【摘要】 为了研究±800 kV干式平波电抗器户内、外布置的可行性,基于该电抗器电感值的线性度较好不易饱和、运行维护简单等优点和现有运行经验,根据±800kV直流输电工程的初步方案和对相关制造厂调研,对换流站直流场中干式平波电抗器的户内、外布置方式技术、经济性比较。研究表明干式平波电抗器的户内、外布置方案均具有可行性。更多还原

【Abstract】 Smoothing reactor is one of key equipments in ±500kV HVDC projects.Compared with oil-immersed smoothing reactors,dry type ones have lots of advantages,such as,maintenance free,low-noise,and easy to be designed,produced and transported at home.So,dry type smoothing reactor is a rather better choice for HVDC.However,it is relatively less applied in today’s domestic HVDC projects.According to the transportation and manufacture capacity,the dry type smoothing reactor may be adopted in future 800kV UHVDC project.It is very important that the arrangement scheme of dry-type smoothing reactor in 800kV UHVDC project.Studying the principal parameters and system’s requirements of the 800kV UHVDC project,some main data can be gotten.Also,based on the characteristics and operation experience of dry-type smoothing reactor,the relative technical economy comparison of advantages and disadvantages for the reactor’s indoor or outdoor arrangement schemes had been put forward.Working with several main domestic manufactures,parameters for dry type smoothing reactor,such as,size,weight,cost of auxiliary equipments,etc.,had been collected by their concept design and experience.These data shows that,there will be less equipment investment and more operating cost when indoor arrangement scheme is adopted.In all,comparing outdoor arrangement with indoor arrangement,both schemes are feasible for ±800kV UHVDC project.As for one specified project,there shall be different commendatory schemes for different manufactures.The arrangement scheme shall be made after taking into account the factors,such as,floor area, construction investment,operating cost,etc.更多还原
