China's Liaoning Power Grid is moving towards intelligence, the first 220kV fully digital substation is put into operation
On November 8, the 220kV Dashiqiao Primary Substation of Liaoning Company was officially put into operation after renovation. After the station was put into operation, a fully digital substation was realized, which met the requirements of unattended operation, reduced the number of equipment maintenance and the probability of failure, and ensured continuous power supply to users. In recent years, with the rapid economic development of Yingkou area, the electricity load has also increased rapidly. As an important hub for power transmission in the region, the 220 kV Dashiqiao Substation of Yingkou Power Supply Company is also bearing more and more heavy loads. It is urgent to carry out large-scale transformation to improve the operation reliability of the substation, so as to ensure the rapid economic development of the Liaoning coastal economic belt-Yingkou area. At the same time, this is also a solid step for Liaoning Power Grid to develop into an intelligent power grid.
