摘要
±800kV特高压直流输电工程是目前世界上电压等级最高的直流输电工程,其中的一些技术问题不仅是中国电网前所未有的,而且是世界电网发展史中前所未有的,开展特高压直流输电关键技术试验研究是保证工程成功的关键。中国电力科学研究院依托特高压直流试验基地,将开展一系列的特高压直流输电技术研究,包括电磁环境研究、空气间隙绝缘特性研究、带电作业研究、污秽外绝缘特性研究、特高压设备运行特性和设备长期带电考核等。该文对特高压直流试验基地主要设备,以及与此相关的研究工作作了详细介绍。
±800kV UHVDC project is the highest voltage classes DC transmission project in the world now, some technical problems of this project are strange not only in Chinese power grids, but also in the world power grids. The key insuring the success of this project is to take test researches on the key technique of UHVDC. Relying on UHVDC test station, China electric power research institute （CEPRI） will carry through series of researches on UHVDC technology, including researches on electromagnetic environment, insulation characteristics of air gap, live line working, pollution external insulation characteristics, operation characteristics of UHV equipments, and evaluation of equipments energized power long term, and so on. Main equipments of UHV DC base and the related research works are introduced.
