摘要
直流滤波器是特高压直流输电工程直流场重要成套设备之一,笔者在总结前期特高压直流输电工程系统研究结论的基础上,研究分析了+800 kV特高压直流输电工程直流滤波器设计需要考虑的关键问题,包括滤波器形式,直流侧谐振,要考虑的典型故障;介绍了用于计算直流滤波器典型故障的模型和方法。以云广+800 kV特高压直流输电工程为例,对直流侧谐振进行了校核,对直流滤波器设备暂态定值进行了计算。研究结果表明,云广±800 kV特高压直流输电工程直流滤波器设计是合理的,可满足直流系统安全可靠运行要求。
DC filter is one of most on the study result attained,this important equipment paper analyzes the installed in HVDC key issues of DC transmission project DC filed. Based filter design for ＋800 kV UHVDC transmission project,including the type of DC filter,resonance of DC side and typical faults of DC fiker,and introduces the models and methods for the typical faults calculation of DC filter. Yunnan-Guangdong ＋800 kV UHVDC transmission project being taken as an example,the resonance of DC side is verified and the transient ratings of DC filter components are calculated, showing that the design of DC filter of the project is reasonable, and it can meet the requirement of the project operating safely.
