摘要:
柔性直流系统凭借其独特的技术优势,正逐渐成为大规模远距离海上风电并网的主流方案。鉴于国 内外相关研究较为匮乏,文中针对用于海上风电并网的柔性直流系统,详细研究了其中的过电压和绝缘配 合问题。首先介绍了用于海上风电并网的柔性直流系统的基本情况,包括拓扑结构、站内主要设备和接地 方式。然后根据实际情况详细介绍了过电压和绝缘配合的基本原则,包括典型故障选取、电压观测点选取、 避雷器的配置方案和参数选择方法。再基于电磁暂态仿真平台PSCAD/EMTDC,搭建了国内某规划海上风 电场的±320 kV/1 100 MW柔性直流送出系统仿真模型;基于时域仿真,研究了柔性直流系统的过电压特性, 并且基于提出的避雷器的配置方案,给出了柔性直流换流站的主设备绝缘水平。研究成果填补相关领域研 究的空白,可为未来国内类似工程提供重要的参考依据。
Abstract:
With its unique technical advantages,flexible DC system is gradually becoming the mainstream scheme for large?scale offshore wind farm integration. Considering the lack of related research at home and abroad,this pa? per analyzes the overvoltage protection and insulation coordination of flexible DC system on this occasion. First,the basic layout of the flexible DC system is introduced,including the topology,the main electrical equipment in con? verter station and the grounding schemes. Second,basic principles for studying the overvoltage protection and insula? tion coordination are discussed,which mainly involves the selection of the typical fault,the voltage observation point,and the configuration scheme of arresters. Last,based on a planning ±320 kV/1 100 MW flexible DC system for wind farm integration,the simulation is carried out on PSCAD/EMTDC,and the overvoltage characteristics are studied. The paper also determined the insulation levels of the main electrical equipment. The research conclusions fill the gap in this field,which could serve as an important reference for similar practical projects in the future.
