At the 7th Electric Industry Development Summit Forum recently attended by reporters, focusing on “smart grid†has become a major topic for equipment-related industries.
All participants in the conference are members of the industry. Whether they are experts from the Ministry of Science and Technology, the National Development and Reform Commission, the Chinese Academy of Sciences, or more than one hundred representatives of electrical companies, they are fully aware of the smart grid blueprint of the smart grid and even the State Grid Corporation of China.
But they also want to learn more. The smart grid needs smart devices to support it. Now that the smart grid is moving from concept to reality, is the power equipment smarter? Is the smart power equipment R&D route correct? This is a problem that everyone cares about. This forum just created an opportunity.
Smart Grid "IoT", Power Equipment "Traceable"
What kind of life does smart grid bring to people? Different people paint different scenes. Some power technology researchers believe that in the era of smart grid, the power grid should be "self-healing," not only able to eliminate hidden dangers, but also be able to quickly resume operation after a breakdown; ordinary people who visited the Shanghai World Expo pay more attention to the smart grid belt. Convenient living, such as going out, can also control the home's electrical appliances.
These maps are very beautiful. However, for Cai Guoxiong, a smart grid expert and deputy chief engineer of the Chinese Academy of Electric Power, he is more willing to associate the smart grid with the Internet of Things.
Cai Guoxiong gave an example with his own experience. He raised the apple phone in his hand and said, "This is what my daughter bought for me. The order that was placed on the Internet a week ago was received yesterday."
“A few days ago, I asked my daughter, where was the phone ordered? My daughter checked on the Internet and told me that I had already arrived at the Capital Airport.†Cai Guoxiong said, “The position of this mobile phone is always clear, that is, The entire transportation process is always in a traceable state. The 'object' is traceable, which is a major feature of the Internet of Things."
Why is the "thing" traceable in the Internet of Things? The reason is that "thing" and "people" are interacting. Cai Guoxiong’s daughter pays attention to this cell phone, not the other; the mobile phone is reflected in every aspect of the transportation process.
Cai Guoxiong believes that smart smart grids should also achieve "material" traceability and realize the interaction between "materials" and "people." This puts forward new requirements for electrical equipment: Is the electrical equipment traceable? Can you interact with the operator?
Smart power equipment means that every transformer, reactor, high-voltage switch, etc. within the power grid can be distinguished by the operation and management personnel; and the information such as the location, operating status, and service life of these devices can also be clearly informed. Operation manager.
The reality and the gap between the ideal and the ideal are traceable and interactive. It is the requirement of the smart grid for electrical equipment. But everyone is very clear that this may take a while to be realized. Cai Guoxiong therefore hopes that electrical companies "at least for now, each power device has a unique IP address." In this way, at least the operation manager can identify each different device.
Cai Guoxiong's words let the equipment companies on the scene see the gap between products and real intelligence. A company representative asked the experts: “What is the cause of this situation? Is it the lack of technical strength of the company or the lack of product foresight?â€
Experts believe that electrical companies do not have sufficient service awareness and are a major source of problems. Only with a sense of service, electrician companies can keep up with the pace of user development.
The "service awareness" here does not mean after-sales service. Lu Yantao, a former deputy director of the Ministry of Machinery Industry and a special advisor to the China Federation of Machinery Industry, said that the so-called “service awareness†means that electrician companies must consider what users want and consciously satisfy the requirements of users for continuous improvement.
Take the transformer as an example. Building a smart grid requires on-line monitoring of the transformer in order to understand its operational status in real time. Currently, on-line monitoring methods generally install sensors at specific locations within the transformer, but so far, most companies have not considered whether to embed sensors when manufacturing equipment or to allow space for users to install sensors.
Huang Qiang, chief expert of the China Academy of Railway Sciences, had similar experience in the study of electrified railway technology. "When doing research, we hope that companies can provide small and sophisticated equipment. Small, not small equipment, but small production volume. But many companies said that can not be provided. For example, we need 100 parts, companies can not do, only We can order 10,000."
For the lack of awareness of services, corporate representatives believe that there are objective reasons. Many companies started from the 1980s and retained the concept of "planning" in the original planned economic system. Coupled with the fact that power grid construction has been hot for many years, most of the power equipment products are in short supply, which has delayed the transformation of the company's concept from the "plan" to the "market."
The concept of "planning" in service awareness is the question of the company's way of thinking. In addition to this, Lu Yanyi also mentioned the issue of R&D environment in enterprises - the combination of "production, study and research," but not "use", is obviously insufficient.
“Industry-University-Research†is an important method for Chinese enterprises’ scientific research, and many scientific and technological achievements have thus emerged. However, "production, study and research" and "use" are often separated, and "production, research, and use" have not yet been universally carried out in China.
The facts have proved that "production, research and application" are more effective. At the end of 2008, the State Grid Corporation of China held a symposium to summarize the development experience of UHV equipment. The relevant leaders of the national ministries and commissions, the experts of the State Grid Corporation of China, and the person in charge of electrician companies all agreed that the combination of production, teaching, research and application is the most important experience.
Lu Yanlu said that from "production, study, and research" to "production, research, and use," not only is there more party involved in the change, but also a change in philosophy: what to buy from what to do, and what the company needs to do to the customer. Experts hope that the company can reach a higher level in the future: what the customer needs in the future and what the company will do now.
Although there is still a gap between the requirements for electrical equipment and traceable and interactive equipment, the “smart†equipment may be promising. However, it is gratifying that electrician companies have been exploring the right R&D routes.
A change is that electrician companies are increasingly focusing on user needs and developing corresponding products. One person familiar with the development and research and development of TBEA's R&D technology said that Hengqin had understood the customer's request for reserved sensor space and was trying to develop a product that could preset sensor placement points.
Another change is that some manufacturers have already made explorations on the identification of electrical equipment. In the upward UHVDC project, ABB provided technical support for converter transformers and also provided a monitoring device. Similarly, Nantong Hyosung also developed a substation integrated automation system to try to resolve transformer monitoring problems.
The progress of equipment requires standard support. As a support for the R&D of equipment, the standardization of research and development of smart devices is also ongoing. Lu Hao, Director of the Standards Department of China Electrical Appliance Industry Association and Director of the Beijing Institute of Electrotechnics and Economics, assured the delegates that the standardization of the electrical industry will be carried out in a timely manner in accordance with the development of the smart grid.
Lu Hao said that they will cooperate with relevant departments and power grid companies to increase standardization work in the smart grid field. For example, in the smart grid equipment sector, they have set up a sub-committee on smart grid equipment and plan to start the transmission and distribution in two aspects, and then fully start.
Deputy Minister of the Ministry of Science and Technology, deputy director of the research office Luan Heping said: "We will face a long period of product upgrading process, which is an intelligent process." "Smart" power equipment is the inevitable development, companies need to do is to shorten the realization of time.
