With the development of ultra-high voltage and UHV power grid construction, for longer transmission lines, in order to limit the power frequency and operating overvoltage, high-voltage reactors need to be arranged on the line. However, the conventional high-voltage shunt reactor is not adjustable. When the line transmission power is close to natural power or more power is transmitted, the system voltage is lowered, which affects the safety and stability of the power grid and the power quality, and limits the line transmission capability. The graded controllable shunt reactor developed by Xichang Company has the advantages of convenient adjustment, fast response time, no harmonic generation, low noise, vibration and loss. It is used for long-distance transmission of ultra-high voltage and UHV power grids, and has superior advantages and broad market prospects. It is reported that this group of high-tech new products is ordered by State Grid Corporation for the 500 kV switch station in Shanxi Yinzhou. It is planned to be completed by the end of May 2006.
Xichang independent research and development exchange level controllable reactor will produce
A group of three 500 kV and 50,000 thousand single-phase AC class-class controllable reactors, which were independently developed by Xi'an Xidian Transformer Co., Ltd., are basically completed in the design stage and will be put into production. The technical performance of this product has reached the international advanced level, and has obtained the preliminary examination and approval notice for the invention patent application of the State Intellectual Property Office.
