摘要
基于贵州福泉变电站输电线路融冰电流的计算结果,对500 kV/220 kV线路配置了60 MW/25 MW直流融冰装置,并给35 kV/10 kV典型线型设计了500 kW柴油发电机为电源的移动式直流融冰装置。应用PSCAD/EMTDC仿真软件研究了这些融冰系统以证实其可用性、有效性以及对直流融冰装置所建议的技术指标。
Based on the de-icing current calculation of Fu-Quan substation transmission lines, the 60 MW/25 MW DC de-icer is deployed to 500 kV/220 kV lines, and for 35 kV/10 kV lines a mobile DC de-icer is designed, which can be driven by 500 kW diesel power generator. The DC de-icing systems are studied with PSCAD/EMTDC to prove their feasibility and effectivity as well as the recommended specifications of the DC de-icers.
