火的使用以及其伴随而来的光亮使人类进入文明社会,电的使用使人类进入现代社会。由于西藏自然条件、历史和经济社会发展水平等原因,西藏电网发展滞后,电网规模、覆盖面小,供电人口少,电力紧缺矛盾一直比较突出。目前,西藏农牧区用电主要依靠主电网延伸供电及主电网外小水电、太阳能光伏电源供电。今年6月,国家电网公司与西藏自治区签订了《关于共同加快推进无电地区电力建设的协议》和《关于西藏自治区国家电网覆盖区域农电代管框架协议》。通过无电地区电力建设 The use of fire and the light that accompanies it have brought mankind into a civilized society, and the use of electricity has brought mankind into the modern world. Due to the natural conditions in Tibet, historical and economic and social development, the development of Tibet power grid lagged behind. The scale of power grids, the small coverage, the small power supply population and the contradiction between power shortage have been outstanding. At present, the electricity in Tibet’s rural areas and herdsmen’s relies mainly on extending the power supply of the main grid and the small hydropower and solar photovoltaic power supply in the main grid. In June of this year, State Grid Corporation of China and the Tibet Autonomous Region signed the “Agreement on Accelerating Jointly Accelerating the Construction of Electricity in Areas without Electricity” and the “Framework Agreement on the Management of Rural Power in the Areas covered by the National Grid of the Tibet Autonomous Region.” Through electricity-free areas of power construction
