摘要
Abstract
Compared to AC transmission system, HVDC transmission system has been relatively rapid development and application in the world and within our country with its unique advantages. However, due to with a large number of the system into operation and the rapid development, many problems need to be solved in practical engineering applications are also highlighted. Since HVDC transmission line is longer, it increases the probability of line failure, thereby reducing the power grid safety and reliability. Therefore, to improve the safety and reliability of operation of HVDC system has very important significance for security and stability of the entire grid. This paper compares the existing advantages and disadvantages of traveling wave protection methods and problems in the application of practical engineering, proposes a new method of traveling wave protection based on HHT, and provides a theoretical basis for further research of HVDC transmission line traveling wave protection.关键词
