Abstract

With the continuous expansion of the scale of China's power system, higher and higher requirements are put forward for the security and reliability of the power system. Therefore, this article is aimed at the current situation that most power supply companies in our country use bus tie protection as a temporary protection method for lines to be put into operation, and need to cooperate with a large number of switching operations and extremely error-prone. This paper designs a kind of temporary protection device which can play a good role in the process of line operation. The PSCAD/EMTDC simulation software is used to verify that the protection device designed in this paper can not only reduce the operation link, but also reduce the risk of secondary equipment. It is of great practical value to improve the efficiency and ensure the safety of the line operation process.
