Overcome the "nucleus" of the smart grid and build a leading smart transformer
Experts have described to us the smart life of the future many times: in the office, they receive text messages from home, notifying the immediate status of home appliances such as air conditioners, TVs, refrigerators; Smart life needs the support of the smart grid, and the realization of the smart grid is inseparable from the smart transformer.
The smart transformer is the core equipment of the smart grid, and the improvement of its technical level has a huge role in promoting the construction of the smart grid.
In 2012, three new-generation smart transformers developed by Shandong Dianke Electric Group passed the performance test. The successful development of smart transformers was regarded as an important achievement in 2012 by Shandong Dianqi Electric Group.
Plan ahead to develop smart transformers
State Grid Corporation is accelerating the construction of a strong smart grid. To meet the needs of the development of smart grids, transformers and other equipment must first be intelligent, that is, interactive management with the grid system to realize the visualization of equipment status, network and automation of control terminals, and ensure that equipment is in safe, reliable, and economic conditions Run down.
"This is a combination of strong and weak electricity, and the modern sensor technology, measurement and control technology, and information network technology are effectively applied to the technological innovation of power equipment. Compared with traditional transformers, the development of smart transformers needs to break through many key technologies and problems." The technical expert of Shandong Electrician Electric Group said.
In 2007, Shandong Electric Power Equipment Co., Ltd., a subsidiary of Shandong Electrical Engineering Group, began to develop smart transformers. At that time, smart transformers were just a vague concept, and Shandong Electric Power Equipment Co., Ltd. adopted a "small-step brisk" development strategy to break through the key technologies of smart transformers one by one.
On October 31, 2011, the 220 kV smart transformer was successfully applied in Weifang Yiming Substation, the first smart substation in Shandong Province. At the same time, Changzhou Toshiba Transformer Co., Ltd., another company affiliated to Shandong Dianke Electric Group, has also made significant progress. It has successfully developed the first 220 kV smart transformer and the first 500 kV smart transformer in China, which have been applied in China. The first 220 kV (Xijing) and 500 kV (Changchun South) smart substations.
Overcome the new generation of intelligent variable technology problems
With the development of the power grid, the State Grid Corporation has proposed a plan to build a new generation of smart substations, which put forward higher requirements for the performance of smart transformers. In December 2011, the company held two meetings on "Intelligent High Voltage Equipment Testing and Testing", clarifying that the transformer manufacturer must be responsible for the entire intelligent transformer (transformer body, sensors, and intelligent components) and possess the ability to test and test intelligent transformers. This points out the direction for the development of smart transformers and puts forward new requirements. For enterprises, opportunities and challenges coexist.
The personnel of the Technology R & D Center and the Test Center of Shandong Denko Electric Group form a joint research project team for smart transformers, and carry out technical research in accordance with new requirements. On the one hand, they conducted a demand survey on the intelligent detection system of the intelligent transformer to determine the required test and detection equipment. On the one hand, they integrated the resources within the group to form an overall combat and joint research work situation.
In May 2012, during the performance test of the 220 kV smart transformer, the project team members followed the test for 7 consecutive days, from equipment wiring, installation, configuration, commissioning to the final test, without any moment of relaxation. When the test results reached expectations, a smile appeared on everyone's face. Wang Xingang, the main designer of smart transformer R & D, said: "Only we know how much bitterness and perseverance are behind the success."
In May 2012, under the witness of experts from China Electric Power Research Institute, the one-time test of 220 kV new-generation smart transformer was successful. This is the first smart transformer certified by the State Grid Corporation of China. In July and December, two other products also passed the test, marking that Shandong Dianke Electric Group is fully capable of manufacturing and testing 220 kV and 110 kV smart transformers.
"We want to accelerate the pace of technological innovation, increase the intensity of scientific and technological projects, and develop new products that are more in line with the requirements of smart grid development." Facing the future, Zhao Qichang, general manager of Shandong Electrician Electric Group said confidently.
