摘要

超高压直流输电系统由于其输送容量大、距离长、损耗小

输电线路只需正负两极线路

杆塔结构简单

占地面积小等优点

目前在中国已经得到越来越广泛的应用。笔者从空载加压试验的一般规定及接线方式开始

阐述了直流输电的换流原理及开路电压计算公式的推导。针对±500 kV贵广直流输电系统双极空载加压试验

比较分析极1和极2的试验数据后

得出结论

极1与极2的直流输电线路在长时间运行后存在一定的不对称性

极1与极2的控制方式影响触发角。

Abstract

UHVDC transmission system because of its large transmission capacity

long distance

low loss

the transmission lines just positive and negative poles lines

simple structure

small site area etc

at present in our country has been more and more widely used.This paper

from the general provisions of the no-load energization test and start wiring way

this paper expounds the principle of HVDC flow changing and open voltage calculation equation of.According to±500 kV Gui-Guang HVDC transmission system bipolar no-load energization test

compares pole 1 and pole 2 test data

draw the conclusion

there are certain asymmetry in pole 1 and 2 DC transmission lines after a long time operation

the control mode of pole 1 and 2 affects firing angle.
