特高压直流换流站绝缘配合软件的开发与应用

摘要

根据特高压直流换流站绝缘配合的基本方法和工程设计要求.利用Excel及其自带的VBA编辑器开发了一套特高压直流换流站绝缘配合设计与计算软件.该软件具有避雷器配置方案的选择、修改和保存参数、计算绝缘水平、避雷器特性曲线查询等功能.该软件应用于某±800 kV特高压直流换流站的绝缘配合设计与计算中.实例验算表明该软件具有计算灵活、快速、准确、操作方便、界面友好、通用性强等特点.%According to the basic insulation coordination method of UHVDC converter station and the requirements of engineering,a design & calculation software is developed for it with Excel and its VBA editor,including different functions,such as the selection of arrester arrangement scheme,modification and storage of parameters,calculation of insulation level,inquiry of arrester characteristic curves,etc. It is used in the design and calculation of insulation coordination for a ±800kV UHVDC converter station. Case study shows that it is flexible,fast,accurate,convenient,user-friendly and adaptable.
