摘要
针对目前直流线路的直流融冰方法研究现状,提出了一种基于双24脉波不控整流器的直流融冰装置,可以通过改变整流变压器二次侧电压档位以及整流器输出连接方式来扩大装置融冰范围。给出了详细的直流融冰装置设计方案,在PSCAD/EMTDC仿真软件中搭建了直流融冰装置模型,仿真结果验证了设计的有效性。
ABSTRACT： According to the research status on DC de-icing method for DC transmission lines, a kind of DC de-icing device was designed based on double 24-pulse non-controlled rectifier, which could expand the ice-melting scope by changing the secondary voltage of rectifier transformer and the connection types of rectifier＇s output. The detail design scheme of this DC de-icing device was proposed, and its model was built in simulation software PSCAD/EMTDC. The simulation results have verified the effectiveness of the design.
