摘要
云南小湾水电站总装机容量4200MW,将采用直流输电方式向广东送电,设计直流输电容量为3000MW,输电距离约1500km。根据国内外直流输电工程现状,结合直流输电线路的导线截面选择,对小湾水电站直流输电应采用±500kV还是±600kV电压等级向广东送电进行了研究,并对采用±600kV直流输电电压的可行性进行了分析。
The total installed capacity of Xiaowan Hydro Power Station in Yunnan Province, China is 4200MW and the electrical energy generated by this power station will be transmitted to Guangdong Province with DC power transmission. The specified DC power transmission capacity is 3000MW and the power transmission distance is about 1500km. According to the present situation of DC power transmission home and abroad and considering the selection of conductor cross-section for DC power transmission lines, the voltage class for DC power transmission from Xiaowan Hydro Power Station to Guangdong Province, i.e., 500 or 600kV should be adopted, is researched and the feasibility analysis of using 600kV for DC power transmission is carried out.
