Abstract

The Zhoushan 500kV interconnection project is the first power transmission line using 500kV XLPE submarine cables in the world. In the 500kV submarine cable withstand voltage test, due to the long length of the submarine cable line and the high operating voltage, in order to ensure the safety and stability during the submarine cable test, it is necessary to perform real-time comparison and calculation of the voltage at both ends of the submarine cable. In this paper, a dual-terminal voltage video synchronization monitoring technology is adopted to transmit the voltage information of the far end of the submarine cable to the near end in real time through the Internet, thereby realizing the data synchronization of the submarine cable withstand voltage test. The field test results prove that the scheme can meet the design requirements and provide a guarantee for the safe operation of the submarine cable test.
