关于直流输电线路电压调整的研究

Research on Voltage Regulation of DC Transmission Line

直流输电时由于输电线路电阻,线路的损耗会产生电压降落,到达负荷点的电压会降低。文中分析介绍了直流输电的应用现状、直流输电的优势,提出了一种数学模型,研究探讨了由于线路传输电阻造成的电压降落的补偿问题,使负荷点的电压质量达到供电的要求。

Due to the resistance of the transmission line,the loss of the transmission line will cause the voltage drop when direct current transmit and the load point voltage will be reduced.This article analyzes the application and the status of direct current transmission and introduces the advantages of dc transmission compared with traditional ac power mode in modern transmission,and also makes a model to analyse how the compensation caused by transmission line voltage drop,making the voltage quality of load point achieve the requirement of the power supply.
