| Abstract: | 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. |
