广东某大型高压直流换流站海绵城市措施适用性及设计分析

Analysis on the Applicability and Design of Sponge City Measures for a Large HVDC Converter Station in Guangdong

高压直流换流站是高压电网电力交换的重要节点工程,换流站具有占地面积大、硬化面积大、绿化面积少、高压特种设备多等特点,如何兼顾换流站站区的安全性与环境的协调性成为设计的难点。基于此,文章结合广东某大型高压直流换流站项目,在分析站区特点的基础上,从生物滞留设施、雨水收集调蓄或回收利用、屋面雨水断接等方面,对此类高压直流换流站的海绵城市措施选择与设计进行了简要分析,并换流站海绵城市措施应用效果,以资借鉴。

HVDC converter station is an important node project for power exchange in high voltage power grid.The converter station has the characteristics of large area,large hardened area, small green area and many high voltage special equipment. How to balance the safety and environmental coordination of converter station area has become a difficult point in design. Based on this, combined with a large HVDC converter station project in Guangdong,based on the analysis of the characteristics of the station area, this paper briefly analyzes the selection and design of sponge city measures for such HVDC converter stations from the aspects of bioretention facilities, rainwater collection and storage or recycling, roof rainwater disconnection, etc., and the application effect of sponge city measures in converter stations for reference.
