Correspondent Fu Hongjie Wang extension / China Industry News reporter by the celebration Recently, Harbin Electric Group Co., Ltd. Harbin Electric Group Co., Ltd. successfully signed the National Grid Eastern Power Co., Ltd. Ximeng converter station to install the camera project to adjust the camera host contract. This advanced technology, which has no precedent in the world, will provide State Grid Corporation with the first batch of new products to ensure the safe and stable operation of UHV power grids. Uncover the mystery According to reports, the first phase of the State Grid converter stations installed into the camera project is divided into two parts by the end and the receiver, which send 8 sets of camera will be all transferred by the Ha motor supplier. Except for the project of Ximeng, Jiuquan, Zarroute and Yazhong will also sign and complete the transfer procedures for the three projects and begin the formal implementation. The first host will be completed before August 2017. reason. Since April this year, a network vote on the "third national card" has flourished. Of the more than 2 million netizens, nearly half of them chose the card "ultra high voltage" spontaneously. UHV is the world's most advanced transmission technology, with long-distance, large capacity, low loss, less comprehensive advantages of land, power transmission is the "highway." With the formal implementation of the State Grid's first batch of camera project contracts, Harbin Electric Machinery Co., Ltd. used this advanced technology to help the construction of UHV transmission projects and ensure the safe and steady delivery of power to millions of households, building a solid foundation for this "expressway." With the rapid development of UHV AC and DC power grids and the large-scale development of clean energy, profound changes have taken place in the operational characteristics of the power grid. The interaction between the transmission and reception ends affects the operational characteristics of the power grid. The chain reaction mechanism of AC and DC faults is complicated. Once the DC system Failure, will absorb a large amount of reactive power from the grid, and may even cause regional voltage depression, to bring significant impact on the safe operation of the grid. In order to ensure smooth and reliable operation of the power grid, it is crucial to build a new type of camera to solve the problem of reactive power and voltage and play the role of "Dinghai Shenzhen". Satisfied with the answer sheet PR. In the early years, people occasionally brought up the camera, the tone seems to be mixed with an old decline, because this product has long been widely replaced by static var compensator. However, as the "13th Five-Year Plan" has been gradually clarified, the State Grid explicitly proposed that it should adhere to the principle of large DC transmission and strong reactive support, and accelerate the planning, construction, operation and management of dynamic reactive power compensation devices. And in the construction of the DC project to send, by the end of the region, and Beijing and other large areas outside the power of the construction of a number of camera group. At this time, the camera has been given a new meaning and mission, must have millisecond-level dynamic reactive power compensation capability and excellent phase-in ability to protect the grid voltage stability, safe and reliable operation. Ha electrical learned about the relevant market demand, immediately set up a technical research team, has focused on adjusting the camera performance more than a dozen special studies, the summary became more than 10 words of special reports. As the chief technology officer responsible for adjusting the camera project, Wang Yanyin recalled the memory of the situation at that time: Because the market demand was very urgent, technicians were racing with time every day to study, discuss, simulate, simulate, and count every second. As of early April 2016, the camera technology research team completed an initial development and design of the camera at an alarming rate and delivered a satisfactory answer. At the same time, Haadian Group and Ha-machine leader attaches great importance to the project of State Grid Transfer Camera and visited the State Grid Corporation many times to understand all the needs of the owners in an all-round way. Through frequent interaction and in-depth exchange with the owners, HEPHM, while satisfying the needs of the owners, put forward and developed the modernized and intelligent functions such as one-key start-up of the units and unmanned equipment, etc., so as to truly achieve the goal of customers. Smart manufacturing climbing new high height. The reason why the state network camera project is different from the traditional camera, because of its high degree of transient performance concerns and stringent requirements. Coincidentally, the impact generator specially designed for short-circuit tests also has similar requirements. As the only manufacturer in China that has the capability of designing and manufacturing large-capacity impact generators, Harbin Electric has accumulated a great deal of technology and experience in the theoretical analysis and structural design of the transient motor. It has played an important role in the formulation of camera technology, parameter setting and early design process, effectively promoted the rapid progress of the camera project and won the acclaim from the owners and experts. Due to the special working mode of the camera, in order to obtain the satisfactory operation performance, the choice of cooling mode is the key to solve the problem. Judging from the high electromagnetic parameters selected by the camera, it seems easier to solve the problem of cooling with water cooling. However, since air-cooling has the advantages of simple structure, high safety and reliability, low manufacturing difficulty and easy maintenance as compared with water cooling, Adjust the cooling needs of the camera, of course, is a better choice. Therefore, Ha motor researchers resolutely choose the latter, relying on the company in large air-cooled units of the research and experience and advantages for more than 20 kinds of rotor ventilation structure of a large number of simulation and comparative calculation of the various components of the air-cooled program Temperature rise has been fully demonstrated, and ultimately determine a reasonable rotor structure and electromagnetic parameters, the smooth solution to the problem of cooling the camera.
