摘　　要：简述国内外特高压输电系统的发展运行情况,分析大型电源基地直接接入特高压输电系统的合理性和可行性,对大型电源基地直接接入特高压输电系统和经过二次升压接入特高压输电系统的经济性进行比较。结果表明,大型电源基地采用何种方式接入特高压输电系统需要根据实际情况确定,在不同的情况下采用不同的接入方式。The development and operation situation of ultra high voltage （UHV） transmission systems home and abroad are described in brief, the reasonability and feasibility of directly connecting bulk power base to power grid by UHV transmission system are analyzed, and the economy of the two connecting modes, i.e., directly connecting bulk power base with UHV transmission system and connecting bulk power base to power grid via twice step-up, are compared. Comparison conclusion shows that how to connect bulk power base with UHV power transmission system should be determined according to actual conditions, different grid-connecting modes should be adopted under different conditions.
