摘要
根据直流输电技术发展及其在我国电力系统中长期发展规划中的应用前景,提出为直流输电系统划分电压等级标准化序列的思想。详细论述了直流系统划分序列的必要性和依据,在此基础上确定电压等级序列组成,比较各电压等级的经济性,得出各自的适用范围。最后,针对具体案例分析了不同电压等级直流系统在规划电网中的适用性,对直流输电进一步发展需解决的问题进行了论述。
According to the technical progress in HVDC transmission technology and its application in mediumlong-term developing program of power system in China, the idea of dividing different voltage grades is proposed to form DC voltage class standardized series. The necessity and evidence of forming the voltage class series are analyzed, and the economy of each voltage grade is compared to present the applicable range of HVDC transmission systems. Finally, application examples of different voltage grade HVDC transmission systems are analyzed in some practical cases, and the future problems of the HVDC transmission development are discussed.
