Research and Application of Non stop Power off Technology for 10kV Line Protection and Measurement Control Device Transformation 新稿
To address the engineering challenge of equipment being overdue for service but unable to be shut down for renovation
a technical solution for non-stop renovation based on virtual bay bypassing has been proposed. By setting up a virtual bay and using bypass operation
the seamless switching of protection automation functions of the operating bay is achieved
enabling the entire process of removing old devices and installing new ones to be carried out without power interruption. The scheme innovatively develops core technologies such as live current loop series connection and cross-connection
and non-stop transmission and verification
establishing a complete technical system for non-stop renovation of 10kV lines. This technology aims to reduce power outage time
effectively solve equipment renovation problems
significantly enhance power supply reliability
provide important technical support for the construction of smart grids
and promote the development of non-stop operation technologies in the power industry.
