摘要

在超高压直流输电（EHVDC）已具备成熟技术基础上

进一步发展特高压直流输电

虽然可节省线路走廊

提高整个电力行业技术水平

但由于输送容量大

可靠性问题也愈显重要。一方面通过定性和定量对几种主要的接线进行分析

推荐出可靠性较高的接线

为特高压直流输电系统方案论证和系统设计提供了借鉴;另一方面

分析总结了已建±500kV换流站中各种典型故障原因及改善薄弱环节的措施

根据特高压直流输电工程特点

提出了提高特高压直流输电系统可靠性的措施

从而为新建特高压直流输电系统设计、运行和管理提供借鉴。

Abstract

Although developing the UHVDC transmission technology can save transmission corridor and enhance electric power industry technology based on the successful EHVDC technology

the reliability is more and more important due to its bulk capacity.The more reliable wiring of converter transformer and valve are recommended according to the detail analysis

on the other hand

the operation of some typical ±500 kV converter stations is reviewed and an overall analysis of fault cases is given.Based on the research on the features of ultra high voltage direct current system

the reliability of a practical ±800 kV project is evaluated in order to find the key factors that affect the system reliability significantly

and then some measures and methods are presented to enhance the reliability of UHVDC system.
