特高压直流换流站系统优化设计

Optimal Design for UHVDC Converter Station

为使特高压直流换流站系统在经济上和技术上均达到一个更优的组合,全面总结了向家坝-上海±800kV特高压直流工程的咨询研究结论,系统阐述了该工程的技术方案,包括电气主接线、直流谐波抑制及直流滤波器设计,过电压及绝缘配合、主设备要求以及融冰运行方式等关键技术问题,并通过工程建设的开展以及特高压输电技术研究的深入对上述技术方案的进行了全方面的优化。换流站系统优化设计对高压直流技术的发展和设备的研发及特高压直流工程的建设具有重要的指导意义。

Based on the consultation and study for Xiangjiaba-Shanghai ± 800 kV UHVDC project, we presented the optimal design for key technique solutions, including the DC system electrical scheme design, DC filter design and DC harmonic component suppression, over-voltage and insulation coordination, requirements for converter station equipment and de-icing operation design. According to development of the project construction and UHVDC technology, the UHVDC system design for the converter station comes to an optimal combination . These optimal design conclusions are important for developing HVDC technique and equipment, providing a reference for UHVDC project construction.
