Xiaoshan Power Grid's first direct-supplied digital substation was put into operation

Recently, the first digital substation in Xiaoshan, the 110 kV Shunfeng substation in Qianjiang Century City, has been successfully put into operation. The digital substation means that all equipment and functions in the station are built on a unified information platform. During each link, information transmission is realized through digital streams. The speed of propagation, signal loss, and reception efficiency are good, allowing the grid to be more “smart”. Responds to instructions. For example, when a tripping accident occurs, the grid can automatically “identify” the tripping cause and speed up the reclosing speed, thereby further improving the reliability of the power supply in the region.

It is understood that the 110 kV Shunfeng substation with a capacity of 16 kVA put into operation was the first step for Xiaoshan Grid to build a digital substation. Next, the Xiaoshan Power Supply Bureau will continue to promote the construction of digitalized substations. It is expected that by 2050, our district will achieve full digital substation coverage. At that time, digital substations will also be connected with power fiber optic homes and smart homes, and they will be linked together into a unified, strong smart grid. At the same time, the 110 kV Shunfeng transformer was the first 110 kV direct supply 20 kilovolt transformer substation in Xiaoshan Power Grid. Its operation broke the traditional 110 kV supply for 35 kV and then transferred 10 kV for the "three levels." The substation mode not only reduces the scale of investment in power grid construction, but also provides more land resources for the development of the city. It also has the same effect as the digital substation, and further improves the reliability of power supply by reducing transformer losses.
