远距离大规模海上风电场送出方式综述

Summary of Transmission Methods of Long-distance Large-scale Offshore Wind Farms

我国海上风电正处于快速发展时期,海上风电开发已由近海浅水区向近海深水区甚至于远海逐步延伸,海上风电场呈现离岸越来越远、装机容量越来越大的趋势,这就对送出工程技术提出挑战。影响海上风电送出方式的相关因素有装机规模、送电距离、并网方式、海底电缆输电能力等因素。本文通过对比交流输电和柔性直流输电的应用场景和要求,提出合理的送出技术方案。分析、总结远距离大规模海上风电场的送出技术的研究现状并展望未来发展趋势。

My country's offshore wind power is in a period of rapid development.The development of offshore wind power has gradually expanded from offshore shallow waters to offshore deep waters and even far seas.Offshore wind farms are showing a trend of getting farther and farther from the shore and increasing installed capacity.Challenge the delivery of engineering technology.Relevant factors affecting offshore wind power transmission methods include installed capacity,transmission distance,grid connection method,and submarine cable transmission capacity.This paper compares the application scenarios and requirements of AC transmission and flexible DC transmission,and proposes a reasonable technical solution for sending.Analyze and summarize the research status of long-distance large-scale offshore wind farm transmission technology and look forward to the future development trend.
