摘要
±800 kV特高压直流输电工程换流变压器的阻抗对整体绝缘设计、机械设计,以及换流站损耗、无功配置乃至换流阀的最大短路电流均有较大影响。以向家坝—上海±800 kV特高压工程为例,分析换流变阻抗对换流站设备参数和投资的影响,建立了数学模型,提出向—上工程换流变压器的短路阻抗合理取值范围。
The impedance of converter transformer in the ± 800 kV UHVDC Project produces great impacts on the whole insulation and mechanical design, as well as the converter loss, reactive power configuration and maximum short circuit current of valve. This paper makes an in-depth research on the impacts on the parameters of converter station equipment and investment based on Xiangjiaba-Shanghai project. A mathematical model is established, and the reasonable scope of impedance is proposed for the project.
