The world's first set of three gradual controllable reactors independently developed by Xi'an Xidian Transformer Co., Ltd. was officially connected to the grid at the 500kV switch station in Zhangzhou, Shanxi. At the operation site, the product can automatically realize 25%, 50%, 75% and 100% capacity adjustment according to the line load change, which plays an important role in the efficient, safe and reliable operation of the power transmission and transformation network.
It is understood that reactors are the key equipment in the transmission process of the grid. In the past, the capacity of conventional reactors produced in China was not adjustable during operation. When the line delivers more power, it will cause the system voltage to decrease, affecting the safety and stability of the power grid and the power quality. The graded controllable reactor successfully developed by Xichang has the advantages of convenient capacity adjustment, fast response time, no harmonic generation, low noise, vibration and loss. Especially in the long-distance transmission for ultra-high voltage and ultra-high voltage power grids, the superiority is more prominent, which will be of great significance for the nationalization of electric equipment in the construction of national million-volt ultra-high voltage power grid.
