摘要
对两端超高压直流输电系统构成的单极系统、双极系统和背靠背直流系统等三种类型及其应用场合进行了分析和探讨,同时还讨论超高压直流输电系统换流站直流侧特征谐波和谐波抑制装置的选择以及功率因数的补偿等,最后给出超高压直流输电系统的主要优缺点以及重点需要解决的主要问题,并提出直流输电系统未来的发展前景。
In The unipolar system, bipolar system and DC system of three types, which are constituted by the two ends of HVDC system and their applications, are analyzed and discussed in this paper. Ultra high voltage direct current transmis- sion system in DC side harmonic selection of Harmonic suppression device and compensation of power factor are also dis- cussed. We not only give the main advantages and disadvantages of the High voltage DC transmission system, the keys are need to solve main problems, but also put forward the future prospects for the development of HVI）C transmission system.
