizhen, academician of the Chinese Academy of Engineering and former president of North China Electric Power University, the prospect of intelligent power generation is broad. It is defined as: based on automation, informatization, and standardization in the power generation process, with management and control integration, big data, and cloud The platform and the Internet of Things are platforms, intelligent sensing and execution, intelligent management and learning, to achieve more safe, efficient, clean and low-carbon production goals.
"From the perspective of the enterprise, I think it is better to describe the power plant intelligently." Chen Bin, director of operations and management of China Resources Power Holdings Co., Ltd. admitted, "If you use wisdom, you should pay attention to the entire value chain, operating decisions, The electricity sales market and the coal macro market combine production and market operations organically. "
In addition, Zhang Jinbin, chief engineer of digital design of Southwest Electric Power Design Institute of China Electric Power Engineering Consulting Group, believes that the smart power plant is oriented towards the full life cycle of the power plant, using a new generation of information and communication technology, artificial intelligence technology, detection technology and control technology, etc. It must be the whole link; it can also be seen as a combination of information and communication technology (ICT), operation and maintenance technology (OT), engineering technology (ET), management technology and artificial intelligence (AI).
Regarding the mixed situation of smart power plants, Chen Jie, general manager of Zhuhai Tonghai Technology Co., Ltd., also expressed his views in an interview with the reporter of "Energy".
"Previously, the China Electricity Council issued a guideline for smart power plants, basically from the perspective of thermal engineering; from the perspective of electrical appliances, there may be an electrical perspective; there may be a management information system perspective in the management system; more emphasis is placed on the school It is algorithm and modeling. "Chen Jie said," I think that in the early stage of smart power plants, it should be the same as the management of the Internet. It is difficult to say that a standardized thing has to be developed because many applications have not yet erupted. Different professions have different understandings, it is difficult to say who is right. "
Initial layout of power giants
Although smart power plants are still in the early stages of exploration, the pace of power giants is clearly faster.
It is understood that Datang Taizhou Thermal Power Company mainly consists of five basic modules, which are three-dimensional visualization-based operation and training system, Internet + -based production management system, expert-based fault diagnosis system, big data-based analysis and optimization system, Decision-making system based on digitization.
"The first module is a three-dimensional visualization-based operation and training system, taking virtual power plants as an example. Our virtual power plant is based on the two-dimensional drawings provided by Jiangsu Electric Power Design Institute and the three-dimensional model of some pipelines. The three-dimensional scanning of the machine equipment to form a high-precision, equal-scale three-dimensional modeling, which is highly consistent with the actual plant layout and equipment, and truly realized an all-round smart power plant. "Wei Zhijun, Secretary of the Party Committee of Datang Taizhou Thermal Power Co. Reporter introduction.
In its view, the precise positioning of the staff in the three-dimensional virtual power plant can realize the monitoring of the activity trajectory of the entire plant area, and in-depth expansion of this function, the realization of intelligent point inspection, intelligent two-ticket management system, etc. On the one hand, it can reduce the safety accidents caused by human reasons, on the other hand, it can greatly improve the safety of production management and achieve effective management and control.
"Taizhou Thermoelectricity has realized the transformation from" civil defense "to" technical defense ". Taking intelligent spot inspection as an example, the system realizes real-time monitoring and process visualization of spot inspectors. The on-duty personnel can see the advance The set inspection route, the duty supervisor and management personnel can view the personnel's walking trajectory and inspection process in real time in the 3D virtual power plant; it can also trace the historical inspection process afterwards to automatically realize the inspection quality inspection "Wei Zhijun said," In the process of spot inspection, the inspectors use the mobile phone APP to scan the QR code of the device, check the item inspection items of the device one by one, and record the data. When the device is found to be abnormal, Defects can be registered directly through the mobile APP, and sounds, videos, pictures, etc. can be uploaded at the same time. At present, the intelligent spot inspection function has been fully put into use. "
In fact, as the first crab-eating enterprise, Datang Group has also built a new generation of coal-fired smart power plants at Datang Nanjing Power Plant after building "the first smart power plant in China."
"The functions of each module of the smart power plant are still in the initial stage of the smart power plant, and there are still many areas that need to be improved." Qian Yujun, deputy director of the technical department of Datang Nanjing Power Plant, admitted.
Obviously, in this round of competition, Datang of the five major power generation groups won the first mover advantage. It is worth noting that during the interview, the reporter of Energy learned that China Resources Power's development ideas have also been recognized by people in the industry to varying degrees.
It is reported that China Resources Power has proposed that the single-plant model is difficult to be intelligent. The data volume of a plant is not enough to support the intelligence of a power plant. The historical data and cases of the power plant are not optimal. If there is no unit or power plant of the same type For comparison, it is impossible to determine whether the current operating parameters are optimal, so the starting point cannot be high.
"I think that China Resources Power's CSASS monitoring and operation platform may need to be given full attention. This is what we do with Siemens. The core is to change the competition of the single factory to the competition of the group. After the data of the single factory is aggregated, the group of experts can solve Analyze the common problems. "Chen Jie said," Including the centralized procurement of materials by the China Resources Group is now a major trend. The ultimate purpose of informatization is to improve efficiency, improve management and services, but only connect information and pile up data. It is meaningless. It is the ultimate goal of informatization, intelligence and intelligence to gather data and concentrate on generating benefits for management. Therefore, we must vigorously study centralized monitoring and operation and maintenance systems, which is obvious in management. improvement."
Unlike the application of smart in coal or gas power, the combination of smart and nuclear power industry seems to be more advanced. On January 13, 2017, the National Energy Administration released the "Thirteenth Five-Year Plan for Energy Technology Innovation". Among them, the construction content of the National Energy Applied Technology Research and Demonstration Project "Smart Nuclear Power Operation System Research and Demonstration Project" was included.
"Planning" requirements: In the field of nuclear power, it should be carried out in many fields including demonstration projects of modular small reactors, demonstration and application of key technology for life extension of nuclear power plants, research on new generation advanced nuclear fuel technology, research on nuclear power plant operation and maintenance technology, etc.
As one of the most complex industrial systems, nuclear power plants have a crucial impact on the level of operation and management technology to improve the safety level and power generation capacity of nuclear power plants. And smart nuclear power operation has gradually become the development trend of advanced operation technology of nuclear power.
It is understood that China Guangdong Nuclear Power, one of the three major nuclear power groups, started the construction of smart power plants as early as 2013. After the project was upgraded in 2015, it was changed to smart nuclear power and ranked one of the group's five strategic special projects. So far, an intelligent project with a full chain and full life cycle from the source of engineering design to operation and maintenance decision-making has been preliminarily established.
"In the field of nuclear power equipment, the application of big data and artificial intelligence has already achieved initial results, but how to apply new technologies reasonably and efficiently still needs to be explored. In the next step, we will focus on exploring equipment failure feature extraction, monitoring and early warning, and failure Diagnosis, fault development prediction, health assessment, operation and maintenance strategies, etc. "Huang Lijun, director of the RCA Research Institute, the experience feedback of the Equipment Management Department of Suzhou Thermal Engineering Research Institute, admitted.
In addition, smart technologies are also being tried and applied in the field of hydropower. National Energy Group is using Guodian Daduhe River Hydropower Development Co., Ltd. as a pilot to carry out the exploration and practice of "smart enterprises", trying to integrate new technologies such as cloud computing, big data, Internet of Things, mobile Internet, artificial intelligence and traditional power companies Deep integration.
"In smart applications, hydropower first. In October 2017, the National Energy Group identified eight companies including thermal power, hydropower, and wind power as pilot units." Kang Long, deputy director of the safety production department of the National Energy Investment Group Co., Ltd. revealed.
Should avoid "one step"
Now that the project is striving for layout, the implementation of the smart power plant cannot be "one-step".
"Smart power plants are by no means an upgrade of automation, but an improvement in capabilities. Therefore, the core essence is to reflect the wisdom and use some of the human brain power to supplement, strengthen, and even surpass through big data cloud computing and other technologies. I I think this is a big direction for the next step. "Yan Jidong said.
In its view, from the existing practice of smart power plants, everyone is more working in a single power plant, but the intelligence and even the role of wisdom should be a geometric level change. If a power generation group can centralize the data of each power plant, then the degree of data mining and availability is not an order of magnitude compared to a single power plant.
As the first "smart power station" demonstration project of the State Energy Investment Group Guohua Power-Shenhua Guohua (Beijing) Gas Thermal Power Plant, the smart power station is divided into four layers: intelligent equipment, intelligent control, intelligent management and integrated cloud platform. The equipment and the control layer have jointly constructed a digital expression of the production process. On this basis, intelligence has a lot of room to play in equipment early warning, operation optimization, and security protection.
"If intelligence can give equipment accurate and reasonable cracking prediction in condition maintenance and provide accurate and reliable guidance, it will undoubtedly bring inestimable economic benefits." Yan Jidong said.
Also in terms of algorithms, the current pain point is that there is too little sample space, such as gas turbines, and the OEM has a large amount of data, so the algorithm given is relatively accurate. Although the domestic algorithm is not unadvanced, but the sample space is small, the improvement of the algorithm is relatively weak, and it may take a long time to complete this algorithm. So this confirms the value of the group's scale to do this work from the side, because the algorithm research from the data volume of the group level can undoubtedly go further.
In addition to traditional energy, the photovoltaic and wind power industries use single equipment, centralized models, and are widely distributed and highly automated. In addition, it has the advantage of latecomers. Emerging industries can use a large number of information technologies. Traditional power plants often put into production for a long time and make intelligent transformations. A series of tasks from the front end to the back end are relatively complicated. Therefore, the intelligentization of photovoltaic wind power is relatively easy.
"The automated information system of China's power generation enterprises has a very good technical foundation, and it will also become an important support and carrier for the construction of smart power plants in China." Si Fengqi, deputy dean of the School of Energy and Environment of Southeast University, suggested, "With the development of technology The smart power plant itself is also abundant, and it is definitely not a one-step process. You should rely on the advantages of the existing big data and equipment feature models to pick up the 'watermelon' first. "
Monocrystalline solar panels have a higher efficiency rate in generating electricity from light and are a more space-efficient solution. Durable, long living and aesthetically pleasing, these cells are the ideal solution for residential and small commercial rooftop installations.
