Recently, the State Grid Zhejiang Jiaxing Power Supply Company completed the commissioning of the 20-kilovolt static var generator (SVG) device at the Zhouquan 110-kilovolt substation. Hu Xiaodong, a staff member, explained that the equipment can achieve voltage regulation in as fast as 5 milliseconds.

This marks the first local initiative to independently implement such an engineering project. The new equipment has transformed the traditional crude switching mode of capacitors, achieving stepless precision compensation to suppress voltage fluctuations and harmonics, ensuring the operation of industrial precision equipment.

This technological breakthrough not only strengthens regional power supply during peak summer demand but also provides voltage support for wind and solar power grid integration, enhances renewable energy absorption, facilitates the construction of a new power system, and lays a solid foundation for achieving carbon neutrality goals.
