特高压直流控制保护系统设计与开发

摘要

随着特高压技术的发展,直流输电凭借其优越性而被广泛应用.针对当前直流输电出现的控制保护难点,文中通过对特高压直流输电一般使用的主回路接线方法的研究,分析了特高压直流控制保护的技术要求.较详细地分析了该类系统结构特点、控制方法、控制手段的设计和保护整定.此外,具有针对性的对特高压直流控制保护系统做出了一个较为科学的设计.%With the development of ultra high voltage technology , DC power transmission is widely used because of its superiority. In view of the current of HVDC control and protection , this paper UHV DC transmission project. The main circuit wiring characteristics , analyzes the HVDC control protection system and conventional DC difference and special requirements , and of the control and protection system overall structure, control strategy, stratification and redundancy, control function allocation and protection configuration conducted a comprehensive analysis and research , and puts forward the HVDC control protection system design scheme.
