我国电力工业发展很快,到2006年底为止,总装机容量已达到6亿kW以上,发电量超过2220亿kWh以上。然而高峰用电量和低谷用电量之间的反差日益增大,已经达到2:1或3:1甚至更加悬殊的地步,迫切需要缓解。用于电力平衡调峰填谷最好办法是建设抽水蓄能电站,然而在过去长达半个世纪的历程中我国的建设状况远远不能满足需要,几乎 China’s power industry has developed rapidly. By the end of 2006, the total installed capacity has reached over 600 million kW and the power generation capacity has exceeded 2,220 billion kWh. However, the contrast between the peak electricity consumption and the low electricity consumption has been increasing. It has reached an even greater disparity of 2: 1 or 3: 1 and there is an urgent need to alleviate it. The best way to balance the peak load and reduce the grain-filling power is to build a pumped-storage power station. However, in the course of half a century, the construction status of our country can not meet the needs. Almost
