摘要

柔性直流送出针对于深远海区域大容量海上风电有着显著优势，是实现深远海风电并网的有效方案。而我国在深远海区域海上风电送出研究尚处于起步阶段，与欧洲相比还有一定差距，目前关于±525 kV电压等级大容量的对称双极海风柔直系统研究还较为匮乏，文中基于欧洲知名电网运行商——TENNET公司的±525 kV/2 GW IJmuiden Ver海风送出项目，介绍了系统的对称双极典型拓扑结构、运行方式和主回路参数，以及不同的运行模式及其之间的转换关系等，并根据相关假设条件在PSCAD/EMTDC电磁暂态仿真平台中搭建了海上风电直流送出模型，对于系统在多种运行模式下进行全工况故障扫描，重点分析了海上换流站和陆上换流站的避雷器配置方案，最终根据绝缘裕度要求给出关键位置主设备绝缘水平推荐值，研究成果可为将来国内外类似电压等级的工程提供参考。

Abstract

Flexible DC transmission offers significant advantage for large-capacity offshore wind power in deep and distant sea regions

and is an effective solution for integrating such wind power into the grid. However

research on offshore wind power transmission from deep and distant sea areas in China is still in its early stages

and there remains a certain gap compared to Europe. Currently

studiess on large-capacity bipolar offshore wind flexible HVDC systems at ±525 kV voltage level are still relatively scare.In this paper

based on the IJmuiden Ver ±525 kV/2 GW offshore wind DC transmission project of TENNET Power Grid Company in Europe

the typical symmetric bipolar topology

operation modes

main circuit parameters

as well as different operating modes and their switching relationships of the system are introduced. Based on relevant assumption conditions

the offshore wind power DC transmission model is set up in thePSCAD/EMTDCelectromagnetic transient simulation platform. Full operating condition fault scans are conducted on the system under various operatign modes

with a focus on analyzing the arrester configuration schemes for the offshore converter station and the onshore converter station. FInally

recommended insulation levels for key main equipment are provided based on insulation margin requirements. The research results can serve as a reference for future engineering projects with similar voltage levels both at home and abroad.
