一、前言 利用潮汐发电是现代世界上比较新的科学技术之一,也是我国水电事业发展的新方向。地球上的潮汐能量约有400亿(瓦千),而地球上全部河流经济位能仅有10亿(瓦千),所以潮汐能量是十分巨大的。 潮汐发电站的修建,不仅具有重要的经济意义,而且为地质工作者提供征服海洋的途径。我国海岸线长达11000公里。这为潮汐发电创造了有利条件,仅山东海岸就长约2000公里,可建立潮汐发电站百余座,装机容量约为200万(瓦千),相当于两个三门峡的发电量。
I. Introduction The use of tidal power generation is one of the newer science and technology in the modern world. It is also a new direction for the development of hydropower in our country. The tidal energy on the earth is about 40 billion (watts), while the earth’s entire river economic position can only 1 billion (thousands of thousands), so the tidal energy is very huge. The construction of tidal power stations not only has important economic significance, but also provides geological workers with ways to conquer the oceans. Our country coastline up to 11,000 km. This has created favorable conditions for tidal power generation. Only about 2,000 km of Shandong coast can be built, and over 100 tidal power stations can be built with an installed capacity of about 2 million (TWD), equivalent to the power generation of the two Sanmenxia.
