巴西能源中心与负荷中心相距较远,亟须建设远距离、大容量、低损耗特高压的输电线路,实现能源资源优化配置。巴西是拉丁美洲最大国家,其国土面积850多万平方公里,居世界第5位。人口约为2亿,居世界第5位;人均GDP1.26万美元,是世界重要的新兴经济体之一。多样性是巴西能源资源的典型特征。1999年能源的初级生产结构为:水电占42%,石油占27%,包括木炭、酒精、蔗渣等的生物能源占24%,天然气占6%,煤占
Brazil’s energy center is far away from the load center. It is imperative to build transmission lines with long-distance, large-capacity and low-loss UHV to optimize the allocation of energy resources. Brazil is the largest country in Latin America with a land area of over 8.5 million square kilometers, ranking fifth in the world. With a population of about 200 million, ranking the fifth in the world; GDP per capita is 12,600 U.S. dollars, making it one of the most important emerging economies in the world. Diversity is a typical feature of Brazil’s energy resources. In 1999, the primary production structure of energy was: hydropower accounted for 42% and oil accounted for 27%. Bioenergy including charcoal, alcohol and bagasse accounted for 24%, natural gas accounted for 6% and coal accounted for
