摘要
Abstract
With the rapid development of renewable energy in recent years in China,submarine cables are being widely used in offshore wind power and island interconnection.Similar to land cables,the selection of grounding methods for submarine cables is also a problem.However,due to the unique structure and laying environment of submarine cables,the selection of grounding methods and the positioning of groun-ding points for submarine cables with lengths ranging from a few kilometers to dozens of kilometers in sea-bed sections,intertidal sections,and landing sections are significantly different from land cables.The author aims to explore and solve this issue.The author also proposes a method to calculate the induced voltage and current for various grounding methods commonly used in submarine cables using the EMTP(Electromagnetic Transients Program)and verifies the results through a comparative study using the Comsol multiphysics finite element simulation software.Additionally,the correctness of the EMTP model is validated through practical engineering cases.关键词
